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).

Capscrews bracket 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. 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. 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.
