This replacement governor gear is a certified genuine OEM part for a lawn tractor or mower engine. The governor is responsible for regulating the throttle. The interaction of the governor spring and governor gear works to position the throttle in such a way that it only allows a set amount of fuel into the carburetor. With less fuel in the carburetor, the engine will run slower. In this case, a slower engine means slower blade rotations. Like any gear, the governor gear has teeth the spin against another gear. Over time, the constant gnashing of gear teeth will cause the gears to wear down and possibly slip out of alignment. Once a gear is out of alignment, it will either stop working completely or degrade more quickly and should be replaced as soon as possible. Replacing the governor gear will require disassembling the engine cover and should be done in accordance with the owner's manual and manufacturer's instructions. This replacement governor gear is a high-quality part sourced from its original manufacturer. It is compatible with engines made by Briggs & Stratton and Toro. This shipment includes a governor gear and the brackets required for assembly.
