FAE MTH 225 and a Fendt 936 tractor at work on Highway A7 in Germany — hard rock terrain — crushing stones into granulometry 0-63mm in a single pass, with a working depth of 0.35 m and a working width of 2.3 m. The Water Spray System (WSS) prevents teeth from overheating while shredding, reducing wear and tear and improving efficiency over the long term. The WSS was also designed to provide the required soil moisture for the binding agent, with precise regulation of the water injected. Additionally, using the WSS means mulching and/or mixing and dampening can be completed in a single pass.
