摘要: The mower includes a frame which is supported for movement upon a plurality of ground engaging wheels and upon which are supported a motor generator set, an internal combustion motor and a plurality of reel lawn mowers. The motor generator set provides electrical energy for electric motors that drive the reel type lawn mowers. A housing encloses the internal combustion motor and motor generator set and utilizes a combination of passive noise abatement and active noise abatement to reduce noise generated within the interior of the housing. The passive noise abatement is provided at plurality of locations around the motor generator set within the housing.
