
Unit Mount Coulters (Option)
Sharp Object Hazard
Row cleaner tines, casting edges, and coulter
disks are sharp. To avoid serious injury, wear
gloves when working in this area.
Crushing Hazard
Ensure machine is secure before working on
the machine. A falling machine can cause
severe injury or death.
The best operating depth for coulters is 1/4 inch
(6mm) above the opener depth. The coulters may
have originally been set to this depth, but coulter and
opener disks wear with time, and may need
adjusting.
Adjust the coulter depth by mounting the coulter disk
in one of the six mounting holes on the coulter
bracket.
To adjust coulter depth:
1. Raise and secure the planter. Row units may be
fully lowered or locked up. Do not attempt to
move the blade when the current or new position
causes it to contact the ground during
adjustment.
2. Remove row cleaners, 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 (6mm) depth by the
using the table below.
5. Remove the 5/8 x 4 inch bolt, lock washer, and
nut (7).
6. Move the coulter disk to the new position.
7. Install the bolt and fasten the lock washer and
nut.
8. Readjust row cleaners, if installed.
If a worn coulter cannot be adjusted to the proper
operation depth, replace the coulter disk.
Coulter Row Alignment
For unit - mounted coulters, the ideal alignment is for
the disk to open a furrow directly ahead of the
opener disks.
To check alignment:
1. Sight along the coulter disk centerline (1), the
gap between the opener disks, and the
centerline between the press wheels.
If they are out of alignment, either the coulter, press
wheels, or both may need to be adjusted.
Operate the planter on test ground, no seed
required, and verify that the opener disks are in the
groove opened by the coulter, and that the press
wheels are centered over the furrow. See “
Press
Wheel Adjustments ” on page 50.
