MAINTENANCE
Caster Wheels
Check at 200 hour intervals. Check that wheels
turn freely. If wheels do not turn freely take the
unit to the dealer for service.
Foam filled tires or solid tires will void the
warranty.
Removal and installation
Remove nut and caster bolt. Pull the wheel out of
the yoke and take care of the spacers. Install in
reverse order. Tighten caster bolt.
Anti-scalp Rollers
Anti-scalp rollers are correctly adjusted when
they are slightly off of the ground when the deck
is at the desired cutting height in the operating
position. Anti-scalp rollers keep the deck in the
proper position to help prevent scalping in most
terrain conditions.
The anti-scalp rollers can be set in three
positions:
• Upper position 1-1/2" to 2-1/2" grass
• Middle position 2-1/2" to 4" grass
• Lower position 4" to 6" grass.
The rollers must be approximately 1/4" from the
ground.
V-belts
Check at 100 hour intervals of operation. Check
for severe cracking and large nicks.
NOTE: The belt will show some small cracks in
usual operation.
The belts are not adjustable. Replace belts if they
begin to slip from wear.
Deck Belt Removal
1. Park on a level surface. Apply park brake.
2. Lower the deck into the lowest cutting
position.
3. Remove bolts from belt shields and remove
shields.
4. Remove any dirt or grass that may have
accumulated around the cutter housings and
entire deck surface.
5. Loosen the nut securing the belt guide. Note
the position of the belt guide for reinstallation.
6. Push inward on the idler arm to release the
tension on the belt.
7. Carefully lift the belt over the top of the cutter
housing pulleys and remove 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. Wind the deck belt around the electric clutch
pulley located on the engine shaft.
2. Route the belt forward and up onto the deck.
3. Position the belt around spring loaded idler
pulley.
4. Wind the belt around the stationary idler pulley
and the mandrel housings.
5. Push inward on the idler arm and carefully put
the belt over the stationary idler pulley. When
the belt is correctly routed, slowly release the
idler arm to tension the belt.
6. Double check the belt routing to make sure it
matches the routing decal, and the belt does
not have twists.
7. Set the loosened belt guide into the idler arm
hole and tighten the pulley bolt.
8. Replace belt shields on both mandrel
housings and secure with fasteners.
