GBT Industries manufactured compact tractors in the mid 1970s in Madison, Wisconsin. GBT was founded in 1975 by Jerry Boesch and Jim Gnewuch. The GBT-2000 model was a cultivating tractor designed after the Allis G. Model GBT-3000 and GBT-4000 were utility tractors, although it appears the 4000 may never have entered production. By 1978, tractor assembly stopped and the company was a distributor for imported Pasquali tractors.
