An excavator quick hitch, also known as a quick coupler or quick attach, is a device that allows an excavator to quickly and easily change between different attachments without the need for manual labor. The quick hitch is typically mounted to the end of the excavator arm and is used to connect the excavator to various attachments, such as buckets, hammers, and augers. The quick hitch can be operated hydraulically or mechanically and is designed to securely lock the attachment in place while the excavator is in use. The use of a quick hitch can significantly increase productivity and reduce downtime on construction sites and other earthmoving projects.
