Anti-scalp Rollers

Anti-scalp rollers are properly adjusted when they are just 
slightly off of the ground when the deck is at the desired 
cutting height in the operating position. Anti-scalp rollers then 
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 38 to 64 mm grass

• 

Middle position 64 to 102 mm grass

• 

Lower position 102 to 128 mm grass.

The rollers should be approximately 6.5 mm from the ground. 

Caster Wheels

Check every 200 hours. Check that wheels rotate freely. If 
wheels do not rotate freely take the unit to your 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.

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 every 100 hours of operation. Check for severe 
cracking and large nicks.
NOTE: The belt will show some small cracks in normal 
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 parking 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.  Remove tension on the belt by moving the idler arm.
6.  Carefully slip belt up over the top of the cutter housing 

pulleys and remove belt. Rolling belt over the pulleys may 
damage the belt.

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 that is 

located on the engine shaft.

2.  Route the belt forward and up onto the deck.
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.  Double check belt routing to make sure it matches the 

routing decal, and the belt does not have any twist. 
Correct as needed.

7.  Replace belt shields on both mandrel housings and 

secure with fasteners.
