All the lawn mowers I've seen at least have a safety mechanism where they stop as soon as you let go of the handle. And the dangerous parts are shielded on all sides during normal operation. The peloton in the video has no protection to prevent dragging something underneath it, and just kept going as it dragged the kid under it. The motor stalled, locking the kid, then started dragging again as soon as the kid managed to almost get free.
