Over the years, Groff Tractor has developed strong relationships with our manufacturers and has consistently offered a wide range of the highest quality construction equipment. Groff Tractor is one of the leading CASE construction dealers in the country and we supplement our CASE products with some of the other leading manufacturers in the world, such as Takeuchi, Liebherr, Terramac, Terex, Wirtgen, Vögele, Hamm, Kleemann, and Rubble Master. A lot has changed since 1958, but one thing that remains the same is our commitment to our customers.
