==History== [[File:60 Jahre Unimog - Wörth 2011 040 (5797928784).jpg|thumb|left|Modern [[Unimog]] as a backhoe loader]] Evolving in parallel to development in the U.S., backhoes were first produced in the UK in 1953 by [[JCB (heavy equipment manufacturer)|JCB]], but it was just a prototype. The world's first backhoe loader with factory warranty was introduced in the U.S. by J.I. Case in 1957. Their Model 320 was the world's first serial backhoe loader. Although based on a tractor, a backhoe loader was and is almost never called a ''tractor'' when both the [[Loader (equipment)|loader]] and the [[backhoe]] are permanently attached. Backhoe loaders are also not generally used for towing and usually do not have a [[power take-off]] (PTO) as often this is used to drive the hydraulic pump operating the attachments. When the backhoe is permanently attached, the machine usually has a seat that can swivel to the rear to face the [[Hoe (tool)|hoe]] controls. Removable [[backhoe]] attachments almost always have a separate seat on the attachment itself. [[File:Koparko ladowarka.JPG|thumb|A typical European backhoe-loader; these usually have a side-shift backhoe mount and vertical stabilizers.]] In Britain and [[Ireland]] they are commonly referred to simply as JCBs; they are popularly called "JCB" in [[India]]. In the United States, they are often referred to as "backhoes", although the term '[[backhoe]]' only refers to one component. In 1970, Hy-Dynamic, now a division of [[Bucyrus-Erie]], manufacturer of the Dynahoe, was the first company to incorporate a [[four-wheel drive]] system into their backhoe loaders, allowing these models to go over almost any terrain with little difficulty. Since the backhoe was invented, several companies such as Caterpillar and John Deere have changed the backhoe's back arm to be slightly curved like that of an [[excavator]], which can allow more maneuverability.
