With the advent of hydraulic powered attachments such as a tiltrotator breaker a grapple or an auger the backhoe is frequently used in many applications other than excavation and with the tiltrotator attachment serves as an effective tool carrier. Many backhoes feature quick coupler (quick-attach) mounting systems for simplified attachment mounting dramatically increasing the machines utilization on the job site. Backhoes are usually employed together with loaders and bulldozers. Excavators that use a backhoe are sometimes called "trackhoes" by people who do not realize the name is due to the action of the bucket not its location on a backhoe loader.
In the same year 1948 JCB launched the first European hydraulic loader and followed that in 1953 with a backhoe with a 180° slew fitted to a tractor. Then in 1957 while Case produced the first "integrated" Tractor Loader Backhoe in the US (whereby all the components were manufactured and warranted by the same manufacturer) JCB introduced the first dedicated backhoe loader (whereby the loader and backhoe were permanently attached to the chassis allowing them to be more robust rather than being demountable accessories for an agricultural tractor).4 In 1965 they would follow this with the worlds first 360° excavator.
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/excavation landscaping breaking asphalt and paving roads. Often the backhoe bucket can also be replaced with powered attachments such as a breaker grapple auger or a stump grinder. Enhanced articulation of attachments can be achieved with intermediate attachments such as the tiltrotator. Many backhoes feature quick coupler (quick-attach) mounting systems and auxiliary hydraulic circuits for simplified attachment mounting increasing the machines utilization on the job site. Some loader buckets have a retractable bottom or "clamshell" enabling it to empty its load more quickly and efficiently. Retractable-bottom loader buckets are also often used for grading and scraping. The front assembly may be a removable attachment or permanently mounted.
