Abstract: A furrow closing assembly includes a mounting bracket attachable to a planter opener frame, a rigid closer frame, and a four bar parallel linkage connecting the mounting bracket and the closer frame with a first pivot bearing and a third pivot bearing on the mounting bracket and a second pivot bearing and a fourth pivot on the closer frame. A screw-driven linear actuator extends between the parallel linkage to the closer frame. A shaft of the linear actuator is pivotably attached to a torsion axle that is further fixed to an upper portion of the parallel linkage. A load cell is positioned between the linear actuator and the closer frame.
