Note. Change of load depending on speed is used in cases, when tires are not loaded for
prolonged time at high torque. During field works and under other conditions of prolonged
operation at high torque, values that correspond to speed of 30 km/h are used.
IMPORTANT! For tractors with PTO correct combination of front and rear tires should be used.
Correct combination of front and rear tires provides maximum operation qualities of the tractor,
increases tires’ life and reduces wear of power gear components. The use of worn out and new
tires, or tires with different diameter or rolling radius may result in excessive wear of tires. Address
your dealer for mounting tires of different dimensions.
For normal tractor operation bring pressure in tires in accordance with given-below table. When
operating frontal loader set maximum pressure given for front tires.
To achieve optimum operation parameters of the tractor, set pressure in tires in the range from
minimum to maximum in compliance with actual loads on tires.
Allowable loads on tires (kg) depending on inside pressure in tires (kPa)
With double wheels, air pressure in tires of outer wheels should be 1.20... 1.25 times less than
in inner ones ( to avoid early failure of FDA pivot bearings).
Liquid ballast
Tires are filled with liquid ballast only when traction of wheels with soil is not sufficient under
unfavorable conditions (over humid soil, etc.).
NOTE: It is not recommended to ballast front tires, as this makes tractor steering worse.
