A crop harvesting header includes a reel mounted on a pair of forwardly extending arms carried on a header frame above a table and cutting knife. The reel is rotatable about a longitudinal axis and includes bats with finge rs which pivot each about a respective bat axis so the angle of the fingers varies as the reel rotates. The bat includes a longitudinal tube which supports the fingers at spaced positions along its length. At each finger location the tube is punched to define two diametrically opposed indentations each forming a hole through the tube wall . Each finger has a finger portion of I shape in cross-section and a mounting colla r. The collar only partly surrounds the tube so as to have a portion which can flex open to allow the collar to be wrapped around the tube. Two projections are provided on the inside surface of the collar to project into a respective one of the indentations. A bolt passes through holes in the projections aligned with the holes in the indentations to clamp the projections into the indentations.
