US Patent Number
A two row harvesting aid including an easily adjustable, semi-floating, self-steering primary cutter head and an auxiliary second row attachment for harvesting row crops. Self-steering capabilities, a cut-off mechanism and a quick-adjustment are combined into a single integral unit on the primary harvester. Direction sensing is accomplished by utilizing a feeler arm or a set of feeler arms which follow the plant stock row or other protrusions or indentations. Forces detected by the guidance sensors are transmitted to a ring which is a part of the housing and/or shielding of the cut-off device. The steering forces may be transmitted to a steering system through a single connection. The auxiliary second row attachment includes a motor operatively connected to an auxiliary cutter head for simultaneously harvesting an adjacent row of crops.
