Harrow Adjustment
1. The harrow on the rear of the machine can be set for
a variety of field conditions
(See Figure 4-6.) The
harrow that is set up according to the assembly
instructions for a working depth of 3 - 5 inches.
a. For deeper working depths, the harrow can be
adjusted up.
b. For running the implement at shallower depths,
the harrow can be lowered.
c. Spring tension can be increased by lowering the
rear mounting point of the two lower springs and
raising the front mounting point of the upper
spring an equal number of holes.
d. For more aggressive action by the harrow, the
angle of the harrow can be changed. By
removing the cotter pin and clevis pin, the harrow
teeth can be set at 45, 30, or 15 degrees. The
larger the angle, the more leveling and mixing of
the soil will occur. With the smaller angle, there is
less mixing of the soil, but the harrow has a
greater ability to allow trash to flow through
evenly.
