ABSTRACT:
Ventilating apparatus for farm equipment used in the fumigation of crop fields including the provision of a ducted blower unit disposed directly above the head of a fumigation equipment operator so as to cause a continual downward flow of air over the operator's body when the equipment is in use. The apparatus includes a shroud for housing an electrically or hydraulically driven fan which collects air from the space above the tractor and forces it downward in a flow enveloping the operator. In alternative embodiments, various filtration devices may be utilized as well as flow directing deflector assemblies, heat exchangers and misting applicators.
