Checking and Adjusting the Blade Level
5.
Using a 1-inch wrench or socket, slowly rotate the
left side adjusting nut down to raise the front of the
mower and up to lower it.
38-inch (96.5cm) Cutting Unit
The blade pitch for a 38-inch (96.5cm) mower is correct
when the blade in front is 1/8-3/8 inch (3.5-10.5mm)
lower in front than in the rear. If adjustment is
necessary proceed as follows.
6.
Slowly rotate the right side adjusting nut until both
nuts are in the same position.
Note: If the adjusting nut does not stay in position,
tighten the center bolt and locknut and repeat
steps 4 and 5.
1.
Verify that the mower is level side to side. If not
adjust that first.
2.
Measure the length of the rod extending out the
front of the adjusting block on the sides of the
chassis (Figure 43). 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 procedure
on the other side.
7.
If the 1/4 to 5/8 inch (6-16mm) pitch cannot be
achieved by rotating the adjusting nuts, move the
mower pivot mount at the front of the mower
housing (Figure 42).
Note: Some models only have one pair of holes to
select from. If the model you are working on only
has one hole and the front-to-rear pitch is still out
of specification, go back to the basics. Check the
tire pressure and inspect for a worn or damaged
chassis or suspension component.

Remove the shoulder bolts and lock nuts from the
mower. Installing the bolts in a higher hole will
lower the blade and using a lower hole will raise it.

3.
Recheck the front-to-rear pitch. If it is not within
specification, proceed to step 4.
9.
Repeat the front-to-rear adjustment steps 3-7.
10.
Once the front-to-rear pitch is within specification,
recheck the side-to-side adjustment (see
“Adjusting Side-to-Side Level—All Cutting Units”
on page 4-10).
11.
Once the front-to-rear pitch and side-to-side level
are within specification, continue by checking and
adjusting the blade tracking (see “Adjusting Blade
Tracking” on page 4-14).
