Estimation of ballasting tractors 5-6 traction classes

To increase productivity in agricultural production, combined wide-grip machines are being created, aggregated with tractors of traction classes from 5 and higher. In addition, according to agrotechnical requirements, the pressure of the mover on the soil should be minimal, as well as the number of passes over the surface of the field. These contradictions can be solved by ballasting of tractors, which allows using engine power to increase tractive effort. Ballasting affects energy saturation. Increased energy saturation with appropriate ballasting makes it possible to compose machine-tractor units (MTU) according to a more accurate ratio of the tractor pulling force and the unit's pulling resistance. The most in demand in modern agriculture are tractors of 5-6 traction classes produced by domestic and foreign tractor-building plants with an internal combustion engine with a capacity of 220-320 kW and an operating weight of 115-150 kN. The article contains a two-way analysis of variance, which makes it possible to determine the greatest influence on the ballasting of a tractor. A diagram is constructed that gives an idea of which of the studied brands of tractors can be recommended for performing agricultural operations, taking into account ballasting and compliance with agrotechnical requirements.
