The fuel tanks are located in the tractor’s fenders. ("FIG. 8") 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. 9") 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 ATZ tractors are equipped with a fuel shutoff valve located on the right fuel tank mount ("FIG. 10").
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.
ENGINE OIL AND FILTER
Check engine oil daily and after every 4 hours of operation. Crankcase dipstick and oil filler tube are
located at the rear of the machine ("FIG. 11"). Tractor must be sitting level when checking oil. Refer to
engine manual and maintenance schedule for oil recommendation and capacities.
Change the engine oil and filter after the first 5 hours of operation, per the engine manufacturer’s
recommendations after that. If tractor is being operated in extremely dirty conditions, then it is
recommended oil be changed more frequently.
