Patent number: 6959768Abstract: 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.Type: GrantFiled: August 18, 2004Date of Patent: November 1, 2005Inventor: Luis E.

The head includes a flared rear portion and a claw with two flanges on the front portion. The bottom face of the head is generally smooth. The top face of the head includes a collar for attachment to the handle. The gripping device rests atop the collar of the head and includes an extension which projects over the surface of the top face forming an aperture.Type: GrantFiled: November 18, 1998Date of Patent: April 10, 2001Inventor: John K. Lampe

Patent number: 6186479Abstract: A framework removal tool method is provided. The tool comprises a first side of a stake contact element including first and second notches with first and second dimensions, respectively. A lever arm connects to the stake contact element. One of the first or second notches is selected based on a dimension of a stake. The selected notch is placed adjacent the stake. The lever arm is rotated to remove the stake. In another embodiment, a second tool for removing stakes is provided. The tool includes a bar with a nail removal notch on a first end, and a stake contact element connected to the bar near the first end. The stake contact element includes at least a first stake notch on a first side. A rounded extension rigidly connects to the bar near the first end.Type: GrantFiled: September 2, 1998Date of Patent: February 13, 2001Inventor: Lowell F. Witter

Patent number: 6138769Abstract: A tool for inserting beneath a plant to sever roots, such as tap roots, that are located beneath a tree or shrub at a location relatively far from the circumference of a root ball, the tool comprising a cutting blade of generally triangular shape having a leading edge which is a relatively narrow cutting edge, and having sides angled inward from the cutting edge. The cutting blade is mounted on a long, slightly arcuate, slender shaft which is sufficiently long to reach under a tree shrub to sever roots and define a root ball in preparation for transplanting the tree or shrub.Type: GrantFiled: May 15, 1998Date of Patent: October 31, 2000Inventor: Stephen R. Breyer

Patent number: 5964451Abstract: A weed removal tool is provided with an ergonomic handle shape which improves user comfort and reduces user fatigue and risk of injury. The handle is provided with a compound gripping surface which has been engineered and shaped to form a flattened egg-elliptical profile when viewed from the side, and a generally widened egg-shaped profile when viewed from the top or bottom. A strong, non-root cutting or severing, engineered shank is provided for gently loosening surrounding soil for removal of weed roots and is provided with a blunted tip for penetrating the soil without severing underlying roots. The shank is carefully engineered, shaped and proportioned to automatically relocate its operating fulcrum point so as to target, create, maximize and concentrate its soil and root loosening and lifting actions directly within the selected plant's root system.Type: GrantFiled: December 28, 1995Date of Patent: October 12, 1999Inventor: Louis C. Sudheimer

Patent number: 5934649Abstract: A hand operated post and pole extraction device for removing a pole or post from the ground. The device includes a frame assembly having a base section, a vertical frame member extending therefrom and a plurality of leverage arms each extending along the length of and substantially perpendicular to the vertical frame member. A handle assembly is pivotally held atop one of the plurality of leverage arms and a chain assembly is removably connected to one end of the handle assembly. When the chain assembly is wrapped around the pole or post and a force is applied to one end of the handle assembly towards the ground, the handle assembly is caused to pivot about the leverage arm applying a force to the opposite end connected to the chain assembly and the pole or post in a direction away from the ground causing the pole or post to be extracted from the ground. The frame assembly also includes an upright support member extending at an angle from the vertical frame member providing additional support thereto.Type: GrantFiled: May 11, 1998Date of Patent: August 10, 1999Inventor: Scott Loren Drane

Patent number: 5681030Abstract: A pry bar device for pulling T-type fence posts out of the ground. The device consists of an upward extending rod which may be gripped by the user. A lower end of the rod extends through an opening in a channel member and forms a U-shaped loop which welds to the bottom surface of the channel member near a front end of the channel member. The channel member has a rear end which extends beyond the rod and the front end is provided with grasping means for removably engaging the posts. The grasping means consist of two arms each adjacent to a corresponding slot. The arms and slots are parallel with a longitudinal axis of the channel member, and a central tongue separates the two slots. An upward extending tab is provided terminally on each arm and said tongue terminates rearward of said front end.Type: GrantFiled: May 18, 1995Date of Patent: October 28, 1997Inventor: Timothy Scott Nall

Patent number: 5609325Abstract: A weed pulling device includes a handle, a shaft, a blade, a step member, and a leverage member for the removal of weeds. The blade may be integrally formed with the shaft or may be attached to one end of the shaft. The shaft extends partially into the handle for attachment of the shaft to the handle. The step member and the leverage member are attached to the handle and the shaft, either singly or in combination. The blade has a forked portion for engagement with the weed and a tapered portion for facilitating insertion of the blade into the ground. The leverage member may be used for pivotal movement of the weed pulling device, for providing leverage during removal of the weed, and for compressing loose din removed during the weed removal process. The handle is sized so that a person may remove a weed from a standing position, without kneeling on the ground and with minimal bending.Type: GrantFiled: March 13, 1995Date of Patent: March 11, 1997Inventor: William L.
