Harrow Adjustment
Figure 3-11 shows a successful harrow position for no-till
conditions. Because of different soil moisture, trash levels
and trash types, you may need to reposition the tube
frame or tines. Initially position the frame and tines as
shown in Figure 3-11, then re-adjust as necessary.

Tine Angle For No-Till Drilling
To adjust the frame, refer to Figure 3-12. Loosen the four
hex nuts (1) on the u-bolts and rotate the frame tube (2) as
necessary.
To adjust the tines, refer to Figure 3-12. Loosen the four
1/2-inch hex nuts (3) on the 1/2-inch u-bolts (4) on the sup-
port bar (5). Rotate tine tubes (6) so the tines (7) are
against the stop bushings (8) and are angled back as nec-
essary. Retighten hex nuts on u-bolts.

Seed-Lok
The optional Seed-Lok firming wheels provide additional
seed-to-soil contact. The wheels are spring loaded and do
not require adjusting. In some wet and sticky conditions
the wheels may accumulate soil.
To lock up the firming wheels, hook one end of the chain in
the opener-body hole just above the wheel arm (1). Pull
the firming- wheel arm (2) up as high as possible and wrap
the chain around the arm. Hook the other end of the chain
in a link. Leave no slack in the chain; secure the wheel arm
in its highest position

Coulter Tines
Optional coulter tines are available. In high-residue fields,
the tines will help guide residue under the coulters and
openers to prevent plugging. Under normal conditions
these tines should not be needed. Remove or install the
tines as field condition warrant.
