Gannon manufactured Earthcavators for several brands of tractors including Cub Cadet, John Deere, Simplicity, Bolens, and Sears as well as a 3 pt. version. All the Earthcavators were the same except the front mounting. When we purchased our Earthcavator it was originally manufactured to fit a Simplicity. We modified the mount to fit a Cub Cadet.
