About Backhoes
Backhoes are heavy machinery designed to be have the ability to move earth. Backhoes can dig in the ground and many come with a front-loader which can be used in the same manner as a bulldozer. Backhoes serve a variety of purposes and are common at construction sites where they are used to dig ditches, foundations and trenches. Many companies manufacture backhoes, including John Deere and Caterpillar. Does this Spark an idea?

Features
-
Backhoes are sometimes called "rear actors" and "back actors" because the actual digging part is the rear of the vehicle. A backhoe consists of a tractor with an attached maneuverable arm that is powered by hydraulics that has a large toothed bucket on the end that digs into and scoops out dirt. The arm is in two sections with the one attached by a pivot joint to the tractor called the boom while the one joined to that that holds the actual bucket is known as the dipper. The pivot joint, or "kingpost," allows the arm on a backhoe to move to the right or to the left.
Function
-
The seat in a backhoe's tractor cab swivels so that the operator can turn around and actually direct the movements of the arm and bucket. A pair of metal "feet" can be used to stabilize the entire rig while the bucket is scooping up and moving dirt. These feet are located at the back of the machine just under where the arm is attached. They provide leverage so that the backhoe does not tip over when it is picking up dirt or other heavy objects.

Types

Backhoes can accomplish many different jobs, with even more being able to be handled if it comes with a front loader. For example, it can plow snow in a large parking lot with the front loader and then with either the front-loader of the backhoe bucket dump it into a waiting truck for removal. A backhoe is most often used to dig long trenches and ditches in which water pipes, telephone cables or a building's foundation will be laid. Certain landscaping jobs can be done by a backhoe alone. Backhoes can smooth terrain that is uneven, take out tree roots with ease, and even tamp down the ground after it has filled in a trench or hole.
Considerations
-
A backhoe does need its operator to be knowledgeable and skillful when it comes to running the machine. There are different joysticks in the cab that allow the hydraulic arm to move back and forth and extend and contract. In this way the backhoe can dig into the ground and then move the dirt to the side out of the way. One of the benefits of using a backhoe is that it can be driven on the road to the site, alleviating the need to have to have a long trailer to move it around.
Expert Insight
-
Today's backhoes have many features that enable the operator to perform a variety of jobs. The Caterpillar 450E backhoe loader, for example, has different attachments. One is an auger bit that is designed for drilling holes that can be used for signs, fence posts, planting shrubs and trees, and other applications. Another is an angle broom that can be used for such purposes as cleaning lumberyards or construction sites. With attachments like these, a backhoe becomes even more valuable and versatile.
