Electric PTO Clutch
Adjustment
Check the PTO clutch adjustment after 250 hours of
operation. Also perform the following procedure if the
clutch is slipping or will not engage.
1. Remove key from ignition switch and disconnect
spark plug wires to prevent the possibility of
accidental starting while the PTO is being adjusted.
2. See Figure 20. Note the position of the 3 adjustment
windows (A) in the side of the brake plate and the
nylock adjustment nuts (B).
3. Insert a .012” feeler gauge through each window,
positioning the gauge between the rotor face and the
armature face as shown in Figure 20.
4. Alternately tighten the adjustment nuts (B, Figure 19)
until the rotor face and armature face just contacts the
gauge.
5. Check the windows for an equal amount of tension
when the gauge is inserted and removed, and make
any necessary adjustments by tightening or loosening
the adjustment nuts.
NOTE: The actual air gap between the rotor and
armature may vary even after performing the adjustment
procedure. This is due to dimensional variations on
component parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower
blades and mower drive belt should come to a
complete stop within five seconds after the electric
PTO switch is turned off (see MOWER BLADE
BRAKE STOPPING CHECK, Page 6).
