Abstract

This study aims at investigating the realities of tractor rotary tilling and paving operations performed by farm families in the central part of the country, measuring the power requirement so as to find the energy-saving factors for tractor rotary tilling, and designing a device to prevent soil adherence to the inside of the rotary cover-this part is the most subject to soil adherence and affects the power requirement. As a result of rotary tilling tests using rotaries equipped with a soil adherence preventer, the power requirement values were measured to be 52.18, 52.44, 49.01 and 46.34 PS for general, stainless steel, rubber and PE rotaries, and as a results of measurement of the quantities of the soil adhered to rotaries after their tilling tests, on the average, the quantities were measured to be 5.6, 5.7, 3.1 and 2.7kg for general, stainless steel, rubber and PE rotaries, respectively. The PE rotary cover reduced the power requirement and soil adherence by 11 and 52%, respectively.
