The Allen Scythe, sometimes called the Allen Power Scythe, is a petrol-powered finger-bar mower. It was made from 1935 until 1973 by John Allen and Sons in Cowley, Oxfordshire. The company was formerly the Eddison and Nodding Company, was bought by John Allen in 1897 who renamed it the Oxford Steam Plough Company, and then renamed it again to John Allen and Sons.
