It becomes a mobile drum chipper from a chipper cell arranged on a truck (1) with a drive motor, from a machine stand (2) with a chopper drum (3), a material feeder, a material discharge device, which is directed forwards and backwards in the direction of travel of the truck (1) and can work at any angle between them, as well as from a loading device (5), which works effectively with optimized axle load distribution and can be designed in many ways, which is achieved in that the chopping drum (3) via a power take-off (6) of the Drive motor of the truck (1) or its gear mechanically driven, the material intake on the right across the direction of travel of the truck (1) and the chopping drum (3) with its horizontal axis of rotation in the longitudinal direction of the truck (1) and a throwing fan (9) in the direction of travel in front of the Machine stand (2) is arranged, the axis of rotation of the throwing fan (9) being aligned axially parallel to the axis of rotation of the chopping drum (3) t.
