b. Operation Principle of the Differential Gear
If differential pedal (1) is pressed down, the differential
rod connected to the pedal gets pulled forward and
differential mounting fork shaft (3) gets rotated. Since
differential mounting fork (4) is moved to the left and
connected with the dog of differential mounting shift
(5) through the dog’s groove of differential gear as-
sembly (10), while differential function is not operated,
along with 13 gear shafts (left and right) (6) revolved
together. If differential lock is operated, 13 gear shafts
both left and right rotate at the same speed and trans-
mit the same capacity of power to the rear axle.

CAUTION
• When running while the differential
lock is operated, do not turn the steer-
ing wheel to toe left or right.
• If the steering wheel is turned to the
left or right, the differential lock may
be damaged because the rotation
speed differs between the left and the
right wheel.
