Re Mace Canute post: Many moons back when I was a kid, and the earth was still cooling, dad bot a mower which was probably one of the first rotary models. This was in the 40s after the war, probably 46 or 47. Can't remember the name, but it was built and designed very well. Your idea reminded me of the blade system. It had a flat bar with a standard triangular sickle blade attached with one bolt at each end. Worked great, if hit something it just folded the blade back a bit. I would change the blade every time I mowed, or just turn it over if only used once. Always had a sharp blade. We had several blades so I only had to sharpen the blades once in a while and they were easy to change. Hit the 6 inch Crescent wrench once and put a nice bend in it, still have it. Only folded the sickle blade back a little. Apparently the Meg-Mow system uses a floating blade which sounds like a good idea. This mower had a 3/4 hp Briggs, was painted sort of a light beige color, had two thin aluminum disk wheels on the front, aluminum main frame/deck, was self propelled with a machined cone clutch on each wheel that worked great.
Does anyone remember the name?
