Vantage I Height Adjustment and Castering
Application Height Adjustment
Fertilizer release height is normally at or just above
the ground, and is controlled by three adjustments:
Refer to Figure 61
1. Tool bar height :
This affects coulter depth. The procedure for setting
tool bar height varies with hitch type.
2. Fertilizer arm height :
This affects arm height relative to the coulter.
This adjustment is primarily to compensate for blade
wear.
3. Coulter height :
This affects coulter height relative to the tool bar ,
and is normally not adjusted.
Factory settings:
25 inches above ground at 4 inch coulter depth
7.5 inches coulter shank distance (height)
1 inch release height .
Coulter Height Adjustment
Coulter height is the main control for application height.
Coulters may need to be lowered for rows in tracks.
Coulters applicator-wide need adjustment as blades
wear.
Coulters may also be set for rigid row alignment, or
limited castering.
For fields where frequent sharp turns are unavoidable,
you can reduce coulter plowing by allowing the coulters
to caster at the pivot casting. Loosen the jam nuts .
Loosen the set screws just enough to allow the casting to
swivel. Tighten the jam nuts. Do not remove the center
stop screw.
As blades wear, keep the release height constant by
raising the applicator weldment on the coulter arm.
Loosen the bolts . Slide the weldment up. Tighten the
bolts.
If the application height is still too low after this
adjustment, the coulter blades may be worn and in need
of replacement.
