Abstract

The agricultural machine, with working sections (5,7) stacked in the direction of travel, are operated by pressure cylinders (12,20) through a pressure switch system (21). A reversing valve (23) gives two settings where, in one setting, the working tools (5,7) are lifted in a set time sequence and, in the other setting, they are lowered in the same time sequence. A barrier valve (26), normally open, is closed at the inlet side on a low switching pressure of 3 bar. A second barrier valve (27), normally closed, is opened at the inlet side by a higher switching pressure of 100 bar.
