Résumé :
Tractors are the main machines in agricultural production processes. Agricultural tractors commonly employ a four-wheel drive transmission. To reach maximum efficiency in production works, tractors are loaded by as high thrust as possible. The consequence of it, quite often, is that the slippage of driving wheels grows to the limit that is not allowed. To reduce the slippage, various ways are pointed out in terramechanics. One way is to increase the tractor’s weight by adding ballast. The other way is to increase the contact area between tires and the supporting surface. The slippage can be al

The article presents an analytical approach to the implementation of ballasting and dual tires using of agricultural wheeled tractors, which is based on the unconditional fulfilment of agro-ecological standards of tires soil interaction. The necessity of harmonizing the indicators of the position of the centre of gravity of the tractor, the footprint area of the front and rear tires ratio, as well as their load capacity is shown. The need to use equal flotation in tractor’s tires during single and double use has been proven, which determines the need to maintain the position of the centre of g

Résumé :
In agriculture, machines engaged in various agrotechnical activities and operations have different impacts on the soil. The effect of mechanization is primarily reflected in two indicators: soil density and hardness. At the same time, considering the direct dependence of tractive resistance on soil hardness in processing machines and sprayers, we studied subsequent changes in the soil in the path of wheels affected by the soil after the passage of four-wheeled and three-wheeled tractors. We also examined various atmospheric pressures in the tractor’s tires and the impact of different types of

The track surfaces of tires 15.5-38, 16.9R38, 420/85R38 and 18.4R38 are compared on a rigid base. The track surfaces for hard base and maximum pressure of tires on soil, soil density and tire tread depth were determined in experimental studies. When choosing tires, their average qav and maximum q max pressures on soil were determined.

Résumé :
The transmission of mechanical front-wheel drive tractors normally has a front axle lead ratio, which is equal to 1.5…2.5%. Naturally, when ballast masses are added to the tractor or when inflation pressure in the tires is reduced, distortion of the tires is inevitable, which changes the lead of the front wheels. In this paper, we present the impact of tire inflation pressures on the lead front drive wheels and movement resistance force when the tractor travelled with a front drive axle enabled and was engine braking with the fuel supply off.

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.

Edward Bouverie Pusey once towered over nineteenth-century British theology, but he has now fallen into almost entire insignificance. However, analysis of this decline (Chapter 1) leads to a reassessment. His development—especially his complicated relationship with pre-Tractarian High Church Anglicanism—shows a deep criticism of post-Enlightenment intellectual trends, from his early years through his association with the Oxford Movement and the Tracts for the Times, to the end of his life (Chapter 2). This criticism led him to the patristic use of allegory, both as a biblical hermeneutic and a

The tractor under draft causes slippage of the driving wheels, which negatively affects the soil structure and soil function, influences the plant growth and yield. Tires compress and compact the surface layer, erode the soil, and reduce liveliness of plant roots. Driving of tractors is unavoidable but may be more friendly to the environment. The aim of the research was to establish the dependence of the tire contact area and tractor slip on the plant yield, maintaining a constant draft.

Résumé :
Nowadays, economical, technical and ergonomic factors have a great importance on the design of the agricultural tractors. The paper illustrates the use and the management of heterogeneous product information (manual measurements and drafts, 2D drawings, technical documentation, photos), advanced CAD modeling tools and digital human models, for the redesign and the ergonomic optimization of an agricultural tractor’s driver cab. The project development has been organized using a top–down approach in a collaborative environment. At first, a manual measurement with gauges allowed to realize a tech

Résumé :
The Hohenheim Tire Model (HTM) was developed and validated at the University of Hohenheim. It simulates the specific behavior of large-volume agricultural tires and is used in conjunction with multi-body models of tractors and other agricultural machines. Special focus is placed on driving dynamics and comfort. Currently the HTM is being expanded for implementation on soft soils. Therefor the soil's shear response using Bevameter tests and the relationship traction-wheel slip using a single wheel tester are investigated. In field tests, the effect of shear rate on soil mechanical parameters wa

Résumé :
Everyone wants to be happy. Over the ages, tracts of the ancient moral philosophers – Plato, Aristotle, Confucius – have probed the question of happiness. The stirring words in the preamble to the Declaration of Independence that established ‘Life, Liberty and the pursuit of Happiness’ as ‘unalienable Rights’ served as the inspiration that launched a nation, the United States of America. Yet, more than 240 years later, the relationship between government’s objectives and human happiness is not straightforward, even over the matters of whether it can and should be a government aim. We approach
