LEMKEN’s Zirkon 12 rotary harrow is designed for maximum continuous loads for both conventional and conservation tillage. The active tools of the Zirkon 12 produce an intensive mixing and crumbling effect to about 15 cm working depth and thus prepare an optimal seedbed in virtually any soil conditions. The intensity of cultivation can be precisely controlled via the forward travel speed, the PTO speed and the rotary harrow gearbox.
