Caster Wheels; Anti-Scalp Rollers; V-Belts - Craftsman Z6800 Operator's Manual

MAINTENANCE

Caster Wheels

Check every 200 hours. Check that wheels rotate
freely.
Foam filled tires or solid tires will void the
warranty.
To replace, remove nut and caster bolt. Pull the
wheel out of the yoke and take care with the
spacer. Reinstall in reverse order. Tighten the
caster bolt and torque to 45 ft-lbs (61 Nm).

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.
IMPORTANT INFORMATION Adjust anti-
scalp rollers with the mower on a flat level
surface. To avoid deck damage, the anti-scalp
rollers must not be adjusted to support the
deck.

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.
2. Lower the deck to the lowest cutting position.
3. Remove both belt shields.
4. Remove the debris that has accumulated
around the cutter housings and the deck
surface.
5. Loosen the nut securing the belt guide.
6. Push inward on the idler arm to release the
tension on the belt.
7. 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 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 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.
