Check the front-to-rear blade level any time you install
the mower. If the front of the mower is more than
7.9 mm (5/16 inch) lower than the rear of the mower,
adjust the blade level.

Park the machine on a level surface, disengage
the blade-control switch (PTO), and move the
motion-control levers outward to the P
position.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3.
Set the height of cut to 76 mm (3 inches).
4.
Carefully rotate the blades so they are facing
front to rear
(Figure

Measure from the tip of the front blade to the
flat surface and the tip of the rear blade to the
flat surface

Note:
If the front blade tip is not 1.6 to 7.9 mm
(1/16 to 5/16 inch) lower than the rear blade
tip, continue to the
