A tractor equipped with an environmental enclosure for pesticide application (John Deere Model 6410) was evaluated after it had been in use for about one year. Optical particle counters were used to measure the particle number concentration inside and outside of the cab during a discing operation. The evaluation was conducted with old filters which had about 700 hours of service and with new replacement filters. Changing the filters did not greatly affect the exposure reduction offered by the filters. The exposure reduction and static pressure in the cab were acceptable in terms of American Society of Agricultural Engineers Standard S525. However, the dust concentration in the cab increased as the testing was conducted. The reason for this increase and its significance are unclear.
