It is an important part of the micro-tiller and can control the opening and closing of the clutch of the micro-tiller, thereby controlling the forward and backward movement of the micro-tiller. The clutch handle is usually composed of a rod body, a handle, a connecting rod and a spring. When the handle is pushed forward, the rod body moves the connecting rod forward to open the clutch and the micro-tiller starts to move forward. When the handle is pulled backward, the rod body moves the connecting rod backward to close the clutch and the micro-tiller stops running or reverses. The advantage of the clutch handle is that it is simple and convenient to operate and can quickly control the micro-tiller.
