If you have hugger on old feeder ('81 and prior) It seems P_N would be 71506509. Otherwise the P_N should be 71363098 threw parts or 71371088 threw machinery. This sloped floor begins just behind auger and protrudes into feeder a couple inches. Price is cheap threw AGCO but can be fabricated easily also. Hopefully if hugger is on small machine the feeder has been narrowed up neatly. Also on basically all the Huggers we put out we had to extend flighting on auger to a center intersecting line. Otherwise the corn would build up between gathering chains and auger just ahead of where left and right flighting come together.
