Coulter Row Alignment
Refer to Figure 95
For 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 center-line
, 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 planter 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 86 for press wheel alignment.
Refer to Figure 96
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.
