MAINTENANCE
V-belts
Check the belts every 100 hours of operation.
Check for severe cracking and large nicks.
The belt will show some small cracks in normal
operation. The belts are not adjustable. Replace
the belts if they begin to slip from wear.
Deck Belt Removal
1. Park on a level surface and apply the parking
brake. Lower the deck to the lowest cutting
position.
2. Remove both belt shields.
3. Remove the debris that has accumulated
around the cutter housings and the deck
surface.
4. Push inward on the idler arm to release the
tension on the belt.
5. Slip the belt over the top of the cutter housing
pulleys and remove the belt from the deck.
Deck Belt Installation
NOTE: For ease in installing the deck belt, refer to
the routing decal on the top of the deck.
1. Wrap the deck belt around the electric clutch
pulley located on the engine shaft.
2. Route the belt forward and up onto the deck.
3. Place the belt around the idler pulley.
4. Wrap the belt around the stationary idler
pulley and around the mandrel housings.
5. Push inward on the idler arm and carefully
route the belt over the stationary idler pulley.
Once the belt is properly routed, slowly
release the idler arm to tension the belt.
6. Make sure the belt routing matches the deck
decal and that the belt does not have any
twists.
7. Tighten the belt guide and replace the belt
shields on both mandrel housings. The belt
guide should be perpendicular to the belt
when installation is complete.

Adjusting the Mower Deck
Leveling deck
Adjust the deck while the mower is on a level
surface. Make sure the tires are inflated to
the correct pressure. See Technical Data /
Transmission. If tires are under or over inflated,
the deck cannot be correctly adjusted. Raise the
deck to the highest (transport) position.
The deck must be adjusted slightly higher in the
rear.
NOTE: To insure the precision of the leveling
procedure, the mower deck drive belt must be
installed before leveling the deck.
1. Wear heavy gloves. Turn each outer blade tip
to align front to rear with the deck side-to-side.
2. Measure from the floor surface up to the
bottom of the blade tip on the discharge side
of the mower deck. Record the measurement.
3. Move to the opposite side, check that
measurement is the same. If adjustment is
required—with a 3/4" or adjustable wrench,
turn the lift link adjustment nuts on either
side counter clockwise to lower or clockwise
to raise. Adjust until both measurements are
equal.
4. Turn any blade to align with the deck front-to-
rear. If the front blade tip does not measure
1/8" to 1/2" higher in the rear—with a 5/8"or
adjustable wrench, turn the nuts on the front
suspension linkage. Clockwise raises the front
of the mower, counter clockwise will lower the
front. Adjust nuts until rear of mower deck is
