MECHANICALLY CONTROLLED DIFFERENTIAL LOCK
DIFFERENTIAL LOCK CONTROL -- fig. 70
The differential allows the drive wheels to rotate at
different speeds when the tractor is turning.
The differential has a locking device, controlled by a
foot pedal (1) fig. 72. It is advisable to lock the
differential in the following situations:
-- in ploughed fields, to prevent the wheel which is
out of the furrow from slipping.
-- if one of the drive wheels is on uneven, muddy or
slippy ground, and tends to skid.
To lock the differential, reduce tractor speed and
press pedal (1) fig. 72. The differential will remain
locked.
Press one of the brake pedals (1) to release the lock
fig. 73.
CAUTION
Do not keep the differential locked unnecessarily as
this wastes power and can cause damaging stresses
in the transmission system, tyre wear and steering
problems.
