FIELD: construction.
SUBSTANCE: digging machine includes a ripper with at least one working tooth mounted on a lever, hinged to the frame of the machine, and the hydraulic cylinder of its lifting and lowering hingedly connected to the base machine and to the ripper lever. The longitudinal axis of the hydraulic cylinder for lever lifting and lowering is located in the plane passing through the end part of the ripper's tooth. In this case, the longitudinal axis of the hydraulic cylinder for lever lifting and lowering also passes through the hinged joint of the hydraulic cylinder and the base machine.
EFFECT: increase in reliability of the hydraulic cylinders by eliminating the effect of eccentric loads within the entire range of ripping depth.
