However unobtrusive the finishing bar on a snowplough may appear, its effect in comparison to snowploughs without one is unmistakable. For snowploughs consisting of one or more blade segments carried by a plough frame, significant amounts of residual snow can sometimes remain after clearance. In addition, snow can be forced through the gaps in the individual blade segments, in particular if snow is cleared at higher speeds. A jet of snow can be discharged from the back, which becomes compacted on the ground as it is driven over and remains as a raised strip. This constitutes a huge safety risk.
