Abstract

Hand tractors are among the major agricultural machinery used by Filipino farmers. Prolonged exposure to vibration from hand tractor may lead to the risk of Hand-Arm Vibration Syndrome (HAVS). This study compares the effectiveness of vibration dampeners available in the market when operating a diesel- and gasoline-powered hand tractor. The experiment was done in a stationary position based on the standards set by IS/ISO 5349:2001. The baseline measurements at 2100, 2700, and 3300 rpm are as follows: 6.60, 7.12 and 10.50 m/s2 for diesel-powered hand tractor, and 6.81, 4.65 and 11.04 m/s2 for gasoline-powered hand tractor, respectively. Combination of handle grips and engine mounts were tested to determine the optimal reduction of transmitted hand-arm vibration. The combination of BMX handle grip with mount model F5A has the highest percent reduction to the vibration by 35.23% (5.13 m/s2) when using diesel-powered hand tractor. Mountain bike handle grip with mount model F5A yielded the highest reduction by 52.29% (3.24 m/s2) when using gasoline-powered hand tractor.
