ABSTRACT A plough has right-hand and left-hand ploughshare pairs mounted on a swing-over saddle frame extending backwards diagonally with respect to the direction of advance. The frame is supported by a 2-wheeled carriage by means of a T-frame which provides two axes of rotation perpendicular to each other. Two single-acting, swing-over cylinders are each pivoted at the bot- tom end to the T-frame on a fore-and-aft pivot axis and connected at the top end with the saddle frame. The cylinders rise upwards so that their pistons approach each other in inverted V-formation. The upper ends of the pistons work in guiding slots in plates of a guiding system fixed to a middle portion of the saddle frame and in further slots in cheek plates of a rocker. This rocker pilots on a fore-and-aft axis of the T-frame. The T-frame and/or the carriage has supports for the saddle frame in its various positions.
