The Vassar Company, located in Perkins, Oklahoma, is an equipment manufacturer for the farm and small-scale construction industries. A number of their products are versatile enough to be used by landscapers and acreage owners, and for agricultural and industrial purposes. They rely on distributors and equipment dealers to sell their products, doing very little marketing in-house. The company was founded in 1940 by I.D. “Jack” Vassar, and is managed today by Jack’s son and granddaughter, Jack K. and Jacque Vassar. The Vassar Company (Vassar) is known for their well-crafted equipment, and is looking to expand into other markets.
