ADJUSTMENTS

PARK BRAKE:

1.Stop engine and remove key. Release park brake and measure the length of the spring. The distance between the washers on each end of the spring should be 2-7/8" (See Fig 2 ).

2.If adjustment is needed, loosen the nut below the spring. Then rotate nut to desired position so the proper distance between the washers is obtained. Check other side for proper adjustment.

3.Engage the brake lever and measure the distance between the trunnion pin and the collar welded to the brake rod. Distance should be 3/16" to 1/4" (See Fig 2 ).

4.If adjustment is needed, loosen the lock nut directly below the yoke. Using a wrench, rotate the rod by turning the double nuts using the nuts below the yoke and the nut you just loosened, to obtain the 3/16" to 1/4" distance. Tighten nut against yoke and check other side

for proper adjustment.

CUTTING HEIGHT:

1.Stop the mower and disengage the blades.

2.Raise the deck height lever to the transport position.

3.Remove the height adjustment pin and place it in the desired cutting height hole. Move deck height lever down onto the pin and mow. NOTE: anti-scalp rollers must be in the proper position for maximum deck floatation. See the decal on the front deck.

MOWER DECK LEVELING:

1.Position mower on a flat surface and stop engine.

2.Check the tire pressure of all four tires. Inflation should be 15 psi.

3.Place two 2x4’s on edge under the cutting deck from front to rear and lower the deck down onto the 2x4’s.

4.Adjust the four upper chain bolts to the center of the slot in the deck lift arms. NOTE: make sure deck lift blocks are tightly bolted to the frame (See Fig 3).

5.Return the deck height lever to the transport position (5" cutting height) and check the center to center distance of the swivels. Distance should be 19-1/2"

6.Check the distance between the washers on the deck lift springs. Distance should be 11-3/4" (See Fig 3).

7.Check chains for equal tension. If unequal, adjust upper chain bolt in slot.

8.Place deck in the 5" cutting height and measure from the cutting edge of the blade to a flat surface to check deck cutting height.
