Mini Lawn Dozer
This mini tractor resembles a kid’s toy but is a functional tractor. It is a 1960 M400. Melroe Manufacturing Company built it. The idea originated with the three-wheel self-boosted “Keller Loader.” Eddie Velo, a Minnesota Turkey Farmer, wanted a compact and light loader that could quickly move through his barn’s second floor to tidy up turkey manure. The Keller brothers made him one. Melroe bought the concept from the Kellers and used it to construct the first four-wheel-drive skid steer loader that everyone can see in the picture.
