The logo on your lawn tractor is for General Appliance Manufacturing. Probably from about 1970. The pickup box rear fenders were one of their features. They made lawn tractors with names such as Bonanza, Lawn Lion , Maverick, Mustang, Grass Hound, Country Squire, etc. They also made the Bonanza Mini Dune Buggy mowers and Trail Horse mini bikes. They were taken over by Arctic Enterprises in the early 70s.
Seems interesting. Anyone confirm that?
