Abstract
Evaluation of the noise exposure of agricultural machine operators requires that machine operation time and intermittancy of work patterns be determined. One method of obtaining such data is by using event activity recorders. These data are available for haying machines operated at the University of Nebraska Field Laboratory, Mead during the 1963 through 1966 seasons. Approximately 60 machine operator days per season were recorded on service recorder charts for the following machines:
1. self-propelled windrowers
2. self-propelled and pull-type balers
3. self-propelled and pull-type bale wagons
In addition some motion-time study data are available for the newer loose hay stackers and large roll balers.
One seasons data, 1965, has been analyzed for a self-propelled baler to illustrate the information already available. Machine operator time and intermittancy work patterns were determined for the 35 days of baling when activity charts were obtained. Briefly, the results are summarized as follows:
