DISCO mowers from CLAAS are some of the most fuel-efficient, durable, agile mowers in the market. The DISCO 4000 TRC was designed specifically for North American crop conditions with a double roller drive to better handle taller crops, a new drawbar attachment for smooth turning, and adjustable swath plates for more flexibility in windrow formation. The DISCO 3600 TRC / TC and 4000 TC built from the same architecture provide wide working widths in an easy to hook up and operate package. All these mowers cut cleaner because they come standard with the ACTIVE FLOAT hydropneumatic suspension and PROFIL pivot linkage, unlike anything found on competitive trailed mowers. Adjustments to the suspension can be carried out while operating through changing field conditions.
