Change hydraulic system filter element after first 50 hours of tractor
operation, then replace filter and oil in reservoir every 500 hours thereafter.
Fig. 4-2
The system filter is located in front of the hydraulic reservoir. A standard
oil filter wrench is used to change filter, threads are right handed. Use a
Hustler approved filter element only.
IMPORTANT: Prefill the filter element with clean oil, before installing,
to prevent drawing air into the system pump.
Fuel system
DANGER: Observe usual fuel handling precautions:
Do not smoke while refueling. Extinguish all cigarettes,
cigars, pipes and other sources of ignition.
Do not remove fuel cap or fill tank with engine running or
while engine is hot. Clean up any fuel 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 or pilot light such as on a
water heater or appliances.
Use extreme care when handling gasoline and other fuels.
They are extremely flammable and vapors are explosive. A
fire or explosion from fuel can burn you and others and can
damage property.
Refuel outdoors. Never refuel or drain the fuel from the
machine indoors.
Never attempt to start engine when there is a strong odor of
gasoline or diesel fuel fumes present. Locate and correct
cause.
Store fuel in an approved container and keep it out of the
reach of children. Never buy more than a 30 day supply of
fuel.
Always place fuel containers on the ground away from your
vehicle before filling.
Do not fill fuel containers inside a vehicle or on a truck or
trailer bed with interior carpets or plastic truck bed liners.
Always place fuel containers on the ground away from your
vehicle before filling.
When practical, remove gas-powered equipment from the
truck or trailer and refuel the equipment with its wheels on
the ground. If this is not possible, then refuel such equipment
on the truck or trailer using a portable container and not a fuel
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. Do
not use a nozzle lock-open device.
Read and observe safety precautions elsewhere in this
manual.
WARNING: Gasoline or diesel fuel 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 fuel container
opening.
Keep gas away from eyes and skin.
If fuel is spilled on clothing, change clothing immediately.
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.
Gasoline units
The fuel tanks are located in the tractor’s fenders.
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.
A fuel shut-off valve is located on each tractor. The location and
operation of the fuel valve will vary depending upon the unit. Close the
fuel valve to prevent fuel flow to the engine. The valve’s two other
positions will allow fuel to be drawn from either one or the other fuel tank.
Fig. 4-3
Diesel units
The fuel tanks are located in the tractor’s fenders. These engines
requires number 2 diesel fuel only.
Hustler Z Shibaura Diesel tractors are equipped with a fuel shutoff valve
located to the right rear of the seat. Rotate the valve to the middle position
to allow fuel to flow from the right fuel tank to the fuel pump. The right
position prevents fuel flow to the fuel pump. The left 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. Fig. 4-4
If the diesel fuel system runs dry, use the following procedure when re-
starting the engine:
1. Refill the fuel tanks.
2. Make sure the fuel shutoff valve is turned to the full fuel tank.
3. Take the priming bulb and compress it until it becomes firm. Fig. 4-5
4. Try and start the engine. If it will not start after 15 seconds of
cranking, repeat Step 3.
5. If after trying several tries, the engine still will not start, contact your
Hustler Dealer.
Engine oil and filter
Check engine oil daily and after every 4 hours of operation. Tractor
must be setting 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 (50
