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 pro -
perly.
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 underside 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 on 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.
