Differential Lock Pedal - New Holland Boomer 45 Operator's Manual

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 turning 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 serious injury.
WARNING
Loss of control hazard!
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.
The differential lock pedal is located on the left-hand foot
platform on HST models (1) and on the right-hand foot
platform on mechanical transmission models (2). To ob-
tain additional traction on wet or loose soil, use the differ-
ential lock.
When the differential lock pedal is depressed, both fi-
nal drive pinion gear shafts lock together, preventing 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 opposite wheel.
To operate the differential lock, depress, and hold the
pedal down until the lock engages. 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 dis-
engage the differential lock.
NOTE: In some instances, the lock may remain engaged
after the operator releases the pedal. This can occur if
one rear wheel is turning at a faster speed than the other
is. 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.
