High shoulder planer S70 is used to reduce high way/roads shoulder and unable drainage to ditch. 

The S70 roadside can be attached to the DSL and cleans the road shoulder, eliminating the soil that has accumulated over time, hindering the regular flow of water during rainfall. 
The soil is discharged to the side with a helical cutter; the same device can be used for cutting and creating a small channel to facilitate water drainage
