Gas and Oil Fill-up
OIL
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.
Service and check the engine oil as instructed in the separate
Engine Operator/Owner Manual packed with your tractor. Read
the instructions carefully.
Gasoline
The gasoline tank is located under the hood. 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.
NOTE : Purchase gasoline in small quantities. Do not use gasoline
left over from the previous season, to minimize gum deposits in
the fuel system.
• This engine is certified to operate on unleaded gasoline.
For best results, fill the fuel tank with only clean, fresh,
unleaded gasoline with a pump sticker octane rating of 87
or higher.
• Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline
by volume) is an approved fuel. Other gasoline/alcohol
blends, such as E85, are not approved.
• Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline
blends (up to a maximum of 15% MTBE by volume) are
approved fuels. Other gasoline/ether blends are not
approved.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. Fill tank to no more than 1/2
inch below bottom of filler neck to allow space for fuel
expansion.
• Never remove gas cap or add fuel while the engine is hot or
running. Allow engine to cool at least two minutes before
refueling.
• If gasoline is spilled, wipe it off the engine and equipment.
Move machine to another area. Wait 5 minutes before
starting the engine.
To Add Gasoline
1. Turn the engine off and let engine cool at least 2 minutes
before removing the fuel cap. The gasoline tank is located
under the hood. Remove the fuel cap by turning it
counterclockwise.
2. Fill the fuel tank with gasoline. Use only clean, fresh (no more
than 30 days old), unleaded gasoline. Fill tank to the base
of the filler neck to allow space for fuel expansion. DO NOT
TOP OFF THE TANK WITH FUEL.
3. Reinstall the fuel cap.
IMPORTANT:
Do not overfill the tank. Fill tank to the base of
the filler neck to allow space for fuel expansion. Do NOT Top Off
the tank with fuel. See Figure 3-6.

Setting the Deck Gauge Wheels (if so equipped)
Move the tractor on a firm and level surface, preferably
pavement, and proceed as follows:
1. 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).
2. Check the gauge wheels for contact or excessive clearance
with the surface below. The deck gauge wheels should
have between ¼" and ½" clearance above the ground.
If the gauge wheels have excessive clearance or contact with the
surface, adjust as follows:
a. Raise the deck lift handle to its highest setting
b. Remove the front and rear gauge wheels by
removing the lock nuts and shoulder screws which
secure them to the deck. See Figure 3-7.
Figure 3-7
c. Place the deck lift lever in the desired mowing height
setting.
d. Reinsert the shoulder screw (with each gauge
wheel) into the index hole that leaves approximately
½" 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.
