The verge mower is perfect for near roadside mowing work, either right-hand or left-hand operation. Due to its low height, this mowing device is suitable for use underneath crash-barriers. The speed for evasive movements when approaching an obstacle can be adjusted continously at the control unit. An automatic pressure relief system minimises the ground pressure of the mowing head. The special construction of the safety mowing shaft reduces danger of ejected material to a minimum.
