The Toro 112-9752 Lawn Mower Throttle Cable controls engine speed by connecting the throttle lever to the engine’s throttle mechanism. This cable runs from the operator control to the carburetor area. It works by adjusting the position of the throttle when the lever is moved, increasing or decreasing engine speed accordingly. Smooth cable movement allows accurate speed control during operation. Replacing a worn or sticking cable restores proper throttle response and consistent engine performance while mowing.
