Abstract: A press wheel includes a hub which rotates about an axis. A rim extends generally radially from the axis. The rim has a center plane defined as a plane perpendicular to the axis and generally bisecting the rim and defining the center of the wheel. The press wheel includes a plurality of tread portions extending away from the center plane. The plurality of tread portions have voids between adjacent tread portions on the same side of the rim, which in response to the wheel rotating, operably places consecutive adjacent tread portions proximal to the ground. The rim and tread portions are configured to contact the ground.

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.

Abstract: A trailing arm assembly includes a frame bracket attachable to a planter towing frame, a first frame, and a four bar parallel linkage connecting the frame bracket and the first frame with a first pivot and a second pivot on the frame bracket and a first pivot and a second pivot on the first frame. The trailing arm assembly also includes an adjustable biasing member extending from the parallel linkage to the frame bracket. The parallel linkage is connected between the first frame and the frame bracket such that the parallel linkage maintains a parallel orientation of the first frame. The adjustable biasing member is adjustably connected to a portion of the parallel linkage.

Abstract: A wheel scraper for an agricultural planter includes a body defining a mounting portion, a biasing portion extending from the mounting portion, and a tine portion extending from the biasing portion opposite the mounting portion. The mounting portion is configured to couple the wheel scraper to an agricultural planter relative to a wheel on the agricultural planter such that the tine portion is arranged extending adjacent to an outer circumferential surface of the wheel and separated from the outer circumferential surface by a clearance. The biasing portion is configured to resiliently bias the tine portion relative to the outer circumferential surface.

Abstract: A trailing arm assembly includes a frame bracket, a first frame, a parallel linkage, an adjustable biasing member, and a second frame. The frame bracket can include a first connection portion and a second connection portion. The parallel linkage pivotably connects the frame bracket and the first frame via a first pivot and a second pivot on the second connection portion of the frame bracket and a third pivot and a fourth pivot on the first frame. The adjustable biasing member pivotably connects to the frame bracket at a first end and pivotably connected to the parallel linkage at a second end, wherein the adjustable biasing member is configured to provide a downward force on the first frame. The second frame is connected to the first frame via a second parallel linkage.
