The Illinois Tractor Co. of Bloomington, Illinois (USA) started out building grain silos, but subsequently entered the tractor market with several motor cultivator designs from 1916 onwards. In 1919 they introduced the 18-30 "Super Drive" model, with a four-cylinder engine fully encolsed by sheet metal. The 18-30 was joined by a larger 22-40 model in 1920. In Canada, the 18-30 was sold by the Robert Bell Co. of Seaforth, Ontario as the "Imperial Super Drive".
