Service Miscellaneous

Filling Fuel Tank


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.

Use diesel fuel Grade No. 1-D for cold air temperatures or Grade No. 2-D fuel for warm air temperatures. Diesel fuel must be cetane Number 40. A cetane number of 50 or more is preferred, especially for air temperatures below -20°C (-4°F) or elevations above 1500 m (5000 ft).

Number 2 or better diesel fuel is recommended. Using other fuel will result in increased fuel consumption and decreased engine performance.

Add John Deere fuel stabilizer to fuel before using it in your machine to prevent engine damage due to stale fuel. Follow directions on stabilizer container.

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.

· If using a funnel, make sure it is plastic and does not have a metal screen or filter.


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. · If using a funnel, make sure it is plastic and does not have a metal screen or filter.

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

2. Allow engine to cool several minutes before you add fuel.

3. Remove dirt, debris, and other trash from tank area.

MX13748

4. Remove fuel tank cap (A).

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

· If fuel is spilled, clean splash area (B).

6. Install fuel tank cap.

Tightening Wheel 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 disk-to-flange bolts alternately to 140 N·m (103 lb-ft).

Rear Wheel Bolts

Tighten rear wheel disk-to-flange bolts alternately to 140 N·m (103 lb-ft).

Checking and Adjusting Toe-In

1. Stop machine on a firm, level surface.

2. Disengage MFWD.

3. Turn steering wheel so front wheels are pointing straight ahead.

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

Checking Toe-In

1. Mark the center line of each tire at hub height and to the front of the axle using chalk.

MX13747

2. Measure distance (A) between the center lines of each tire. Record the measurement.

3. Drive machine forward or rearward slightly until chalk mark moves 180° to the rear of the axle.

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

5. Measure distance (A) again between the chalk marks. Record the measurement.

6. Determine the difference between front and rear measurements:

· Distance (A) may be larger at front or rear measurement but should not exceed 3 mm (1/8 in.). Adjust toe-in if necessary.

Adjusting Toe-In

MX13728

1. Loosen jam nuts (A) on both ends of tie rod.

2. Rotate tie rod (B) clockwise or counterclockwise to adjust the amount of toe-in. Adjust tie rod until toe-in measurement is within correct specification.

· Rotating threaded rod in 1/2 turn increments equals 1.5mm (1/16 in.).

3. Tighten jam nuts (A) to 120 N·m (88 lb-ft).

4. Check toe-in setting. Repeat procedure if further adjustment is required.

Selecting Tire Rolling Direction

c CAUTION: Avoid injury! Support machine securely on stands before removing a wheel.

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

Cleaning and Repairing Plastic Surfaces

Your John Deere dealer has the professional materials needed to properly remove surface scratches from any plastic surfaces, do not attempt to paint over marks or scratches in plastic parts.


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.
