Caster Wheels; V-Belts; Adjusting The Mower Deck - Craftsman Z6300 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).

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. Push inward on the idler arm to release the
tension on the belt.
6. 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. Check the belt routing to make sure it matches
the routing decal, and the belt does not have
twists.
7. Replace belt shields on both mandrel housings
and secure with fasteners.

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 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.
