Abstract: Mobile apparatus, comprising a main frame and a sub-frame connected in rotatable manner to the main frame, a control cab/rollover protection and an operating arm, wherein at least one recess is provided in the rollover protection/cab, which recess provides space for parts of the operating arm.

Abstract: Articulated operating arm (100) on which one or more implements are or can be mounted, comprising substantially three articulations (101,102,103) which are pivotally connected to each other, which substantially three articulations comprise a first articulation, a second articulation and a third articulation which is intended for connection to the one or more implements, which second articulation is pivotally connected at a first end to the first articulation an at a second end to the third articulation, wherein the substantially three articulations are rotatable adjacently of each other in order to form a shortened arm, this such that during the rotation a mechanical locking of the third articulation occurs between the second and the first articulations.

Abstract: Mobile apparatus, comprising a main frame (202) displaceable on displacing means; a sub- frame (203) which is rotatable around a vertical axis and which is mounted on the main frame and provided with a control unit; at least one operating arm (210) mounted on the sub-frame and an automatically movable lifting device provided on the main frame, which lifting device is adapted to be connectable to an agricultural attachment.
