摘要

All the adjusting units (17,18,19,20) of the mowing machinery (1) have servo-drives (17',18',19',10') acted on with pressure fluid. The servo drives (17',18') are assigned a working and a control circulation (59, figure 13, which are controllable with a control unit together with the servo drives (17',18'). The servo drives (19',20') are assigned a working and a control circulation, which are controllable with the control unit common to one of the servo drives (19',20').
