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 12 psi
(.85 kPa). If the front of the mower is not within a
range of 1/8”–3/8” (3.5mm–10.5mm) lower than the
rear of the mower, adjust the blade slope using the
following instructions:
1. Park the machine on a level surface, disengage
the blade control (PTO), shift into neutral, set
the parking brake, and turn the ignition key to
“OFF” to stop the engine.
2. Remove the key from the ignition switch and
pull the wire off the spark plug.
3. Check and adjust side-to-side blade level if you
have not checked the setting; refer to
Side-to-Side Mower Leveling, page 37.
4. Move the height-of-cut lever (deck lift) into the
“C” notch.
5. Check the front–to–rear blade slope by
measuring between the bottom of the mower
(front center and rear center) and the flat surface
(Fig. 44). If the front is not within a range of
1/8”–3/8” (3.5mm–10.5mm) lower than the rear,
an adjustment is required; refer to steps 6–10.

6. Measure the length of the rod extending out the
front of the adjusting block on the sides of the
chassis (Fig. 45). If the rod length is not 5/8”
(15.875 mm), remove the hair pin cotter and
washer from the end of the rod (Fig. 45), and
turn the rod until the 5/8” (15.875 mm)
dimension is obtained. Then install the end of
the rod into the hole in the mower mount and
secure in place with washer and hair pin cotter.
Repeat this procedure on the opposite side of the
mower.

7. Check the front-to-rear slope again. If the front
is not within a range of 1/8”–3/8” (3.5mm–
10.5mm) lower than the rear, proceed to step 8
for adjusting instructions. Otherwise, recheck the
side-to-side level to ensure it did not change.
8. Adjust the front-to-rear slope by rotating the
special slope adjusting nuts on both sides of the
mower pivot mount (Fig. 46).
9. Using a 1” wrench or socket slowly rotate the
left side slope adjusting nut down to raise the
front of the mower and up to lower it (Fig. 46).
Rotate the slope adjusting nut until the front of
the mower is 0” to 1/4” (0 mm to 6.5 mm) lower
than the rear of the mower.
