DANGER!
Observe usual fuel handling precautions; do not smoke while
refueling, do not fill tank with engine running or while engine is
hot. Clean up any gasoline spills.
Allow engine to cool before storing machine inside a building.
Keep fuel away from open flame or spark and store machine
away from open flame or spark if there is fuel in the tank.
Use extra caution when handling gasoline and other fuels. They
are flammable and vapors are explosive. A fire or explosion
from gasoline can burn you and others and can damage
property. Refuel outdoors preferably, or in well ventilated
areas. Never attempt to start engine when there is a strong odor
of gasoline fumes present. Locate and correct cause. Store
gasoline in an approved container and keep it out of the reach
of children. Never buy more than a 30 day supply of gasoline.
Do not fill gasoline containers inside a vehicle or on a truck or
trailer as interior carpets or plastic truck bed liners may
insulate the container and slow the loss of any static charge.
When practical, remove equipment from the truck or trailer and
refuel the equipment with its wheels on the ground. If this is not
possible, then refuel the equipment on the truck or trailer using
a portable container and not a gasoline dispenser nozzle. If a
gasoline dispenser nozzle must be used, keep the nozzle in
contact with the rim of the fuel tank or container opening at all
times until fueling is complete.

WARNING!
Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors can cause serious injury and
illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas tank or conditioner
opening.
Keep gas away from eyes and skin.
The fuel tanks are located in the tractor’s fenders. Total
capacity for the fuel tanks is 12.2 U.S. gallon.
When filling the fuel tanks disengage blade engagement,
place control levers in parkbrake position,and stop tractor
engine. Clean around the fuel tank cap and remove the
cap and begin filling. When finished, screw the cap on
securely and wipe up any spilled gasoline. Use regular
unleaded gasoline with an octane rating of 87 or higher.
Using a fuel stabilizer/conditioner in the tractor can
provide benefits such as:
1. Keeps gasoline fresh during storage of 90 days or
less. For longer storage, drain the fuel tanks.
2. Cleans the engine during operation.
3. Eliminates gum-like varnish build-up in the fuel system.
Add the correct amount of gas stabilizer/conditioner to the
gas. Follow the gas stabilizer/conditioner manufacturer’s
directions for best results. The fuel filter (Figure 4-7) is
installed in the fuel line between fuel tanks and engine fuel
pump on the rear left side of the engine. Replace filter
annually or after every 100 hours of operation, whichever
occurs first. For fuel filter removal refer to the engine
owner’s manual. When replacing the fuel filter, check the
fuel line hoses for any cracks or leaks. Replace as
needed. A fuel shut-offvalve is located on the outlet port of
each fuel tank. Refer to Figure 4-6. Close these valves
(turn clockwise) to prevent fuel flow to the engine.
Draining the fuel tank
1. Park the unit on a flat surface. Stop the engine and
remove the ignition key. Make sure blade engagement
switch is in the down (OFF) position. Place control
levers in the park brake position. Disconnect negative
battery cable.
2. Close the fuel shut-off valve on the fuel tank to be
drained.
3. Trace the fuel line from the shut-off valve to the
Left/Right Fuel Tank Valve (Refer to Figure 2-3 on
page 9). Loosen the hose clamp and remove the fuel
line from the tee.
4. Place the end of the fuel line into a gas can or a drain
pan and open the fuel shut-off valve to drain the hose
from the fuel tank.
5. When fuel tank is drained re-route the fuel line to the
Left/Right Fuel Tank Valve and attach to the valve.
Clamp fuel line to valve.
6. Fill fuel tank with proper grade of gasoline and open
shut-off valve.
When replacing the fuel filter, check the fuel line hoses for
IMPORTANT: Never use methanol, gasoline
containing methanol, or gasohol containing more than
10% ethanol because the fuel system could be
damaged. Do not mix oil with gasoline.
IMPORTANT: Do not use fuel additives containing
methanol or ethanol.
