Abstract
Disclosed herein is a separable mower blade comprising a stem portion affixed to the drive axis of a rotary type mower shaft, a blade connected thereto and a slot disposed on the blade for reception of a bolt which is affixed to the stem portion so as to fasten the two together. A shroud is provided over the area of interconnection so as to firmly affix the two elements, the blade and the stem together and is so constructed to allow its easy removal so that blades may be taken off with a minimal amount of time and tools used therefore.
