A mounting frame is disclosed for supporting a speed control device and a drive source in operative relationship. The frame is preferably of U-shape configuration having spaced apart, parallel legs which define a section in a first plane for mounting receipt of one of said drive source and said speed control device, and a second section for cantilever support from said first section when installed, said second section of said legs being located in a different plane than said first section of said legs and being adapted for mounting receipt of the other of said drive source and said speed control device. The second cantilevered section of said legs is not supported from said one of said drive source and said speed control device, and the mounting structure precludes reaching of the resonant frequency of the drive source support structure during the operating range of same or significant transfer of vibration from one of said drive source and said speed control device to the other.
