GENERAL OPERATION
Pitch Adjustment
The angle of the cutter blade to the ground is called
the pitch. When the unit leaves the factory, it is set
for average cutting conditions, but can be changed
to suit various soil conditions.
When the ground is soft, it is desirable to adjust the
pitch so that the blade is as flat to the ground as
possible. When cutting in harder soil, the pitch may
have to be increased, (increase angle to the ground)
to maintain a proper cutting action, and to prevent
the cutting head from coming out of the ground.
Care must be taken when the pitch is changed, that
the relationship of the blade to the conveyor mat and
the roller is maintained. The front idler shaft of the
conveyor can be adjusted to assure the conveyor
mat does not interfere with the cutter blade. The
relationship of the roller to the cutter blade is
addressed in the roller adjustment section.
Adjusting the Pitch – 1570
The adjustment of the pitch is accommodated by a
set of three mounting holes for the pillow block
bearings on the pivot shaft and slots in the pillow
block bearings. The amount of pitch is determined
by the mounting holes used. The normal setting is in
the center set. The rear set of holes (minimum pitch)
is used for soft soil or peat. The front set of holes
(maximum pitch) is used for hard ground.
A periodic check should be made to assure the
mounting bolts have not loosened during operation
.

Adjusting the Pitch – 1576
The adjustment of the pitch is accommodated by a
series of four mounting holes, and a slot, to which
the pivot bracket is mounted. The amount of pitch is
setting is in the second hole (from the rear). The first
hole (minimum pitch) is used for soft soil or peat.
The third and fourth holes (maximum pitch) are used
for hard ground. Extra holes are used to provide
additional depth adjustment and will be addressed in
the sod thickness section,
A periodic check should be made to assure the
mounting bolts have not loosened during operation.
