ABSTRACT:
A post puller and a method of use are described herein. The method of the invention entails lowering a collar over a top end of the post. The collar is carried by a suitable frame. The frame is attached to a bucket which forms a portion of a front end loader attached to a tractor. The bucket of the front end loader is tilted to engage an upper end and a lower end of the collar with the post. The bucket is then raised to pull the post from the earth. The puller is formed from a frame and a collar. The frame has an open upper end, an open lower end, a front side, and a back side. The frame has a longitudinal axis extending from the open upper end to the open lower end. The collar is mounted inside of the frame. The collar has an open upper end positioned near the open upper end of the frame, an open lower end positioned near the open lower end of the frame, a front side positioned near the front side of the frame, and a back side positioned near the back side of the frame. The collar defines a passage having a longitudinal axis extending from the open upper end to the open lower end to accept the post. During use, the collar slides and rotates with respect to the frame.
