Abstract
A rotary cutting system for use with a row crop harvesting apparatus includes a pair of contra-rotating sickle assemblies operating in conjunction with a system of flexible, toothed crop-gathering belts. Each sickle assembly includes at least a pair of multi-toothed sickle blades arranged to cooperate with a stationary cutting member. As the belts are driven to gather in crop material, the sickle blades function to sever the material near ground level, the two sickel assemblies being arranged to operate simultaneously on two adjacent rows of crop material. Mirror-image construction of the sickle assemblies permits use of sickle blades having multiple, double-edged teeth such that the blades can be interchanged between assemblies for optimum blade utilization. The stationary cutting member is also of double-edged construction and is mounted for reversible operation. The multi-toothed rotating blades are mounted on a circular blade support member and each blade covers about half of the area thereof such that the blades mounted side-by-side provide a continuous 360.degree. pattern of cutting teeth. Each adjacent pair of teeth in the 360.degree. pattern includes two mutually parallel c…
