MAINTENANCE/SERVICE
Traction Drive: Neutral Set-Up Procedure
This procedure should be performed only after the
nine preceding checks and adjustments have
failed to solve the neutral lock/steering problem.
This procedure will eliminate machine movement
in neutral and will improve neutral locking ability.
CAUTION: Use jack-stands with a
minimum capacity of 3 tons (2720 kg)
to provide adequate support for
machine.
DANGER: Never attempt neutral set-
up procedure without raising front
wheels off the ground so they are
free to turn. Failure to raise front
wheels will result in machine runaway, causing
severe personal injury or death.
1. Detach header and remove hay conditioner
forming shields from under tractor.
2. Raise front of machine high enough to allow
both wheels to turn freely and support with jack-
stands. See "Jacking Procedure" under Wheel
& Tire Maintenance in this section.
3. Start engine and idle at approximately 1400 -
1500 RPM.
4. Set controls as follows:
• Ground speed lever in neutral.
• Steering wheel locked.
• Park brake disengaged.
5. Loosen bolts (A), allowing the bolts to slide
freely in slots.
NOTE THE FOLLOWING:
• Front pintle arm (B) controls the right wheel and
rear pintle arm (C) controls the left wheel.
• Moving the pintle arms towards the front causes
the wheels to turn forward. Moving the pintle
arms rearward causes the wheels to turn in
reverse.
• The pintle arms are located in neutral when
they are between the forward and reverse
positions. The neutral lock adjustment bolts (D)
are used to position the pintle arms in the
neutral range.
• Each neutral lock adjustment bolt has a jam nut
(E). Always hold bolt (D) with a second wrench
when loosening or tightening jam nut (E) so
pintle arm positions are not lost.
6. Loosen jam nuts on bolts (D) and turn bolts in
and out to find the neutral position of each pintle
arm, that is, the position where drive wheels are
not turning. Finger tighten bolts (D) against
pintle arms.
