ADJUSTING THE TRACTION DRIVE

FOR NEUTRAL (Fig. 49)

The machine must not creep when the traction pedal is

released. If it does creep, an adjustment is required.

1. Park the machine on a level surface, shut the engine off

and lower cutting units to the floor. Depress only the

right brake pedal and engage the parking brake.

2. Jack up the left side of the machine until front tire is off

the shop floor. Support the machine with the jack stands

to prevent it from falling accidentally.

Note: On 4-wheel drive models, the left rear tire must

also be off the shop floor.

3. Start the engine and allow it to run at low idle.

4. Adjust the jam nuts on the pump rod end to move the

pump control tube forward to eliminate forward creep or

rearward to eliminate rearward creep.

5. After wheel rotation ceases, tighten the jam nuts to

secure adjustment.

6. Stop the engine and release the right brake. Remove the

jack stands and lower the machine to the shop floor. Test

drive the machine to make sure it does not creep.

ADJUSTING THE CUTTING UNIT LIFT

RATE (Fig. 50)

The cutting unit lift circuit is equipped with an adjustable

valve to ensure the front cutting units raise and lower evenly.

Adjust the cutting units as follows:

1. Locate the valve under the seat.

2. Loosen the setscrew on the valve. Rotate the valve clock-

wise to slow down drop rate of the front outside cutting

units.

3. Verify lift rate adjustment by raising and lowering the

cutting units several times. Readjust as required.

4. After desired lift rate is attained, tighten the set screw to

lock adjustment.
