Abstract
A manually displaceable implement for ground treatment comprising a dead-man safety based on an automatic lowering and blocking of the running wheels (5). A stop (10) is provided on the implement for blockage, against which at least one lowered running wheel (5) rests. The automatic lowering of the running wheels (5) is accomplished by a two-part height adjustment rod (4), which is maintained together by an emergency release element (12). In an emergency, this emergency element (12) is activated by a ripcord, whereby the connection is automatically released.
