Self-propelled multiple-purpose agricultural machine with displaceable driver's cabin

A self-propelled multiple-purpose agricultural machine, particularly a tractor, comprising a chassis;

• a driver's cabin movable relative to said chassis between at least two working positions and lowerable to a third lower transporting position;
• at least one machine axle connected with said chassis and located at a predetermined height above a ground level;
• an auxiliary frame detachably mountable on said machine axle when the machine is to be transported and supporting said driver's cabin when said driver's cabin is lowered from one of said working positions to said third transporting position so that said driver's cabin becomes located in a supporting plane substantially at a height corresponding to the height of said machine axle;
• and a plurality of control elements extending from said driver's cabin, said control elements being formed so and having a length such that their connection with respective parts of the machine is guaranteed and does not need to be interrupted even when said driver's cabin is lowered to said third transporting position so that for transportation with said lowered cabin the machine can propel itself.
