the selected height-of-cut; refer to Adjusting the Two

Checking the Mower Level
For optimum efficiency, check the level of the mower after
installation and periodically, to ensure that the blades are
1/8 in. (3 mm) lower in the front than in the rear.
Check and adjust the mower on a flat, level surface,
preferably concrete. Before checking the mower level, set
the air pressure in the front and rear tires as specified in the
tractor Operator's Manual. Place the mower height-of-cut
lever to the middle cut position. Ensure that the two
adjustable front wheels are off of the ground.
1. Disengage the PTO, set the parking brake, lower the
attachment lift, stop the engine, and remove the ignition
key.
2. Carefully rotate one of the blades so it is oriented front
to rear (Fig. 18).
