Press Wheel Adjustment

The press wheels close the furrow which gently presses
the soil over the seed to ensure good seed-to-soil con-
tact for even emergence.

To provide consistent seed firming, the press wheels are
free to move downward from their normal operating posi-
tion. 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:

Refer to Figure 102
1.

Down pressure (shown at maximum)

2.

Wheel stagger (shown staggered)

3.

Centering (see Figure 104 on page 82)

Press Wheel Down Pressure

Handle

sets down pressure, which may need adjust-

ment 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.

Note: Higher press wheel down pressures reduce the

down force on the main row unit shank compo-
nents, such as the openers. High press wheel set-
tings may require an increase in overall row unit
down force. See page 66.

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-configur-
ing the entire planter. To change the stagger:

Refer to Figure 103
1.

Raise the planter and install the lift assist cylinder
locks. See “Lift Cylinder Lock-Up” on page 29.

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 66.
