You must have seen a backhoe, but may not know that it is called a backhoe. Whenever a building is being made or roads are dug it is used to lift chunks of earth. It is actually a machine used for excavating. It is a device which is attached to the rear side of the tractor. It lifts heavy stuff like earth or any other heavy load.
It is very expensive and if you have a one time need for it then instead of buying it you can take it on rent. It has got its name because the scooper type bucket that is placed at the rear side of the tractor. It performs the work that a bulldozer does. The device is mounted on a tractor. The biggest advantage is that it can be taken directly to different areas, whereas other machines have to be towed into the work area. Hence these other machines need outside power sources.
It needs a lot of operators skill to operate it. An inexperienced operator will not be able to use it, http://www.backhoesandcats.info lists requirements. The design of the backhoe is like a human hand/arm is extending to scoop something or to keep something. Thus, to operate it you need a lot of skill and expertise.
Nowadays backhoes are run on hydraulic...
