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 63.
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 reconfiguring
the entire planter. To change the stagger:
1.
Raise the planter and install the lift assist cylinder
locks. See “
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.
Press Wheel Centering
If one press wheel is running in the seed trench, or the
wheels are not centered over the trench, the angle
of
the press wheel assembly can be adjusted as follows:
1.
Determine how far, and in which direction, the press
wheel assembly needs to move to center the wheels.
2.
Raise planter and install lift assist cylinder locks. See
“
3.
Pick some reference points on the unit to be adjusted
and an adjacent row unit. Measure the distance
between them.
4.
Loosen the rear
1
/
2
inch hex-head bolts
.
Do not loosen the two bolts forward of the hex-head
bolts. One of the forward bolts is square-head. The
other may be hex or square.
5.
Turn the hex head cam
under the forward hex
head bolt
, and obtain the new distance between
the reference points.
6.
Tighten both hex head bolts
.
