The TERRA TRAC crawler track units by CLAAS Industrietechnik lead the world in agricultural technology. The soil-friendly chassis concept prepares the ground for subsequent soil cultivation, e.g. ploughless cultivation concepts, and in doing so creates high cost-saving potential. Users are convinced by the combination of high road travel speeds and excellent in-field mobility while carrying a heavy payload. Ongoing evolution of this chassis concept adds to its unique advantages and significantly widens the range of possible applications.
