A weed puller that comprises a plurality of prongs positioned about an axis, an anvil plate, and a moveable mass adapted to be driven into the anvil plate so as to transmit a force through the anvil plate to the prongs where the force has a substantial component in line with the axis about which the plurality of prongs are positioned. In a preferred embodiment, the weed puller comprises a body having a cavity that terminates at the anvil plate with the moveable mass slideably positioned within the cavity and the moveable mass being coupled to a rod that extends out of the cavity from an end opposite the anvil plate.
1. A weed puller comprising:
a plurality of prongs positioned about an axis;
an anvil plate coupled to the prongs;
a moveable mass detached from the plurality of prongs;
a body having a cavity that terminates at the anvil plate; and
a rod attached to the moveable mass and extending outside the cavity, the rod controlling the movement of the moveable mass within the cavity;
wherein the moveable mass is slideably positioned entirely within the cavity to directly strike the anvil plate.
2. The weed puller of claim 1 wherein the anvil plate is positioned between the moveable mass and the plurality of prongs.
3. The weed puller of claim 1 comprising three prongs extending from a surface of the anvil plate opposite the moveable mass at points that lie on or adjacent to the vertices of an equilateral triangle.
4. The weed puller of claim 3 wherein the three prongs are elongated and fixed in position relative to each other and have center lines that are substantially parallel to each other.
5. The weed puller of claim 4 wherein the body comprises a center line and the prong center lines are substantially parallel to body center line.
6. The weed puller of claim 5 wherein the moveable mass is slideable along the center line of the body.
7. The weed puller of claim 6 wherein the body is between 16 and 48 inches long, has walls between 1/64 and ½ inch thick, an internal diameter of between ½ and 4 inches, and an external diameter between ½ and 5 inches.
8. The weed puller of claim 1 further comprising handles positioned adjacent to an end opposite the anvil plate that project outward from the body by 0 to 18 inches.
9. The weed puller of claim 1 wherein the rod comprises a grip positioned opposite the moveable mass, and with the moveable mass against the anvil plate the grip projects outward from the body by 3 to 12 inches and includes finger contours.
10. The weed puller of claim 1 wherein the rod has a length of 7 to 48 inches and is formed from a cylindrical rod having a diameter of 1/16 to 4 inches.
11. The weed puller of claim 1 wherein the moveable mass is a cylindrical mass having a diameter slightly smaller than the internal diameter of the body, a length between 1 and 30 inches, and a weight of ¼ to 10 pounds.
12. The weed puller of claim 3 wherein the three prongs are positioned at the corners of an equilateral triangle having sides between ½ and 10 inches long, and the prongs having a length between ½ and 14 inches.
13. The weed puller of claim 1 further comprising two circular plates, one of the plates being the anvil plate, welded to the ends of a pipe forming the body and retaining the moveable mass within the body where the moveable mass is a cylindrical mass coupled to a rod extending through a hole in a plate of the two circular plates that is not the anvil plate.
14. The weed puller of claim 13 wherein the anvil plate has a diameter at least 1 inch greater than the diameter of the body.
15. The weed puller of claim 1 further comprising foot bars attached to the body and positioned adjacent to the anvil plate.
16. A weed puller comprising:
a plurality of prongs positioned about an axis;
an anvil plate attached to the plurality of prongs;
a body having a cavity that terminates at the anvil plate;
a moveable mass detached from the plurality of prongs and adapted to be driven directly against the anvil plate so as to transmit a force through the anvil plate to the prongs where the force has with a substantial component in line with the axis about which the plurality of prongs are positioned and in a direction that the plurality of prongs point; and
a rod attached to the moveable mass and extending outside the cavity, the rod controlling the movement of the moveable mass within the cavity.
17. The weed puller of claim 16 further comprising foot bars attached to the body and positioned adjacent to the anvil plate.
18. The weed puller of claim 16 wherein the rod comprises a grip positioned opposite the moveable mass.
