ABSTRACT:
A tool assembly for use in manually pulling fence posts vertically from the ground. Basically, the assembly includes a first tool having an elongated handle and a bifurcated end sized to fit around a post to be pulled. A pair of hooks extend from the bifurcated end. A second tool basically includes an elongated handle having a transverse rod at one end and a pad adjacent to the transverse rod and extending slightly further from the handle than the rod. In use, the hook end of the first tool is positioned at a substantially perpendicular angle to the post with the hooks extending around the post and pointing upwardly. The rod on the second tool is brought into engagement with the hooks with the second tool angled downwardly from the end. The interlocking ends are slid down the post as the second tool handle is rocked upwardly to a horizontal position with the pad and the base of the hooks engaging the post. As the ends of the handles are lifted to pull the post, the surfaces engaging the post are levered tightly against the post, preventing slippage along the post.
