US Patent Number
The present invention is directed to an easily adjustable, semi-floating, self-steering cutter head for row crops. The present invention incorporates self-steering capabilities, a cut-off mechanism and a quick-adjustment into a single integral unit. 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 present invention is particularly useful in harvesting tobacco.
