1957 Skid-steer loader

A skid loader or skid steer loader is a small rigid frame, engine-powered machine with lift arms used to attach a wide variety of labor-saving tools or attachments.Though sometimes they are equipped with tracks, skid-steer loaders are typically four-wheel drive vehicles that can push material from one location to another, carry material in its bucket, or load material into a truck or trailer.Brothers Louis and Cyrill Keller co-invented the first skid-steer loader, which was based around a three-wheeled loader they developed in 1957 for a turkey farmer near Rothsay, Minnesota.
