Abstract: An articulated harvester includes a powered harvester having a pair of forward wheels or tracks, having a pair of rotatable rearward caster wheels, and carrying an on-board harvester grain bin for housing harvested grain. The harvester tows a grain cart, which carries a grain cart bin for housing harvested grain. A joint assembly interconnects the harvester and the grain cart. The joint assembly includes a grain cart tongue that mates with the harvester. An articulation cylinder assembly connects the harvester and the grain cart tongue in the region of the joint assembly. Bi-directional, biased guide rods connect between the grain cart tongue and the caster wheels. The grain car may be steerable and/or powered. The harvester may be steerable by its pair of forward wheels or tracks. A conventional harvester and grain cart assembly can be converted into the novel articulated harvester.

Abstract: Disclosed is an improved grain unloader for off-loading (unloading) grain from a grain bin carried by one or more of a combine or a grain cart. A second grain movement assembly is coupled in parallel to the first grain movement assembly so that both grain movement assemblies can simultaneously off-load the grain bin. A third grain movement assembly feeds the second grain movement assembly. The first and second grain movement assemblies move together from a stowage position to an unloading position. The third grain assembly can only feed the second grain transfer assembly when the second grain assembly is in the off-load position.
