  • Patent number: 6904977
    Abstract: A portable handheld work apparatus, such as a motorized cultivator (1) or the like, includes a frame (2) which extends essentially in the longitudinal direction (21) of the work apparatus. A drive motor (3) is fixed at one end (22) of the frame (2) and a work tool is driven by this drive motor. The opposite-lying end (23) includes at least a handle (7, 8) for guiding the work apparatus during the operation thereof. In order to make possible an ergonomic work posture of the operator, the handle (7, 8) lies facing away upwardly from the ground surface (42) in the work position of the motorized work apparatus. The work position is a position in which the work tool lies on the ground surface (42) to be worked.
