Adjusting the Front-to-Rear
Blade Slope

Check the front-to-rear blade level any time you install the
mower. If the front of the mower is more than 5/16 in.
(7.9 mm) lower than the rear of the mower, adjust the blade
level using the following instructions:

1. Position the mower on a flat surface. Disengage the

PTO, set the parking brake, stop the engine, and remove
the key. Disconnect the spark plug wire(s) from the
spark plug(s).

2. Check the air pressure of all four tires. If needed, adjust

to the recommended inflation; refer to Tire Pressure,
page 29.

3. Check and adjust the side-to-side blade level if you

have not checked the setting; refer to Leveling the
Mower from Side-to-Side, page 29.

4. Measure the length of the rear trunion rod (Fig. 40). If

the rod length is not 11-1/2 in. (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 in. (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 in. (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 in. (1.6–7.9 mm) lower than
the rear blade tip, adjust the front trunion rods.

7. To adjust the front-to-rear blade slope, remove the

hairpin cotter from the front trunion yokes and loosen
the jam nuts (Fig. 42).

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 in. (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 29.

12. Check the height of the anti-scalp rollers; refer to

Adjusting the Anti-Scalp Rollers, page 16.
