MAINTENANCE

Pump belt

Check belt every 100 hours for excessive wear.

To replace belt. Relieve tension on the deck belt and remove deck belt from clutch. See Deck belt in Maintenance section. Loosen bolt on the clutch tie down and rotate out of the way.

Using a 1/2 drive ratchet inserted into the square hole in the pump idler arm, relieve the tension on the pump belt and remove belt.

To reinstall belt. Swing pump idler pulley out toward engine to route belt around it. Then route belt around the pulley for the left pump first (right hand pulley in the illustration).

Reinstall idler spring and use the ratchet to rotate idler so the belt may be installed all the way around the last pulley.

Checking the Blades

In order to attain the best mowing performance, it is important that the blades are well sharpened and not damaged.

WARNING!

Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling.

Bent or cracked blades or blades with large nicks should be replaced.

Check the blade mounts.

IMPORTANT INFORMATION

The sharpening of blades should be carried out by an authorized service workshop.

Damaged blades should be replaced when hitting obstacles that result in a breakdown. Let the service workshop decide whether the blade can be repaired/ground or must be discarded.
