The brothers who invented the first compact loader, later named the Bobcat skid steer loader, have been posthumously recognized as 2023 inductees of the National Inventors Hall of Fame.
In 1957, the Kellers built a three-wheeled loader with two drive wheels in front and a caster wheel in the rear – the precursor to the modern skid-steer loader.
