ABSTRACT:
A process for producing an agricultural sweep defining upper and lower major surfaces and having a predetermined shape including an earth engaging pointed head portion with a pair of wings symmetrically diverging rearwardly and generally horizontal from a nose region. Each wing has a bevel-like configuration on the upper surface of the sweep and an attachment portion integrally formed with and extending upwardly and rearwardly from the head portion. The unique process of the present invention begins with providing a planar preformed blank having a developed shape of the cultivator sweep. Thereafter, the blank is heated to an elevated temperature. The blank is thereafter loaded into a forming die set including first and second cooperatively arranged forming dies. One forming die is configured with a mirror image of one side of the cultivator sweep and the other forming die is configured with the opposite major side of the cultivator sweep. The complete and finished shape of the agricultural sweep is formed in a single press cycle from the blank.
