The fatigue life of combine reaping knife was evaluated in this paper. The combine reaping knife is an important part of a combine, which is a very complex reaper. Firstly, the experimental measured strains were obtained under two different conditions ; in the barley field outside and indoor circumstance. Secondly, FEM was held using software ANSYS 5.3. Load and boundary condition of FEM was applied through experimental data. Then the experimental data and the FEM analysis result were applied to evaluate the fatigue life based on stress-life method. The result was that the fatigue life of combine reaping knife was about 200-300 hours.
