15PN-52886 (4/97)
Use a lithium grease of #2 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 90W gear lube in the gearbox. Oil level is to
be up to plug on side of gearbox. See Figure 9.
Check gearbox 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.
Overfilling the gearbox will cause the excess gear
lube to blow out vent plug. The gear lube could then
ruin the belt.
Driveshaft Lubrication
Lubricate the driveshaft slip joint every 8 operating
hours. Failure to maintain proper lubrication could
result in damage to U-joints, gearbox and driveshaft.
Lower mower to ground.
Apply grease at three locations as shown in Figure 9.
Raise and lower mower several times to distribute
grease.
