This morning slipped in the district Altenessen a mower on Zweigertbrücke the Emscher dam. Due to the relatively softened by flooding soil and the steep terrain threatened the tractor, which is equipped with a special arm, to sink in the Emscher. The driver sought with the arm stop in the ground to stabilize his position. Shortly before the water surface, the tractor could be secured by experts of the fire department with three steel cables. The mower was successfully recovered after a few hours.
