ABSTRACT:
A ground opener that is allowed to caster in one direction is associated with a pair of arms connected by a pivot connection that allows one arm to move relative to the other arm. The movable arm is forced against the stationary arm when the ground opener impacts the soil as the ground opener is pulled along a relatively straight travel path. When the ground opener is turned radially from the straight travel path, the movable arm may cast away from the stationary arm. The disc opener is coupled to the movable arm through a central hub and, as such, the trailing edge of the disc opener will move away from the stationary arm as the disc opener is turned. When the disc opener has completed the turn, the torque on the disc opener will lessen thereby allowing the movable arm to move back toward the stationary arm.
