A downdraft fan system attachable to a riding lawnmower and other lawn/farm equipment includes a rotary fan within a supporting frame that is attachable to a roll-bar component of the lawnmower so as to be positioned in a horizontal plane directly above the operator of the lawnmower. The downdraft fan system provides a constant flow of ambient air downwardly over the operator of the machine to provide protection from heat exposure, dust, and biting insects while operating the lawnmower. In one embodiment, the downdraft fan system is attachable to a pre-existing roll-bar component of the lawnmower by the use of mounting flanges and suitable attaching hardware. In alternative embodiments, the downdraft fan system is mounted in a modified supporting frame that is attachable to the frame of riding lawnmowers lacking a roll-bar component or to the roof structure of a forklift and other similar equipment.
