This paper explains a method of testing electronic equipment for vibrational problems in a quick and easy way. Resonant frequencies are generated in a test bed and with the use of mathematic equations developed in the paper, potential problems can be assesed and problems corrected.

Little concern has been given to environmental considerations in the past. Times are changing and there must be a realization of the effects being made by farm machinery on the soil, air and water supply. This paper discusses these realities and proposes that much could be gained by incorporating automation into farm equipment.

Electronics are very sensitive to vibration and it is mandatory that the design engineer be familiar with the environment in which they will be used. This paper describes the vibrational environment of a tractor. A full scale tractor cab was outfitted with sensors and vibrated at various frequencies. The results are supported by theoretical calculations.
