Abstract
An implement for agricultural machines which is attachable to a tine of such a machine. The earth engaging portion includes steeply inclined side faces 11 and an inclined point 10 with a protrusion 14 which assists in directing work flow. The relatively flat portion 12 lies above the side faces 11 between them and the shaft portion 8 which is attachable to the tine. These implements are formed from conventional implement blanks and the height of the side faces is the same as that of conventional implements but the angle of inclination is greater.
Claims6
An agricultural earth engaging implement including a shaft and an earth engaging portion which comprises a point with two swept back leading edges extending from said point, an inclined face extending from said point and leading edges inclined at an angle of from about 25.degree. to 45.degree. to the horizontal, said inclined face extending to an intermediate section and an elongated protrusion extending from said point toward the base of said shaft when assembled therewith and terminating on said intermediate section, said protrusion formed by indentation of the undersurface of said earth engaging portion, said intermediate section being planar, parallel to said leading edges, and defining an acute angle no more than 10 degrees relative to the plane containing said leading edges, said intermediate section being located forwardly of said shaft and extending along parallel to said swept back leading edges between said shaft and said inclined face.
