CONSTITUTION: The body(1) of the blade for a weed cutter is connected to a front end part of the weed cutter and has a recess(2) at the lower central part. A passing through hole is formed at the central part of the recess and a nut to which bolts of the front end of the weed cutter and a cover are fastened is placed therein. The bolts are used to fix rotational cutting strings made of nylon.
