DECELERATOR PEDAL
At the lower front of the right console is a
mechanically actuated decelerator pedal, 1,
which can be used to reduce engine speed when
turning or while shifting. When fully depressed,
engine speed will drop to a preset level. If the
pedal is not fully depressed, engine speed will be
reduced proportionally. When the pedal is
released, engine speed will return to the
previous throttle setting.
IMPORTANT: Do not release the decelerator
before completing the turn. If the transmission is
in a high gear, the tractor will accelerate quickly,
reducing the time to correct tractor direction.
The factory presets the decelerator pedal to
reduce the engine speed to 1400 RPM. See
Section 3 of this manual for adjustment
procedures.

DIFFERENTIAL LOCK
The tractor may be factory equipped with an
electronically controlled front axle differential
lock. This will provide additional tractive effort on
hillsides or wet ground. The switch, 1, is a three-
position momentary switch located on the right
console. To activate, push the front side of the
switch. An indicator light will illuminate on the
warning light bar. The differential lock can be
locked when the tractor is moving or stopped.
IMPORTANT: Do not engage the lock when the
tractor wheels are spinning or when the wheels
are turning at different speeds, such as an end of
the field turn. Drivetrain damage may result.
To disengage the differential lock, push the rear
of the switch down until the indicator light on the
warning light bar turns off. Depressing the brake
pedal will also disengage the differential lock.
Disengage the differential lock when not
required, such as during high speeds and road
travel, turning and parking, or when additional
traction is not needed.
CAUTION: DO NOT USE THE DIFFERENTIAL
LOCK WHEN DRIVING THE TRACTOR ON
ROADS OR STEERING MAY BE IMPAIRED.
