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 pressing action even if
the row unit arm is lifted when the disks encounter
obstructions.
Refer to Figure 97, 98 and 99
There are three adjustments available on the press
wheel assembly and a fourth option on press wheel
assemblies with cast wheels:
1.
Down pressure (shown at maximum)
2.
Wheel stagger (shown staggered)
3.
Centering (see Figure 99 on page 78)
4.
Cast Wheel Plow Angle (see Figure 100 on page 79)
