A backhoe is a digging equipment with a shovel at the end of an articulated arm mounted on a tractor. Backhoe parts include the boom, ladle, and bucket, with various attachments available. The joint connecting the arm to the tractor allows movement in two planes.
A backhoe is a type of digging equipment consisting of a digging shovel at the end of a articulated arm. It is mounted on the rear of a heavy-duty tractor, which often has a front-mounted loading bucket or shovel. Vehicles of this type are often called backhoe loaders. Backhoe parts are the various components that make up the backhoe itself. A number of specialized backhoe attachments can be installed in place of the digging shovel, also called a bucket.
The knuckle arm that forms the main portion of a backhoe loader is in two parts. The largest section, which connects to the rear of the tractor via a swivel joint known as a kingpost, is called the boom. The joint that connects the arm to the tractor allows it to move in two planes. It can move up and down, extending and retracting its arm and twisting from side to side.
Other major parts of the backhoe are mounted at the end of the boom away from the tractor. This second section of the backhoe boom is connected to the boom by a joint that looks like a human elbow but only moves in one plane. This second section is called a ladle or sometimes a balance wheel.
A bucket, sometimes known as an excavator or shovel, is the third of the three main types of backhoe parts. The bucket on a backhoe is mounted so it digs by pulling back towards the tractor. It is attached to the dipper by a simple single plane joint which allows the bucket to curl up and under the dipper stick as it digs. Sometimes a bucket may come with an attached metal bar, called a thumb. This bar works much like a human thumb when using the bucket to pick up items.
A wide variety of backhoe attachments used in place of the bucket make up another category of backhoe parts. Grappling hooks, which are a claw-like group for grabbing objects, are one of the most common. Some other common backhoe attachments include tree stumps, paving and concrete pulverizers, jackhammers, and root grapples, which are a type of rake-like grapple used to grab masses of tree roots and pull them from Earth.
