ABSTRACT:
A portable hydraulically driven posthole digger is provided. The present invention is mounted to an existing loader-type tractor or skid steer loader by the use of a ball and socket type attachment such as a trailer ball and trailer tongue apparatus. The tongue is mounted vertically above the post hole digger and the trailer ball is mounted on the loader such as the bucket on a front end loader. The posthole digger's hydraulic motor is powered off of the existing hydraulic system of the equipment being used. This configuration not only provides an inexpensive method of digging post holes, but further requires a minimal amount of mounting hardware and can be easily removed and stored when not in use.
