Adjusting Side-to-Side Level

The blade should be level within 3/16 inch (5.0mm).
The height of cut bracket on the left side of the chassis
can be adjusted up and down to level the blade.
Loosen the two cap screws holding the bracket to the
frame rail to do this (Figure 32).

Adjusting Front-to-Rear Pitch

The blade should be 1/4-5/8 inch (6-16mm) lower at
the front of the mower than at the rear. This
measurement can be between 1/8 inch (3.1mm) and
5/8 inch (15.7mm) low in front. If the difference is out of
this range, the mower suspension is either worn or
bent. Straighten or replace as needed.

Adjusting Blade Tracking

The blade should be a minimum of 1/8 inch (3.1mm)
above the bottom of the housing. If out of tolerance,
insert a washer or other shim between the spindle
housing and mower housing (Figure 33). Re-measure
the blade side to side. If now correct, remove the
spindle housing bolt and re-install through the housing,
shim, and spindle. Note that the blade tip will move
more than the thickness of the shim.

XL Series Front Engine Rider

The XL Series Front Engine Rider has been offered
with three cutting units. A 32-inch (81.3cm) single
blade, a 38-inch (96.5cm) twin blade, and a 44-inch
(111.7cm) three blade mowing deck (Figure 34).
Side-to-side adjustment procedures are the same for
all three mowing decks. However, the front-to-rear
pitch varies between the three.
On the cutting units with multiple blades, the blades
must line up with each other in the same cutting plane.
This is considered part of blade tracking and is covered
under that heading.
