ADJUSTING THE CUTTING UNIT LIFT

RATE (Fig. 45)

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 cut-

ting units several times. Readjust as required.

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

lock adjustment.

ADJUSTING THE SERVICE BRAKES

(Fig. 46)

Adjust the service brakes when there is more than 2.5 cm of

“free travel" of the brake pedal, or when the brakes do not work

effectively. Free travel is the distance the brake pedal moves

before braking resistance is felt.

1. Disengage the locking pin from the brake pedals so both

pedals work independently of each other.

2. To reduce free travel of brake pedals, tighten the brakes—

loosen the front nut on the threaded end of the brake cable.

Then tighten the rear nut to move the cable backward until

the brake pedals have 1.2–2.5 cm of free travel. Tighten

the front nuts after the brakes are adjusted correctly.

CHANGING PLANETARY GEAR DRIVE

OIL (Fig. 47)

Change the oil initially after 200 hours operation and every 800

hours, or yearly. Use high-quality SAE 85W-140 wt. gear lubri-

cation as replacement.

1. With the machine on a level surface, position the wheel so

the check/drain plug is at its lowest position.

2. Place the drain pan under the hub, remove the plug and

allow the oil to drain.

3. When all oil has been drained, position the wheel so the

plug hole is at three or nine o'clock position.
