In order to investigate the fatigue life of tractor PTO＇ s passive gear under the actual technics, the fatigue experiments were performed by syntonic high-frequency test-bed. The tractor PTO＇ s passive gear was selected at random,and the bending fatigue tests were done. The gear＇ s fatigue life limit and S-N curve were gained. The experimental data can be acted as the data for the tractor gear＇ s reliable design and the construction of the model for evalu;,ting life.
