ABSTRACT:
A guide link mechanism is supported from the draft tongue of a pull-type harvester and connected to the gearbox mounted on the crop harvesting header to provide rotational power thereto wherein the guide link is supported from a sliding mechanism mounted on the tongue that accommodates the changes in distance in respective points associated with the pivotal movement of the draft tongue about a different pivot center than the gearbox. The sliding mechanism includes a bracket affixed to the underside of the draft tongue and low friction inserts, such as nylon, phenolic, urethane or polyethylene inserts, carried by the bracket. The guide link is connected to a slider plate that is slidably received by the phenolic inserts to permit a sliding movement thereof relative to the draft tongue. The rearward end of the guide link is pivotally connected to the gearbox to accommodate vertical movements of the crop harvesting header relative to the draft tongue. The guide link mechanism effects pivotal movement of the gearbox in response to the pivotal movement of the draft tongue to minimize angular deflection of the universal joints in the drive line supported on the draft tongue to deliver rotational power to the gearbox.
