Abstract: Stripping harvesting emphasizes the operation of stripping before cutting. In the process of cutting, the stripping unit pushes the straws ahead and makes them fore rake. In this paper, a self-development measurement equipment was used to measure the horizontal force and the vertical force of the fore-raked straws, and the mathematic models of the horizontal force and the vertical force were obtained. The results can provide theoretical basis for the design of fore-raked straws cross conveyer.
