Theoretical study of energy properties of tractors

In the article the system of forces acting on the tractor is analysed and on the basis of the equation of statistics the driving force of the tractor is determined, which creates useful traction force and overcomes the forces of resistance to tractor movement. The basic measures provided for reduction of slipping and improvement of traction properties of wheeled tractors taking into account working conditions are stated. Qualitative representation of driving force and its limits are investigated, that, allows to carry out quantitative definition of maximum tractor traction force, necessary for application in real production conditions for the purpose of increase of productivity of agricultural aggregates.
