ABSTRACT:
The disclosed invention is an improved closing wheel attachment mechanism which has longer wear life than that of the typical attachment mechanism. The closing wheel arm on an agricultural planter has installed thereon an improved grease bushing assembly which has increased wear surface and the capability to utilize a grease on the surface. The combination of increased wear surface and greasing will greatly increase the operational life of the planter. Also included in the invention is the process and fixturing to incorporate the improved configuration on to an existing planter closing wheel structure. Included in this attachment mechanism is a welding jig which assures proper alignment of the improved bushing assembly.
