Abstract. Cotton fiber quality begins to degrade naturally with the opening of the boll and mechanical harvesting processes are perceived to exacerbate fiber degradation. Previous research indicates that stripper harvested cotton generally has lower fiber quality and higher foreign matter content than picker harvested cotton. Results of previous work indicate that the cross auger and pneumatic conveying systems on stripper harvesters could be redesigned to help improve seed cotton cleanliness while preserving fiber quality. Thus, the cross auger trough was targeted as area for improvement. The main objective of this project was to design and test a wire belt to convey cotton laterally in a cotton stripper header. These tests included using the conveyor to convey burr cotton and testing of the modified conveyance device (wire belt) for reductions in foreign matter content and consistency in fiber quality. A laboratory test stand with a wire mesh belt was designed and built to represent one-half of an auger trough on a four row harvester. Cotton collected from an empty auger trough was tested in the test auger trough and compared through ginning results, HVI and AFIS tests to cotton allowed to be conveyed by the cross auger. The results of this test will validate if a belt conveying system is more effective and efficient at conveying cotton while removing more foreign matter and preserving fiber quality than the current auger conveyance system.
