Selecting Front Tire Rolling Direction

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

M99214

Tractors equipped with directional type tires (such as bar tires) have directional arrows (A) located on the tire sidewall. Under most conditions, tires should be installed with the directional arrow pointing in the direction of travel.

If tractor is mainly used for loader operations, lug direction may be reversed to increase tire life and improve traction while backing out of dirt piles.

Move wheel from one side of tractor to the other.

Changing Wheel Spacing and Tread Width

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


IMPORTANT: Avoid damage! Always make sure tires rotate in proper direction. Arrows on sidewall should point in direction of forward rotation. Tires must have at least 25 mm (1 in.) clearance with fenders.

The front and rear wheels can be mounted in WIDE or NARROW positions to increase or decrease wheel spacing. To provide best stability, operate tractor with rear wheels mounted in the wide tread position whenever possible.

Front Wheel Positions:

· WIDE POSITION - Install wheel with valve stem to the inside.

· NARROW POSITION - Install wheel with valve stem to the outside.

Rear Wheel Positions:

· WIDE POSITION - Install wheel with valve stem to the outside.

· NARROW POSITION - Install wheel with valve stem to the inside.

The mounting flanges on the rear rims are closer to one edge of the rim than the other, allowing the inner wheels to be mounted in different positions. By changing this position of the wheel on the rim, up to eight different tread widths can be achieved on some tractors.

Various positions cannot be used because the tires would strike the fenders. Certain other positions may result in equal tread widths.

The front wheel spacing can be adjusted to eight different tread widths by reversing the front wheels and by extending the front axle.

Tread width is measured from centerline-to-centerline of each tire.

Mounting Guidelines

MX4802

· To keep tire rotation in the proper direction when wheels are reversed without demounting rims, move each wheel to the opposite side of the tractor.

· Rims can be attached to either side of wheel.

· Mounting flanges on rim are closer to one edge of rim.

· Tread width can be changed by turning the wider side in or out.

· To keep tire rotation in the proper direction, move each rim to opposite side of tractor, rather than turning the rims around.

· Dished wheels can be reversed.

· Tighten all bolts to specifications.

Adjusting Front Axle Width (2WD Models)

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

Adjust front axle width as needed to achieve desired front tire tread width.

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


IMPORTANT: Avoid damage! Do not place lifting device under engine oil pan.

2. Raise front of tractor with a safe lifting device. Support with blocks and/or jack stands.

M63659

3. Loosen tie rod tube jam nuts (A) and bolts (B) on each side of the front axle. DO NOT remove bolts.

4. Remove two hex lock nuts (C) and two axle bolts (D) from each side of the front axle.

NOTE: Tie rod and power steering cylinder will self-align to the proper width position as axle is extended.

5. Pull outward on each wheel assembly to extend the inner axle channel to the desired width. Holes must align with holes in inner axle channel.

6. Install axle bolts (D) and lock nuts (C). Tighten bolts to 260 N·m (190 lb-ft).


IMPORTANT: Avoid damage! Prevent damage to the tie rod tubes. Do not overtighten hardware.

7. Tighten bolts (B) to 79-98 N·m (58-72 lb-ft).

8. Tighten jam nuts.

9. Lower tractor to ground.

10. Check toe-in setting. Adjust if needed.

Checking and Adjusting Toe-In

1. Stop tractor on a firm, level surface.

2. Disengage MFWD if equipped.

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

NOTE: If front axle is equipped with bar tires, use an outside bar of each tire or an inside bar of each tire for marking the center line.

MX4797a, MX4803

Picture Note: Top photo shows a MFWD model tractor. Bottom photo shows a 2WD model tractor.

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

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

3. Drive tractor 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:

· 2WD Tractors - Distance (A) at front of tires should be 3 - 6 mm (1/8 - 1/4 in.) less than distance at rear of tires. If not, adjust toe-in.

· MFWD Tractors - 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 (MFWD Models)

MX4797a, MX4801a

1. Loosen jam nuts (A)

2. Rotate tie rod (B) clockwise or counterclockwise to adjust the amount of "toe". 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.

Adjusting Toe-In (2WD Models)

MIF

1. Loosen jam nut (A) on each side of the front axle.

2. Rotate adjuster (B) while holding hex nut (C) to lengthen or shorten each tie rod. Adjust each tie rod equally 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.

Tightening Wheel Hardware

c CAUTION: Avoid injury! To prevent possible tractor roll over, never operate tractor with a loose rim, hub, or axle.

When tractor 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

MX4796

· Tighten front wheel disk-to-flange bolts (A) to 155 N·m (114 lb-ft).

Rear Wheel Bolts

MX4794

· Tighten rear wheel disk-to-flange bolts (B) to 155 N·m (114 lb-ft).

· Tighten rear wheel rim-to-disk bolts (C) to 240 N·m (177 lb-ft).

Tightening Front Axle Hardware (2WD Models)

M63659

· Tighten front axle bolts (A) to 260 N·m (190 lb-ft).

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.

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 John Deere 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.
