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 as specified in the tractor operator's manual.
Place the mower height–of–cut lever to the middle
cut position. Make sure the two adjustable front
wheels are off the ground.
Adjusting Front–to–Rear Blade Cut
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 ignition key.
2. Carefully rotate one of the blades so it is facing
front and rear (Fig. 15).
3. Measure the distance from the front tip of the
blade (Fig. 15) to the flat surface. Then
carefully rotate the blade tip until it is in the rear
position. When the blade tip is in the front
position, it should be 1/8" (3 mm) lower than
when it is in the rear position.
