Prior Going To The Field
Detracker Placement
Refer to Figure 5
Adjust detracker frames to approximate location as
shown in Figure 5 to clear other parts on machine. Adjust
coulter assemblies to cover tire tracks.
Detracker Adjustments
Refer to Figure 6
Spring Adjustment
12. Coulters springs are preset at 10”, giving the
coulters an initial operating force of 400 pounds.
This setting is adequate for many no-till conditions.
For lighter no-till conditions where rocks or other
obstructions are a problem, you can lengthen the
springs to protect the coulters from impact.
Spring Length
Force
10.25” (26.04cm) 300lbs (136kg)
10” (25.4cm) 400lbs (181kg)
9.75” (24.77cm) 525lbs (238kg)
Note: Setting the coulter spring length shorter than 9.75”
may contribute to premature failure of parts and
voids the warranty.
Detracter Height Adjustment
13. The initial height of the detracker coulter assemblies
is 1 1/2” - 2” deeper than the machine gangs. To
adjust the height, loosen the set screws on the
clamp shanks and slide the shank up or down to
20
21
the desired height, then re-tighten set screws.
Note: May need to adjust coulter height for different field
conditions.
14. Be sure all bolts are tightened to specs, See
“Torque Value Chart” on page 6.
15. This completes the setup.
