4-10 HARROW ADJUSTMENT
4-10.1 The harrow on the rear of the machine
can be set for a variety of field conditions.
The harrow is set up according to the as-
sembly 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 de-
grees (See Figure 4-4) . 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.
