Figure 8. Lubrication Points (Grease)

Lubrication

Lubricate the unit at the following lubrication points as

well as those shown in Figure 8.

Grease:

• front caster wheel axles

• front caster spindle bosses

• front axle center pivot

• mower blade spindles

• mower deck idler arm

• mower deck lift motor screw (located up under

right fender)

belts and pulleys. Remember to wipe fittings and sur-

faces clean both before and after lubrication. Use grease

fittings when present. Disassemble parts to apply grease

to moving parts when grease fittings are not installed.

Not all greases are compatible. Use automotive-type

lithium grease.

* Some blade spindles have grease fittings above the

mower deck, while others have grease fittings below

the deck.
