CUTTING HEIGHT ADJUSTMENT
Mower cutting height may be raised, lowered and maintained using tractor hydraulics and lift chains. Optional caster wheels may be used to maintain cutting height. Proper lift chain adjustment is essential for both cutting height control methods.
NOTICE
■Tractor upper stop of hydraulic control lever must be set to prevent any part of mower from coming closer than 1/4" to the tractor or mower lift bracket when mower is in the fully raised position.

Figure 1. Cutting Height Adjustment
Attach lift angle (9) to tractor upper lift rock shaft arm. Run a 3/8" hex nut (29) halfway down eyebolt (28), then assemble to lift angle with a second 3/8" hex nut. Do not tighten hex nuts until final adjustments are made.
Hook chain (1) into slotted lift lug (10). Slip slotted lift lug over the end of open-end eye bolt. Repeat for opposite side, making sure chains are untwisted and that the same chain link is inserted into the slotted lift lug.
Slowly raise mower to determine if correct chain link was selected which allows for sufficient lift. Once the correct chain link is selected, raise mower until no com- ponent is closer than 1/4" to tractor. Set the upper stop of the tractor hydraulic control lever at this point.
With the lift height set, side to side leveling adjustment can be made by adjusting the 3/8" hex nuts on each lift angle (9). Tighten hex nuts when adjustment is com- plete.
Failure to properly adjust hydraulic control lever stops may result in damage to tractor and mower.
