Abstract
A sweep is disclosed for use with an earth-cultivating implement and includes an elongated body terminating in a front nose portion. A stem is provided for attaching the body to the implement. A pair of laterally extending wing members diverge rearwardly from the body, each terminating at one end with the body to form the front nose portion while terminating at its opposite distal end in a top portion. Each wing member defines a continuous front cutting surface along its forward edge between the nose and tip portions thereof, the cutting surface being shaped in a concave curve between the nose and tip portions. Finally, each wing member further defines a continuously concave bottom surface which extends between the front cutting surface and the rear edge of the wing member.
Claims14
A sweep for use with an earth-cultivating implement, said sweep comprising:
- an elongated body terminating in a front nose portion;
- stem means for attaching said body to said implement;
- a pair of laterally extending wing members diverging rearwardly from said body, each terminating at one end with said body to form said front nose portion while terminating at its opposite distal end in a tip portion;
- and
- each said wing member defining a continuous front cutting surface along its forwrad edge between said nose and tip portions, said cutting surface being shaped in a concave curve between said nose and tip portions, and each said wing member further defining a substantially uniformly curving, concave bottom surface extending between said front cutting surface and the rear edge of said wing member.
A cultivator sweep comprising a pair of wing members interconnected at one end along a longitudinal axis to form a front nose portion and diverging rearwardly from said nose portion and said axis to terminate in distal end portions, each said wing member having a concavely curved front cutting surface extending from said nose portion to said distal end portion to provide an elongated front nose portion, and a substantially uniformly curving concave bottom surface extending from said front cutting surface to the rear edge of said wing member to provide a sharp angle between said cutting surface and the ground without creating significant elevation of the rear edges of said wings relative to said ground.
