Abstract

A weed extraction tool includes an actuator having two parallel blades formed from a single piece bent into a u-shape. The blades have serrated leading edges and a deep notch in the upper third of the blade trisection above the serrations to facilitate extraction of undesired plants.

Claims (20)

1. A weed extraction tool comprising:

an operator handle; and

a fixed actuator attached to said handle comprising first and second blades extending away from a central bight portion, wherein said blades are generally parallel and are spaced apart a distance from each other, wherein each of said blades is generally planar, wherein each of said blades comprises a leading edge and a trailing edge, wherein said leading edge is generally linear and comprises serrations, wherein said leading edge comprises a horizontally oriented “U” shaped notch in the upper third of the blade, said notch configured to capture and extract roots of weeds, wherein said “U” shaped notch has a depth of at least three times a depth of one of said serrations.

2. The weed extraction tool of claim 1 , wherein said leading edge on said first blade is oriented in a direction opposite said leading edge on said second blade.

3. The weed extraction tool of claim 1 , wherein said actuator and blades are contiguous and formed from a single piece of metal.

4. The weed extraction tool of claim 1 , wherein said operator handle comprises a stem portion and a horizontal grip affixed in a T-shaped configuration at an upper end of said stem.

5. The weed extraction tool of claim 4 , further comprising a plunger operable to extend and retract within said stem.

6. The weed extraction tool of claim 1 , wherein the trailing edge is curvilinear.

7. The weed extraction tool of claim 1 , further comprising a foot plate attached to the handle.

8. The weed extraction tool of claim 1 , wherein the leading edge is generally vertical.

9. The weed extraction tool of claim 1 , wherein the trailing edge extends in a continuous arc.

10. A weed extraction tool comprising:

an operator handle;

a foot plate attached to said handle; and

a fixed actuator affixed to a lower end of said handle, said actuator comprising a parallel set of spaced apart blades extending away from a central bight portion, wherein each of said blades is generally planar, each of said blades comprising a leading, serrated edge, the leading, serrated edges of the blades directed in opposing directions, wherein said leading, serrated edge is vertical and linear, wherein each of said blades comprises a trailing edge extending in a continuous arc, and wherein said leading, serrated edge comprises a horizontally oriented “U” shaped root extraction notch in the upper third of the blade trisection, wherein said “U” shaped root extraction notch has a depth of at least three times a depth of a serration in said leading, serrated edge.

11. A weed extraction tool comprising:

an operator handle comprising a stem portion and a horizontal grip portion in perpendicular relationship;

a foot plate attached to a lower end of said handle; and

a fixed actuator attached to said handle adjacent said foot plate, said actuator comprising a parallel set of generally planar blades extending away from a central bight portion, wherein said blades are spaced apart a distance from each other, wherein each of said blades comprises a leading, serrated edge, oppositely oriented from the leading, serrated edge on the other blade, wherein said leading, serrated edge comprises a horizontally oriented “U” shaped notch in the upper third of the blade trisection, wherein said leading, serrated edge is generally linear and vertical, and wherein each of said blades comprises a curved trailing edge, wherein said “U” shaped notch has a depth of at least three times a depth of a serration in said leading, serrated edge.

12. The weed extraction tool of claim 11 , further comprising a plunger extending through said stem, said plunger operable to dislodge an extracted plant from said tool.
