Adjust Blade Height

Level and pitch the mower with the height

adjusters on each deck lift bracket

(Figure 25).

Loosen the jam nut on the deck lift

bracket bolt about 1/4 turn to reduce

clamp load on the height adjusters.

Loosen the jam nut on the deck adjuster

bolt and then turn the bolt clockwise to

raise the deck or counterclockwise to

lower the deck. Tighten both jam nuts.

CLUTCH ADJUSTMENT

If clutch fails to engage or disengage properly

or begins to make abnormal noise, check the

air gap adjustment at the three inspection

slots.

To check:

1. Stop engine, remove key and wait for all

hot parts to cool.

2. Measure the air gap between the

armature and the rotor.

Minimum: A .016" feeler gauge should

slide between armature and rotor with

slight contact.

Maximum: A .020" feeler gauge should

slide between armature and rotor with

slight contact.

3. Repeat for each inspection slot.

To adjust:

1. If necessary, loosen gap adjustment

nuts until a .016" feeler gauge fits

between armature and rotor.

2. Slide a .020" feeler gauge between

armature and rotor.

3. Tighten gap adjustment nut until there is

slight contact on feeler gauge.

4. Repeat steps 1 – 3 at each inspection

slot.

NOTE: Adjust air gap as evenly as possible.

5. Start unit, engage and disengage PTO.

6. Shut off unit.

7. Recheck air gap and adjust if needed.
