Refer to Figure 5-12:
The fuel tanks are located on the mower’s fenders. Total
capacity of the fuel tanks is 12 U.S. gallons. Before filling,
push blade engagement switch (OFF), move both control
levers (OUT), set park brake (ON) and turn switch key
(OFF). Allow engine to cool before filling tanks.
Clean dirt from around fuel tank cap. Remove cap and
begin filling. Do not fill fuel tanks to the top if mowing on
hilly terrain or in hot weather. Gas can rise up to the fuel
cap vent hole and seep out. When finished, screw cap
back on securely and wipe up any spilled gasoline. Use
regular unleaded gasoline with an (R+M)/2 octane rating
of 87 or higher.

Using a fuel stabilizer/conditioner in the fuel can provide
benefits such as:
1.
Keeps gasoline fresh during storage of 90 days or
less. Drain fuel tanks if storage is longer.
2.
Cleans engine during operation.
3.
Eliminates gum-like varnish build-up in the fuel system.
Be sure to add the correct amount of gas stabilizer/
conditioner. For best results, follow manufacturer’s
directions.

IMPORTANT: The fuel system can be damaged if
the wrong fuel is used. Never use methanol, lead
gasoline or unleaded gasoline containing more than
10% ethanol. Do not mix oil with gasoline.
The fuel filter is installed in the fuel line between the
Left/Right Fuel Tank Valve and engine fuel pump.
Location of fuel filter will vary depending on which engine
your mower is equipped with. See engine owner’s
manuals for exact location of fuel filter and instructions
on removal and installation.
Refer to Figure 5-13:
Replace filter annually or after every 100 hours of
operation, whichever occurs first. Be sure to install the
filter with Flow Arrow pointing towards the engine side of
the fuel line. Always check fuel line hoses for any cracks
or leaks. Replace as needed.
