Abstract: In an attempt to meet the food demand by the ever increasing human population, the use of machines in the performance of agricultural operations is increasingly being emphasized. Two of the most common operations for which machines are used on the farm are ploughing and harrowing. Tractor operators who perform these functions are known to spend long period of time working with the machines and various implements which generate substantial noise. Exposure to excessive noise could be harmful to human health if not regulated. The focus of this study was to investigate the level of noise to which tractor operators are exposed during ploughing and harrowing operations using MF260 and MF 265 tractors the noise level generated varied from 88.6 to 89.4dBA for ploughing and 86.5 to 88.4 dBA for harrowing. These levels are more than the recommended level of 85dB which indicate that the operators are under threat from noise and precautionary measures are desirable. A good maintenance culture especially the lubrication of parts to reduce noise, the use of ear protector such as ear muffs and plugs and cabins on tractors are recommended as ways by which the noise exposure could be minimized.
