Adjusting Front-To-Rear Pitch; 32-Inch (81.3Cm) Cutting Unit - Toro 20351 - High Wheel CARB Walk Power Mower Dealer Manual

Adjusting Front-to-Rear Pitch

Each of the three XL cutting units has a slightly
different specification for front-to-rear pitch and slight
variations in the adjustment process. Each cutting unit
is covered separately in one of the following
subsections.

32-inch (81.3cm) Cutting Unit

The blade on this model should be 1/4-5/8 inch
(6-16mm) lower in front. If the pitch is outside this
range adjustment is necessary (Figure 39).

1. Measure front center
1. Verify that the side-to-side level is correct. If not
adjust that first.
2. Measure the length of the rod extending out of the
front of the adjusting block on the sides of the
chassis (Figure 40). If the rod length is not
5/8 inch (16mm), remove the hairpin cotter and
washer from the end of the rod and turn the rod
until the 5/8 inch (16mm) 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 process on
the other side of the mower.

3. Check the front-to-rear pitch again. If the front is
still out of specification proceed to step 4.
Otherwise, recheck the side-to-side level to
ensure it did not change.
4. Adjust the front-to-rear pitch by rotating the
special pitch adjusting nuts on both sides of the
mower pivot mount (Figure 41).
