Effects of Tilt Angle on the Performance of Disk Plough in Silty-Clay Soil

Abstract

The standard disk plough is an essential component of Iraq's conventional farming method. The tilt angle between the planes of the disk's cutting edge, which is tilted to a vertical line, can be adjusted depending on the conditions of the field. Tractor operators occasionally utilise an angle close to the optimum to reduce the depth of tillage and, therefore, energy consumption without taking tillage consistency and the effect on soil properties. This study was carried out at Al-Mussaib Technical College to examine the impact of three tilt angles (15°, 20°, and 25°) on the density of soil bulk, Draft Force, wheel slippage, and field quality with a potential forward speed of three and a depth of two (20,30cm). The findings revealed that changing the plough tilt angle improved the Bulk density, draft force, and field productivity substantially (p0.05), but there were no noticeable findings for the slippage of the tractor wheel.
