The authors studied on the load factor of small type tractor to get data for deciding the strength of body. Therefore, we produced the accelerometer to determine the load factors and measured the accelerations of tractor body under various speeds, tillage-depths, and speeds of rotary shaft. The load factors were 1.5-4 and they were larger at the front of body. Thus, the great stress magnitudes appeared between the wheel axis and the hitch.
