5. Set the height-of-cut at 3 inch (76 mm) and carefully
rotate the blades so they are facing front to rear
(Fig. 40).
6. Measure between the tip of the front blade (Fig. 40)
and the tip of the rear blade to the flat surface. If the
front blade tip is not 1/16–5/16 inch (1.6–7.9 mm)
lower than the rear blade tip, adjust the front trunion
rods.

8. Rotate the yokes on the rods to change the adjustment
(Fig. 41). To raise the front of the mower, tighten the
yokes (shorten the rods). To lower the front of the
mower, loosen the yokes (lengthen the rods).
9. After adjusting both trunion rod yokes evenly, secure
the yokes with the hairpin cotters. Check the
front-to-rear level again. Continue adjusting the yokes
until the front blade tip is 1/16–5/16 inch
(1.6–7.9 mm) lower than the rear blade tip (Fig. 40).
10. When the front-to-rear blade slope is correct, tighten
the jam nuts (Fig. 39 and 41).
11. Recheck the side-to-side level of the mower; refer to
Leveling the Mower from Side-to-Side, page 30.
12. Check the height of the anti-scalp rollers; refer to
Adjusting the Anti-Scalp Rollers, page 17.
