Revolutionizing Rock, Clod, and Foreign Material Separation
Since 1999, Richard Bishop, P.E., owner of BishTec, has led innovations in agricultural machinery—starting with John Deere IVT and Spudnik Planters. The Sand Machine continues this legacy by exceeding performance standards in rock, clod, and debris separation.
Compared to modern air and vacuum machines, the Sand Machine delivers up to 15% better separation. Proven since 1985, it reduces processor penalties from foreign material contamination—saving farms potentially hundreds of thousands of dollars annually.
