Abstract
A rotor for axial flow combines having an auger of predetermined length on one end thereof which, when rotated, feeds crop material to the main portion of the rotor which coacts with a concave and grate to thresh and separate grain from the crop material. The auger has a spiral flight provided with a smoothly curved peripheral edge and in order to minimize wear of said edge and also provide increased aggressive engagement of the auger with crop material, a series of similar projections are detachably connected to said flight adjacent the peripheral edge thereof, in circumferentially spaced relationship to each other. The projections have a curved apex from which opposite sides of the projection slope in different degrees respectively to provide different operational characteristics, depending upon which edge is disposed in leading position relative to the direction of rotation of the rotor and said projections being detachably connected to the flight of the auger for reversibility thereof as well as replacement purposes.
