ABSTRACT:
A manually displaceable implement for ground treatment comprising a housing (1), a rotor drum (2) rotatably maintained therein and driven by a motor, a connecting piece (3) and height-adjustable running wheels (5). In the non-operating state, the running wheels (5) are lowered, so that the rotor drum (2) is raised off the ground (B) to be treated. In the process, at least one running wheel (5) rests against a stop disposed on the housing (1) and is blocked in this manner. The implement for ground treatment is secured by this blocking means (10) and does not make any uncontrolled movements, even if the drive motor of the rotor drum (2) is switched on.
