Harrow Adjustment
Figure 3-5 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 3-5, then readjust as necessary.
Figure 3-5
Tine Angle For No-Till Drilling
To adjust the frame, refer to Figure 3-6. 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 3-6. 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. Re-tighten hex nuts on u-bolts.

Leaf Spring Adjustment
A leaf spring is located just ahead of the vertical pivot. See
Figure 3-7. The spring is designed to provide just enough
force to keep the hitch square and stable for turning at field
ends and to add stability for drilling in rough field condi-
tions. Proper leaf-spring adjustment is important for
smooth implement operation.
To adjust properly, refer to Figure 3-7. Square tongue with
transport frame and adjust 3/8-inch u-bolts (1) on each
side until leaf-spring rollers (2) just make contact with
roller pads (3) on transport frame. Make sure both right
and left sides are adjusted properly.

Marker Adjustments
Folding Speed
Adjust folding speed with hex adjustment screws on the
sequence-valve body. See Figure 3-8. There is one adjust-
ment screw for raising speed (1) and one for lowering
speed (2). Identify adjustment screws by markings
stamped in valve body.
With tractor idling at a normal operating speed, adjust
marker folding to a safe speed.Turn adjustment screws
clockwise to decrease folding speed and counterclock-
wise to increase folding speed. Excessive folding speed
could damage markers and void the warranty.
After adjusting the folding speed, tighten jam nuts on hex
adjustment screws to hold settings.
