Adjusting the Front-to-Rear
Blade Slope
Check the front-to-rear blade slope any time you install the
mower. Before you check the slope, set the air pressure in
the front and rear tires to the recommended inflation; refer
to the tractor Operator’s Manual for the correct tire
pressure.
1. Park the machine on a level surface, disengage the
blade control (PTO), set the parking brake, and turn the
ignition key to Off to stop the engine. Remove the key.
2. Disconnect the wire from the spark plug.
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 on page 7.
4. Measure the length of the rod extending out of the front
of the adjusting block on the sides of the chassis
(Fig. 13).

(Fig. 13) and turn the rod until you obtain the 5/8 in.
(16 mm) dimension.
5. Install the end of the rod into the hole in the mower
mount and secure it with the washer and hairpin cotter.
6. Repeat steps 4 and 5 on the opposite side of the mower.
7. Move the height-of-cut lever into position C.
8. Carefully rotate the blades so that they are facing front
to rear.
9. Check the front-to-rear slope by measuring between the
bottom of the mower (front center and rear center) and
the flat surface (Fig. 14).
If the front blade tip is not within a range of 0 to 5/16
inches (0 to 8 mm) lower than the rear, adjust the
front-to-rear blade slope (steps 10 through 13);
otherwise, skip to step 14.

11. Rotate the locknuts on the eyebolts to change the
adjustment (Fig. 15). To raise the front of the mower,
tighten the eyebolt locknuts. To lower the front of the
mower, loosen the eyebolt locknuts.
12. After adjusting both eyebolt locknuts evenly, check the
front-to-rear slope again. Continue adjusting the
eyebolts until the front blade tip is 0 to 5/16 in. (0 to
8 mm) lower than the rear blade tip.
