Abstract

A rotatable drive for a feeder and a header of an agricultural combine for drivingly connecting spaced rotatable elements on the feeder and the header to a rotatable power source on a chassis of the combine, the feeder and the header being jointly mounted to the chassis for pivotal movement relative thereto about a predetermined pivotal axis through a predetermined range of harvesting positions. The drive includes a first gear box mounted on the feeder for pivotal movement therewith and including a rotatable input, a first rotatable output rotatably connected to the input and to at least one of the rotatable elements, and a second rotatable output rotatably connected to the input. The drive includes a second gear box mounted on the feeder and having a rotatable input rotatably connected by a drive shaft to the second output of the first gear box and at least one rotatable output connected to another of the rotatable elements. A plurality of drive shafts are rotatably connected in end to end relation one to the other, respectively, between the rotatable input of the first gear box and the rotatable power source on the chassis of the combine, one of the drive shafts being rotatably connected by universal joints on opposite ends thereof to another of the drive shafts and to the input of the first gear box, respectively, and having an axial center portion intersecting or located substantially coincident with the pivotal axis when the feeder and header are within the range of harvesting positions.
