Seed Firmer Adjustments
Sharp Object Hazard
Coulter and disk blades are sharp. To avoid
serious injury, wear gloves when working in
this area.
A row unit includes a seed flap, and accepts an
optional seed firmer.
The seed flap requires no adjustment, but may need
to be replaced if worn, or may need to be shortened if
an optional seed firmer is added.
Seed - Lok™ Firming Wheel
An optional Seed - Lok™ firming wheel provides
additional seed-to-soil contact. The wheels are
spring loaded and do not require adjusting.
In some wet and sticky conditions the wheels may
accumulate soil. To avoid problems associated with
this, you can lock-up the Seed-Lok wheels:
1. Pull the catch wire aside (1).
2. Pull up on the arm (2).
3. Engage the wire.
Opener Depth
Set opener seeding depth (A) by adjusting press
wheel height.
To adjust, first raise the openers slightly, then lift and
slide the T-handles (1). Adjust all press wheels to the
same height.
 Each increment of the handle adjusts the
seeding depth by approximately 3.2 mm. The
range is approximately 0 to 89 mm seeding
depth.
 For more shallow seeding, slide T-handles
forward (2) toward the implement.
 For deeper seeding, slide the T-handles back (3)
away from the implement.
If moving the T-handle back does not cause the
opener to achieve the desired depth, lower the
coulters by lowering the frame height, and increase
weight transfer pressures if necessary.
If coulters are installed, set the coulter depth with the
tool bar height. Adjust the opener depth to be 13 mm
shallower.
If no coulters are installed, adjust the tool bar height
so the opener frame runs level at the desired seeding
depth.
