ABSTRACT:
A combine loading auger comprising a tube having auger flighting located therein. The tube is hinged to a transition housing containing the loading auger sump and held in place by two over-center latches. A first portion of each latch is coupled to the tube and the second portion of each latch is coupled to the loading auger. The transition housing is provided with a gear box drive for driving the auger flighting in the tube. The drive and flighting are provided with a coupling for transmitting rotational motion from the drive to the flighting. The coupling automatically disengages when the tube is lowered into its transport position, and automatically engages when the tube is raised into its working position. The coupling comprises a pair of axially extending engagement lugs mounted on the auger flighting and a pair of radially extending lugs mounted on the gearbox drive. A gas spring extends between the a bracket on the transition housing to the loading auger for counterbalancing the loading auger to facilitate its movement from work to transport positions and vice versa.
