Hustler Turf 3500, 3700 owner manual Diesel fuel, Refueling the Tractor

Store diesel fuel in an approved container and keep it out of the reach of children.

Do not fill diesel fuel containers inside a vehicle or on a truck or trailer bed with interior carpets or plas- tic truck bed liners. Always place diesel fuel con- tainers on the ground away from your vehicle before filling.

When practical, remove diesel fuel-powered equip- ment from the truck or trailer and refuel the equip- ment 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 dis- penser nozzle. If a fuel dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fuel- ing is complete. Do not use a nozzle lock-open device.

Never use diesel fuel or gasoline for cleaning parts. Read and observe safety precautions elsewhere in this manual.

WARNING: Diesel fuel is harmful or fatal if swal- lowed.

Long-term exposure to vapors can cause serious injury and illness.

Avoid prolonged breathing of vapors.

Keep face away from nozzle and fuel tank or diesel fuel container opening.

Keep diesel fuel away from eyes and skin.

If diesel fuel is spilled on clothing, change clothing immediately.

WARNING: Under no circumstances should gas- oline, alcohol, or gasohol be added to diesel fuel. These combinations can create an increased fire or explosive hazard.

WARNING: Fuel System Under Pressure! Fuel in the injection system is under high pressure and can penetrate the skin. Unqualified persons should not remove or attempt to adjust a pump injector, nozzle or any part of the fuel injection system.

Do not use your hand to check for leaks. Use a piece of cardboard or paper to search for leaks.

If any fluid is injected into the skin, obtain medical attention immediately or gangrene may result. Failure to follow these instructions can result in seri- ous injury.

Check the fuel line periodically as it is subject to wear and aging, fuel may leak onto the engine which could cause a fire.

IMPORTANT: Do not fill tank to capacity. Allow room for expansion.

IMPORTANT: If the original fuel tank cap is lost, always replace it with a Hustler approved cap. A “will fit cap” may not be safe.

Diesel fuel

• Use clean, quality No. 1-D or No. 2-D fuel

•Use No. 1-D fuel if the ambient temperature is expected to be lower than 39 degrees F (4 degrees C) or if the tractor is to be used at an altitude exceeding 5000 ft. (1524 m).

•Use diesel fuel with a pour point of at least 10°F (12°C) below the expected ambient temperature to prevent fuel flow problems in cold weather.

•Keep dirt from entering the fuel tank.

•Sulfur content of the fuel should be no more than 0.05%.

•Sediment and water content should not exceed 0.05%.

•Minimum cetane number is 40. Low temperature or high altitude operation may require use of fuel with a higher Cetane number.

•Use properly mixed winter fuel when temperatures are extremely cold. In most areas, diesel fuel is prop- erly blended for summer and winter grades as ambi- ent temperatures change. In winter, use winter grade diesel fuel only. Otherwise, the fuel may cloud and block the fuel system.

Refueling the Tractor

The fuel tank filler cap is located at the left side of the tractor hood. Before removing the cap, wipe all dust and dirt from around the cap to prevent debris from falling into the tank while filling. Figure 4-10

Use an approved fuel container and check the inside of the container periodically for cleanliness. Fuel tank capacity is 13.33 gallons (50.5L).

NOTE: The fuel cap is a vented-type. Use only an approved Hustler replacement cap to prevent fuel system- related problems.

If there is no filter on the storage tank or fuel container, filter the fuel through a 100-mesh or finer screen when filling the mower fuel tank. Keep the mower tank as full as possible (without filling to capacity) to minimize condensation.

NOTE: It is a good practice to fill the fuel tank at the end of each day, as this will reduce overnight condensation.
