Abstract
Backpack mist blower is one of the major machinery used by Filipino farmers. Since backpack mist blower is motorized, it transmits vibration to the operator. This study was done to assess the vibration transmitted by the TAJIMA 3-in-1 Knapsack-Type Sprayer Sower. Three male operators with normal BMI were selected. Vibration transmitted was measured and evaluated using ISO 2631-1:1997. The results showed that vibration acceleration is highest along the x-axis, followed by the z and y axis. The dominant frequency of vibration accelerations were observed at the engine speed. Factorial DOE showed that location and engine speed significantly affect vibration acceleration. Operators felt 3.42 m/s^s vibration acceleration at 2620 rpm, 7.99 m/s^2 at 3410 rpm, and 3.38 m/s^2 at 5590 rpm. With these levels of vibration, operators should limit their time working with the backpack mist blower at 2620 rpm up to 10.26 minutes. At 5590 rpm, the working time is up to 10.50 minutes, the maximum time is 55.57 minutes. The best engine setting to use is either 2620 rpm or 5590 rpm because they have almost the same level of vibration acceleration. With these engine speeds, the operator may use the backpack mist blower continuously within 10 minutes or 55 minutes.
