This machine works in conjunction with a tractor. When working, the output power of the tractor is transmitted to the work tool through the universal joint. The straw is cut, sucked in, and crushed by the high-speed rotating blades. Under the combined action of centrifugal force and airflow, it enters the conveying device and is sent to the centrifugal throwing machine by the conveying device. The crushed straw is lifted and blown out by the throwing drum and thrown onto the trailer transporting the straw.
