6. Loosen bottom chain bolt in slot at rear of deck.
Repeat for opposite side. (Fig. 42).
Note: Do not loosen front chain hardware.
7. Loosen front and rear locking nut on either side of
front swivel. Loosen until front chains are loose and
deck is supported by blocks. Repeat for opposite side.
(Fig. 42).
Note: When hardware is loose, deck will rotate the lift
handle up out of position.
8. When hardware is loosened, remaining tension in the
large support springs will tend to rotate the deck lift
handle up, out of the 1-1/2 position. Press down on
the rear deck support arm to firmly return the deck lift
handle to the 1-1/2 position (Fig. 42).
Note: Do not push on deck lift handle.
9. While continuing to press down on rear deck support
arm, take the slack out of the rear chain and tighten
hardware at the bottom (Fig. 42). Downward pressure

and that tension on all four chains are approximately
equal.
12. Raise deck to 3 inch height of cut and measure actual
height from blade tips to ground. Height of cut for the
front blade tips should be 3.00 .125 inches (76 mm
3 mm). Height of cut for rear blade tips should be
3.25 .125 inches (83 mm 3 mm). Readjust if needed.
Note: When checking blade tip heights make sure blades
are not bent and check blade pointing front to rear.
13. Install anti-scalp rollers for proper height-of-cut and
tighten securely. See Adjusting Anti-Scalp Rollers on
page 21.
14. Raise deck lift lever to the transport position (Fig. 41).
15. Adjust compression springs by turning the front spring
nuts so the distance between the two large washers is
10-1/4 (260 mm). Then tighten jam nut (Fig. 42).
Note: Make sure all hardware is tight.
Adjusting Push Arms
1. To adjust push arms, loosen jam nut and rotate ball
joint counterclockwise, one turn at a time. (Fig. 43).
