ABSTRACT:
A ground-boring device with a ground auger, which features a boring spindle driven by an engine-transmission unit. A framework is provided with a travelling gear. On the grip ends of the framework is provided a handgrip arrangement located during operation of the device at roughly the gripping level of a service person and a seating device for mounting of the engine-transmission unit of the ground auger, arranged in a longitudinal direction to the framework at a horizontal distance from the travelling gear. The handgrip arrangement is positioned such that the boring spindle essentially runs vertically so that the seating device permits a swinging of the ground auger in relation to the longitudinal direction of the framework during its penetration into the ground.
