Messertrommel fuer Feldhaecksler

摘要

A forage harvester has a cutting reel of three pairs of radially extending supporting plates with each supporting plate having two concentric rows of equally spaced mounting holes for passing bolts to fasten cutting blade mounting blocks between the plates of a given pair. The blocks project beyond the edges of the blades and have contoured end surfaces to seat spirally shaped cutting blades on the blocks. The blades are bolted to the blocks so that these bolts will shear more readily than the mounting bolts through the plates. The blades are positioned on the mounting blocks by retractable gauge pins exteriorly positioned on the opposite side walls of the forage harvester a radial distance equal to the radial distance from the center of the cutting reel to the shear bar.
