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.

  • Patent number: 5749310
    Abstract: A repair kit is provided for quickly and efficiently repairing a hex drive shaft on an agricultural planter. The invention provides a repair sleeve which is closely coupled with the broken or cut hex drive shaft. This repair sleeve is then attached to either side of a broken drive shaft thus allowing the planter to become operable once again. Utilizing the present invention to accomplish the repair, the planter is quickly and efficiently fixed using a small number of tools and not requiring transportation to a repair facility.
