Greasing and Lubrication

Lubricate the machine when shown on the Check
Service Reference Aid decal (Figure 26). Grease
more frequently when operating conditions are
extremely dusty or sandy.
Grease Type: General-purpose grease.
How to Grease
1. Disengage the PTO, move the motion control
levers to the neutral locked position and set
the parking brake.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Clean the grease fittings with a rag. Make
sure to scrape any paint off the front of the
fitting(s).
4. Connect a grease gun to the fitting. Pump
grease into the fittings until grease begins to
ooze out of the bearings.
5. Wipe up any excess grease.
Greasing the Front Caster Pivots
Lubricate the front caster pivots once a year.
1. Remove the dust cap and adjust the caster
pivots. Keep the dust cap off until greasing
is done. Refer to Adjusting the Caster Pivot
Bearing in Drive System Maintenance, page 34.
2. Remove the hex plug. Thread a grease zerk
into the hole.
3. Pump grease into the zerk until it oozes out
around the top bearing.
4. Remove the grease zerk in the hole. Install the
hex plug and cap.
