Yes. Rubber blade and stabilising wheels. No sensors.
even tractors and power ploughs use sensors and satellite positioning to map the field and store all the information via an on board computer. so the next time its done they lay of the land is already stored and the depth ect is done via the GPS and stored info. I've worked on plenty of snow ploughs , they drop them down onto rollers , the rubber strip is to take into account any imperfections in the road surface
