The present invention concerns a post puller apparatus featuring a plurality of clutching fixtures for extracting posts embedded in the ground, particularly round metal posts that are often difficult to hold firmly. Each such clutching fixture is formed to have a rectangular horizontal plate and a rectangular vertical plate perpendicular to each other along an edge of each. The horizontal plate has a clutch jaw of a generally V shape for receiving a portion of the post to be removed from the ground; the vertical plate has a pair of slots flanking the clutch jaw. Two or more of these clutching fixtures are longitudinally attached to a longitudinal support member, which is normally operative in a vertical position and operatively conjoined with a device providing an upward post extracting force. The longitudinal support member has a maneuvering handle for positioning the post puller apparatus proximate to a post to be removed. Following this maneuver, loose chain for each clutching fixture is wrapped around a portion of the post to be removed, the encircling chain interposed between the clutch jaw and a portion of the post, each loose end of the chain secured in one of each of the slots flanking the clutching jaw. Upon application of an upward extracting force, the chain encircling the post tightens, securely and firmly holding the post in the post pulling apparatus during the extraction process.
