Evaluation of adjustable tine wings under soil bin conditions

Abstract

Recently, the demand for tillage tools that meet most field needs has increased dramatically under various conditions. A tine with the feature of adjustability has the potential to achieve this goal. Therefore, adjustable tine wings with different wing widths are evaluated in this study with speeds of 1.1 and 3.3 m s-¹ under soil bin conditions. The results showed that the speed and the wing width have a significant linear effect on horizontal and vertical forces, while the speed has a much higher impact than the wing width on forces requirement. The horizontal force increases with increasing wing widths, whereas the vertical force decreases with increasing wing widths.
