Hello; Abram Dietrich Thiessen of Eyebrow Saskatchewan in the 1940s built the first quick attach front end loader. International Harvester's took a picture of the loader and replicated it at the Regina Agribition in November of the same year. Front-end loaders (FELs) are popular additions to compact utility tractors and farm tractors. Compact utility tractors, also called CUTs, are small tractors, typically with 18 to 50 horsepower (37 kW) and used primarily for grounds maintenance and landscape chores. There are 2 primary designs of compact tractor FELs, the traditional dogleg designed style and the curved arm style. John Deere manufactures a semi-curved loader design that does not feature the one piece curved arm, but also is not of the traditional two piece design. New Holland introduced a compact loader with a one piece curved arm on its compact utility tractors, similar one piece curved arm loaders are now available on compact tractors on many brands including Case IH/Farmall, and some Montana and Kioti tractors. Kubota markets traditional loader designs on most of its compact tractors but now features a semi-curved loader design similar to the John Deere loader design on several of its small tractors.
