DRIVING WITH THE FRONT DRIVING
AXLE ENGAGED
Use the front driving axle when rear
wheels are slipping to increase the
tractor traction force. On the road and
on hard ground the driving with the front driving
axle engaged is permissible within maximum
speed of 15 km/h (the driving with the front
driving axle engaged on the road and on hard
ground causes excessive wear of front tires).
Permanent engagement of front driving
axle is permitted if the agriculture ma-
chine or implement is attached to front of
the tractor. This condition is specified in
Operator's Manual of each particular
machine. Maximum permitted speed of
the tractor combination is 15 km/h in that
case.
