Backhoe loader, also called a Loader backhoe, is an engineering vehicle, consists of a tractor, front shovel\bucket and small backhoe in the rear. Due to its (relative) small size and versitility, backhoe loaders are very common in urban engineering and small construction projects (such as building a small house, fixing city roads etc).

The Backhoe loader is probably the most common variation of the classic farm tractor. As the name implies, it has a loader assembly on the front and a backhoe on the back. When both the loader and the backhoe are permanently attached it is almost never called a tractor, not generally used for towing and usually does not have a PTO. When the backhoe is permanently attached, the machine usually has a seat that can swivel to the rear to face the hoe controls. Removable backhoe attachments almost always have a separate seat on the attachment itself.
Backhoe-loaders are very common and can be used for a wide variety of tasks: construction, small demolitions, light transportation of building materials, powering building equipment, digging holes, breaking asphalt, and paving roads. The backhoe bucket can often be replaced with other tools such as a breaker for smashing concrete and rock. Some loader buckets have a retractable bottom, enabling it to empty its load more quickly and efficiently. Retractable-bottom loader buckets are also often used for grading and scratching off sand. The front assembly may be a removable attachment or permanently mounted. Often the bucket can be replaced with other devices or tools.
Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs in areas too small for larger equipment. Their versatility and compact size makes them one of the most popular urban construction vehicles.
