摘要 |
<p>The farm machine has blocking mediums attached at an excavation cylinder for blocking of a pressure medium outflow from the excavation cylinder. The blocking arises during down-nodding of lateral frame sections (12,13) with the ground adjustment. The blocking mediums are operated by a forward control unit during lifting of a cultivation rack (2) in a forward position. The excavation cylinder is retractable and extendable in lower operating position, so that the lateral frame sections are nodded upward and downward for ground adjustment of working tools arranged at the cylinder.</p> |
