Abstract

The purpose of this research is to development of rice leaf cutter for reduction of vibration by using Finite element method for strength analysis.  The pre-analysis showed that total Deformation of 0.13762 mm which was relatively very little. When comparing chain drive with belt drive and lawn mowers for an effective cutting area of 400 m2 and motor speed of 350 rpm horizontal vibration from the chain drive was 4.75 mm and 5.61 mm from belt drive. Additionally, it was found that vibration decreased by approximately 15.33 % when the chain was used instead of the belt and reduced by 7.44 % when compared with lawn mowers. Vertical vibration at 350 rpm was 4.32 mm for a chain drive and 6.86 mm for belt drive. Vibration value decreased by 37.03 % when chain drive was used instead of belt and reduced by 19.40 % compared with lawn mowers. This reduces work time by 30.90 minute per Rai. And can reduce the cost of farming by 640 baht per Rai.
