Vibration transmitted to the hand by backpack blowers

Backpack machines such as grasscutter and blower produce a vibration that is transmitted to the operator’s body and hand. Prolonged exposure to vibration can cause injuries known as Hand-Arm Vibration Syndrome. One of the machines used widely in the agriculture sector is the blower. The objective of...
