
Row Unit Opener Disks
Sharp Object Hazard
Coulter and disk blades are sharp. To avoid
serious injury, wear gloves when working in
this area.
Crushing Hazard
Verify machine is secure before working on it.
A falling machine can result in serious injury or
death.
The openers have three adjustments:

Planting depth

Openers disk-to-disk clearance

Side depth wheel/opener disk clearance
Planting Depth
The T-handle sets planting depth by limiting how
high the side depth wheels ride relative to the opener
disks. The position of the seed tube is fixed relative
to the disks and is not adjusted.
To adjust seed depth:

Move the T-handle forward (A) for shallower
planting.

Move the T-handle back (B) or deeper planting.
Disk Contact Adjustment
Opener disk angle and stagger is not adjustable, but
disk-to-disk spacing is, and may need attention as
disks wear. Spacers will need to be reset when disks
are replaced.
The ideal spacing causes the disks to be in contact
for about 2.5 cm (1 in). If you insert two pieces of
paper between the disks, the paper should slide from
touching to 3.8 cm (1-1/2 inch) from each other (A).
If the contact area is significantly larger or there is a
large gap, adjust by moving one or more spacer
washers.
To move spacer washers:
1. Raise the planter and install lift cylinder locks.
2. Remove the side depth wheels on the row unit
needing adjustment.
3. Remove the bolt (1) retaining the opener disk (2)
on one side.
4. Carefully remove the disk. Do not lose the hub
components and spacer washers (3 and 4).
5. To reduce the spacing between disks, move one
spacer washer from the inside (3) to the outside
(4) of the disk.
6. Reassemble and check the disk contact.
Side Depth Wheel Adjustments
For disk-to-wheel angle and clearance, the side
depth wheel (1) should just be touching the opener
disk (2) when the wheel is raised to planting depth.
