For fast and precise working depth adjustment, PÖTTINGER has equipped the TERRIA trailed stubble cultivator with a high quality hydraulic system as standard. This supplies the hydraulic cylinders on the jockey wheels and rear roller with the same ratio of oil. As a result the machine is always exactly parallel to the ground. The settings can also be changed while driving. A large, easy-to-read scale at the front end of the frame provides a quick check.
