OPERATION AND MAINTENANCE
Opener – Press Wheel
Adjustment
1. The seeding depth of each individual opener is
controlled by the press wheel depth adjustment (See
Figure 4-23.) To change the depth of each press
wheel, raise the openers so there is not any weight
on the press wheel. Pull up on the adjusting handle
and slide the depth stop forward or rearward to
obtain the desired seeding depth. Each notch
represents approximately 5/16” in depth. Slide the
handle forward for shallower seed placement, and
rearward for deeper seed placement.
IMPORTANT
Increasing opener down pressure does not increase
seed placement depth.
2. As long as the presswheel is carrying weight, the
seeding depth is regulated by the press wheel
adjustment. An increase in down pressure does not
change the depth of seed placement.
3. Make sure the hitch is level when planting to insure
consistent planting depth. A hitch that is too high or
too low can change how the press wheel contacts the
ground and affect seeding depth.
4. When planting seeds shallow, or in loose/soft
conditions, it may be necessary to install stroke
control stops on the hydraulic cylinders. This will
allow the drill transport tires to carry more weight,
raising the drill, and keeping the openers from
planting too deep.
