Title:	Extruded bat for the reel of a crop harvesting header
Abstract:	A removable bat attachment to be applied when required over the tine tubes and fingers of reel of a harvesting machine is formed by an elongate flexible plastic extruded member having a first wall lying against the leading face of the plurality of fingers, a second wall at the inner edge of the first wall wrapping around the tine tube to define a generally cylindrical channel shaped receptacle to receive the tine tube therein and a third wall at the outer edge. In one arrangement the outer edge wraps around an outer end of the fingers and is snap fit onto the outer ends of the fingers and on to the tine tube so as to be held in place thereon by the snap fit. In another arrangement the outer edge has an end wall with a series of holes one for each finger so that the fingers project outwardly from the outer edge.
