Ground cable laying plough blade inclination setting device - uses rotary fixings providing blade angle inclined to normal to ground surface

摘要

The inclination setting device allows the plough blade (1) to be set at an angle to the normal to the ground surface, via a rotary fixing (3, 3') between the plough blade (1) and the outrigger (5) and/or between the latter and the towing tractor (2). Pref. a rotary fixing (3, 3') is provided at either end of the outrigger (5) for rotation of the latter relative to the tractor (2) and rotation of the plough blade (1) relative to the outrigger (5), each rotary fixing (3, 3') having its axis extending in the travel direction of the tractor (2). USE - for ploughing vertical trench in inclined ground.
