The working beam 5 has a left projection 9 and a right projection 10. The middle tooth 11 is attached to the working beam 5. The last tooth 12 is attached to the left projection 9. The last tooth 13 is attached to the right projection 10. The rod 7 enters the cylinder 6 and, rotating the upper and lower links 3 and 4, lowers the working beam 5 to the ground. The ripper pulls back. The tooth 11 pulls out the roots in front of the tree. Teeth 12 and 13 pull the roots along the sides of the tree. The ripper goes to a tree and the bumper 8 presses on it.
