What It Is

A throttle switch/handle on a power weeder is the control device mounted on the handlebar that lets the operator regulate the engine speed (throttle) while using the machine. It’s typically a lever or grip with a cable that connects to the carburetor or engine governor, allowing you to increase or decrease engine RPM smoothly without letting go of the handle.
