Abstract:
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.

Abstract:
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.

Abstract:
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:
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.

Abstract:
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.

Abstract:
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%.

Abstract The John Deere 8000 series track (8000T) tractors, introduced in June 1997 represent a significant change in steering system compared to previous John Deere tire tractor models. John Deere 8000 series track tractors are the first tractors in North America using “steer-by-wire” philosophy. The new steering system uses an electric signal to control the electro-hydraulic hydro-static system. The steering system provides performance improvements in several areas for unmatched operator convenience and control. This paper describes the steering system configuration, components, operation, characteristics and some of the engineering considerations dealt with in the development process. The overall steering system truly represents a mechatronic design.

Abstract:
The John Deere 7000 TEN series tractors represent a significant change in the transmission system compared to previous John Deere tractor models in this category. John Deere 7710 and 7810 series tractors are the first of the 7000 TEN series tractors offering an infinitely variable transmission (IVT). These tractors provide infinite vehicle speeds in the forward mode from 50 meters/hr to 40 km/hr or an optional 50 km/hr. Reverse mode provides infinite vehicle speeds from 50 meters/hr to 17 km/hr. The IVT provides performance improvements in several areas for unmatched operator convenience and control. The new IVT uses an electric signal to control the electro-hydraulic hydrostatic system with mechanical power train. The IVT represents a hydro-mechanical transmission system using electronics, hydraulics and mechanical systems’ integration to achieve the required performance. This paper describes the IVT system configuration, components, operation, characteristics and some of the engineering considerations dealt with in the development process. The overall IVT system truly represents a “drive-by-wire” mechatronic design.

Abstract:
This paper develops two analytical models that describe the yaw dynamics of a farm tractor and can be used to design or improve steering control algorithms for the tractor. These models are verified against empirical data. The particular dynamics described are the motions from steering angle to yaw rate. A John Deere 8420 tractor, outfitted with inertial sensors and controlled through a PC-104 form factor computer, was used for experimental validation. Conditions including different implements at varying depths, as would normally be found on a farm, were tested. This paper presents the development of the analytical models, validates them against empirical data, and gives trends on how the model parameters change for different configurations.

The paper presents depreciation calculation of new MTZ 952 tractor and John Deere T 550 combine. Two time (linear and degressive) and functional methods for depreciation calculation were applied. After exploitation period of use, by calculating the annual depreciation of fixed assets, farmers can more easily plan the purchase of new machines. Also, the results of depreciation costs help farmers in making rational decisions on purchase of new machinery, or possible services engagement machines of other farmers. Taking into account costs of depreciation, prices of services provided by mechanization can be realistically determined, so based on that, farmers will choose what is more profitable.
