发明名称 Puller for fence posts or the like
摘要 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. Lifting upward on the outer end of the lever rotates it to a post-engaging position, and releasing the outer end will allow gravity to restore it to a non-binding position-when there is no weight on the lever as a result of supporting a post. When a rope or the like is used by a farmer to selectively lift the outer end of the lever, the farmer can drive his tractor to a location adjacent a standing fence post, position the cage over the top of the fence post, pull the post of the ground, release the post, and move to another location-all without having to leave the seat of his tractor.
