| 67 | Weed removal tool | US12115120 | 2008-05-05 | US07845696B2 | 2010-12-07 | Stephen D. Hatcher; Peter A. Arcati |
| A manually operable weed remover consists of a cluster of pivotable and rotatable spikes attached to a handle. When positioned over the center of a weed and downward pressure is applied, either by pushing on a bar handle or stepping on a foot rest, a bottom flange is forced up by the ground surface as the spikes are forced into the ground around the weed. The spikes are directed through apertures in the moveable flange and movement of the flange causes the spikes to close around the root of the weed. The insertion motion of the spikes further causes the spike mounting device to rotate relative to the handle and the weed. Thus, as the spikes are being inserted into the ground, the spikes rotate thereby separating the weed root from the adjacent ground. The weed may then be pulled from the ground by upward pressure on the tool. | ||||||
| 68 | Multipurpose gardening and weeding tool that enables the user to easily and effectively remove dandelions and other unwanted weeds in and around yards, around shrubbery, and in and around vegetable and flower gardens | US11818980 | 2007-07-27 | US20090283281A1 | 2009-11-19 | James Herbert Lewis |
| My invention is a multipurpose gardening and weeding tool that reduces the effort of effectively getting rid of weeds, dandelions, and other unwanted vegetation while the user is in an upright standing position. The user places the split tipped end of the tool close to the base of the plant or weed and inserts the tool vertically at the base of the weed. Additional insertion force can be applied by stepping on the heart shaped blade. As the blade becomes the fulcrum, the leverage force removes the weed and its root(s). This very sturdy, uncomplicated tool will enable people working in yards or gardens or around shrubbery to effectively get rid of the unwanted vegetation, roots and all, while the user remains in a standing position. This tool can also be used to prepare the soil to cultivate vegetable gardens and flower gardens and as a hoe to work around individual plants or rows of plants. | ||||||

| 73 | Weed plucker | US10921239 | 2004-08-18 | US06959768B1 | 2005-11-01 | Luis E. Casillas |
| 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. | ||||||
