A ripper assembly is disclosed. The ripper assembly may include a ripper cross-member defining at least a first ripper shank pocket. The ripper cross member may include a front wall, a rear wall, a first side wall and a second side wall. The front wall may connect to the rear wall, to define a perimeter of the at least first ripper shank pocket, the front wall, the rear wall, the first side wall, and the second side wall, and to also define a longitudinal axis and a free end disposed along the longitudinal axis adjacent the perimeter of the at least first ripper shank pocket. At least one of the front wall, the rear wall, the first side wall and the second side wall may define a retention boss aperture and a retention mechanism pocket in communication with the retention boss aperture.

A vibration ripper having a link structure with an improved vibration isolating function is characterized by including: a first vibroisolating body installed across the vibration body from a left lower portion of the vibration body; and a link device for connecting the outer body and the first vibroisolating body in order to absorb vibrations, wherein the link device is provided with a pair of connection members which are spaced apart from and parallel to each other, a coupling hole for coupling the first vibroisolating body is formed in the left side of the connection members, and a second vibroisolating body coupled to the outer body is integrally installed on the right side of the connection members.

A robotic vehicle for moving above ground while fabricating a subsurface polymer layer to protect an underground structure is provided. The robotic vehicle includes: a body; a rotational member that contacts the ground and moves the body over the ground; a ripper assembly having a proximal end that moves with the body, and a distal end that moves underground at a fabrication depth in response to the movement of the proximal end while fabricating the polymer layer; a ground penetrating radar (GPR) that locates and measures a depth of the underground structure below the ground; and a computerized control system that controls the rotational member, the distal end of the ripper assembly, and the GPR to move the body over the located underground structure while tracking the location of the underground structure and fabricating the polymer layer at the fabrication depth and above the measured depth of the underground structure.

An accessory mounting system for a work vehicle includes a first mount extending from a lateral side of a body of the work vehicle, in which the first mount is configured to couple to a first end of a rotatable component to rotatably couple the rotatable component to the body of the work vehicle. Further, the accessory mounting system for includes a cover assembly having a cover, in which the cover assembly is coupled to the lateral side of the body of the work vehicle, and at least a portion of the cover is positioned laterally outward from the first mount such that the first end of the rotatable component is disposed between the lateral side of the body of the work vehicle and the portion of the cover while the first end of the rotatable component is coupled to the first mount.

A work machine comprises a body, a ripper apparatus that is disposed behind the body, and an imaging device that is mounted to the body and images the ripper apparatus. The ripper apparatus includes a shank, a ripping tip that is attached to an end of the shank, a beam that supports the shank, and a ripper arm that interconnects the body and the beam. The imaging device images the ripper apparatus sideways and captures an image in a range including at least a portion of the shank, at least a portion of the beam, and at least a portion of the ripper arm.

A ripper shank as the impact and wear resistant component is made of a steel of a specific component composition which has a hardness of HRC 53 or more and HRC 57 or less. The steel includes a matrix including a martensite phase and a residual austenite phase, and first nonmetallic particles dispersed in the matrix and including at least one species selected from the group consisting of MnS, TiCN, and NbCN. The steel does not include a M23C6 carbide.

The invention is directed to a method and apparatus of forming two or more waving rip lines across a sloping surface, wherein the rip lines are formed at substantially right angles to the downward direction of the sloping surface and have a plurality of peaks and troughs. The troughs form catchment areas for water and the peaks separate the troughs limiting the amount of water stored in the catchment areas. Each of the rip lines can be substantially parallel with each other or offset relative to an adjacent rip line. The plurality of waving rip lines contribute to the stability of the landform, long term conservation and maintenance of the landform, and thereby encourage establishment and growth of vegetation in the remediation process.
