Abstract: Abrasive wear is one of the most critical problems encountered by tillage tools, as it significantly affects their efficiency and increases production costs. This study experimentally investigated the wear behaviour of three chisel plough blades made of steel with different chemical compositions, available in the local market of different origins. The experiment was conducted using a soil bin at 19 rpm speed, 100 mm depth and 30° penetration angle, in dry sliding conditions for 30 hours. Results showed that the highest cumulative wear reached 9.34 g and the highest wear rate reached 0.226 g/h for blade B3. In contrast, blade B1 experienced the lowest cumulative wear of 5.49 g and the lowest wear rate of 0.130 g/h over the same period. The wear rate initially was the highest, then gradually decreased and remained approximately constant towards the end of the test. The results also indicated that dimensional reduction had occurred. Blade B1 showed the lowest reduction (length and width), reaching 3.76 mm (3.6 %) and 0.85 mm (1.2 %), respectively, while blade B3 showed the greatest reduction, reaching 4.9 mm (4.7 %) and 1.75 mm (2.5 %), respectively. However, the thickness reduction for each blade varied with its location. The blade tip showed the most significant thickness reduction, followed by the outer and inner edges.
