Abstract: A seed tube guard assembly for agricultural planters has floating wear plates to improve the wear life of the seed tube guard. The assembly includes a support bracket having an upper end attached to a planter shank assembly and a lower end positioned between a pair of opener disks. A seed tube guide extends rearwardly from the support bracket for receiving a lower end of a seed tube. A pair of dowels are pressed into openings in the support bracket and protrude from the sides thereof. A metal ball is press fit into an opening in the support bracket between the dowels with opposite sides of the metal ball protruding from the respective sides of the support bracket. The floating wear plates are supported by the dowels on the respective sides of the support bracket with the metal ball engaging the wear plates at respective fulcrum points between the dowels.

Abstract: A pivot assembly for attaching a closing wheel arm to a bearing housing of a no-till drill has a pair of sleeve bearings, a pair of seals, and a pivot bushing or pivot pin that extends through the sleeve bearings and seals. The sleeve bearings are press fit into opposite ends of a bore of the bearing housing and have grooves formed across bearing surfaces thereof for grease to flow to outer ends of the bearings. The seals are also press fit into the opposite ends of the bearing housing bore. The pivot bushing or pivot pin is installed into the sleeve bearings with an outer surface thereof providing a close-running fit with the bearing surfaces of the sleeve bearings. The close-running fit has a clearance within the range of 0.001 to 0.002 inch and can be provided by passing a reamer through the inner bore of the sleeve bearings.

Abstract: A pivot assembly is provided for attaching a closing wheel frame to a planter. The closing wheel frame has a pair of closing wheels attached at a rear end and a pair of mounting openings formed at a front end. The pivot assembly includes ball bearings having outer races fit loosely within each of the mounting openings of the closing wheel frame. The inner races of the ball bearings are secured to the planter frame using threaded nut and bolt assemblies. The closing wheel frame is pivotal relative to the planter frame during normal operation by relative movement between the inner and outer races of the bearing. Variations of the mounting openings in the closing wheel frame are disclosed, including a tubular part, heavy washer or other annular structure welded to an outside surface of the closing wheel frame, or a bearing housing formed integral with the closing wheel frame.
