ABSTRACT:
A support blade with a replaceable cutter for rotary lawn mowers. The support blade has a recess at a top portion adjacent each end which receives a replaceable cutter element. The cutter has a body portion which fits snugly in the recess and a laterally extending cutter element which has a front knife edge for cutting and a rear portion which abutts against the blade support in such a fashion that thrust of the cutter is distributed against the blade support and the back of the recess. Protection against damage by foreign objects is provided by connecting the cutter to the top of the blade support by Allen screws fitting into tapped holes in the blade support.
