Abstract
A row crop harvester provided with pairs of coacting power-driven endless belts having a feed path therebetween for stalk-type crop material to be fed by said belts to the harvester from the cutting mechanism thereon, the belts having lug members on the outer surfaces to effect positive engagement with crop material and move it along said feed path, and positive drive for said belts being provided in the form of spaced lugs on the inner surfaces of said belts which are received in complementary openings in rotary support and drive members, the improvement comprising self-clearing members supported adjacent the rotary members and having lugs projectable into the aforementioned openings to clear the same of any extraneous material therein.
