Abstract
A multi-purpose agricultural implement usable in one position for cutting roots of weeds just below the surface of the ground and simultaneously therewith pulverizing the upper crust of the earth; usable in a second position for cutting a furrow of any desired width or depth in the ground of planting seeds and fertilizing; and, usable in a third position for covering the furrow. The implement is comprised of a flat blade and a handle, the flat blade being of four sided construction with opposite sides of the blade being substantially parallel. The handle is attached to the upper surface of the blade and extends in a backward direction at a sidewise oblique angle with the upper surface.
Claims1
An agriculture implement comprising:
- a flat rhomboidal blade having an upper and lower surface beveled from the upper surface to the lower surface forming parallel front and back cutting edges, and forming opposed parallel side cutting edges connecting the front and back cutting edges, said front and back cutting edges being of substantially greater length than the side cutting edges, the back cutting edge being the edge nearest a single curved tang which connects said flat rhomboidal blade with a handle extending rearwardly to an end;
- the right side cutting edge when viewed from the end of the handle toward the blade forming an obtuse angle (c) of between 100.degree. and 120.degree. with said back cutting edge;
- said single tang attached directly to the upper surface of said blade without intervening structure at substantially the center of said upper surface and forming an obtuse angle (a) of between 105.degree. to 135.degree. between the right side of said tang and said back cutting edge when viewed from the end of the handle toward the blade, said single tang being curved concavely upward toward the handle when viewed from said front cutting edge with the lower surface in a substantially horizontal plane;
- said single tang and said handle having no means for angular adjustment of said blade with respect to said handle;
- and
- the angle (b) formed between said handle and said lower surface relative to said back cutting edge ranges between 30.degree. to 50.degree..
