Sawzall does fine. My wife wanted to sift all the dirt in her garden area (a considerable area, down to about 6" deep) and I told her I'd think of something, mostly so that I would not have to be the one who had to stand there and do it. Found a square sifter thingy that would fit in the top of a milk crate, mounted that crate above two sawhorses on swinging arms and rigged the Sawzall (actually a non-Milwaukee brand reciprocating saw) to move it by drilling a hole in the far end of the blade and strapping the saw to the horses. Remote toggle switch on the cord. Worked,
