Abstract
A down pressure adjustment assembly for a disc opener of an agricultural implement includes a rockshaft to which one or more disc opener units are mounted and an actuator that rotates the rockshaft. Rotation of the rockshaft causes the disc opener units to be raised or lowered. When the disc opener units are lowered into a field engagement position, further rotation of the rockshaft will cause compression of down pressure springs for each of the disc opener units.
