Abstract: Traction features of the tractor depend on the dynamic rates of the engine and transmission parameters. The traction features of the tractor depend greatly on the driving wheel exploitation characteristics, the physical-mechanical properties of the soil, and on the interaction of the driving wheels and the soil. By reference to the tests it was estimated that in the soil, if tractor wheels transmit driving force, they certainly slip. To reach maximum efficiency in production works, tractors are loaded by as high drawbar pull as possible. The consequence of it, quite often, is that the slippage of the driving wheels grows to the limit that is not allowed. There are various ways to reduce slippage. One way is to increase the contact area between the tires and the supporting surface. This is achieved by increasing the vertical wheel load and decreasing the pressure in the tires. There will be obtained the dependences between slippage and drawbar pull on various field conditions in this paper. When the tractor works by changing the drawbar pull, the distribution of vertical load on the front and rear axles changes, and it is difficult to set. This problem will be discussed in this article, too
