Agricultural insert

An agricultural tool for forming a furrow comprising an essentially syncline shared slicer having a leading member, a trailing member and a pair of sides tapered from said trailing member toward a sharp convex cutting edge extending longitudinally upwardly and forwardly from said trailing member toward said leading member, a leading deflector extending upwardly and forwardly from said cutting edge and formed integral with said slicer by a mounting web, said mounting web having a pair of sides extending rearwardly from said leading deflector and expanding to a heel having first and second sides adjoining respective sides of said syncline shaped slicer and a rear portion, each of said first and second sides having formed therein a notch extending longitudinally forwardly from said rear portion of said heel and having formed therein a cavity below said notch containing a wear insert said cutting edge including a slot having secured therein a cutting insert comprising an elongated wedge shaped member including a leading end;

• a trailing end of a generally triangular form;
• a first side surface and a second side surface contiguous therewith extending longitudinally from said trailing end to said leading end and defining a lowermost edge including a substantially linear portion adjoining a sloped curvilinear front portion;
• and a top surface between said first side surface and said second side surface extending linearly from said trailing end to said leading end and having a contour which converges from said trailing end to form a V-shaped leading end.
