Abstract
The present invention relates to a post puller for posts of a given cross section that includes concrete bases. The post puller comprises in combination: (i) a fulcrum having a horizontal base, a pair of upright arms extending from the base and a pivot pin of circular cross section attached between the arms remote from the base and perpendicular to the upright arms; (ii) a lever of circular cross section in pivoting contact with the fulcrum as a wooden post is extracted, the lever including a handle of fixed length relative to the fulcrum and a lifting segment, and a perforated plate sized to connect to the wooden post to be extracted for coupling the latter to the handle of the lever. As to item (ii), supra, the perforated plate also connects to a pair of chains of at least three links manipulated such that the center link interlocks with the end links and hence direct lifting force from the lever to the perforated plate and permit lifting of the post away from the earth's surface in concert with the perforated plate.
