4. Measure the length of the rear trunion rod (Fig. 40). If
the rod length is not 11-1/2 inch (29.2 cm), remove the
clevis pin and cotter pin from the end of the rod
(Fig. 40), loosen the jam nut, and turn the yoke until the
11-1/2 inch (29.3 cm) dimension is obtained. Then
secure the yoke with the clevis pin and cotter pin.
Repeat this procedure on the opposite side of the
mower.

5. Set the height-of-cut at 3 inch (76 mm) and carefully
rotate the blades so they are facing front to rear
(Fig. 41).
6. Measure between the tip of the front blade (Fig. 41) 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. 42). 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. 41).
10. When the front-to-rear blade slope is correct, tighten the
jam nuts (Fig. 40 and 42).
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.
