  • Patent number: 6959768
    Abstract: A weed puller includes a handle, a pair of tines extending from the bottom of the handle, and a step extending back from the handle. The tines are pushed into the ground near a weed by pressing down (by foot) on the step. The handle is then pulled back. This causes the tines to pivot and lift the weed (and its root structure) out of the ground. The pivot occurs about the outer-most end of the step. The step is wider than the pair of tines so that the downward pressure on the step is distributed about a relatively large surface area. Thus, the entire step remains above ground, without breaking the ground below the step, to minimize the portion of the ground that is broken by removal of the weed.
