ADJUSTING THE STEERING DAMPNERS
6.8
The steering dampner adjustment can be made to
increase or decrease the dampening affect for smooth,
precise steering control. There are three locations on the
steering control levers that allow the operator to adjust the
dampening affect of the steering control based on cutting
conditions.
Top Mounting Location (Figure 6-9).

highest dampening affect on the steering controls.

ELECTRIC CLUTCH ADJUSTMENT
6.9
The electric clutch serves two functions in the operation of
the mower. In addition to starting and stopping the power
flow to the cutter blades, the clutch also acts as a brake to
assist in stopping blade rotation when the PTO is switched
off or the operator presence circuit is interrupted.
When the clutch is disengaged, the air gap between
the armature and rotor must be adjusted to fifteen
thousandths of an inch, 0.015, for proper operation. The
airgap adjustment is made at three bolts on the clutch.
There are three inspection windows, one next to each
adjusting bolt. See Figure 6-10.

Locate the inspection windows on the clutch.
1.
Place a 0.015 feeler gauge in the slot between the

rotor and the armature.
Tighten or loosen the adjusting bolt as needed to

acheive the 0.015 inch airgap. See Figure 6-11.
Perform this operation at all three inspection
windows.

Clutch Air Gap Adjustment

This adjustment should be done every 500 hours of
operation or annually, whichever comes first. In cases
where the machine is heavily used, airgap settings should
be checked more often.
If the air gap is too narrow, the clutch armature may drag
when disengaged, resulting in premature failure.
If the air gap is too wide, the clutch may be slow to
engage as the magnet must pull the armature in from a
greater distance.
