In this part, field experiments were conducted to confirm the results obtained from the soil bin experiments and also to examine the difference of force and soil failure caused by single and multiple tines. It was indicated that the results from soil bin and the results from field experiments gave a good agreement. It was cleared that the specific draft of multiple tines was smaller than that of single tine. The increment of the specific draft of multiple tines due to increase in working speed was also smaller than that of single tine. The soil pulverization was measured by means of image processing. The results were confirmed that the soil pulverization rate of spring-tine was higher than that of rigid tine.
