Interesting.The styling and colors look similar to my Bob-Cat snowthrower!I'm not sure if they made tillers???
I don't think it's a Gilson, as I have one and it looks nothing like the one in the photo. The Gilson had an unusual handle set up. It rotated to the side so you didn't walk in the tilled soil but maintain full two hand control. As it would go faster in reverse than forward, the handle would rotate 180 degrees so you could run it (backwards) to and from the shed.looks like a gilson or a wards which are really the same but color would make you think old cub cadet bob
