Effects of cutting speeds, moisture contents and sweet potato varieties on tractor fuel consumption


Kakahy, Amer Najat Najmaldeen and Ahmad, Desa and Hamid, Md. Akhir and Sulaiman, Shamsuddin and Aris, Ishak (2016) Effects of cutting speeds, moisture contents and sweet potato varieties on tractor fuel consumption. In: 3rd International Conference on Agricultural and Food Engineering (CAFEi 2016), 23-25 Aug. 2016, Seri Pacific Hotel, Kuala Lumpur, Malaysia. (pp. 66-70).


A study was conducted to test the effects of three mower cutting speeds (2300, 2500 and 2700 rpm), three varieties of sweet potato (VitAto, Orange and Stone) at three different moisture contents of the plant (22.4, 30.39 and 41.06 %), wet base (wb %) on tractor fuel consumption (ml/m). The results showed that all the treatments were significant at p ‹ 0.01 significance level for fuel consumption (ml/m). The best fuel consumption of 1.49 ml/m was achieved when using the Stone variety of sweet potato at 22.4 % moisture content and 2300 rpm mower speed. Data were analyzed statistically using ANOVA and the least significant difference LSD calculated at 1 % to estimate the differences between the averages.
