Abstract

A self-propelled multiple-purpose agricultural machine, particularly a tractor, has a chassis, a driver's cabin movable relative to the chassis between at least two working positions and lowerable relative to the chassis to a third low position, at least one machine axle connected with the chassis and located at a predetermined height above a ground level, auxiliary frame connected with the machine axle and supporting the driver's cabin so that its supporting plane is located substantially at the height of the machine axle, and a plurality of control elements extending from the driver's cabin and formed of such a type and with such a length that the connection of the control elements with respective parts of the machine is guaranteed and does not need to be interrupted even when the driver's cabin is lowered to the third low position onto the auxiliary frame.
