Kakahy, Amer Najat Najmaldeen and Ahmad, Desa and Hamid, Md. Akhir and Sulaiman, Shamsuddin and Aris, Ishak (2012) Effects of knife angles and cutting speeds on pulverization of sweet potato vines. In: USM-AUT International Conference (UAIC) 2012, 17-18 Nov. 2012, Bayview Beach Resort, Penang, Malaysia. (pp. 45-50).


A study was conducted to investigate the effects of three different knife angles (30, 40 and 50°) and three different speeds (1830, 2066 and 2440 rpm) of a Mower on sweet potato vine slashing (pulverizing) The results showed that all the treatments were significant at 99% significance level on the percentage of pulverized vines. The best results were for the first knife angle (30°) with the lowest vine pulverized of 57.59%. The third speed (2440 rpm) had the best vine pulverized percentage of 54.00%. The best performance for overlapping effect between knife angle and speed of mower was achieved by the 30° knife angle at 2440 rpm with average vine pulverized percentage of 38.73%.
