Twin City tractors



Twin City tractors were built by the Minneapolis Steel & Machinery Company until 1929 when it merged with the Moline Implement Company of Illinois and the Minneapolis Threshing Machine Company of Hopkins, Minnesota.

Twin City tractors were dark gray in color, and had a logo much like the "TC" that the Minnesota Twins baseball club uses.
