1. A backhoe loader, also called a loader backhoe, loader excavator, digger in layman's terms, or colloquially shortened to backhoe within the industry, is a heavy equipment vehicle that consists of a tractor-like unit fitted with a loader-style shovel/bucket on the front and a backhoe on the back.
2. Backhoe loaders are very common and can be used for a wide variety of tasks.
3. Their relatively small frame and precise control make backhoe-loaders very useful and common
