| This study investigates the performance evaluation of a portable mower for harvesting Egyptian clover. The main objective of this study is to evaluate and develop a cutter blade for the portable machine for harvesting Egyptian clover to increase its mowing efficiency. Field experiments were conducted to investigate some parameters affecting the performance of a portable mower. The tested parameters were: three cutting-blade speeds of 2500, 3000, and 3500 rpm (10.58, 12.70 and 14.82 m/s), three types of cutting blades: 2-edge, 3-tooth, and 40-tooth, plant-three intensities of ≤ 800, 800-1200 and ≤ 1200 1200 plant/m2, and plant three inclined-angles of ≤ 45°, ≤ 60° and ≤ 90° with a land plane. The obtained results can be summarized in the following points: The maximum cutting efficiency of 99.33% was obtained using a 2-edge cutting blade with a speed of 3500 rpm, plant intensity of ≤ 800 plant/m2 and plant inclined angle of 90°. Meanwhile, the minimum cutting efficiency of 88.67% was obtained using a 3-tooth cutting blade with a speed of 2500 rpm, plant intensity of ≤ 1200 plant/m2, and plant inclined angle of ≤ 45°. | ||||
