Operation
4. Move the down-pressure cam (2) to the new
setting.
Minimum setting (3) and maximum setting (4) are
indicated by the position of the cam. Each notch
on the cam will increase the down pressure on
the row unit springs. Use the table below as a
setting reference.
Individual rows may be set higher if running in tire
tracks.
Opener Disks
Sharp Object Hazard
Coulter and disk blades are sharp. To avoid
serious injury, wear gloves when working in this
area.
Crushing Hazard
Make sure machine is secure before working
on it. A falling machine can result in severe
injury or death.
The openers have three adjustments:
1. Planting/seed depth
2. Openers disk to disk clearance
3. Depth wheel/opener disk clearance
Setting 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
blades are replaced.
The ideal spacing causes the blades to be in contact
for about 1 in. (2.5 cm). If you insert two pieces of
paper between the blades, the paper should slide
from touching to 1-1/2 in. (3.8 cm) 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).
