  • Sensor for automatic steering system for row-crop harvester
    Patent number: 3991618
    Abstract: A row-crop harvester adapted to travel along the ground in a transport direction is provided with four crop sensors. One crop sensor is provided to one side and in front of the harvester and normally feels the edge of the crop in front of the harvester and generates an output that controls an automatic steering system which guides the harvester along this edge. Another sensor is provided at the back of the harvester on the other side from the front sensor and serves to feel the edge of the swath just cut. Another sensor in front of the cutter on the harvester detects a gap in the crop and serves to switch the automatic steering system over from the front sensor to the back sensor in case a gap appears in the crop so that the harvester will not swing back and forth to follow minor crop gaps. In addition another sensor is provided on the front of the harvester so that when it arrives at the end of the field the harvester is automatically stopped and can only be moved by manual takeover of the steering.
