CHAIN DRIVES

ADJUSTMENT

To adjust the drive chains, the body must be removed and shims added behind the transaxle. Loosen 4 bolts which hold the transaxle to the frame. Insert shims as needed for adjustment between transaxle and mount plates. When properly adjusted, the slack span at the mid -point of the chain should have a total possible movement perpendicular to the chain of about 9/16". Tighten the 4 bolts which hold the transaxle to the frame. Replace chain when rollers become loose, chain breaks, or chain fails to operate properly.

LUBRICATION

1.Chains: Proper lubrication is important for effective roller chain operation. Use high quality lubricating oil (do not use grease or extra heavy oil) and apply drops of oil to the chain joints every 10-15 hours of operation.

2.Front Caster Assembly: Each caster assembly has a grease fitting located on the under side of the bearing. For best results, use any good multi-purpose grease every 10-15 hours of operation.

3.All other Bearings: All other bearings o n your mower are sealed and require no lubrication.

WHEELS AND TIRES

Correct tire pressure is essential to the correct operation of the machine. The correct pressure for the drive tires is 8-10 Ibs. The front tires should be inflated to 20-24 Ibs. Lug nuts should be checked periodically.
