ABSTRACT:
A blade construction for a cultivator blade or a cultivator sweep, wherein the blade is adapted to sever plants from the ground by digging up the roots, to permit collection of the plants and subsequent separation of the fruit contained thereon. The blade includes first and second elongated body portions that have respective upper surfaces that are disposed relative to each other to define an obtuse included angle. The forward body portion includes a cutting edge that extends longitudinally of the blade, the cutting edge defined by the intersection of the upper planar surface of the first body portion with a longitudinally-extending grinding surface that is oriented at an acute angle relative to the forward upper planar surface. The obtuse included angle between the first and second body portions can range from about 150.degree. to about 170.degree., and the acute angle at the grinding surface can range from about 25.degree. to about 35.degree..
