MAINTENANCE/SERVICE
Traction Drive: Neutral Lock and
Steering Checks
DANGER: To prevent machine run-
away:
• STOP ENGINE before adjusting steering
linkage or neutral interlock.
• Never rewire or misadjust neutral interlock
so engine can be started with controls out
of neutral.
• Never start engine by shorting across
starter terminals. Machine will start with
drive engaged and move if normal starting
circuitry is bypassed.
• Start engine only from operator's seat.
Never try to start engine with someone
under or near machine.
• Refer to proper start-up procedure in
Operation section.
A properly functioning system should operate as
follows:
• The starter should engage ONLY when the
ground speed lever is in neutral, the steering
wheel is locked, and the header drive switch is
in the off position.
• Under these conditions, the machine should
not move after engine start-up.
If either of the above does not hold true, perform
the following nine checks. Adjustments, if required
are described following each check point. A
troubleshooting section follows the checklist.
DANGER: To avoid severe personal
injury or death caused by machine
runaway, shut off engine and
remove key before performing any
of the following checks and/or
adjustments.
1. Neutral Start Switch: Check that electrical
connections are good at neutral start switch (A).
With controls in start-up position as described
above, plunger of switch must be compressed.
Adjust switch support if required. Do not over-
adjust switch support, as this will prevent pintle
arms from locking as described in Check # 3.
2. Header Drive Belt Switch: Check that electrical
connections are good at header drive belt
switch (B). With controls in start-up position,
(belt disengaged), plunger of switch must be
compressed. Adjust switch support if required.
