C. DIFFERENTIAL LOCK
When resistance to the right and left tires is different
due to ground conditions or type of work, the wheel
with less resistance slips and prevents the tractor
moving ahead.
To compensate for this, the differential lock restricts
the differential action and causes both rear axles to
rotate as a unit.
When the differential lock pedal is stepped on, it causes
the differential lock fork (10) and differential lock clutch
(7) are moved toward the spiral bevel gear (1).
The differential lock clutch (7) is engaged with the teeth
of the differential case (4) to cause the differential case
(4) and differential lock clutch (7) to rotate as a unit.
Therefore, the differential pinions (3) are prevented from
rotating on their axes so that they move around the
center of the differential side gears (5) as in the case of
the tractor going straight ahead.
Thus, the rotation of the spiral bevel pinion is transmit-
ted to the both rear axles evenly.
When the drive wheels regain equal traction, the lock
will disengage automatically by the force of differential
lock pedal return spring.
