Systems and methods for trenchless placement of an underground protective network of intertwined cables for protecting buried assets from accidental damage are disclosed. The system includes an apparatus for towing behind a vehicle and laying a plurality of continuous cables directly underground and interweaving the cables to form a cable network. The apparatus includes a plurality of soil rippers mounted at respective radial positions to a rotating carrier. The rotating carrier rotates about an axis that is at least partially normal to the ground surface. The rippers plow through the ground in the direction of vehicle travel and include a cable-feeding guide for directly and continuously feeding cable out underground during operation. In operation, the combined movement of the soil rippers from rotating the carrier and movement in the direction of travel serves to intertwine the cables deposited by respective rippers forming the protective network of intertwined cables.

A control method is performed in a motor grader, the motor grader including a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle. The control method includes detecting a load applied to the blade and revolving, when the detected load is larger in value than a predetermined reference value, the swing circle in such a direction that the blade angle is smaller than the blade angle at the time of detection of that value.

A scraper having a frame with a first removable sidewall removably coupled to the frame, a second removable sidewall removably coupled to the frame, a rear bucket pivotally coupled to the frame and having a dump position and a carry position, the rear bucket comprising a first rear sidewall positioned on a first side of the rear bucket and a second rear sidewall positioned on a second side of the rear bucket. Wherein, the first removable sidewall is positioned adjacent to the first rear sidewall and the second removable sidewall is positioned adjacent to the second rear sidewall. Further wherein, as the rear bucket transitions between the carry position and the dump position, the first and second removable sidewalls move relative to the surface of the corresponding first and second rear sidewalls.

A control system and method for a work machine includes an input control, an input interface, and a controller. The input control is moveable in at least a first direction to provide control of the work machine. The input interface is configured to receive a control selection input. The controller is configured to set a control action in response to receiving the control selection input from the input interface, and the work machine is controlled as defined by the control action upon the input control moving in the first direction to a position along the first direction.

A land plane that may be moved over an agricultural field to smooth any irregularities in the surface of the field is pulled by a tow vehicle and has a blade assembly in a general diamond shape. The general diamond shape may be between 30 and 35 feet wide and 35 and 40 feet long. Thus, the land plane may have a sufficient length for drag and earth moving capability to economically and properly level a field, and a sufficient width to cover a substantially large area in single pass over the field. Further, the land plane may have foldable wing sections that enable the land plane to be transported over a typical state or county road or highway.

A grading machine may include a machine body, a grading blade, at least one grading blade sensor configured to sense a position and orientation of the grading blade, a drawbar connecting the grading blade to the machine body, at least one drawbar sensor configured to sense a position and orientation of the drawbar, a user interface, and a control system. The control system may be configured to receive an input from the user interface and position and orient the grading blade and the drawbar to one of a plurality of predetermined ditching positions based on the input.

A controller controls a first drive source and a second drive source based on a moving speed of a motor grader measured by a speed sensor and a turning angular velocity of the motor grader measured by an IMU, to thereby independently control a rotation speed of each of a right front wheel and a left front wheel.

A cutting tool assembly is disclosed. The cutting tool assembly may have an adapter board, which may have at least one bore, extending from a proximal end to a distal end. The assembly may also have a cutting tool, having an elongated tool body. At least a portion of the tool body may be disposed within the bore. The tool body may have an annular channel on the tool body adjacent the distal end of the bore. The assembly may have a spring clip, having a generally hollow cylindrical sleeve, circumscribing at least a portion of the tool body within the bore. The spring clip may also have a flange attached to and extending radially outward from the sleeve. The spring clip may also have a circumferential rib extending radially inward from the sleeve. The circumferential rib may be configured to engage with the annular channel within the bore.

An implement attachment device for tractors allowing for easy and quick attachment of implements and tools to a tractor bucket along with correspondingly easy and quick detachment of such implements and tools, wherein such device may itself may be readily connected or disconnected to the bucket and while connected may be easily switched from a bottom use-ready position to a top stowed position in relation to the tractor bucket.

A reconfigurable material moving attachment for a vehicle includes a blade having a blade working face directed toward a front of the blade; and a coupling mechanism for reversibly mounting the blade to the vehicle. The coupling mechanism includes a first coupling portion fixed to the blade and a second coupling portion attachable to the vehicle. The second coupling portion is releasably interconnectable with the first coupling portion in: (i) a forward pushing configuration, in which the blade working face is directed away from the vehicle for pushing of the blade during forward operation of the vehicle to collect and push material in a material collection space adjacent the blade working face, and (ii) a back-dragging configuration, in which the blade working face is directed toward the vehicle for pulling of the blade during reverse operation of the vehicle to collect and back drag material in the material collection space.
