Using Proper Fuel (Diesel)

Use the proper diesel fuel to help prevent decreased engine performance and increased exhaust emissions. Failure to follow the fuel requirements listed below can void your engine warranty.

Contact your local fuel distributor for properties of the diesel fuel in your area.

In general, diesel fuels are blended to satisfy the low temperature requirements of the geographical area in which they are marketed.

Diesel fuels specified to EN 590 or ASTM D975 are recommended.

Required fuel properties

In all cases, the fuel shall meet the following properties:

Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially when temperatures are below -20?C (-4?F) or elevations above 1500 m (5000 ft).
Cold Filter Plugging Point (CFPP) below the expected low temperature OR Cloud Point at least 5?C (9?F) below the expected low temperature.
Fuel lubricity should pass a minimum load level of 3100 grams as measured by ASTM D6078 or maximum scar diameter of 0.45 mm as measured by ASTM D6079 or ISO 12156-1.

If a fuel of low or unknown lubricity is used, addition of John Deere PREMIUM DIESEL FUEL CONDITIONER at the specified concentration is recommended.

Sulfur content

• Diesel fuel quality and fuel sulfur content must comply with all existing emissions regulations for the area in which the engine operates.

• Sulfur content less that 0.05% (500 ppm) is recommended for best performance.

• Diesel fuel sulfur content greater than 0.5% (5000 ppm) should not be used.

IMPORTANT: Avoid damage! Do not mix diesel engine oil or any other type of lubricating oil with diesel fuel.


Using Bio-Diesel Fuel

Bio-diesel fuels may be used only if the bio-diesel fuel properties meet the latest edition of ASTM D6751, EN14214, or equivalent specification.

The maximum allowable bio-diesel concentration is a 5% blend (also known as B5) in petroleum diesel fuel.

Consult your local fuel distributor for properties of the bio-diesel fuel available in your area.

Handling and Storing Diesel Fuel

c CAUTION: Avoid injury! Handle fuel carefully. Do not fill the fuel tank when engine is running.

Do not smoke while you fill the fuel tank or service the fuel system.

IMPORTANT: Avoid damage! Do not use galvanized containers—diesel fuel stored in galvanized containers reacts with zinc coating in the container to form zinc flakes. If fuel contains water, a zinc gel will also form. The gel and flakes will quickly plug fuel filters and damage fuel injectors and fuel pumps.


• Fill the fuel tank at the end of each day’s operation to prevent water condensation and freezing during cold weather.

IMPORTANT: Avoid damage! The fuel tank is vented through the filler cap. If a new cap is required, always replace it with an original vented cap.


• When fuel is stored for an extended period or if there is a slow turnover of fuel, add a fuel conditioner to stabilize the fuel and to prevent water condensation. Contact your fuel supplier for recommendations.

Filling Fuel Tank

c CAUTION: Avoid injury! Fuel vapors are explosive and flammable:

• Shut engine off before filling fuel tank.

• Do not smoke while handling fuel.

• Keep fuel away from flames or sparks.

• Fill fuel tank outdoors or in well ventilated area.

• Clean up spilled fuel immediately.

• Use clean approved non-metal container to prevent static electric discharge.

• Use clean approved plastic funnel without screen or filter to prevent static electric discharge.

IMPORTANT: Avoid damage! Dirt and water in fuel can cause engine damage:

• Clean dirt and debris from the fuel tank opening.

• Use clean, fresh, stabilized fuel.

• Fill the fuel tank at the end of each day’s operation to keep condensation out of the fuel tank.

• Use a non-metallic funnel with a plastic mesh strainer when filling the fuel tank or container.


Fill fuel tank at the end of each day’s operation to prevent condensation and freezing during cold weather.

1. Park machine safely. (See Parking Safely in the SAFETY section.)

2. Allow engine to cool.

3. Remove any trash from area around fuel tank cap.

4. Remove fuel tank cap slowly to allow any pressure built up in tank to escape.

5. Fill fuel tank only to bottom of filler neck.

6. Install fuel tank cap.

Raising and Lowering Hood

1. Check to be sure hood latch is free of debris.

2. Lift hood slightly and pull arm (C) on hood support forward to release the support.

3. Slowly lower hood.

4. Push down on front of hood to lock latch.

Checking Wheel Bolts and Hardware

c CAUTION: Avoid injury! Check rim, hub, and axle hardware periodically to prevent possible machine roll-over.

When machine is new or anytime wheel hardware is loosened, tighten all bolts after one hour of operation and every four hours thereafter until proper torque values are maintained.

Tightness of wheel hardware must be maintained according to service interval recommendations. Check wheel bolt tightness as follows:

Front Wheel Bolts

Tighten front wheel bolts alternately to 180 N•m (133 lb-ft).

Rear Wheel Bolts

Tighten rear wheel bolts alternately to 115 N•m (85 lb-ft).

Removing and Installing Wheels

c CAUTION: Avoid injury! Remove wheels safely.

• Use a safe lifting device and support machine securely on jack stands.

• Block front and rear of wheel not raised to prevent machine movement.

• Wheel can be heavy or difficult to handle when removing.

Front Wheel Removal

1. Loosen lug nuts slightly before raising front axle.

2. Raise front of machine and lower onto support stands so that machine is supported by front axle.

3. Remove four lug bolts and wheel.

NOTE: If the front wheels are being removed to perform work on the front axles, lower machine onto suitable stands that will support the machine by the frame.

Front Wheel Installation

1. Install wheels onto axle, insert lug bolts and lightly tighten bolts.

2. Raise front of machine, remove support stands and lower machine to floor.

3. Tighten lug bolts to 180 N•m (133 lb-ft).

Rear Wheel Removal

1. Loosen lug bolts slightly before raising machine rear axle.

2. Raise rear of machine and lower onto support stands so that machine is supported by rear axle.

3. Remove five lug bolts and wheel.

Rear Wheel Installation:

1. Install wheels onto axle, insert lug bolts and lightly tighten bolts.

2. Raise rear of machine, remove support stands and lower machine to floor.

3. Tighten lug bolts to 115 N•m (85 lb-ft).

Checking Tire Pressure

c CAUTION: Avoid injury! Explosive separation of tire and rim parts is possible when they are serviced incorrectly:

• Do not attempt to mount a tire without the proper equipment and experience to perform the job.

• Do not inflate the tires above the recommended pressure.

• Do not weld or heat a wheel and tire assembly. Heat can cause an increase in air pressure resulting in an explosion. Welding can structurally weaken or deform the wheel.

• Do not stand in front or over the tire assembly when inflating. Use a clip-on chuck and extension hose long enough to allow you to stand to one side.

1. Check tires for damage.

2. See tire pressures in SPECIFICATIONS.

3. Check tire pressure with an accurate gauge.

4. Add or remove air, if necessary

Selecting Front Tire Rolling Direction

c CAUTION: Avoid injury! Remove wheels safely.

• Use a safe lifting device and support machine securely on jack stands.

• Block front and rear of wheel not raised to prevent machine movement.

• Wheel can be heavy or difficult to handle when removing.

Machines equipped with directional type tires (such as bar tires) have directional arrows located on the tire sidewall. Under most conditions, tires should be installed with the directional arrow pointing in the direction of travel.

If machine is mainly used for loader operations, lug direction may be reversed to increase tire life and improve traction while backing out of dirt piles.

Move wheel from one side of machine to the other to change tire rolling direction.

Cleaning Plastic Surfaces

IMPORTANT: Avoid damage! Improper care of machine plastic surfaces can damage that surface:

• Do not wipe plastic surfaces when they are dry. Dry wiping will result in minor surface scratches.

• Use a soft, clean cloth (bath towel, diaper, automotive mitt).

• Do not use abrasive materials, such as polishing compounds, on plastic surfaces.

• Do not spray insect repellent near machine.


1. Rinse hood and entire machine with clean water to remove dirt and dust that may scratch the surface.

2. Wash surface with clean water and a mild liquid automotive washing soap.

3. Dry thoroughly to avoid water spots.

4. Wax the surface with a liquid automotive wax. Use products that specifically say “contains no abrasives.”

IMPORTANT: Avoid damage! Do not use a power buffer to remove wax.


5. Buff applied wax by hand using a clean, soft cloth.
