not fill tank with engine running or while engine
is hot; 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. Read and observe safety precautions at
front of this manual.
WARNING: Fuel System Under Pressure! The
EFI fuel system operates under high pressure,
and the fuel filter and fuel line used must be
approved system components only. Use of
substitute parts can result in system failure,
gasoline leakage and possible explosion.
The fuel tanks are located in the tractor’s fenders. (Fig.
4-7) Total capacity for the fuel tanks is 15 U.S. gallon (56.8
liter)
Use regular unleaded gasoline with an octane rating of 87
or higher.
The fuel filter (Fig. 4-8) is installed in the fuel line
between fuel tanks and engine fuel pump. Replace filter
annually or after every 500 hours of operation, whichever
occurs first.
When replacing the fuel filter, check the fuel line hoses
and fuel shut-off valve grommet for any cracks or leaks.
Replace as needed.
Hustler Z and Super Z tractors are equipped with a fuel
shutoff valve located on the right fuel tank mount (Fig. 4-
9a). Rotate the valve to the middle position (shown) to
prevent fuel flow to the fuel pump. The forward position
allows fuel to flow from the right fuel tank to the fuel pump.
The rear position allows fuel to flow from the left fuel tank
to the fuel pump. Close this valve to prevent fuel flow to the
engine when servicing the fuel system or when transporting
the unit on a trailer or truck.
