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 and allow to cool 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.

• Loosen fuel cap slowly to release pressure and to keep fuel from escaping around the cap.

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 the ROPS Hardware

c CAUTION: Avoid injury! To maintain operator protection and ROPS certification:

• Do not repair or revise the ROPS.

• Any alteration of the ROPS must be approved by the manufacturer.

1. Tighten four flange head bolts and four lock nuts (A) to 108 N•m (80 lb-ft).

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 (bar) (psi)

20 x 10 - 8

82.7 (0.827) (12)

20 x 10 - 10

151.7 (1.50) (22)


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

1. Park machine on a level surface.

2. Lock the park brake.

c CAUTION: Avoid injury! The machine can fall or slip from an unsafe lifting device or supports.

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

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

3. Lift machine with a suitable lifting device just high enough to allow drive wheels to turn.

4. Support machine with stable supports.

5. Operate lift control and allow cutting units to settle on ground.



6. To adjust park brake tension, place park brake (A) in the unlocked position as shown.
