Tractor in confined areas. The most common variation of the classic farm tractor is the hoe, also called a hoe-loader. As the name implies, it has a loader assembly on the front and a backhoe on the back. Backhoes attach to a three-point hitch on farm or industrial tractors. Industrial tractors are often heavier in construction, particularly with regards to the use of steel grill for protection from rocks and the use of construction tires. When the backhoe is permanently attached, the machine usually has a seat that can swivel to the rear to face the hoe controls. Removable backhoe attachments
Backhoe filed a patent #3,249,244 for the first extendible boom. Patent #3,273,729 was filed in January 1965 by Vaino J. Holopainen for the first hydraulic thumb. Although Wain-Roy Corporation no longer exists, the Wain Roy product line of backhoe attachments and couplers is still available through the Woods Equipment Company of Rockford, Illinois, US. Because of the long-time predominance of the JCB marque in the United Kingdom and Ireland, it has become a genericized trademark there, and backhoe-equipped diggers are commonly called JCBs, while the term "backhoe" as an excavator component is almost unknown to the general public in this context.
