ABSTRACT:
A mechanical fence post driver for attachment to a lift arm of a standard front-loader which includes a mounting plate, guide tube, and roller latch assembly. The guide tube receives a tee or other fence post inserted therein such that it contacts the mounting plate. The fence post is held in place by a roller latch assembly which compresses the post against the rearward side of the guide tube. Insertion of the fence post into the ground is accomplished by lowering the lift arm while the post is held within the guide cylinder. A rotation plate assembly may be positioned between the mounting plate and guide cylinder to provide a convenient mechanism to rotate the guide cylinder in relation to the mounting plate.
