    Abstract: A blower includes a frame, a surface engaging wheel attached to the frame and a power source attached to the frame. An impeller housing is also attached to the frame, and the impeller housing defines an intake opening. The impeller housing surrounds an impeller that is rotatably connected to the power source. An exhaust chute is attached to the impeller housing. A selectively closeable aperture structure is attached to the intake opening. In further examples, the selectively closeable aperture is a pair of rotatable plates both including radial slots or an iris blade assembly. In other examples, the exhaust chute is rotatable or the impeller housing is rotatable.

    Abstract: A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

    Abstract: Disclosed is an alternator overvoltage protection circuit having a TRIAC and a MOSFET. The TRIAC is electrically connected to the MOSFET and the TRIAC is electrically connected to a magneto. The TRIAC is configured to ground the magneto when triggered by the MOSFET. The MOSFET is electrically connected to an alternator and configured to conduct when the alternator operates in an overvoltage condition. Also disclosed is a method of alternator overvoltage protection for a piece of outdoor power equipment, the method including providing a TRIAC and an alternator rotated by an engine having a magneto, wherein the alternator outputs a voltage when rotated by the engine. The method further includes configuring the TRIAC to ground the magneto when the alternator operates in an overvoltage condition, thereby disabling the magneto, which stops the rotation of the engine and stops the alternator from outputting voltage.
