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. 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.

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 buildup in the fuel system. IMPORTANT: Do not use fuel additives containing methanol or

ethanol.

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 (Fig. 9-13A, 9-13B & 9-13C) 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 and fuel shut- off valve grommet for any cracks or leaks. Replace as needed.

Fuel Shut-off Valves

On early units a fuel shut-off valve is located on the outlet port of each fuel tank. (Fig. 9-14) Close these valves (turn clockwise) to prevent fuel flow to the engine. To drain a fuel tank equipped with this fuel shut-off

valve use the following method:

1.Park the unit on a flat surface. Stop the engine and remove the ignition key. Make sure deck clutch 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 both of the fuel tanks.

3.Trace the fuel line from the shut-off valve to the tee. Loosen the hose clamp and remove the fuel line from the tee.

4.Place the end of the fuel line in a clean certified fuel container and open the fuel shut-off valve to drain the fuel from the fuel tank.

5.When fuel tank is drained re-route the fuel line to the tee and attach to the tee. Clamp fuel line to tee.

6.Fill fuel tank with proper grade of gasoline and open shut-off valves. Current production units have a fuel shut-off valve (Hustler p/n

745059) located behind the seat to the right side of the operator. (Fig. 9-15) Close this valve (center position) to prevent fuel flow to the engine. The valve’s two other positions are front and rear. To drain a fuel tank equipped with this fuel shut-off valve kit use the following method:

1.Park the unit on a flat surface. Stop the engine and remove the ignition key. Make sure deck clutch switch is in the down (OFF) position. Place control levers in the park brake position. Disconnect negative battery cable.

2.Turn the fuel valve to the closed position (middle position). Fig. 9- 15

3.Disconnect the tank to fuel valve line from the valve and clamp or cap the end of it.

4.Route the fuel line until it is lower than the fuel tank fitting.

5.Place the end of the fuel line in a clean certified fuel container and unclamp or uncap the line to permit the fuel to drain from the fuel tank.

6.When fuel tank is drained re-route the fuel line to the shut-off valve and attach it to the tee. Clamp fuel line to shut-off valve.

7.Fill fuel tank with proper grade of gasoline and open shut-off valve (front or rear position).
