Fill the transmission with oil, Check for the proper oil level.

John Deere 1025R, 1023E Front Axle

Check Front Axle Oil Level

To ensure accurate dipstick reading, allow oil to settle for one hour before checking. Repeat oil level check after several hours of operation. Park machine safely on level surface. Allow machine to cool down for at least one hour. Dirt and debris cause damage to the transaxle. Clean area around opening before removing dipstick. Loosen and remove dipstick located on right side of front axle. Wipe dipstick clean with a rag. Install dipstick but do not tighten. Allow dipstick to rest on top of threads. Remove dipstick. Oil level should be between high and low levels on dipstick. If oil level is low: Add recommended oil through dipstick fill opening until oil level is correct. Install and tighten dipstick.

Change Front Axle Oil

Warm front axle oil by operating machine. Park machine safely. Position drain pan under the differential drain plug. Remove the differential drain plug and allow oil to drain. Position drain pan under each front axle drain plug. Remove both drain plugs and allow oil to drain. Install and tighten both drain plugs after all oil has drained. Remove dipstick on the right side of the front axle and vent plug. Add approximately 2.8 L (3.0 qt) of recommended oil through dipstick fill opening until oil level is correct. Install and tighten the dipstick. To ensure accurate dipstick reading, allow oil to settle for 1 hour before checking. Repeat oil level check after several hours of operation. Check front axle oil level.

Lubricate MFWD Driveshaft

Loosen hose clamp and remove front MFWD shield from housing. Lubricate front MFWD driveshaft grease fitting and rear MFWD driveshaft grease fitting with John Deere multi-purpose grease. Install MFWD shield on housing and tighten hose clamp.

JD 1025R, 1023E - Remove and Install Wheels

Front Wheel Removal

Loosen lug bolts slightly before raising front axle. Raise front of machine and lower onto support stands so that front axle supports machine. If the front wheels are being removed to perform work on the front axles, lower machine onto suitable stands that support the machine by the frame. Remove lug bolts and wheel.

Front Wheel Installation

Install wheels onto axle, insert lug bolts, and lightly tighten bolts. Raise front of machine, remove support stands and lower machine to floor. Tighten wheel bolts alternately to specification. Wheel Bolt Torque - 95 Nm (70 lb-ft)

Rear Wheel Removal

Loosen lug bolts slightly before raising machine rear axle. Raise rear of machine and lower onto support stands so that rear axle supports machine. Remove lug bolts and wheel.

Rear Wheel Installation

Install wheels onto axle, insert lug bolts, and lightly tighten bolts. Raise rear of machine, remove support stands and lower machine to floor. Tighten wheel bolts alternately to specification. Wheel Bolt Torque - 95 Nm (70 lb·ft).

John Deere 1025R, 1023E - Select Front Tire Rolling Direction

JD 1025R, 1023E tractor is equipped with directional type tires (such as bar tires) and have directional arrows on the tire sidewall. Install the tires with the directional arrow pointing in the direction of travel. To increase tire life when the tractor is used mainly for loader operations and improve traction while backing out of dirt piles, reverse the lug direction. If the tractor is manly used for loader operations, lug direction may be reversed on the MFWD axle for improved tire wear and increased traction. Change the tire rolling direction by moving the wheel from one side of the machine to the other. Install the wheel with the valve stem facing outwards.

John Deere 1025R, 1023E - Differential Lock and PTO Driveshaft

Differential Lock (Traction Assist)

The differential lock is used to provide better traction when the rear wheels start to slip. With the differential lock engaged, the right and left side rear axles are locked together and both rear wheels turn at equal speeds for maximum traction. Reduce speed and allow the drive wheels to rotate at the same speed before engaging or disengaging the traction assist. Disengage the traction assist when driving on asphalt or concrete. Use the traction assist only when necessary for improved ground engagement. The turning radius is increased when the differential lock is engaged.

Engage Differential Lock

Stop or slow the machine movement. The differential lock remains engaged as long as the rear wheel slippage occurs. If the tires slip and regain traction repeatedly, hold down the differential lock pedal so differential lock remains engaged. To engage the differential lock, push down on the differential lock pedal.

Disengage Differential Lock

Remove foot from the differential lock pedal. Rear wheel slippage keeps differential lock engaged. Lock automatically disengages when traction equalizes. If lock does not disengage when removing foot from pedal, depress brake pedal to equalize traction, then release.

John Deere 1025R, 1023E - Check PTO Driveshaft Length

Check PTO driveshaft movement before operating implement. Park machine safely. Install driveshaft on implement. Attach implement to tractor. Do not install the driveshaft on tractor. Check the fully shortened position of the driveshaft. Push the driveshaft in to its shortest length by hand. Check the area where the outer tube shield meets the shield bell. If the outer tube shield does not touch the shield bell, make a mark on the inner tube where the outer tube shield ends. Install driveshaft on tractor and adjust the center link to level the implement for operating while in lowered position.

Have an observer stand a safe distance from the implement to tell you when the driveshaft is fully shortened. Set the tractor at low idle and raise the implement. Stop raising the implement when the outer tube shield reaches the mark on the inner tube, or the outer tube shield touches the shield bell. If the implement is fully raised and the driveshaft does not reach the fully shortened position, with either the outer tube shield at the mark or touching the bell shield, the driveshaft is ready for operation. If the driveshaft reaches the fully shortened position before the implement is fully raised, the driveshaft requires shortening.

Shortening the PTO Driveshaft

Remove 25 mm (1 in) from the ends of the driveshaft and the ends of the shield tubes. Check driveshaft length again and shorten further if needed.
