Ripper is a passive traction working device, which is generally installed on the rear frame of self-propelled machinery such as graders, bulldozers or tractors.
The ripper is mainly composed of the main body of the ripper, the oil cylinder, and the hydraulic pipeline. When working, under the traction of the main engine and the action of the hydraulic oil cylinder, the ripper teeth are gradually pressed down to a certain depth of soil under the ground, and then move forward with the main engine to loosen the soil. At the end of the work, the ripper teeth pass through the oil cylinder. Lift off the ground.
