A mobile apparatus includes a main frame with displacing means, a rotating sub-frame rotatably connected to the main frame such that the sub-frame is rotatable around a rotation axis relative to the main frame, and a working arm connected to the sub-frame. The sub-frame includes a standing or seating position for an operator. The working arm includes at least two arm segments, and a first arm segment of the at least two arm segments is pivotally connected to the sub-frame around a pivot point located at a distance of the rotation axis. The first arm segment and the sub-frame are configured such that the first arm segment can be moved rearwards onto the sub-frame in the direction of the rotation axis to a rearward position in which the first segment extends over the rotation axis.
