Abstract
Abstract A device for selectively engaging weed plants at their ground or below ground level, securing the stem or root thereof and levering the plant, roots and all, from the ground. Jaws of the device engage the plant stem in a narrowing wedge configuration without severing the plant stem and, as the plant retracting lever action is applied, the jaws are cammed closer together further securing the plant stem therebetween and permitting the operator to withdraw the plant from the ground.

Claim 1
Independent Claim
149 words
Apparatus to extract plants and weeds from the ground comprising plant stem engaging and holding means having a first and second blade means operably connected to open and close in scissors-like fashion, said first blade means defining hook-shaped plate means adapted to overlap said second blade means to define a triangle shaped opening between said blades, both said blade means adapted to surround and engage the plant stem to be extracted; fulcrum means operably attached to said plant stem engaging and holding means, said fulcrum means adapted to rest upon the ground; and lever means attached to said fulcrum means whereby when said blade means opens and closes in scissors-like fashion, a narrowing closed triangular shaped opening between the blades is created to hold the plant stem in order that the plant may be levered out of the ground by rotating the lever handle means about the fulcrum means.
