ADJUSTING BLADE ANGLE
1. Loosen blade angle control locking lever F and

BLADE ANGLE (PITCH)
Under normal operating conditions, blade angle
is minimal (blade bottom is flat). In extremely
hard soil or when cutting with a dull blade, the
blade may want to ride out of the ground. It may
then help to adjust blade angle downward (see
Adjusting Blade Angle above). A short trial run
will indicate which is the best blade angle.
