  • Patent number: 10843324
    Abstract: A housing assembly (26) for a working assembly (10) of an outdoor power device (20) may include a first, second, and third housing portion. The second and third housing portions may be operably coupled to the first housing portion to at least partially enclose a motor housing (60), which may comprise a body portion (62), a top endplate (64), and a bottom endplate (66) to house an electric motor for driving the working assembly (10). The first, second, and third housing portions may combine to define a first opening and a second opening (132, 134) such that two opposing sides of the body portion (62) are exposed in respective ones of the first and second openings (132, 134). In addition, or alternatively, a gap (130) may separate the housing assembly (26) from the entirety of the top endplate (64), the entirety of the body portion (62), and a substantial majority of the bottom endplate (66).
