Adjusting the Mower

Adjusting the Height of Cut
The rear gauge wheels are adjusted in different hole
locations for 1–1/2—4–1/2" (4–11 cm) heights of cut.
1. Start the tractor, apply the parking brake, and
raise the deck. Get off the tractor. Pull the
height–of–cut lever out to disengage it from the
quadrant. Adjust the height of cut to the desired
level. Release the lever inward to lock into the
quadrant (Fig. 13).

Checking Mower Level
For optimum efficiency, the level of the mower
should be checked at the time of initial installation
and periodically as a check, to ensure that the blades
are 1/8" (3 mm) lower in the front than in the rear.
The mower must be checked and adjusted on a flat
level surface, preferably concrete. Before checking
the mower level, set the air pressure in the front and
rear tires to 12 psi (.85 kPa). Place the mower
height–of–cut lever to the middle cut position. Make
sure the two adjustable front wheels are off the
ground.
1. Disengage the power take off (PTO), set the
parking brake, lower the attachment lift, and turn
the ignition key to "STOP" to stop the engine.
Remove the key.
2. Carefully rotate one of the blades so it is facing
front and rear (Fig. 14).
