摘要：
A crop harvesting header has a cutter bed to cut crop material as the harvester advances through a field. The cutter bed includes a plurality of rotatable cutters having knives extending from opposing ends of the cutters. Each cutter has a generally elliptical knife carrier, and a pair of knives at opposites ends of the carrier, wherein a portion of each knife extends beyond the end of the carrier to expose a cutting surface to sever the standing crop. Each knife is shaped such that its width dimension at a proximal end where mounted on the knife carrier is narrower than its width dimension at a distal end extending away from the knife carrier.
