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. 16).

3. Measure the distance from the front tip of the blade
(Fig. 16) to the flat surface.
4. Carefully rotate the blade tip until it is in the rear
position and measure it in that position.
When the blade tip is in the front position, it should be
1/8 in. (3 mm) lower than when it is in the rear position.
5. If an adjustment is required, turn the adjusting nut
(Fig. 17) on the back of the mower. To raise the front of
the mower, turn the adjustment nut clockwise. To lower
the front of the mower, turn the nut counterclockwise.
