Abstract

See full text

A soil manipulation device is provided for closing a groove in soil formed by a soil tiller shank. The device includes a frame connected to a rear portion of the tiller shank and a pair of rotatable coulter blades mounted on the frame for engaging soil behind the tiller shank. The coulter blades are positioned on opposite sides of the groove so as to close the groove in the soil behind the tiller shank. The coulter blades are selectively movable and positionable in directions toward and away from each other so as to vary the distance between the coulter blades. The coulter blades also are selectively movable and positionable in a substantially vertical direction with respect to the frame, so as to permit variation in depth of coulter blade penetration into the soil. The coulter blades have side surfaces which are selectively movable and positionable from orientations which are substantially in parallel with the groove to orientations which are out of parallel with the groove, so as to variably manipulate soil on opposite sides of the groove.
