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 pressing action even if the
row unit arm is lifted when the disks encounter obstruc-
tions.
There are three adjustments available on the press
wheel assembly and a fourth option on press wheel
assemblies with cast wheels:
Refer to Figure 55
1.
Down pressure
2. Wheel stagger (shown staggered)
3. Centering (see Figure 57 on page 41)
4. Cast Wheel Plow Angle (see Figure 58 on page 41)
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 pres-
sure.
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 29.
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 drill. To change the stagger:
Refer to Figure 56
1.
Raise the drill.
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.
