Model History and Information: This set pairs two Cat compact loaders. The Cat 272D is a skid steer loader with a long wheelbase and vertical lift design that gives extended reach and lift height for loading trucks; Caterpillar lists a turbocharged Cat C3.8 engine with 95 hp and a rated operating capacity of 3,200 lb (1,451 kg). Caterpillar classifies the 297D2 as a Multi Terrain Loader, riding on a suspended track undercarriage that provides traction and flotation with very low ground pressure. Skid steer loaders trace back to a compact three-wheeled loader built in Minnesota in 1957 and now accept a wide variety of buckets and other attachments, which is reflected in the interchangeable work tools supplied with this replica pair.
