| Summary: | The grass cutting machine is a widely used agricultural machine for cutting grass by the
roadside and in other areas in Malaysia. Grass cutting involves the use of a motorized cutter
spinning at high speeds. A number of recent studies have shown that workers were affected
by whole body vibration in agriculture field. Many researchers had published studies on
whole body vibration (WBV) in agriculture field but none was done for Malaysian grass
cutter recently. The objective of the study was to determine the subjective correlation
variable on whole body vibration among grass cutter workers using WBV questionnaire and
to investigate whole body vibration exposure action and vibration dose values at back rest of
working operator. The study covered 55 workers that were maintaining landscape and grass
cutter at Selangor district. The details with the various aspects such as height, weight, model
of machine, various areas and experience regarding of work involved. Field measurements of
WBV were measured according to the international standard IS0 263 1-1 : 1 on the grass cutter
workers. WBV was measured in 3 axes with a tri-axial seat pan accelerometer and recorded
to a Larson Davis Vibration Monitor (HVM 100). The workers whom exposed to these
machines have a greater chance of having lower back pain or other kind of pain in their body
due to the vibration exposed to their whole body every day. This particular study will help in
finding ways to minimise the health issues of the workers. |
