Tire Pressure
WARNING! Maximum tire pressure under any
circumstances is 30 psi. Equal tire pressure should be
maintained at all times. Never exceed the maximum
inflation pressure shown on the sidewall of the tire.
The recommended operating tire pressure is:
Approximately 10 psi for the rear tires
Approximately 14 psi for the front tires
IMPORTANT: Refer to the tire sidewall for exact tire
manufacturer’s recommended or maximum psi. Do not
overinflate. Uneven tire pressure could cause the cutting deck to
mow unevenly.
Gas and Oil Fill-up
The gasoline tank is located under the hood and has a capacity
of 1-½ gallons. Do not overfill.
WARNING! Use extreme care when handling
gasoline. Gasoline is extremely flammable and the
vapors are explosive. Never fuel machine indoors or
while the engine is hot or running. Extinguish
cigarettes, cigars, pipes, and other sources of ignition.
Service the engine with gasoline and oil as instructed in the
separate Engine Operator/Owner Manual packed with your
tractor. Read instructions carefully.
IMPORTANT: Your tractor is shipped with motor oil in the
engine. However, you MUST check the oil level before
operating. Be careful not to overfill.
Setting the Deck Gauge Wheels (if so equipped)
Move the tractor on a firm and level surface, preferably
pavement, and proceed as follows
Select the height position of the cutting deck by placing
the deck lift lever in the normally desired mowing height
setting (any of the six different cutting height notches on the
right fender).
Check the gauge wheels for contact or excessive clearance
with the surface below. The deck gauge wheels should
have between ¼-inch and ½-inch clearance above the
ground as follows:
If the gauge wheels have excessive clearance or contact with the
surface, adjust as follows:
Raise the deck lift handle to its highest setting.
Remove the gauge wheels by removing the lock
nuts and shoulder screws which secure them to the
deck. See Fig. 3-9
Place the deck lift lever in the desired mowing
height setting.
Reinsert the shoulder screw (with each gauge
wheel) into the index hole that leaves approximately
½-inch between the bottom of the wheel and the
pavement.
Refer to Leveling the Deck in the Maintenance section of this
manual for more detailed instructions regarding various deck
adjustments.
