Coulter Adjustment
The frame-mounted coulters standard on the
YP2425F-2470, YP4025F-1630 and YP4025F-1670 are
configured for “zone” application: 5cm offset from seed
furrow, and
5cm depth, or “2x2”in.
As blades wear, or under unusual field conditions, you
may need to adjust the coulter depth. If the depth is
adjusted, the applicator needs to be adjusted as well.
Coulter Height Adjustment
Refer to Figure 17
1. Raise the planter. Install transport locks.
2. Move the planter to a flat level surface. A paved area
is ideal.
3. At each coulter, measure the raised tool bar height
(“Bar_Height”) .
4. For a 2.5cm (2in) coulter depth, compute the ideal
raised height of the disk edge.

Inch:
5. Reset the coulter shank to the new “Edge_Height”.
Coulter Applicator Adjustment
Normally, the coulter tine tip is set to exactly ground
