The single-marker system is equipped with a needle valve
in the hydraulic hose line at the rod end of the marker cyl-
inder as shown in Figure 3-18. 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 warran-
ty.

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 plug-
ging. Under normal conditions these tines should not be
needed. Remove or install the tines as field condition war-
rant.
Harrow Attachment Adjustment
Figure 3-19 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 3-19, then re-adjust as necessary.

To adjust the frame, refer to Figure 3-20. 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 3-20. 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. Remove or install the
wheels as field conditions warrant.
