firming wheels provide 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
firmers.
To lock up Seed-Lock wheels:
1.
Raise drill.
2.
Rotate Seed-Lok

Press Wheel Adjustment
The press wheels close the furrow which gently presses
the soil over the seed to ensure good seed-to-soil
contact for even emergence.
To provide consistent seed firming, the press wheels are
free to move downward from their normal operating
position. This system maintains closing/pressing action
even if the row unit arm is lifted when the disks encounter
obstructions.
There are three adjustments available on the press
wheel assembly:
1.
Down pressure (shown at maximum)
2.
Wheel stagger (shown staggered)
3.
Centering (see Figure 134 on page 86).
Press Wheel Down Pressure
Handle
sets down pressure, which may need
adjustment for different soil types and field conditions.
•
Relax the handle forward (in the direction of travel)
for decreased down pressure.
•
Pull the handle
back for increased down pressure.
Higher press wheel down pressures reduce the down
force on the main row unit shank components, such
as the openers. High press wheel settings may
require an increase in overall row unit down force. See
page 71.
