ABSTRACT:
A floor cutter for a plough has a component provided with cutting edges fixed by welding to a main body locating in a holder. The components are connected together with step-like surfaces chamfered at the external faces of the components to faciliate the welding. Superimposed support surfaces extend more or less normally to other surfaces and permit adjustment of the position of the components during welding to vary the set cutting depth.
