Make sure the tension spring is attached to the
scalper assembly. The tensions spring should hold
the scalper shoe firmly to the ground
3.
The scalper knife (2) should be set so it is parallel
and straight with the edge of the shoe. The
recommended initial setting is 1/4 inch to 3/8 inch.
Run the machine in the field and get one row
adjusted to the desired setting. Once the first row
is adjusted, set the other row settings to match.

The depth of cut is adjusted by loosening the set
screws on the lower bearing and moving the two
jam nuts on the scalper shaft, sliding the shaft up
or down to attain the desired depth of cut, and then
re-tightening the jam nuts and set screws. The
distance from the bottom of the shoe to the lowest
point of the disc is generally between 3/4 to 1.0
inch. See Figure 23.
3.
The side-to-side angle of the blade can be
adjusted by loosening the two bolts on the top
bearing and moving the bearing in the slots on the
mounting plate. Re-tighten the bolts when finished.
The top bearing is positioned at the factory in the
center of the slots. See Figure 24

Run the machine in the field and get one row
adjusted to the desired setting. Once the first row
is adjusted, set the other row settings to match.
