A previous study showed that the handle vibration of a walking type cultivator can be reduced by adding a mass to the handle. This study was conducted to determine the optimum magnitude and location of the mass to be added for the same cultivator. The possible locations of added mass were determined by investigating nodal points of the handle vibration by an ODS (operational deflection shapes) test at an engine frequency of 52 Hz. The optimum location was then determined as one that moved the nodal points to the hand grip of the handle bar.
