block. Tighten front locking nut. Repeat for opposite
side.
11. Recheck that blocks fit just snuggly under the mower
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 inch (76 3 mm).
Height of cut for rear blade tips should be
3.25 .125 in. (83 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 26.
14. Raise deck lift lever to the transport position (Fig. 65).
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. 66).
Note: Make sure all hardware is tight.
Adjusting the Push Arms
1. To adjust push arms, loosen jam nut and rotate ball
joint counterclockwise, one turn at a time. (Fig. 67).
2. Adjust each side the same amount. Each push arm
should have a nominal length of 15-5/16 inch
(389 mm) (Fig. 67).
Note: Increase tension by lengthening the push arms and
decrease tension by shortening push arms.
