the current or new position causes it to contact the
ground during adjustment.
2. Dismount the row cleaner, if installed, to reduce
risk of injury.
3. Determine the current opener and coulter
depths.
4. Determine which new hole will position the
coulter closer to the 1/4 inch (6 mm) depth by
using the table.
5. Remove the 5/8 x 4 inch bolt, lock washer, and
nut (7).
6. Move the coulter blade to the new position.
7. Install the bolt and washer locker with the nut.
8. Readjust row cleaners, if installed.
If a worn coulter cannot be adjusted to the proper
operation depth, replace the coulter blade.
Coulter Row Adjustment
For unit-mounted coulters, the ideal alignment is for
the blade to open a furrow directly ahead of the
opener disks.
To check alignment, sight along the coulter blade
centerline (1), the gap between the opener blades,
and the centerline between the press wheels. If they
are out of alignment, either the coulter or the press
wheels (or both) may need to be adjusted.
Operate the planter on 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 Adjustments ” on page 42.
To adjust coulter alignment:
1. Loosen the four bolts that attach the coulter
bracket to the row unit.
2. The holes on the row unit are slotted (2) for
adjustment.
Keep the coulter blade vertical while adjusting.
If the blade cannot be aligned, check that the
blade spindle is using the same hole location on
each side of the bracket.

Seed Firmers
Sharp Objects Hazard
Disk blades are sharp and may result in
injury. Wear hand protection when working
in the area.
Keeton Seed Firmers
A Keeton seed firmer has a polymer shape that
slides down the seed trench. It traps the seeds as
they exit the seed tube and firms them into the
bottom of the seed trench.
