Saukville Tractor was organized in Wisconsin in 1993, building cultivating tractors in the style of the Allis-Chalmers G. Saukville Tractor was dissolved in 2008 and it appears to have been acquired by Norco Equipment. Norco was acquired by Barko in 2012. Production of the Saukville appears to have stopped around 2010.
