Using Proper Fuel

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.


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.

Using Proper Fuel (Gas)

Use regular grade unleaded fuel with an octane rating of 87 octane or higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE reformulated fuel are acceptable. Do not use fuel or additives containing methanol as engine damage can occur.

Always use fresh, clean fuel that is purchased in a quantity that can be used within approximately 30 days, or add fuel stabilizer.

Fuel is blended to give best seasonal performance. To avoid engine performance problems such as hard starting or vapor lock, use in-season fuel. Use fuel during warm weather that was purchased during that season, and use fuel during cold weather that was purchased during that season.

Fuel can become stale in machines with engines that are used seasonally or infrequently during a season. Stale fuel can produce varnish and plug carburetor or injector components which can affect engine performance.

Keep fuel storage container tightly covered and in a cool area out of direct sunlight. Fuel can break down and degrade if not sealed properly or exposed to sun and heat.

Condensation may collect in the fuel tank because of a variety of operating or environmental conditions and, over time, may affect your machine’s operation. Fill fuel tank at the end of daily use and store fuel in plastic containers to reduce condensation.

For best year-round performance and fuel-handling, add stabilizer to fuel immediately after fuel purchase. Such practice helps prevent engine performance problems and allows fuel storage in the machine all year without draining.

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.

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.

NOTE: Refer to the SPECIFICATIONS section for tire pressures.

2. Check tire pressure with an accurate gauge.

3. Add or remove air, if necessary.

Tightening Wheel Hardware

NOTE: Tighten bolts after first 50 hours of operation and every 100 hours thereafter.

1. Tighten all wheel bolts alternately to 81–95 N•m (60–70 lb-ft.).

Adjusting Park Brake

A properly adjusted park brake should have no play in the pedal when the brake is in the unlocked position. The pedal should return and contact the rear of the opening in the operator foot platform.

As the brake pads wear, the brake pedal will have to be depressed further to fully engage the brakes. If the brake pedal travel is too far for operator comfort, the brake adjusting rod can be adjusted.

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

2. Loosen jam nut (A) on the brake adjusting rod (B).


M97399

3. Remove cotter key (C) and drilled head pin (D) from park brake linkage.

NOTE: Be careful not to turn out the yoke too far on either end of the threaded adjustment rod. The maximum length of thread to be exposed at each end of the rod should be 25mm (1 in.).

4. Hold brake adjusting rod (B). Turn front yoke (E) counter-clockwise until the park brake pedal needs to be depressed slightly to install drilled pin back into front yoke.

5. Install drilled head pin (D) and cotter key (C).

6. Check adjustment.

7. If further adjustment is required, refer to the Technical Manual or see a John Deere distributor.

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.
