MAINTENANCE

V-belts

Check every 100 hours of operation. Check for
severe cracking and large nicks. The belts are not
adjustable. Replace the belts if they begin to slip
from wear.
NOTE: The belt will show some small cracks in
normal operation.
Deck Belt
Deck Belt Removal
Park on a level surface. Apply park brake. Lower
the deck into the lowest cutting position.
1. Remove foot plate and belt shields.
2. Remove dirt or grass that may have
accumulated around the cutter housings and
entire deck surface.
3. Using a ratchet or a breaker bar and 9/16"
socket in the square opening in the idler arm,
shift the arm counter clockwise to relieve the
tension on the belt.
4. Carefully lift the belt over the top of the cutter
housing pulleys.
5. Remove the belt from around the electric
clutch on the engine shaft.
Deck Belt Installation
NOTE: For ease in installing the deck belt, refer to
the routing decal on the cutting deck.
1. Wrap the deck belt around the electric clutch
pulley that is located on the engine shaft.
2. Route the belt forward between the spring
loaded and stationary pulleys.
3. Place belt around spring loaded 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 belt over stationary idler pulley. Once
belt is properly routed, slowly release idler
arm to tension belt.
6. Check that there are not twists in the belt and
that the routing matches the routing decal.
7. Replace belt shields on both mandrel
housings and secure with fasteners.
Pump Belt
The belts are not adjustable. Replace belts if they
begin to slip from wear.
Replacing Pump Belt
Park the mower on a level surface. Engage the
park brake.
Belt Removal
From the top side of the deck:
1. Remove the deck belt (see Deck Belt
Removal in this section of the manual).
2. Tilt seat forward to access fan covers.
Remove both fan covers.
From the underside of the mower:
3. Remove clutch stop to access the belt.
4. With a ½" breaker bar and using the square
opening in the pump idler arm, shift the arm to
create slack in the belt.
5. With the idler arm in the slack position, slip a
screwdriver, clevis pin or similar into the
hole in the plate that sits between the two fan
covers. This will keep the idler in the extended
position and allow removal of the breaker bar.
6. Remove belt from the engine and pump
pulleys over the top of the fans.
