Abstract: In order to solve the problems of grain losses in integral type reciprocating cutterbar when reaping ridge culture soybean, after the analysis of allterrain reaping unit equipped with sectional type reciprocating cutterbar and two degree of freedom profiling mechanism, cutterbarridges profiling force mathematical model was established. A method to solve extreme value of profiling force was presented to fermat theorem. The maximum and minimum ridge pressure were evaluated on band knife cutting machine under working condition. These were 102.84N and 32.28N respectively. The experiment results show that the average cutting is 43.7mm, total losing factor of reaping apparatu is 1.90%, which indicates that the working quality standard request has been reached, the average and total losing factor of sectional type reciprocating cutterbar are better than integral one.
