Harrow Adjustment
Figure 1 shows one harrow setting that has been successful in
no- and minimum-till conditions. Because of different soil mois-
ture, trash levels and trash types, you may need to reposition the
tube frame or tines.
Figure 1
Harrow Tines
To adjust frame tube, refer to Figure 2. Loosen four hex nuts (1)
on u-bolts and rotate frame tube (2).
To adjust tines, loosen four 1/2-inch hex nuts (3) on 1/2-inch u-
bolts (4) on support bar (5). Rotate tine tubes (6) so tines (7) are
against stop bushings (8) and are at desired angle. Retighten
hex nuts on u-bolts.
