MAINTENANCE
LUBRICATION INFORMATION
Do not let excess grease collect on or around
parts, particularly when operating in sandy areas.
The accompanying illustration shows lubrication
points. The chart gives the frequency of lubrication
in operating hours, based on normal operating
conditions. Severe or unusual conditions may
require more frequent lubrication. Some reference
numbers have more than one location; be sure
you lubricate all locations.
In addition to the lubrication points shown, at least
once
a
year, oil the six mower lift pivot points.
Use a lithium grease of
consistency with a
MOLY
(molybdenum disulfide) additive for all
locations. Be sure to clean fittings thoroughly
before attaching grease gun. When applied
according to the lubrication chart, one good pump
of most guns is sufficient.
Use
SAE
gear lube in the gearbox. Check
gear box daily for evidence of leakage at both
seals and the gasket between the housing and
cover.
If
leakage is noted, repair immediately.
There may be a small amount of lube emitted from
the vent plug; this is not considered leakage.
Check lube level every
50
hours by removing the
vent plug and checking the gauge on the bottom
of the vent plug. The oil level should show 1 in. on
the gauge. You may also check the oil by using an
Allen wrench to remove the level plug in the front of
the gearbox. Do not over lubricate. Over-filling the
gearbox will cause the excess gear lube to blow
out vent plug. The gear lube could then ruin the
belt.
Drive Shaft Lubrication
Lubricate the drive shaft slip joint every 8 operating
hours. Failure to maintain proper lubrication could
result in damage to U-joints, gearbox and drive
shaft.
Lower mower to ground and apply a bead of
grease all around the male half where it meets the
female half. Raise and lower mower several times
to distribute grease.
