ABSTRACT:
The invention refers to an implement regulating device in an agricultural machine including at least one group of implements (4) arranged across the driving direction, thereafter cross-wise arranged support members (15) and at least one each group of implements and support members are controllable and adjustable by a power device (23). Implements (4) and support members (15) in each group are journalled in bearings at one end of at least one carrying arm (13). The power device (23) is adapted to rotate a cross-running main beam (19). The main beam is connected with the carrying arm (13) via a spring member (18) and is rotatably suspended in relation to the frame (Ia) of the machine (1). Activation of the power device is adapted to influence the carrying arm between a position for maximum sowing depth and a transport position.
