Replacing the Fuel Filter
Replace the fuel filter after every 200 operating hours or
yearly, whichever occurs first.
Never install a dirty filter if it is removed from the fuel
line.
1. Disengage the PTO, set the parking brake, stop the
engine, and remove the key.
2. Allow the machine to cool down.
3. Close the fuel shut-off valve located under the front of
the fuel tank.
4. Squeeze the ends of the hose clamps together and slide
them away from the filter (Fig. 37).
5. Remove the filter from the fuel lines.
6. Install a new filter and move the hose clamps close to
the filter (Fig. 37).
7. Open the fuel shut-off valve.
Greasing and Lubrication
Lubricate the machine when shown on the Check Service
Reference Aid decal (Fig. 38). Grease more frequently
when operating conditions are extremely dusty or sandy.
Grease with No. 2 general purpose lithium base or
molybdenum base grease.
How to Grease
1. Disengage the power take off (PTO) and turn the
ignition key to off. Move levers to neutral locked
position and apply parking brake. Remove the key.
2. Clean the grease fittings with a rag. Make sure to
scrape any paint off 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. 38).

Greasing the Front Caster Pivots
Lubricate the front caster pivots once a year.

2. Remove the hex plug. Thread a grease zerk into hole.
3. Pump grease into zerk until it oozes out around top
bearing.
4. Remove grease zerk in hole. Reinstall hex plug and
cap.
Greasing the Bearings
The cutting unit must be lubricated regularly. Refer to the
Recommended Maintenance Schedule on page 24. Grease
with No. 2 general purpose lithium base or molybdenum
base grease.
