A work vehicle includes a touch-panel display, at least one first physical button, and the circuitry. The touch-panel display is to display at least one first touch button, at least one first function, and work information. The at least one function is displayed in the at least one first touch button to which the at least one first function is assigned. The work information includes a state of work which the work vehicle performs. The at least one first physical button is provided outside the touch-panel display. The at least one first function is assigned to the at least one first physical button. The circuitry is configured to change the at least one first function assigned to the at least one first touch button and the at least one first physical button in accordance with the work information.

A display device has a display screen that displays a real image captured by an image capture device mounted in a construction machine which includes working equipment, and a combined image obtained by overlapping an object image indicating a virtual viewpoint image of an object around the construction machine viewed from a virtual viewpoint of an outside of the construction machine and a construction machine image indicating a virtual viewpoint image of the construction machine viewed from the virtual viewpoint, wherein the display device displays the combined image simultaneously with the real image in a partial region of the real image displayed in the display screen.

A tile installation plow connected to a mechanical arm of a vehicle to install a tile below a ground surface, the tile installation plow including a main body to be inserted at least partially within the ground surface, a boot removably disposed on at least a portion of an inner surface of the main body to direct the tile along a portion of the main body under the ground surface, and a tile cart connected to the vehicle to hold the tile thereon.

The present Application discloses a trenching device with two operational modes, Mode 1 and mode 2. In Mode 1, the trenching lever is disengaged, the device does not trench, but only functions as a transporting unit in a forward direction with a maximum speed. In Mode 2, the trenching lever is engaged, the device starts trenching, but stops functioning as a transporting unit.

A method of using a fill mask to prevent overfill and/or spillage of a fill material from bonding to the roadway surface or staining the roadway surface during filling of a microtrench.

A hydraulic control for an attachment on a work vehicle. The attachment is mounted on the chassis of the work vehicle and movable between a first position and a second position. A hydraulic cylinder is operable to power movement of the attachment. A fluid circuit communicates with the hydraulic cylinder and is configured to carry hydraulic fluid. A fluid reservoir is in communication with the fluid circuit. Accumulators that are in communication with the fluid circuit automatically store and release hydraulic fluid in response to movement of the attachment. A valve assembly controls fluid communication between the fluid reservoir and the fluid circuit in response to movement of the attachment to its second position.

A construction machine that includes a machine frame and an articulated boom. The articulated boom is pivotably mounted to the machine frame. The construction machine is configured to be operated in a loader mode in which a first tool is mounted to the articulated boom, and in an excavator mode in which a second tool is mounted to the articulated boom. The construction machine further includes a tool storage for storing the first tool and/or the second tool. The construction machine is configured to replace one of the first tool and second tool when mounted to the articulated boom with the other one of the first tool and second tool when stored in the tool storage.

An automated backslope cutting system which, based on a survey of an area, automatically adjusts a scraper blade during the cutting of a ditch backslope. The automated backslope cutting system generally includes a scraper which is automatically adjusted by a computing device to effectuate cutting of backslopes for a ditch based on a desired cut profile. The desired cut profile may be manually entered by the operator and automatically processed by the computing device. The area is surveyed with a positioning sensor to determine an optimal desired cut profile requiring a minimum number of cuts. A proximity sensor may be provided to accommodate for rotational movement of the cutting blade as the scraper performs cuts. A control software is provided for execution by the computing device to provide functionality including the automatic adjustment of hydraulic actuators controlling movement of the cutting blade as the scraper cuts the ditch and backslopes.

A vertical cutter for a machine that can move on wheels includes, a motorized cutter rotatable with respect to its own vertical axis, elements for containing transmission elements which are integral with the cutter, supporting elements for elements for feeding and dispensing wire or cable which can rotate freely about the axis of the cutter. The cutter further includes a roller having a horizontal axis for adjusting a height of the cutter with respect to a walking surface and therefore a depth of a trench generated by it, and for covering the trench with an adjacent soil displaced by the cutter and accumulated in the vicinity of the trench, the wire or cable being accommodated and conveyed by the machine. Also included at the sides of an assembly constituted by containment elements of the transmission elements which are integral with the cutter and by supporting elements for elements for feeding and dispensing a cable, two sliding guides, which rotate freely about the axis of the cutter, for guiding and conveying an additional cable already on the ground.

A method for burying a pipeline in a bed of a body of water which includes: making a trench with a bottom surface in a bed of a body of water via a bed working vehicle advanced in an advancing direction; advancing a floating unit in the body of water; releasing a pipeline in the body of water via a tensioner and along a lay device tilted in an adjustable manner and constrained to the floating unit; guiding the pipeline to the bottom surface of the trench via a guide vehicle advanced on the bed of the body of water; and controlling the tensioner, the floating unit, the lay device, the bed working vehicle, and the guide vehicle to minimize stress along the pipeline.
