    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.

    Abstract: A suspension for a tracked utility vehicle is provided. The trailing link suspension for the tracked utility vehicle has at least two trailing links Each of said trailing links has a shock and a walking beam. The first end of the trailing link is pivotably connected to the tracked utility vehicle chassis. The second end of said trailing link is pivotably connected to the walking beam. The first end of the shock is pivotably connected to the chassis and the second end is pivotably connected to the trailing link The walking beam has a plurality of axle mounted bogey wheels for engaging one or both of the track of said tracked utility vehicle or the track lug or guide. The shocks are independently adjustable to permit more of the tracked utility vehicle's weight to be supported at the suspension midpoint.

    Abstract: The parking brake system for a lap bar controlled lawn maintenance vehicle includes at least an actuation assembly and a stop assembly. The actuation assembly includes a push arm and a rotatable pedal arm, and the push arm is attached to a lap bar and is rotatable between and engaged position and a disengaged position. Rotation of the push arm from the disengaged position to the engaged position causes rotation of the pedal arm, and such rotation of the pedal arm causes the stop assembly to prevent the axle for the rear wheel that is controlled by the corresponding lap bar from rotating.
