Abstract
An extraction device eases the task of removing a post, bush or the like from a ground surface. The device includes a pair of legs pivotally coupled together at respective first ends of the legs. A bar is pivotally coupled to a first one of the pair of legs. The bar has a notch extending upwardly into a bottom edge of the bar. A projection is coupled to a second one of the legs. The projection is insertable into the notch to secure the legs in a static position relative to each other. A connector is coupled to an associated one of the legs proximate the first end of the pair of legs. A ratcheting mechanism is removably coupled to the connector. A cable is removably coupled to the ratcheting mechanism for extending around a structural object for removing the structural object from the ground surface.
