The purpose of the Murray Quick Hitch Attachment is to allow the operator to change quickly from one implement to another. This is done by releasing the locking lever at the side of the Quick Hitch, driving out of one implement and into the next and closing the locking lever again. The locking lever can be operated remotely by a hydraulic cylinder if required and is offered as an option.
The Murray Quick Hitch is a "dedicated" hitch. For example - a Quick Hitch for a Ford loader will pick up implements with Ford fittings only, a Quick Hitch for a JCB loader will pick up implements with JCB fittings only and so on.
Quick Hitch attachments can also be manufactured for loading shovels, they work in the same way as the smaller quick hitches, but they are much more heavily constructed.
