Abstract
Gathering chains for row crop harvester heads which improve yield by minimizing the loss of kernels that may prematurely break loose and be lost to the ground. The gathering chains include continuous loops with a plurality bristle blocks removable attached to the continuous loops. Each of the plurality of bristle blocks include bristles extending laterally therefrom, whereby the bristles form a substantially continuous lateral conveying surface effectively closing an area above and across the width of the slot defined by the stripper plates. The bristles may include fine bristle filaments and coarser bristle filaments that are shorter than the fine bristle filaments.
