Servicing the Spark Arrester
Inspect the spark arrester every 50 hours for damage, such
as holes in the screen, and for buildup on the screen. If it is
damaged, replace it with a new spark arrester. If it is dirty,
remove it and clean the screen with a wire brush and/or
soak it in solvent.
Greasing and Lubrication
Lubricate the machine when shown on the Check Service
Reference Aid decal (Fig. 46). Grease more frequently
when operating conditions are extremely dusty or sandy.
Grease Type: General-purpose grease
How to Grease
1. Disengage the power take off (PTO) and stop the
engine. Move the levers to the neutral locked position
and apply the parking brake. Remove the key.
2. Clean the grease fittings with a rag. Make sure to scrape
any paint off of the front of the fitting(s).
3. Connect a grease gun to the fitting. Pump grease into
the fittings until grease begins to ooze out of the
bearings.
4. Wipe up any excess grease.
Where to Add Grease
Lubricate the grease fittings as shown on the Check
Service Reference Aid decal (Fig. 46).

Greasing the Front Castor Pivots
Lubricate the front castor pivots once a year.
1. Remove the hex plug and cap. Thread a grease zerk into
the hole.
2. Pump grease into the zerk until it oozes out around the
top bearing.
3. Remove the grease zerk in the hole. Install the hex plug
and cap.
Greasing the Bearings
The cutting unit must be lubricated daily; refer to the
Recommended Maintenance Schedule, page 27. Grease
with No. 2 general purpose lithium base or molybdenum
base grease.
Important Make sure that the cutting unit spindles are
full of grease daily.
1. Stop the engine, set the parking brake, remove the key,
and disconnect the spark plug wire(s) from the spark
plug(s).
2. Grease the fittings on the three spindle bearings until
grease comes out of the lower seals (Fig. 47).
