11. Measure the length of the rod extending out of
the front of the adjusting block on the sides of the
chassis (Figure 47). If the rod length is not 3/4 inch
(19 mm), remove the hairpin cotter and washer from
the end of the rod (Figure 47) and turn the rod until
it extends out 3/4 inch (19 mm).

12. Install the end of the rod into the hole in the mower
mount and secure it in place with the washer and
hairpin cotter.
13. Repeat steps 11 and 12.@@@5 on the opposite side
of the mower.
14. Check the front-to-rear slope again. If the front
of the mower is more than 5/8 inch (16 mm)
lower than the rear of the mower, proceed to15.
Otherwise, check the side-to-side level to ensure it
did not change.

slope adjusting nuts on both sides of the mower
pivot mount (Figure 48).

16. Slowly rotate the left side slope adjusting nut down
to raise the front of the mower; rotate the nut up to
lower the front of the mower (Figure 48). Rotate
the slope adjusting nut until the front of the mower
is 1/4 to 5/8 inch (6 to 16 mm) lower than the rear
of the mower.
17. Slowly rotate the right side slope adjusting nut until
both adjusting nuts are in the same position.
Important: If the slope adjustment does not
stay in position after you adjust it, tighten the
center bolt and locknut and repeat step 16.
18. If you cannot get a 1/4 to 5/8 inch (6 to 16 mm)
front slope by rotating the slope adjusting nut, move
the mower pivot mount at the mower (Figure 49).
