Safety is of prime importance The ts125 plough blade has a patented safety mechanism. If the plough blade encounters an obstacle, e.g. an obviously protruding manhole cover, an overload safety mechanism is activated. The blade tilts away from the danger area, practically without expenditure of energy. The peak load is reduced to a minimum, in comparison to plough blades that are prestressed by means of suspension. Crash tests conducted show that the driver was hardly aware of the obstacle.
