Service Dealer’s Guide to Great Quality of Cut 4 - 9

Checking and Adjusting the Blade Level

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.
