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 83 on page 70)
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 54.
Press Wheel Stagger
The factory stagger setting has been found optimal for
residue flow. If your conditions appear to require even
press wheels, you might try one row before
re-configuring the entire planter. To change the stagger:
1.
Raise the planter. Secure with blocks or jack stands.
2.
Remove the bolt
, nut
and lock-washer
for the
left press wheel
.
3.
Move the spacer
and wheel
to the forward of
the two mounting holes at
.
4.
Re-install the bolt, lock washer and nut. Tighten.
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 54.
