Studies on Tilling Characteristics of PTO Driven Disk Tiller (1)

Power Requirement and Side Force Study

Abstract

Quantitative evaluation of tilling characteristics of a PTO driven disk tiller was made by investigating power requirement and specific work under varying ground speeds of the tractor. It was found in the field tests that in comparison with rotary tiller, the energy efficiency of the PTO driven disk tiller was higher especially for high tractor ground speed. The side force acting on a disk blade was successfully measured to find the relationship to the tractor ground speed. Also the soil reaction acting horizontally to the rear wheel was measured to find that the rear wheel was functioning to provide horizontal force which counteract the side force acting to the disk tiller from the soil being inverted.
