DRIVING ON SLOPES
WARNING: Do not operate on inclines with a slope in excess of 15 degrees (a rise of approximately
IMPORTANT: Always shift the transmission into the LOW speed range BEFORE beginning the climb or descent of any slope.
Operate the tractor up and down slopes, never across slopes. Do not drive so that the tractor may tip over sideways
Before operating the tractor on a slope, walk the slope to look for possible hazards such as rocks, mounds, stumps, or surface irregularities which could cause the tractor to be upset.
Back the tractor with attachment up the steepest portion of each slope you intend to work. If the tractor cannot negotiate the slope in reverse, the slope is too steep to be worked.
Avoid turns when driving on a slope. If a turn must be made, turn down the slope. Turning up a slope greatly increases the chance of a roll over.
Avoid stopping when driving up a slope. If it is necessary to stop while driving up a slope, start up smoothly and carefully to reduce the possibility of flipping the tractor over backward.
USING THE DIFFERENTIAL LOCK PEDAL
Depressing the differential lock pedal engages a mechanism in the transmission that locks the differential. This prevents the rear wheels from rotating independently of each other and provides constant power to both rear wheels when additional traction is needed.
IMPORTANT: Do not engage the differential lock when one of the rear wheels is rotating. Stop the wheel rotation and then engage the differential lock.

USING THE 4WD SHIFT LEVER
WARNING: The tractor should be stopped before engaging or disengag- ing the four wheel drive. Shifting while the tractor is in motion can cause dam- age to the transmission.
IMPORTANT: To prevent possible damage to the tractor transmission, engage the 4WD ONLY when additional traction is needed while operat- ing in loose soil or on slippery surfaces (e.g. mud, snow). Disengage the 4WD when operat- ing on firm surfaces or when operating at high speeds.
Use the 4WD shift lever to engage or disengage the drive to the front axle. Engage the 4WD to improve traction when operating the tractor on slippery surfaces (e.g. loose dirt, mud, snow).
•Stop the tractor; push the lever to the right of the slot to clear the shift gate; then shift forward to engage the four wheel drive.
•Stop the tractor; push the lever to the right of the slot to clear the gate; then shift the lever rearward to disengage the four wheel drive.
WARNING: When operating with the differential lock engaged, the tractor will be difficult to steer. Do not drive the tractor on roadways or at high speeds with the differential lock engaged.
•Fully depress and hold the differential lock pedal to engage the transmission differential lock. Release the pedal to disengage the differential lock. Refer to Figure 18.

NOTE: Because of the drive load on the internal engagement mechanism, releasing the differential lock pedal may not always disengage the differential lock. It may be necessary to slow the
