60 Robust and proven. RU 450 and CONSPEED. RU 450: up to 4.50 m working width. The crop flow concept is based on three large cutting and transport discs rotating counter-directionally to each other. The cut surfaces of the plants rest on the blade and create a self-sharpening effect as they are fed in. An aggressive crop flow is ensured by the intake auger whose speed can be optimized in line with the set chopping length. The simple construction makes for ruggedness and reliability and has proven itself remarkably well. • Low power requirement • Reliable crop transport under all conditions • Can be switched on and reversed under full load • Adapts easily with quick coupler
