Front-To-Rear Blade Slope - Toro 71199 Operator's Manual

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 Checking the Tire Pressure, page 25. If the front of the
mower is more than 5/8 in. (16 mm) 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 PTO,
shift into neutral, set the parking brake, stop the engine,
and remove the ignition key.
2. Pull the wire off of 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 32.
4. Move the height-of-cut lever 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. 46). If the front of the
mower is more than 5/8 in. (16 mm) lower than the rear
of the mower, an adjustment is required; refer to
steps 6–10.

6. Measure the length of the rod extending out of the front
of the adjusting block on the sides of the chassis
(Fig. 47). If the rod length is not 5/8 in. (16 mm),
remove the hairpin cotter and washer from the end of
the rod (Fig. 47), and turn the rod until the 5/8 in.
(16 mm) dimension is obtained. Then install the end of
the rod into the hole in the mower mount and secure it
in place with the washer and hairpin cotter. Repeat this
procedure on the opposite side of the mower.

7. Check the front-to-rear slope again. If the front of the
mower is more than 5/8 in. (16 mm) lower than the rear
of the mower, proceed to step 8 for the 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. 48).
9. Using a 1 in. 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. 48). Rotate the slope
adjusting nut until the front of the mower is 1/4 to
5/8 in. (6 to 16 mm) lower than the rear of the mower.
10. Slowly rotate the right side slope adjusting nut until
both adjusting nuts are in the same position.
Important
If the slope adjustment does not stay in
position after you adjust it, tighten the center bolt and
locknut and repeat step 9.
