Important: When set properly, the rear and
front rollers will contact the gauge bar and the
screw will be snug against the bedknife. This
ensures that the height-of-cut is identical at
both ends of the bedknife.
5. Tighten nuts to secure adjustment. Do not
overtighten nut. Tighten enough to remove play
from washer.
Use the following chart to determine which
bedknife is best suited for the desired height of cut.

6. To adjust the height of cut when fixed plate kits are
installed on the cutting units, proceed as follows:
• Remove the height of cut brackets and front
roller as described in Procedure 6 in the Set-Up
section.
• Install the cutting unit onto the traction unit
as described in the Traction Unit Operator's
Manual.
• Lower the cutting unit to the floor and measure
the distance from the floor to the top of the
bedknife, as shown in Figure 21

2. Upper mounting holes
• To attain the desired height of cut, adjust the
rear roller brackets to the desired height of cut
range by positioning the required amount of
spacers below the side plate mounting flange
per the HOC Chart. Refer to Adjusting the Rear
Roller.
Note: To achieve a less aggressive cut, mount
the cutting unit links in the number 1 position
or mount the links to the number 3 position for
a more aggressive cut.
