Grass cutting machines

This is the patent for the "Flymo", a wheel-less lawnmower that was all the rage for a couple of years in the mid-1960s. In the USA the Flymo design was licensed to Toro. The Flymo mowers proved to be a bit difficult to control, especially on slopes, and left an irregular cut because the blade pushes down the air which tends to flatten the grass as well. |
