The aim of the measurement was to verify the drawbar characteristics of chosen tractors with different undercarriages. The tractors were of the same engine power as well as type of gearbox (PowerShift – gears full shifted while loaded). We were dealing with the wheeled tractor John Deere 8320 and crawler tractor John Deere 8320RT. The measurement was implemented in the land register of Vrbovec (Znojmo region) in an area where green peas were grown as the main product and winter wheat as the preceding crop. The measured and the counterproductive tractors were interconnected by the rope containing strain-gauge force sensors. The wheeled tractor was decelerated by the tractor crawler. The tractor crawler was decelerated by two wheeled tractors. The wheeled tractor’s stress-strain properties were also measured applying two pressure rating alternatives. Variant A presented inflation pressure of 160 kPa on the front axle and of 140 kPa on the rear axle. Variant B applied inflation pressure of 120 kPa on the front axle and of 100 kPa on the rear axle. Measured and calculated findings reveal that the tractor crawler achieved higher drawbar power and lower specific tractive consumption and traction slip than the wheeled tractor with both variants of inflation. Comparing the stress-strain characteristics of the wheeled tractor with a different tire inflation illustrates that using variant B, higher drawbar power and lower specific tractive consumption and traction slip were measured.

The paper presents a comparison of pulling properties of a prototype of three-axle tractor 6K6 with the classical tractor John Deere 8400. To compare differences in the contact surface of wheels the authors measured the area of tyres of tested tractors. It was found out that the contact surface of tyres of 6K6 tractor was larger by 62 % than that of John Deere 8400. Results of measurements performed on a stubble indicated that the drawbar pull force of 6K6 tractor was 70 kN while that of 4K4 only 58 kN (slippage of wheels was in both cases 40 %). It was concluded that although the weights of both tractors were comparable, a greater drawbar pull force of 6K6 tractor resulted from a larger contact area of tyres with soil surface. The maximum drawbar power of 6K6 tractor was measured at the speed ranging from 13 to 17 km.h-1. In case of John Deere 8400 tractor, the maximum drawbar power was recorded at speeds of 9 to 13 km.h-1.Wheels of the prototype 6K6 tractor were tyred with tyres 480/70 R 30. The equation of slippage curve was derived on the base of measured results and the coefficient of adhesion.

AbstractSkidding of large-sized logs requires special machinery such as skidders, clambunks, forwarders or farm tractors with a winch or hydraulic tongs. The precise choice of which skidding machine to use depends largely on the desired efficiency and economic factors. The aim of this research was to evaluate the suitability of three different machines (LKT 81 skidder, John Deere 1110D forwarder and Pronar 1221A agricultural tractor with hydraulic tongs) for wood skidding based on technical and economic indicators. The practical work for this research was carried out in the Mirosławiec Forest Division in areas with fresh mixed coniferous forest habitats where the dominant species in the stands was pine and strip-like clear cutting was the preferred management practice.The best machinery performance values were obtained for skidding using the John Deere forwarder.

Abstract The paper explores the efficiency of tractor track scarifiers that, once mounted, are constantly used with tractors for performing various technological operations, including layout of seedbed and sowing. The efficiency of tractor track scarifiers is calculated using a mathematical model of agricultural implements. A performance indicator is total energy consumption that include the energy of the crop lost due to soil compaction by tractor wheels. The computational experiments show the efficiency of tractor track scarifiers for sowing. A power effect for a sowing machine used with a John Deere-9430 tractor is in the range of 8000-10000 MJ/ha.

The aim of this study was to analyse pulling and slipping parameters of tractors on the base of performed pulling tests and to develop general mathematic formulas suitable for the evaluation of pulling properties of tractors of different types in a roller testing station. For these measurements a JOHN DEERE 7820 tractor was used. Pulling characteristics of this tractor were measured in the roller testing station, which was equipped with a dynamometer VDU E270T-E150T. This paper presents results of such tests and enables to estimate with a good degree of accuracy and statistical significance final parameters of pulling properties of tractors. Final pulling parameters of tractors of different types can be estimated for arbitrary values of slippage. The derived relationships presented in this paper enable to evaluate pulling properties of tractors in a roller testing station with the same reliability as those defined for standard curves of slippage. The technical equipment of this roller testing station with four dynamometers enables to measure independently driving forces, slippage and speed of each wheel. In this testing station it is possible to evaluate pulling properties of tractors under changing load and to estimate pulling and slipping parameters of a concrete type of tractor.

Full textAbstract:
Agricultural tractors are robust and versatile machines, which must comply with the basic requirements of users under various conditions. The main requirements include economical and reliable operation and high performance. Fuel economy could be improved using multiple methods, for example a well trained operator, adequate farming conditions and optimal tire inflation. Tractor tires transmit engine power to the surface and as such they are crucial to tractor operation. In the first part of the field measurement, all tires were inflated to 180kPa, while in the second part of the field measurements the tire pressure was set to 75kPa in front tires and to 65 kPa in rear tires. The results of the field measurement of the John Deere 6920S tractor with different tire inflation shows that pull performance increased by 9.9% and wheel slip decreased by 9.7%.

Full textAbstract:
The main issue that has to be solved in the formation of modern systems for automatic driving of tractors is the issue of obtaining information about the current state of the machine-tractor unit relative to a given trajectory. In terms of its quality, this information should reflect the rather stringent requirements of agricultural production for the accuracy of trajectory control. Thus, to create devices for automatic driving of tractors, it is necessary to know the characteristics and properties of these machines as objects from the point of view of the theory of automatic control. When examining such machines, first of all, it is necessary to establish which parameter should be considered as input. With manual control, the feedback is closed visually on the right front wheel, more precisely at the point of contact of the wheel with the ground. The main goal of this work is to obtain equations connecting the input and output coordinates, as well as the input coordinate and coordinates of the middle of the front and rear axles of the tractor. It is also necessary to establish under what initial data a simplified equation can be used, taking into account only the kinematics of the tractor movement and not taking into account the elasticity of tires and deformation of the soil. For this, the problem is solved both taking into account the elasticity of tires and deformation of the soil, and without taking into account these factors. Frequency characteristics are compared, obtained using a simplified equation and taking into account the above factors at different speeds. During the research, the equations of motion of the tractor were obtained taking into account the deformation of pneumatic tires and soil. This equation allows you to study the movement of the tractor in the presence of external lateral forces. Such forces can be centrifugal forces when moving along a curved trajectory and forces from trailed and mounted implements on a tractor. The equation is valid for small steering angles of the tractor idler wheels. A simplified equation is obtained that does not take into account the deformation of tires and soil. This equation can roughly describe the movement of a tractor on solid ground, which is little deformed, at relatively low speeds. It is advisable to use this equation only at speeds not exceeding 1.7 m/s on dense ground. Both equations characterize the tractor as an object of regulation and allow the selection and design of an automatic steering system.

Subject of the study was the analysis of power parameters of three prototype of agricultural tractors John Deere model 6830, prepare to rapeseed oil as a fuel, operated since three years on different farmsteads. Energy parameters were tested of engine supplied with this oil (RO), then a control test was performed on diesel fuel (NO), according to the standard EN 590. Power of the tested tractors powered by rapeseed oil in relation to diesel fuel at 1700 rpm was about 7–15 % lower. Total consumption of fuel for both testing fuels oil was about 24–26 kg·h–1 at 1600–1900 rpm. Based on gathered tests results, it was found that unitary consumption of fuel was higher by about 11 % than in case of diesel fuel.

Abstract The objective of the paper is to analyse changes in the new farm tractor market in Poland and the annual income of farmers’ households generated in the same period. The studies covered the period from 2010 to 2020. The new farm tractors market was analysed with reference to the number of sold tractors, which was measured by the number of registrations. The paper considers quarterly seasonality of sale along with demand for selected producers and engine-power categories of new farm tractors sold in Poland. By “new tractors” the authors mean those registered for the first time in Poland and manufactured in the same or the preceding year. In 2010-2020, there were over 148,000 new farm tractors registered in Poland. The highest number of tractors sold was recorded in 2012, the lowest in 2016. Tractors from Western Europe, USA, and Japan predominate on the Polish market. Among new vehicles, the highest number registered in the investigated period constituted New Holland (23,780) tractors, followed by John Deere (19,453), Zetor (16,398), Deutz-Fahr (10,508), and Kubota (7,674). The total share of these producers in 2010-2020 amounted to approx. 58%. With regard to the engine-power categories in the analysed period, tractors with power of 37-73 kW and 74-132 kW (33.85%) constituted the largest proportion (49.07%). An increased interest in tractors with power below 36 kW was also observed from 2016 to 2020. Such vehicles accounted for 10% of all registrations. The general trend related to the volume of average annual income is not consistent with the trend of purchasing new farm tractors, while the highest number of registrations was recorded during the period in which inflation rates reached their highest values.

Abstract. In 2006, Cole et al. (2006) reported on tractor overturn-related injuries in Kentucky from a random sample of farmers that numbered 6,063 respondents. The highest number of people who experienced tractor overturns were operators 16 to 20 years old. In 2007, at a National Institute for Occupational Safety and Health (NIOSH) Tractor Safety Initiative meeting in Colorado, John Myers of NIOSH presented a map of the states with the highest overturn fatality rates: Tennessee, Kentucky, West Virginia, Ohio, Pennsylvania, and Illinois. Significantly, four of these states, including Kentucky, overlap the Appalachian region (Cole, 2007; Hard and Myers, 2001). In Kentucky, this region involves farming on slopes, as examined by Saman et al. (2012), who found a high-risk cluster of tractor overturns among ten Kentucky counties in the Appalachian region, with a 97% increased risk of overturn as compared to other Kentucky counties. In 1971, James Arndt of Deere & Company presented a 50-year review of rollover protective structures (ROPS) at a Society of Automotive Engineers (SAE) conference. Arndt (1971) estimated that, over the previous 50 years, 30,000 operators had been killed when crushed by tractor overturns in agriculture and construction work. Since then, ROPS have been recognized as an effective device to prevent death in the event of a tractor overturn (Reynolds and Groves, 2000). Nevertheless, the epidemic of tractor-related deaths has continued into the modern era, and the cost of ROPS has been found to be a significant barrier to retrofitting tractors that lack ROPS (Myers et al., 1998). To provide a low-cost alternative, NIOSH safety engineers have designed, tested, and provided instructions for building and fitting cost-effective ROPS (CROPS) onto pre-ROPS tractors (i.e., tractors built before 1968) (Hard et al., 2016). Keywords: NIOSH, ROPS, Tractor overturns, Tractor safety.

The present contribution deals with solves problem of research of testing device to monitor of hydrostatic pumps durability about dynamic loading under laboratory conditions. When carrying out the design of testing device are based on load characteristics of tractor hydraulic circuit, the individual characteristics of hydraulic components and performed calculations. Load characteristics on the tractors CASE IH Magnum 310, JOHN DEERE 8100, ZETOR FORTERRA 114 41 and Fendt 926 Vario were measured. Design of a hydraulic laboratory device is based on the need for testing new types of hydraulic pumps or various types of hydraulic fluids. When creating of hydraulic device we focused on testing hydraulic pumps used in agricultural and forestry tractors. Proportional pressure control valve is an active member of the hydraulic device, which provides change of a continuous control signal into relative pressure of operating fluid. The advantage of a designed hydraulic system is possibility of simulation of dynamic operating loading, which is obtained by measurement under real conditions, and thereby creates laboratory conditions as close to real conditions as possible. The laboratory device is constructed at the Department of Transport and Handling, Faculty of Engineering, Slovak University of Agriculture in Nitra.

The article provides an analysis of the park and the market structure of agricultural tractors of foreign brands, involved in the production of agricultural goods in Russian Federation and provision of agricultural organizations with tractors and combines to compare the currently existing rates with the regulations, listed by Ministry of Agriculture of Russian Federation to determine the proportion of foreign tractors as well as to determine the overall state of the market of agricultural tractors in Russia. To achieve this goal, the article presents the studies comparing the economic efficiency of the use in the production of agricultural tractors products of domestic and foreign brands on the example of tractors K-744 and Buhler-Versatile. The statistical data on volumes of production of agricultural tractors in the Russian Federation in general and divided by most common in rural areas brands of foreign and domestic tractors is shown. The data on the nomenclature of produced equipment from leading manufacturers of agricultural machinery of foreign brands, working in Russia, such as John Deere, New Holland, Claas, Agco and others is given. On the basis of the study it can be concluded that nowadays the majority of Russian agricultural producers prefer to buy foreign brands equipment. Despite the currency risks and the reduction of volume of the market of tractors in recent years, the demand for foreign brands of tractors from Russian farmers increased in comparison with the volumes of previous years. The increase in demand was observed in the segment of new and previously used tractors, produced outside the Russian Federation.

Full textAbstract:
The expediency of use of analogy of wheel and track movers interaction with the supporting surface is established. The research aim is to implement the possibility of simulation of power parameters of a track mover with rubber-covered caterpillars using the positions designed for movers of wheeled vehicles. It is suggested to determine an axial force in plane of contact area of track mover through the sum of products of normal responses and adhesion coefficients on slipping and idling sections of elements of contact area. The normal response in each section should be determined taking into account the variable diagram of specific normal responses. Without slipping of elements, a rectangular diagram is assumed; with full slipping, a triangle one with right angle on the rear part of contact area is assumed. A diagram is a trapezoidal in case of the intermediate slipping. It is recommended to calculate the adhesion coefficient of elements of contact area in the sliding section through the descending elliptical dependence as a function of the relative normal response on slipping section of contact area. The low value is equal to the static friction coefficient of elements without slipping, the high value is equal to the coefficient of sliding friction with full slipping. It is recommended to calculate adhesion coefficient of the idling section through the ascending elliptical dependence as a function of the relative normal response on slipping section of contact area. The low value is equal to zero without slipping, the high value is equal to the static friction coefficient in the transition to full slipping of extreme rear element. The calculated values of the axial force coefficient for track mover of John Deere 8300RT tractor with 1.91 radians of central angle of contact area are well coherent with the actual data of drawbar tests of John Deere 8310RT, 8335RT and 8360RT tractors carried out in the University of Nebraska-Lincoln. The proposed simulation algorithm of power parameters of track mover could be useful when choosing the rational traction modes of tractors operation in different operating conditions.

Contact Area Determination of Agricultural Tractor Wheel with SoilThe study is established based on contact area determination of tractor wheel. The significance of contact area in domain of wheel-soil interactions is considerable. Requirement for contact area estimations has prompted the researchers to determine numerous theoretical models. In this study, an experimental test was conducted inside a soil bin facility providing entirely reliable and controlled condition for the test. The soil bin included a carriage, a single wheel-tester and a frame. The utilized tire was a towed Good year 9.5L-14, 6 radial ply agricultural tractor tire which is used in John Deere tractors This test has the advantage of utilizing images taken of the contact areas and subsequently, using a plantimeter to obtain the values of contact area precisely. Test variables were the two most prominent and influential parameters i.e. tire inflation pressure in three levels (i.e. 100, 150, and 290 kPa) and vertical load applied on wheel in three levels (i.e. 1962, 2943, and 3924 N). The acquired results revealed that there is an increase in contact area induced by increase of vertical load and decrease of contact pressure. Contact area is shown to be highly influenced by vertical load in reduced tire inflation pressures.

Abstract. Five models for estimating fuel consumption for agricultural tractors with partial drawbar loads were compared. Data were collected from eight John Deere tractors, JD 7230R (e23), 7250R (e23), 7270R (e23), 7290R (e23), 8320R (16 speed), 7290R (IVT), 8345RT (IVT), 8370R (IVT), on the drawbar test track at the Nebraska Tractor Test Lab. The tractors were tested with seven load levels per speed at three different travel speeds as close as possible to 7.5, 10, and 13 km h-1. The IVT tractors were operated in auto mode, and the geared tractors were shifted up three gears and throttled back to the same travel speeds as obtained with the original gear (before shifting up) at maximum drawbar power. The seven loads were selected at 30%, 40%, 50%, 60%, 70%, 75%, and 80% of the drawbar pull at maximum power and rated engine speed at the selected travel speed. Model 1 (fuel consumption as a linear function of drawbar power on concrete), currently used in OECD Code 2, Section 4.4.8, resulted in a separate equation for each speed tested. When regression mean square errors were used for statistical comparison of the five fuel consumption models, model 5 (fuel consumption as a linear function of drawbar power and travel speed on concrete, and engine speed) was not significantly different from the model currently used in OECD Code 2, Section 4.4.8 (model 1, fuel consumption as a linear function of drawbar power on concrete, with separate equations specific to the three speeds tested). The simplest model (model 2), which used a single equation for fuel consumption as a linear function of drawbar power on concrete over the range of speeds tested, had significantly higher regression mean square errors compared to model 1 for half of the eight tractors tested. Model 5 (fuel consumption as a linear function of drawbar power and travel speed on concrete, and engine speed) was determined to be the best of the five models for estimating fuel consumption, with a single equation applicable over the range of speeds tested. Model 3 (fuel consumption as a linear function of drawbar power and travel speed on concrete) provided a statistically equivalent fuel consumption estimate to model 5 without the drawback of requiring an input value for engine speed. Keywords: Drawbar power, Engine speed, Fuel consumption, Model, Partial drawbar loads, Tractors, Travel speed.

To assess the effectiveness of corn cultivation technology based on the minimum tillage technology (Mini-till) and organic fertilizers, and compare it with the conventional technology including mouldboard ploughing, the authors conducted field studies in two farms of the Novokubansk district of the Krasnodar region. They analyzed economic efficiency indicators of seeders, the machine-tractor fleet, and the technology applied as a whole. The comparative analysis of economic indicators of an Optima TFmaxi direct seeder coupled with a John Deere 8310RT tractor used in the Mini-till technology and seeders used in the conventional technology have shown that using a direct seeder for seeding corn reduces mechanized work input by 0.15 man-h/ha (43%) and fuel consumption by 0.2 kg/ha (7%) as contrasted to the conventional one. However, specific operating costs are 3 times higher. The comparative analysis of the use of machinery and tractors in both technologies has shown that the Mini-till technology, as compared with the conventional one, uses less machinery (by 18 units, or 62%). But at the same time, the Mini-till technology uses 100% imported machinery, while the conventional one – only 24%. It has been established that the cost of resources for soil tillage in the Mini-till technology decreased as compared to the conventional one: mechanized work input – by 0.58 man-h/ha (46%), fuel consumption – by 9.1 kg/ha (18%), and specific operating costs – by 1227 rub./ha (17%). While using the Mini-till technology, the farmers recorded a grain corn yield of 10 t/ha, which is higher than that gathered with the conventional technology by 3 t/ha (43%). The obtained scientific and practical results prove the use of the Mini-till technology for economically sustainable agricultural enterprises of all ownership forms in the Southern Federal District of Russia.

Full textAbstract:
Due to the need to replace worn-out mechanization tools with more modern high-performance brands, the search for alternative technologies for growing potatoes is rather relevant. Tha author made a comparative analysis of the production efficiency of the ridge-band and ridge technologies of potato cultivation for CJSC Lenin State Farm in the Moscow Region. The area of potato cultivation of the “Pirol” variety was 400 hectares. With the ridge-band technology, the main and pre-sowing tillage was carried out by the MTZ 1025 and K744R1 tractors, while ZA1500 was used for fertilization. The PLN-5-35 plow and a KSS-9 cultivator were used as tillage tools. When shifting to the ridge technology of potato cultivation, alternative means of mechanization can be considered. Tractors MTZ 1025 and K744R1 are proposed to be replaced by John Deere 8295R. During autumn tillage, plowing was replaced by deep loosening, carried out by the Digger N Fert + COMPACT deep loosener with the simultaneous application of complex fertilizers. The GL 430 was chosen as the sowing machine instead of the energy-saturated Grimme VL20 KLZ machine. Potato harvesting is proposed to be carried out with a Ventor 4150 self-propelled harvester, which is less productive than the DR-1500, but more fuel efficient; moreover, it cuts the tops while harvesting. The proposed measures made it possible to reduce the production cost of one centner by 10.8% or by 33.5 rubles per 100 kg, increase profit by 16.0% and production profitability by 9.8%, thus reaching 43.7%. The practice of using new machines exemplified by this enterprise can be useful for other potato farms operating in the Non-Chernozem Zone of Russia.

Full textAbstract:
In the timber industry complex of Russia, medium-sized and small enterprises with a volume of timber harvesting up to 100 thousand cubic meters per year occupy a share of 48% in the total vol-ume. Most of these enterprises do not have the capacity to purchase new harvesters. An alternative to the new harvesters are the harvesters from the secondary market. Thus the study of changes in the technical condition of harvesters during their operation is an actual study for Russia. The data on the models, age, number of hours worked and the cost of harvesters that are offered on the secondary market was collected. 202 commercial offers were collected. In total there are 31 harvesters under 5 years of operation; 99 harvesters from 5 to 10 years of operation; 56 – from 10 to 15 years of operation; and 16 – older than 15 years of operation. There are 73 John Deere harvesters (including the outdated Timberjack models), with 8 tracked vehicles, 29 Ponsse harvesters; 49 Komatsu harvesters (including the out-dated Valmet models) with 4 harvesters based on a tracked excavator; 37 harvesters of different models made on the basis of tracked excavators and 18 harvesters of other models. Hypothetically assuming that there is a connection between the price of the harvester and its condition, correlations were analyzed between the price and the age of the harvester and between the price and the number of worked hours of the harvester. The relationship between the price and the age is described by power and exponential curves, with coefficients of determination of 0.56 and 0.54, respectively. Filtering data by power range (160-205 kW) and by model (three models were considered: John Deere 1270; Ponsse Ergo; Komatsu 931) did not lead to clear certainty about the form of regression, although it slightly increased the coefficient of determination. There are groups of factors that can influence the type of regression: the seller's factor, the repair factor, the operation factor, and the technical characteristics factor, but determining the degree of influence of these groups requires additional research. The dependence between the price and the number of worked hours is characterized by a very weak relation due to a large spread of data owing to incorrect values of the hours marked by sellers. General regression trends for harvesters are consistent with data for other types of tractors. But to determine unambiguity in regressions requires the accumulation of empirical data on the reliability of machinery and changes in their price over a number of years.

Using the technical characteristics of the PBS-10P trailed single-furrow plow and the results of tractor tests made by the Nebraska Tractor Test US laboratory, the value of towing tension of Case Magnum 340 (239 kW), New Holland Т9020 (213 kW), Challenger MT 835 (271 kW), John Deer 9120 (182 kW), Versatile 375 (226 kW), Versatile 400 (247 kW), New Holland Т9030 (310 kW) tractors and traction resistance of the PBS-10P plow at appropriate speeds were determined. The analytical dependencies of the traction force of the tractors and the traction resistance of the plow on the speed of movement are determined. The method of determining the rational composition of the arable unit is described, including: experimental determination of the plow traction at different tillage depth and speed; determination of the tractor force at the maximum traction power of the tractor; approximation of the obtained results in the form of empirical formulas; building graphical dependencies by empirical formulas and determining the optimal speed of the arable unit, which is used to calculate the productivity of the arable unit.

Full textAbstract:
The traffic-induced soil compaction in the field has gradually become an important constraint to sustainable agricultural development. A field experiment was conducted to acquire the stress transmitted caused by multiple passes with different types of tractors and to investigate the impact of these stresses on soil bulk density and crop growth. The experiment applied two tractors with different masses: LOVOL M904 (HC) and John Deer 280 (LC), and six different treatments of 0 (C0), 1 (C1), 3 (C3), 5 (C5), 7 (C7), and 9 (C9) tractor passes for each tractor. The results showed that at each number of passes, tractors with small axle-loads at 0–20 cm depth generated higher soil additional stress, while tractors with large axle-loads at 20–80 cm depth generated higher soil additional stress. In the 0–20 cm soil layer, when the number of continuous passes is less than 7 times, the passes of a small axle-load tractor lead to larger soil bulk density, and when the number of continuous passes is more than 7, the compaction of large axle-load tractor leads to larger soil bulk density. At depths of 20–80 cm, compaction by large axle-load tractors results in larger soil bulk density. In this study, different levels of tractor compaction inhibited key growth indicators of maize, resulting in yield reductions. The effect of different tractor load compaction on maize yield increased significantly with the number of compaction passes, with 1–5 tractor passes having no significant effect on yield and 7–9 passes producing greater yield reductions for HC. This study will provide a theoretical basis and technical support for the selection of agricultural machinery and reasonable tillage technology.

Full textAbstract:
In this study, a low-cost proposed platform for training dynamics (PPTD) is proposed based on operational amplifiers to understand the dynamics and variables of the agricultural tractor John Deere tractor model 4430 to gain autonomy and analyze the behavior of control algorithms proposed in real time by state feedback. The proposed platform uses commercial sensors and interacts with the Arduino Uno and/or Daq-6009 board from National Instruments. A mobile application (APP) was also developed for real-time monitoring of autonomous control signals, the local reference system, and physical and dynamic variables in the tractor; this platform can be used as a mobile alternative applied to a tractor in physically installed form. In the presented case, the PPTD was mounted on a John Deere tractor to test its behavior; moreover, it may be used on other tractor models similarly as established here. The established results of this platform were compared with models established in MATLAB, validating the proposal. All simulations and developments are shared through a web-link as open-source files so that anyone with basic knowledge of electronics and modeling of vehicles can reproduce the proposed platform.

Abstract The purpose of this study was to spatially identify the degree of mental fatigue of a farm tractor operator within the experimental field during grain sowing. In addition, to determine possible relationships between field space conditions and operator mental workload. The study was conducted on a John Deere 6210R tractor aggregated with a Horsch Pronto 4D seeder. The operator operated the tractor's on-board computer, the seeder's control computer, and a Trimble CFX-750 satellite navigation system. The mental workload of the tractor operator was monitored using a Muse 2 headband. The headband allows monitoring of brainwave activity, position and acceleration of the operator's head movements, and heart rate. It was found that the average value of attention was as high as 58% and was characteristic for seeding in the central part of the field (yellow) and in the north-western part of the field. The areas that required a much higher level of operator concentration (about 80%) were located in the southeastern part of the field and in the western part of the field. The applied research methodology allowed to generate spatial maps of the operator's level of mental engagement and thus to locate the value of mental engagement in a specific area of the field. On the basis of maps of spatial variation of the level of attention engagement by the operator, it is possible to generate information on which parts of the field on the farm will require special attention.

The work is aimed on possibilities of fuel consumption reduction via EHR system setting with the influence on tractor engine speed variation. During tractor utilization in agricultural applications fuel consumption is measured and evaluated. The main objective of this text is fuel consumption reduction verification. Firstly, article describes tractor engine parameters acquirement. Complete engine characteristic is obtained from laboratory experiments. This was essential step for lowest fuel consumption area detecting. Next, the principle of EHR system function is clarified. Then connection between complete engine characteristic and EHR system setting interaction is mentioned and the aim of field measurement is set. Another part is devoted to field measurement conditions and EHR system setting. This part is essential for the possibility of field measurement re-examination. Deep plowing with John Deere 6920S and Lemken Vari Diamant 10 was realized. The EHR various settings were examined and their effect on tractor engine speed variation was observed. The results show possibility of fuel consumption reduction. The properly chosen aggregation of tractor power and plough type with correct electro-hydraulic system setting brings fuel consumption reduction. This conclusion may be used for fuel savings in global scale for better economic utilization of tractor.

One of the promising directions for the development of crop production under present-day conditions is the im-provement of agricultural technologies of crop cultivation. Sowing is the most important technological operation; its quality largely determines the achievement of high yields. In this regard, the type of the seeding working body and the operating modes ofthe machine-tractor unitssignificantly affect the energy and agrotechnical characteristics of the sowing. As a result, it becomes necessary to substantiate the zonal parameters and operating modes of the sowing units taking into account the agronomic, technical and eco-nomic indices. The experiment was carried out on the farm of the OOO KKh “Zaytsev” in the Tyumentsevskiy District of the Altai Region. Based on the implementation of the field experiment using the planning of the experiment, a quantitative assessment of the effect of the speed opera-tional modes of the John Deere 730 and John Deere 1890 seeding units on the quality of spring wheat sowing, soil water regime and the yield was obtained. Each unit operat-ed at 4 levels of travel speeds. As a result, a technical and economic assessment of the compared sowing options was given. The results obtained will serve as the basis for substantiating the parameters and operating modes of the sowing units under operating conditions.

This paper deals with possible ways how to reduce consumption of Diesel oil under conditions of increased performance of tractor aggregates. In laboratory, complete characteristics of John Deere 8300 engine were measured on the power take-of shaft. The same tractor was thereafter used for field experiments with a seven-shares suspended turning plough. Measurements were carried out in the village Jeníčkova Lhota (county Tábor) on a field with loamy-sandy soil of 16.1% average moisture content. The specific volume density of dry soil was 1.48 g/cm3. The following engine parameters were measured: Diesel oil consumption, engine speed, wheel slippage, time interval required for passing through the measured distance and the depth and width of ploughing. Measured values were used for calculation of Diesel oil consumption (amount required for ploughing of 1 cu. m. and the area ploughed up for a unit of time). Tractor ploughed always with the full fuel tank. Measurements were carried out at 1680 – 1850 and 1900 – 2050 revolutions per minute. Obtained results indicate that with 1680 – 1850 rev./min. the average fuel consumption was 6.4 ml/cu. m while with 1900 – 2050 rev./min. it increased to 7.49 ml/cu. m. This means that the saving of fuel was a 17% and the increase in tractor performance 10.8%.

Abstract. A study has been conducted on the fuel consumption in direct sowing of wheat with a Horsch Avatar 6.16 SD direct seeder aggregated to a John Deere 7250 R tractor. The experimental field (29.53 ha) was sown with winter soft wheat (Silverio variety) at a sowing rate of 195 kg/ha. The data from the sowing unit were collected using the JD Link telematics system, downloaded from the system and imported and compiled in a database. Fuel consumption was analyzed in accordance with the operation mode, the idle mode and the transportion mode of the machine-tractor unit. It was found that the average fuel consumption in work mode (when the seeder was sowing) was 23.08 l/h, while in transportion mode the seeding unit consumed 16.55 l/h and while the unit was idling it consumed 4.30 l/h. The results also show that the seeding unit has travelled 63 km and consumed 185 L of diesel fuel at an average diesel consumption of 23.08 l/h.

This paper presents the results of an analysis of fuel consumption in the transport of technical roundwood of soft broadleaves from the felling site to a roadside landing using forwarders and tractor assemblies. The research was performed in various operating conditions in the area of FE "Banat" Pancevo. On the basis of the results of the analysis of variance, the data recorded in a variety of conditions were grouped. In addition, the dependence of fuel consumption on the average volume of tour was estimated. The results of the conducted analysis indicate that operating conditions significantly affect fuel consumption of the investigated vehicles. The elements of statistical analysis of the dependence of fuel consumption on the volume of load indicate that an increase in load causes increased fuel consumption per unit of production. Having in mind the results of the analysis of variance, unique norms of fuel consumption were adopted for practical purposes. The highest average consumption (1.21 L/m3) was achieved by a tractor assembly (Same Laser 130 tractor and Imako TP12 trailer with a Loglift 61F hydraulic crane), while significantly lower consumption was achieved by a John Deere 1210E forwarder (1.06 L/m3). In favourable operating conditions, consumption of the forwarder was about 0.9 L/m3.

Abstract Nine soil insecticides were applied at the fully labeled rate and a reduced rate at planting and first cultivation times at Concord, NE. The test plot was plant 8 May in a continuous corn field with a silty clay loam type. The experimental design was a randomized complete block with 4 replicates. Each treatment consisted of a single 40-ft-long row; rows were 30 inches apart. Infurrow treatments were applied by a John Deere tractor mounted unit at planting. All other treatments were applied in a 7-inch band by a Noble granular metering unit mounted on a hand-powered bicycle applicator equipped with incorporation tines on 9 May. Cultivation treatments were applied 5 Jun over the row followed immediately by a tractor mounted cultivator. Feeding damage was evaluated 17 Jul. Five roots were dug from each treatment row and rated by the Iowa 1-6 scale (1, no damage; 6, 3 or more nodes of roots completely destroyed). Rainfall was approximately 50% of normal for the period from 8 May to 17 Jul. Subsoil moisture rated short at time of planting.

Full textAbstract:
In recent years, requirements of certification bodies and forestry authorities for developed to felling in terms of the number of undergrowth per unit area are increased. To save the undergrowth and reducing the area of damage to the surface cover cutting areas it is most advisable to use wide-feller bunchers, for example, ЛП-19, МЛ-119, Timberjack 850, John Deere 753J, John Deere 759J, etc.. Number of undergrowth largely depends on the development plan of cutting areas development. Known technological schemes are reviewed and analyzed. When hauling packs of trees at one spur track of forest road feller-buncher moves with the rapid moves, which reduce the efficiency of the development of cutting areas as a whole. When hauling trees packs at two spur track of logging roads two fold increase in the length of spur tracks is needed, which greatly increases the effort required to perform logging operations and the cost of production? New technologies for development of cutting areas are presented. In this case, traffic schemes of track feller buncher and skidder are the same as the known technology of timber harvesting without undergrowth preservation. Saving undergrowth is provided by changing the sequence of execution of elements of technological operation for forming full-load for bundles of trees for skidding. Upon developing cutting areas on the proposed technologies processes of formation of full-load skidding bundles of trees is accompanied by a rise of trees above the ground from packs formed by feller bunchers, and transfer them to skidding trails. Performance of skidder is defined. When comparing all the considered schemes to develop cutting areas several factors must be considered: load factor of skidder, distance of idling, duration of stacking trees in the forming device, possible change in the rate of tractor stroke due to the different download.

ABSTRACT Soy harvest matches seasons with shortage of dry matter supply for ruminant feeding in most Brazilian soy-growing areas. Agricultural machinery-producing companies must have market perception, observing new opportunities and developing equipment to meet costumers’ needs. This paper aims to design, build, and test a device to collect soybean crop residues from the combine cleaning mechanism, consisting mainly of vegetable straw (chaff), and the other plant parts (stems) remain being deposited onto the ground. For equipment designing, we made use of the architectural design methodology proposed in the reference model for the agricultural machinery development process. The equipment was designed and built following the proposed methodology, then installed and put into operation in a John Deere 1165 combine. After initial testing and few adjustments, the device showed satisfactory chaff-collecting performance. The equipment consists of a screw conveyor assembled transversely to the combine and a centrifugal fan assembled on the side. The collected chaff is dumped into a trailer towed by tractor.

Abstract Efficacy of selected insecticides was evaluated for TT control and for effects on growth and yield of Okrun runner type peanut in Chickasha, Oklahoma. Peanuts were planted on 36-inch rows on 16 May. Granular insecticides were applied into the seed furrow (IF) at planting with a tractor-mounted John Deere granular applicator. A RCB experimental design was used with 4 replicates; plots were 4 rows wide by 50 ft long. Treatments were evaluated by comparing: plant stand counts per l/1000th of an acre and injury ratings based on a 0 to 6 scale where 0 = no thripinjured leaf and 6 = 100 percent injured leaves. In addition, thrips control was evaluated by collecting 5 unopened quadrifoliate leaves per plot on 1 May, 6 Jun, 13 Jun, 20 Jun and 28 Jun. Unopened leaves were placed in vials of alcohol and returned to the laboratory where adult and larval thrips were separated and counted under a dissecting microscope. Yields were based on digging, combining, drying and weighing peanuts from 2 rows of each plot. Data were analyzed using ANOVA and LSD procedures.

Abstract Seven insecticides were applied at the fully labeled rate and a reduced rate at planting and first cultivation times at Concord, Nebr. The test plot was planted 8 May in a continuous corn field with a silty clay loam type. The experimental design was a randomized complete block with 4 replicates. Each treatment consisted of a single 50 m long row; rows were 11.8 cm apart. Infurrow granular treatments were applied by a John Deere Tractor mounted unit at planting. Granular formulations were applied in a 2.75 cm band by a Noble granular metering unit mounted on a hand-powered bicycle applicator equipped with incorporation tines on 11 May. Furadan 4 F was applied over the row in a 2.75 cm band and basally, both at cultivation time with a C02 backpack sprayer at 25 psi, approximately 142 liters/hectare total volume. Cultivation treatments were applied 12 Jun over the row followed immediately by a tractor-mounted cultivator. No phytotoxicity was observed. Stand counts were not significantly different. Feeding damage was evaluated 23 and 23 Jul. Five roots were dug from each treatment row and rated by the Iowa 1-6 scale (1, no damage; 6, 3 or more nodes of roots completely destroyed). Rainfall was near normal for the period from 8 May to 24 Jul, with no rainfall event more than 2 inches in any 24 h period. Subsoil moisture rated short at time of planting.

Abstract Planting-time soil insecticides were evaluated for wireworm control in a field that required replanting. Wireworm feeding had reduced the stand in a 10-acre sandy-loam field from 25,000 to 6,000 plants/acre. Field cultivating removed the existing stand and prepared the seedbed for replanting. The experimental design was a randomized complete block with 4 replications. Treatments were applied to single, 50-ft length rows with 30-inch row spacing. Granular insecticide formulations were applied with modified Noble metering units that had been laboratorycalibrated to accurately deliver material at a tractor speed of 4 mph. The applicators were mounted on a 4-row John Deere Max-Emerge 7100 integral planter. Each row was constantly monitored to insure that insecticide was being correctly applied at all times. Drag chains were used for incorporation. Seed treatments were machine planted with each seed treatment assigned to its own seed hopper. Following corn emergence, stand counts were taken from 1/1000 acre/ treatment and the seeds/seedlings were carefully extracted from two 1-m sections of row and inspected for wireworm feeding damage. The untreated check rows revealed no feeding damage and the plot was not evaluated further.

Abstract ‘Pioneer 3165’ field corn was planted on 7 Apr in loessial silt loam (Gigger-Gilbert complex) at the Macon Ridge branch of the LSU Northeast Research Station. Granular insecticides were applied at planting using a 2-row John Deere Model 71 Flexi-Planter, modified to carry 1-pt jars of insecticide. Jars were inverted above funnels connected by flexible delivery tubes to either a 7-inch band or an in-furrow applicator. The diameter of a single central hole in the lid of each jar, in combination with tractor speed, determined the rate of insecticide flow. Banded insecticides were applied in front of the press wheel and further incorporated by a drag cahin attached to the rear of the planter. A randomized complete block design with 4 replications was used, and each treatment consisted of two 40-ft rows spaced 36 inches apart. Treatments were evaluated 6 May by counting the number of chinch bugs/20 plants, the number of plants infested with nymphs, and stand counts/40 ft of row. After maturity the corn was harvested and data collected on lb of shelled corn per 40 ft of row.
