6.8 ELECTRIC CLUTCH ADJUSTMENT

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.
