Abstract
A row crop unit (10) is provided with cooperating pairs of molded belts (40), the belts (40) being supported from overhead frame members (20, 22, 24, 26) whereby the build-up of trash within the unit is minimized. A cutoff mechanism (100) is provided, the mechanism (100) being driven by a drive mechanism (110, 112, 114, 116, 118, 120) independent of the belts (40) whereby high driving torques on the belts (40) are avoided. The forward ends of the belts (40) are carried by spaced apart sprockets (56) located forwardly of the cutoff mechanism (100) to insure that standing crop material is properly gathered and engaged prior to severing by the cutoff mechanism (100).
