After twelve years of development, it was introduced into the market. That original design remains the basis for today’s Grouser track systems—accepted by many as the #1 over the tire track available. In 1978, Grouser brought its first dozer to the tractor market. Today, Grouser remains one of the few manufacturers of big 6-way hydraulic dozers for 2WD tractors, 4WD tractors, and skid steer loaders. Our 20,000 square foot facility was built in 1997 and expanded to 40,000 sq. ft. in 1999 with the growth of demand for our products.
