  • Patent number: 4721335
    Abstract: A post-puller adapted to be utilized by a farmer or similar person who is riding on a tractor or equivalent piece of equipment, the tractor having an attachment with the capacity to produce a vertical lifting load--to pull a fence post out of the ground. The apparatus includes a cage-like frame with an opening that passes centrally through the frame, the apparatus being adapted to pass over the top end of the post to be pulled. The cage-like frame has two spaced gripping members on its interior; these gripping members are preferably made of angle iron that is oriented so that the apex of the 90 degree angle will bear against a post that is positioned inside the cage. A lever is pivotally mounted on the side of the cage opposite the gripping members, and the lever has a surface or edge that bears against one side of a fence post to wedge it against the gripping members on the other side.
