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.

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.

Check Wheel Bolt Torque

Check all wheel bolts for proper torque.

Adjusting Park Brake

1. Park machine on level surface and turn off engine.

2. Block rear wheels and unlock park brake.

c CAUTION: Avoid injury! The machine may fall or slip from an unsafe lifting device or supports, injuring anyone beneath it.

• Remove key before raising machine.

• Use a safe lifting device rated for the load to be lifted.

• Lower machine onto stable supports or jack stands and block wheels before servicing.

3. Support the front wheels off the ground safely. Use jack stands.


MX22899

4. Remove wheel (A).


MX22900

5. Loosen bottom nut (B) on the pull rods (both sides).

NOTE: Make sure park brake pedal does not contact floor plate with brakes fully engaged.

6. Tighten coupler nut (C) while rotating wheel until brake pads begin to contact disk. Loosen coupler until brake releases. Tighten bottom nut (B) to (both sides).

7. Tighten top jam nut (D) (both sides)

8. Repeat for left brake.

9. Additional adjustment is available at the brake and pedal end of the brake cable.

10. Loosen jam nut (E) and adjust coupler nut (F).

11. Repeat for left brake.

Checking and Adjusting Toe-In

1. Park on a level surface with rear wheels in straight forward position.

2. Lower cutting units. Lock park brake and shut off engine.


M71044

3. Measure distance (A) between tire beads at front of tire. Measure at hub height.

4. Measure distance (B) between tire beads at rear of tire. Measure at hub height.

5. Front distance (A) should be 2 to 9 mm (3/32 to 3/8 in.) less than rear distance (B). If not, adjust tie rod length.


M57588

6. Loosen nut (C) on each tie rod.

7. Turn tie rod (D) until toe-in distance is 2 to 9 mm (3/32 to 3/8 in.).

8. Tighten tie rod nuts.

9. Check steering. Ball joints must move freely.

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.

Cleaning and Repairing Metal Surfaces

Cleaning:

Follow automotive practices to care for your vehicle painted metal surfaces. Use a high-quality automotive wax regularly to maintain the factory look of your vehicle’s painted surfaces.

Repairing Minor Scratches (surface scratch):

1. Clean area to be repaired thoroughly.

IMPORTANT: Avoid damage! Do not use rubbing compound on painted surfaces.


2. Use automotive polishing compound to remove surface scratches.

3. Apply wax to entire surface.

Repairing Deep Scratches (bare metal or primer showing):

1. Clean area to be repaired with rubbing alcohol or mineral spirits.

2. Use paint stick with factory-matched colors available from your authorized dealer to fill scratches. Follow directions included on paint stick for use and for drying.

3. Smooth out surface using an automotive polishing compound. Do not use power buffer.

4. Apply wax to surface.
