Post driver and puller combo

Abstract

A post driver and puller combo includes a hollow main cylinder capable of accommodating a fence post, and a post-pulling mechanism provided at an upper portion of the main cylinder and disposed transversely therethrough. The post-pulling mechanism is freely detachable from the main cylinder. A user can insert a fence post into the hollow main cylinder and hit the top of the fence post to drive it into the ground. To extract the post, the user places the main cylinder at one side of the post and uses the post-pulling mechanism to engage with the post so that it can be pulled out of the ground. The device is a combination of a fence post erection machine and a fence post extraction machine. The device is simple in structure, easy to assemble, light in weight, and easy to transport.

What is claimed is:
