Abstract: A noise reduction shroud is provided for use with utility engines that have attached blower housings. The shroud comprises a one-piece shell positioned above and around the blower housing located on the engine to define a space between the shroud and the engine, wherein the shell is adapted such that air entering the blower housing must first flow from a bottom side of the engine up through the space between the shroud and the engine. In another embodiment, the invention is a lawnmower or other lawn and garden equipment, comprising such a noise reduction shroud.
