Pressure on the Soil of the Front Wheels of Tractors with Different Wheel Formulas

An increase in the power of wheeled tractors led to an increase in their mass and the mass of machine tools aggregated with them, which led to negative anthropogenic impacts on the soil, especially of tractors with a wheel formula of 3K2. Experiments have shown that the pressure created by the front wheel on the root layer on the soil of the TTZ-811 tractor with the 3K2 wheel formula is on average 4.5-9.5 % higher than that of the TTZ-1033 tractor with the 4K2 wheel formula. Reducing the sealing effect of the front wheels on the soil is possible by replacing the tractor with the wheel formula 3K2 with a tractor with the wheel formula 4K2, as well as by reducing the air pressure in the tire.
