Differential lock pedal
WARNING
Steering is difficult with the differential lock
engaged. An accident could result.
During field operation, use the differential lock
for traction improvement but release for turn-
ing at row end. Do not drive at high speeds or
on roads with the differential lock engaged.
Failure to comply could result in death or se-
rious injury.
W0292A
The differential lock pedal is located on the left-hand foot
platform
(1) on HST models and on the right-hand foot
platform (2) on gear models. The differential lock is used
to obtain additional traction in wet or loose soil.
When the differential lock pedal is depressed, both fi-
nal drive pinion gear shafts are locked together, prevent-
ing one wheel from rotating independently of the other.
Whenever one wheel begins to slip in wet or loose soil,
use the lock to obtain additional traction from the oppo-
site wheel.
To operate the differential lock, depress and hold the
pedal down until the lock is positively engaged. It is best
to engage the lock while the wheels are turning slowly to
minimize shock loads to the driveline. If a wheel spins at
high speed, such as on ice, reduce engine speed to idle
before engaging the lock or damage may result. Release
the pedal to disengage the differential lock.
NOTE: In some instances, the lock may remain engaged
after the pedal is released. This can occur if one rear
wheel is turning at a faster speed than the other. The lock
can be disengaged in one of two ways if this occurs:
• Decrease the drawbar pull by raising or disengaging the
implement so that neither wheel tends to slip.
• Depress the clutch pedal and rapidly apply and release
a light braking load to the wheel with less traction.
