Headland turns
The preferred procedure when making field end turns is to raise the drill frame. By this method,
the row units maintain down pressure. If the row units are raised on the turns, it is likely that you
will be well into the next pass before down pressure is fully restored.
Down Pressure
The down pressure on the row units is controlled by a hydraulic cylinder on each tool bar. The
cylinders provide a constant down pressure on the tool bars through their entire range of motion.
An active hydraulic circuit maintains uniform pressure to each cylinder and is controlled on the
go by the operator. The down pressure can be adjusted from 150 PSI to a pressure high enough
to raise the drill in frame tires off of the ground (normally from 650-750 PSI. If less pressure is
desired, put hydraulics in float.

Setting the down pressure
The down pressure on the drill has to be set high enough for disc penetration and proper packing.
In hard conditions this may require an optional ballast kit to add weight to the wings frames.
