Abstract
The single-toothed blade is pivoted at its rear end and driven at its middle section in arcuate reciprocation over the teeth of a fixed base plate by an electric motor. The blade and the slide of the crank-slide blade drive mechanism comprise the wear parts of the sickle-shear and as a subassembly is readily detachable from the crankpin for rapid replacement without the use of tools.
