John Deere 3032E, 3036E, 3038E Front Wheel Drive
Differential Lock (Traction Assist)
The John Deere 3032E, 3036E,
3038E differential lock is used to provide better traction when the rear
wheels start to slip. Engaging the differential lock will lock the right
and left side rear axles together and cause both rear wheels to turn at
equal speeds for maximum traction. Using the traction assist function
improperly can damage the transaxle: Reduce speed and allow drive wheels
to rotate at same speed before engaging or disengaging traction assist.
Disengage traction assist when driving on dry asphalt or concrete. Use
traction assist only when necessary for improved ground engagement.
Turning radius is increased when the differential lock is engaged.
Engaging Differential Lock - Stop or slow machine movement. Depress
pedal 20 - 25mm (3/4 - 1 in.) to operate differential lock. Disengaging
Differential Lock - Rear wheel slippage will keep differential lock
engaged. Lock will automatically disengage when traction equalizes.
Mechanical Front Wheel Drive (MFWD)
JD 3032E, 3036E, 3038E
Mechanical front wheel drive (MFWD) enables the powertrain to drive both
front and rear axles for improved traction on difficult ground
conditions and provides 4-wheel braking. MFWD can be engaged and
disengaged on-the-go with light loads and on low traction surfaces. Use
extra caution when driving on slopes. To increase traction and provide
four-wheel braking, engage mechanical front wheel drive (MFWD) when
driving on slopes. Be aware that MFWD can improve access to dangerously
sloped terrain, thereby increasing the possibility of tipover. To
improve braking on sloped, icy, wet, or graveled surfaces, engage the
MFWD. Add ballast to the tractor and travel at a reduced speed to avoid
skidding and loss of steering control. Always disengage MFWD when
driving on a paved surface. Put the transmission levers in neutral to
move the machine when the engine is not running.
Pull up on MFWD lever to engage MFWD. It may be necessary to reduce
engine load to disengage front wheel drive. Push down MFWD lever to
disengage MFWD. Tips for Operating MFWD: Maintain front tire pressure at
maximum allowable level to ensure proper tire performance in all field
conditions. Engage MFWD to provide four-wheel braking. Disengage MFWD
when driving machine to or from work site to increase front tire life.
John Deere 3032E, 3036E, 3038E Tractor Wheels and Tires
Checking Wheel Bolts and Hardware
When John Deere 3032E, 3036E, 3038E
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 - Tighten front wheel bolts
alternately to 140 Nm (103 lb-ft). Rear Wheel Bolts - Tighten rear wheel
bolts alternately to 140 Nm (103 lb-ft). Removing and Installing Wheels
- Use a safe lifting device and support machine securely on jack stands.
Block front and rear of wheel not raised to prevent machine movement.
Wheel can be heavy or difficult to handle when removing.
Front Wheel Removal and Installation
Loosen lug nuts slightly before
raising front axle. Raise front of machine and lower onto support stands
so that machine is supported by front axle. Remove lug bolts and wheel.
If the front wheels are being removed to perform work on the front
axles, lower machine onto suitable stands that will support the machine
by the frame. Install wheels onto axle, insert lug bolts and lightly
tighten bolts. Raise front of machine, remove support stands and lower
machine to floor. Tighten lug bolts to 140 Nm (103 lb-ft). Rear Wheel
Removal and Installation - Loosen lug bolts slightly before raising
machine rear axle. Raise rear of machine and lower onto support stands
so that machine is supported by rear axle. Remove lug bolts and wheel.
Install wheels onto axle, insert lug bolts and lightly tighten bolts.
Raise rear of machine, remove support stands and lower machine to floor.
Tighten lug bolts to 140 Nm (103 lb-ft).
Checking Tire Pressure
Check tires for damage. Check tire pressure with an accurate gauge. Add or
remove air, if necessary Selecting Front Tire Rolling Direction - JD
3032E, 3036E, 3038E tractors equipped with directional type tires (such as bar
tires) have directional arrows located on the tire sidewall. Under most
conditions, tires should be installed with the directional arrow
pointing in the direction of travel. If machine 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 machine to the other to change tire rolling direction.
Changing Wheel Spacing and Tread Width
In special cases, front tires
can be set to the wide position; however, the wide position cannot be
used for loader operation. Using the wide position during loader
operation will reduce front axle life. Rear tires can be mounted in one
position only. Always make sure tires rotate in proper direction. Arrows
on sidewall should point in direction of forward rotation. Rear Tire
Tread Width Dimensions - 15.00-19.5 R4 GA - 1,08 m (42.8 in.),
41x14.00-20 R3 GA - 1,10 m (43.5 in.), 11.2-24 R1 GA - 1,15 m (45.2
in.). Front Tire Tread Width Dimensions - 25x8.50-14 4PR R4 GA (Narrow)
- 1,08 m (42.8 in.), 27x8.50-15 4PR R3 GA (Narrow) - 1,06 m (41.7 in.),
7.00-14 4PR R1 GA (Narrow) - 1,06 m (41.7 in.), 25x8.50-14 4PR R4 GA
(Wide) - 1,25 m (49.4 in.), 27x8.50-15 4PR R3 GA (Wide) - 1,28 m (50.5
in.), 7.00-14 4PR R1 GA (Wide) - 1,28 m (50.3 in.).
Checking and Adjusting Toe-In
Stop machine on a firm, level surface. Disengage MFWD if equipped. Turn steering wheel so front wheels are pointing straight ahead. Park machine safely. 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. Mark the center line of each tire at hub height and to the front of the axle using chalk. Measure and record distance between the center lines of each tire. Drive machine forward or rearward slightly until chalk mark moves 180 to the rear of the axle. Park machine safely. Measure and record distance again between the chalk marks. Determine the difference between front and rear measurements. Distance may be larger at front or rear measurement but should not exceed 3 mm (1/8 in.). Adjust toe-in if necessary. Loosen jam nuts on both ball joints. Rotate tie rod 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 1.5 mm (1/16 in.). Tighten jam nuts to 120 Nm (88 lb-ft). Check toe-in setting. Repeat procedure if further adjustment is required.
