ADAM – Hydraulic tilting of the mulcher by gear tracking with PTO shaft alignment. With the W-shaped angles the range of motion increases and the mulcher can be moved up- and downwards even higher. This angular adjustment protects the PTO shaft and the input shaft even at high loads and supports an ideal adaptation to the conditions of the roads. Advantages: longer service life of PTO and input-shaft, even deeper digging, working with an hydraulic alignment system is easier and faster.

Available working width: 200, 225, 250 cm [79″, 89″, 98″].
