Abstract

An agricultural machine for discharging liquid includes a boom, a frame to which the boom is fixed such that the boom can be rotated about an axis of rotation pointing in the direction of travel, an actuating cylinder for rotating the boom about the axis of rotation, and a measurement and control system for the actuation of the actuating cylinder, wherein the actuating cylinder is mechanically connected to the frame on one side. The actuating cylinder is mechanically connected to the boom on the other side for the direct introduction of force. The actuating cylinder is formed as a double-acting actuating cylinder having a piston, to which pressure can be applied on both sides in order to move the boom in opposite directions of rotation.
