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

1. Check tires for damage.


M33418

2. Check tire pressure with an accurate gauge.

3. Adjust air pressure, if necessary:

Tire Size

Pressure

kPa (psi) (bar)

20 x 10 - 8

82.7 (12) (.827)

20 x 10 - 10

151.7 (22) (1.50)


Tighten Wheel Bolts


M56242

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

Adjusting Park Brake


M79100

1. To adjust park brake tension, place park brake (A) in the disengaged position.


M79109

2. Tighten the yoke (B) so the brake pads just begin to drag on the brake rotor. Then back off one revolution.

3. When all yoke adjustments have been used, back off the yoke so the threads on the rod (C) are flush with the yoke.

IMPORTANT: Avoid damage! Do not loosen top nut (G) until spring (H) is loose. If top nut is backed off too far, spacer on inside of spring may jump out of hole in spring bracket and bind up brake when top nut is tightened.



M79108

4. Loosen top nut (G) approximately 1/4 inch.

5. Remove hairpin clip from end of “J” rod (E).

6. While holding caliper arm with spring assembly, up as far as possible adjust “J” rod until end of rod aligns with hole in brake lever arm (F).

7. Reassemble “J” rod, washer, and hairpin clip (E).

8. Tighten top nut (G), while holding bottom nut (D), until it contacts spacer. Torque to 10 N•m (7 lb-ft).

9. Engage the brake and repeat on opposite side.

Cleaning Equipment Properly After Use

Following are general guidelines for the daily cleaning of John Deere Golf & Turf Equipment:

1. Lower attachments to the ground.

2. Disengage all power and stop the engine.

3. Move hydraulic lift levers back and forth to relieve pressure.

4. Lock park brake and remove the key.

c CAUTION: Avoid injury! Reduce compressed air to less than 210 kPa (30 psi) when using for cleaning purposes. Clear area of bystanders, guard against flying chips, and wear personal protection equipment including eye protection.

IMPORTANT: Avoid damage!

• Compressed air should be used to clean all radiators and air screen. Do not use water when cleaning these areas.

• Do not use water to wash under hood or under seat area or where electrical components are located. Use compressed air and blow debris away. Water in electrical connections may create electrical problems.

• Do not direct high pressure water at the reel motor seals. Water may be drawn into bearings as they cool.


5. Blow debris from radiators, air screens, under the hood and seat area using compressed air.

6. Wash exterior of machine, foot platform area and reels using high volume, low pressure water.

7. Perform grease maintenance on the reels after washing to purge any moisture from system.

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.

Raising Hood

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


M87064

2. Turn button (A) to unlock hood and pull hood up.

NOTE: Hinged cover plates (C) on each side of hood, tilt forward independently to provide additional access and service capability.

3. Lift off air plenum (B) to expose the top of engine.
