TRACTOR OPERATION
E221 E222 E223
DIFFERENTIAL LOCK
Push the switch to engage the lock; the
switch will return in the initial position
after releasing.
Engagement of the differential lock is
indicated by the lighting symbol in the
switch.
When depressing the brake pedals, the
differential lock will disengage automati-
cally.
Do not use the differential lock
when driving in a curve.
FRONT DRIVING AXLE CONTROL
In the basic position, the front driving
axle is engaged.
Engagement of the front driving axle is
signalled by the lighting symbol in the
switch.
Disengagement is made with the switch
that is situated on the dashboard.
a - Front driving axle disengaged
b - Front driving axle engaged
With the stopped tractor (braked tractor,
stopped engine, ignition key in “0” posi-
tion), the front driving axle is engaged.
At sudden air pressure drop in
the tractor air pressure system,
the front driving axle is automati-
cally engaged.
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.
