<p>A drive system for the power-operated components of a pull-type windrower, including a fore- and-aft shaft on the windrower draft frame adapted to be driven by the draft vehicle, a first transverse countershaft on the windrower main frame adjacent to and drivingly connected with the fore- and-aft shaft, and a second transverse countershaft on the main frame above and spanning the swath opening in the central portion of the frame and drivingly connected with the first transverse countershaft. A reciprocating cutter bar on the leading edge of the windrower grain platform and a transverse reel mounted above and forwardly of the cutter bar are driven from the first countershaft, the reel drive including a spring overload release mechanism, and a pair of platform canvases on opposite sides of the swath opening are driven from the second countershaft.</p> |
