History and Patent Info
Reports of the creation of the first post hole digger/auger can be dated back to 250 B.C in Greece to remove water from large ships. However, it wasn’t until the 19th century that the first patents were being created and factories began to produce these manual diggers. The first patent was developed by a man named Mead M. Hubby of Maysfield, Texas on November 2, 1880. This design was made to be used in any soil type by twisting a screw-like blade into to ground to remove dirt and have a uniform hole. The next major patent was filed by Jacob H. Lawry of Lenior City, Tennesee on April 7, 1908. His design incorporated the traditional clam-shell diggers bolted together and attached to wooden handles to create an easier way to penetrate the ground and remove dirt to create a neat and uniform hole.

Modern post hole diggers/augers can be power by gas or electric motors. The post hole diggers/augers are either hand-driven or attached to machines like tractors or skid steers. These attachments reduce the time it takes to dig post holes. Kansas prairie farmers claim that the new digger only takes them a minute to dig two and a half foot hole.

Materials and Uses
There are two types of post hole diggers, a clam-shell post hole digger, and the auger style post hole digger. Both styles use metal for the head of the tool and bolts that hold it together. Often the shovel-like head of the clam-shell diggers is sharpened at the end to penetrate the dirt and cut a hole that is round and even. The Auger style post hole diggers have metal screw-like heads that cut into the dirt and shaft that goes up to a wooden handle for turning manually or a steel plate for attaching to a tractors PTO shaft or with a skid steer being attached with pins and hydraulic lines.
