Change of rated load on tire depending on the speed is applied in cases when the
tire is not operated for a long time with high torque. Values corresponding to the speed of
30 km/h shall be applied for field work and other conditions of long-term operation with
high torque.
4.10.9 Application of rear axle differential lock
The tractor rear axle differential provides means for rotation of driving wheels with
different frequencies, which is necessary for moving along a curvilinear path and on a
rough road, when right and left rear driving wheels travel over different distance for the
same time.
Disadvantage of the differential is that it dispenses the torque on the wheels in in-
verse proportion to tire grip on the road. If one wheel lands on the area with small adhe-
sion coefficient (for example, on ice), the wheel will slide and rotate with high frequency,
while the other wheel will rotate slowly. Tractor will move at a very low speed. To exclude
this disadvantage, the differential lock (excluding from the operation) is provided in positive
mode.
Tractor operation with the differential locked on a firm and dry surface results in in-
creased loads of transmission and chassis components, and impedes maneuvering.
THE TRACTOR MUST NOT BE OPERATED WITH REAR AXLE DIFFERENTIAL
LOCK ENGAGED WHEN THE DRIVING SPEED EXCEEDS 13 KM/H!
THE TRACTOR MUST NOT BE OPERATED ON HARD-SURFACE ROADS WITH
REAR AXLE DIFFERENTIAL LOCK CONSTANTLY ENGAGED!
