25 Series Coulter Row Alignment
Refer to Figure 43
For 25 Series unit-mounted coulters, the ideal alignment
is for the blade to open a furrow directly ahead of the
opener discs.
As a check on coarse alignment, sight along the coulter
blade centerline
, the gap between the opener blades
, and the centerline between the press wheels . If
they are clearly out of alignment, either the coulter or the
press wheels (or both) may be in need of adjustment.
The exacting test of correct alignment is field results.
Operate the drill on some test ground (no seed required),
and verify that the opener blades are in the groove
opened by the coulter, and that the press wheels are
centered over the furrow. See “Press Wheel Adjust-
ment” on page 40 for press wheel alignment.

Refer to Figure 43
To adjust coulter alignment, loosen the four bolts
that
attach its bracket to the row unit. The holes on the row
unit are slotted, side-to-side, and allow the coulter
bracket sideways and rotational adjustment.
Keep the coulter blade vertical while adjusting.
If the blade cannot be brought into alignment, check that
the blade spindle itself is using the same hole location on
each side of the bracket.
