Refer to Figure 30
The single-marker system is equipped with a needle valve
in the hydraulic hose line at the rod end of the marker
cylinder. Turn the adjustment knob clockwise to decrease or
counterclockwise to increase folding speed. Adjust to a safe
speed. Excessive folding speed could damage the marker
and may void the warranty.
Coulter Tines
Optional coulter tines are available for the front-mounted
coulters. 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.
Harrow Attachment Adjustment
Refer to Figure 31
Figure 31 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, then
re-adjust as necessary.
Refer to Figure 32
To adjust the frame, loosen the four hex nuts (1) on the u-
bolts and rotate the frame tube (2) as necessary.
To adjust the tines, loosen the four 1/2-inch hex nuts (3) on
the 1/2-inch U-bolts (4) on the support bar (5). Rotate tine
tubes (6) so the tines (7) are against the stop bushings (8)
and are angled back as necessary. Tighten 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. Remove or
install the wheels as field conditions warrant.
