Hand operated farm machinery produces higher amounts of vibrations, which can cause Musculoskeletal disorders like white finger syndrome and blanching of fingers. Long term exposure to this vibration leads to fatigue and discomfort that causes lower performance efficiency of the worker. Weeding is an important operation in cultivation of row crops. Large farms require weeding machinery for proper and quick removal of weeds. Otherwise, there will be a huge loss in production that raised due to the competition between weeds and the main crop for nutrients. In this study, two different types of power weeders were taken for vibration measurement. These two are different in constructional material, weight and source of power. The vibrations transmitted to hand are higher in amar power weeder during intercultural operations i.e. 17.55 ms-2 at a speed of 2800 rpm. In both the power weeders, HTV increased as the speed is increased. In BCS power weeder, there are some arrangements to dampen the vibrations. It produced only 4.85 ms-2 and 5.20 ms-2 at the speeds of 1800 rpm and 2700 rpm during intercultural operations respectively. Therefore, BCS power weeder is more comfortable to the operator.
