The invention provides an improvement of the twig crusher, which is mainly provided with a driving shaft and a driving device on the power system (such as an engine or a motor), and the power is transmitted to the moving mechanism of the machine body through the power transmission device (such as a belt or a chain) and the linkage device. When the twig crusher needs to move, the control mechanism and the power transmission mechanism (such as a speed change mechanism) will pass through the moving device (such as a wheel Tire or crawler) to achieve the purpose of moving the body, thus making it more convenient and easy for the debris crusher to move.本創作係提供一種殘枝粉碎機之改良，主要設於動力系統(如引擎或馬達)上設有驅動軸及驅動裝置，並藉由動力傳導裝置(如皮帶或鏈條)與連動裝置將動力傳導於機體移動機構，當殘枝粉碎機需要移動時，將由控制機構與動力傳導機構(如變速機構)藉由移動裝置(如輪胎或履帶)達到機體移動之目的，進而讓殘枝粉碎機移動時更為方便且容易。
