Greasing and Lubrication
Lubricate the machine when shown on the Check Service
Reference Aid decal (Fig. 29) located beneath the seat.
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 PTO, stop the engine, and 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. 29) located beneath the seat.

Checking the Tire Pressure
Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every 50
operating hours or monthly, whichever occurs first
(Fig. 31). Check the tires when they are cold to get the most
accurate pressure reading.
Rear Tires: 13 psi (90 kPa)
Front Tires (castor wheels): 35 psi (139 kPa)
