A ground manoeuvering device comprises a housing with a fastening device for the skid, a hydraulic apparatus as well as an outer wheel and an inner wheel on two aligned horizontal axles on the hydraulic apparatus, respectively one on the inside and one on the outside beside the skid. The hydraulic apparatus comprises an extendable piston and an engagement shaft with a lever attached in a swivellable manner. When the lever is rocked, the piston is extended from the hydraulic apparatus and thereby lifts the housing vertically upwards. The engagement shaft is aligned in the wheel running direction and the lever extends, in the operating state, in the wheel axle direction of the outer wheel. In addition, the lever comprises a tread section, in order to raise the fastened skid onto the two wheels using the hydraulic apparatus while standing conveniently beside the helicopter repeatedly stepping with the foot on the tread section.
