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.
There are three adjustments available on the press
wheel assembly:
