DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are

mechanical information and “Note” emphasizes
general information worthy of special attention.

than the rear blade tip, adjust the blade slope using
the following instructions:

the power take off (PTO), set the parking brake,
and turn the ignition key to “OFF” to stop the
engine. Remove the key.

3. Carefully rotate blades so they are facing front
and rear (Fig. 10).
4. Measure between the tip of the front blade
(Fig. 10) and the tip of the rear blade to the flat
surface. If the front blade tip is not 1/8–1/4”
(4–7 mm) lower than the rear blade tip adjust
rear adjustment link.
