25 Series Coulter Row Alignment
Refer to Figure 40
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
Adjustment” on page 47 for press wheel alignment.
Refer to Figure 40
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.
