To Measure Tractor Driving Wheel' s Load at Bearing

In order to acquire the tractor driving wheel load easy, a new type of driving axle to measure the bearing's load which is a reflection of the driving wheel' s load. The load time history of plowing tractor' s driving wheel' s was measured using this method. The correlation of the load to tillage resistance and load' s PSD (Power Spectral Density) was obtained.
