摘要： An ignition coil includes an ignition circuit having a first winding and a second winding, a controller in communication with the ignition circuit, and a light. The ignition circuit is configured to output an ignition timing signal. The controller is configured to establish a rule that limits an engine speed to a maximum engine speed to be provided by the ignition timing signal. The light is configured to illuminate and indicate the maximum engine speed in response to an output signal from the controller.

摘要： A multi-configurable mower deck for use with a lawnmower, the mower deck including a top surface, a front leading edge, at least one side wall extending from the top surface, and at least one partial rear wall extending from the top surface. The mower deck includes both a side-discharge opening formed on one side of the mower deck and a rear-discharge opening formed through the at least one partial rear wall. Additionally, the mower deck may include a selectively removable secondary front baffle configured to block the flow of clippings through the side-discharge opening and direct the flow of clippings toward the rear-discharge opening. The mower deck may also include at least one selectively removable rear baffle, wherein the at least one selectively removable rear baffle is configured to at least partially block the rear-discharge opening.

摘要： A hybrid light tower includes an engine, a permanent magnet generator configured to be driven by the engine, a battery pack including a plurality of lithium-ion battery cells, an extendible mast configured to move between a lowered position and a raised position, and a light assembly including a plurality of light emitting diodes. The generator is configured to produce a first DC power. The battery pack is directly electrically coupled to the generator to receive the first DC power from the generator to charge the battery pack. The light assembly is coupled to the mast and the light emitting diodes electrically coupled to the battery pack to receive a second DC power from the battery pack. The light tower does not include a battery charger connected to the battery pack.

摘要： A mower includes a pair of drive wheels, a pairs of non-drive wheels, and a mower deck. The mower deck includes a central deck housing, a first blade housing, a second blade housing, and an actuator coupled to the central deck housing and at least one of the first blade housing and the second blade housing. The first blade housing is pivotally coupled to a first side of the central deck housing so as to be angularly displaceable relative to the central deck housing, the second blade housing is pivotally coupled to a second side of the central deck housing so as to be angularly displaceable relative to the central deck housing. The actuator is configured to selectively raise and lower at least one of the first blade housing and the second blade housing relative to the central deck housing.

摘要： An internal combustion engine includes an engine block, a piston, a cylinder head, and a valve train. The engine block includes a cylinder block including a cylinder bore and a crankcase defining a crankcase chamber with a crankshaft positioned within the crankcase chamber. The piston is coupled to the crankshaft and configured to reciprocate within the cylinder bore. The cylinder head is coupled to the cylinder block. The valve train includes a camshaft, a first and second pushrod, a first and second rocker arm, an exhaust valve housed, and an intake valve. The first rocker arm, the second rocker arm, the exhaust valve, and the intake valve each include at least a layer of a low friction material. The first and second pushrod each pass through a pushrod seal to prevent fluid from reaching the rocker chamber to fluidly isolate the rocker chamber from the crankcase chamber.
