A mobile work machine includes a frame and a ground engaging element movably supported by the frame and driven by an engine to drive movement of the mobile work machine. The mobile work machine includes a movable element movably supported by the frame to move relative to the frame and an actuator coupled to the movable element to controllably drive movement of the movable element. The mobile work machine includes a sensor that detects an operation characteristic and generates a sensor signal, indicative of the operation characteristic and a grade control system that receives the sensor signal from the sensor and determines a spillage metric, based on the sensor signal. The mobile work machine also includes a control system that generates an actuator control signal based on the spillage metric. The control signal is indicative of a commanded movement of the actuator. The control system controls the actuator to perform the commanded movement.

A bulldozer includes a blade disposed in front of a vehicle body. First and second cameras are disposed to the left and right of the vehicle body, respectively. A first optical axis of the first camera faces forward and downward. The first camera is arranged to capture a first image of a gap between a lower edge of the blade and the left crawler belt. A second optical axis of the second camera faces forward and downward. The second camera is arranged to capture a second image of a gap between a lower edge of the blade and the right crawler belt. A display is configured to display the first and second images side-by-side.

A crawler belt-type tractor includes a vehicle body, a travel device, an engine, and a fuel tank. The travel device is attached to the vehicle body. The travel device includes a crawler belt. The engine generates driving power for driving the travel device. The fuel tank is disposed in a rear portion of the vehicle body. The fuel tank stores fuel for the engine. The rear end of the fuel tank is positioned rearward of the rear end of the crawler belt.

A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller obtains first topographical data indicative of a topography of a work target before filling work. The controller obtains blade tip position data indicative of a blade tip position of the work implement during the filling work. The controller obtains second topographical data indicative of a compacted topography after the filling work. The controller determines a compression rate of the work target from the first topographical data, the blade tip position data, and the second topographical data.

One embodiment includes a grading tool structured for attachment to a work machine. The grading tool includes a frame, ground contacting wheels coupled with the frame, a comb coupled with the frame and extending from a first end of the frame, and a coupling member coupled with the frame and structured to be accessible from a second end of the frame. When the ground contacting wheels are in contact with the ground a depth of penetration of the comb into the ground surface is adjustable by changing the pitch of the grading tool.

A dozer including a cabin, the dozer includes: an engine room located in front of the cabin, where an engine is disposed; an exhaust gas after-treatment device for purifying exhaust gases emitted from the engine; a first cooling device located in front of the cabin and capable of cooling the exhaust gas after-treatment device; and a second cooling device spaced apart from the first cooling device, with the cabin midway therebetween, and capable of cooling the engine.

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.

A system and method for configuring a machine control unit of a construction machine for performing an earth-moving operation, the earth-moving operation comprising a multitude of phases that are to be performed consecutively, the method comprising, by a computing unit: receiving three-dimensional measuring data of a terrain in a surrounding of the construction machine in at least a first detection range, detecting elements of a previous phase of the earth-moving operation based on the three-dimensional measuring data, and configuring, based at least on the detected elements, the machine control unit to at least partially perform the next phase of the earth-moving operation automatically.

A ground compaction sensing system for a work machine includes a chassis, a ground-engaging mechanism coupled to the chassis, and an attachment movably coupled to the chassis. Multiple sensors are configured to generate a chassis angle signal, an attachment angle signal, an attachment spacing signal, and a location signal. The controller has a non-transitory computer readable medium with a program instruction to grade a surface. The program instructions when executed cause a processor of the controller to receive the aforementioned signals and determine an as-built grade of the surface based on an attachment reference point at a first location of the location signal; and a compaction value when a chassis reference point reaches the first location as the work machine traverses across the surface. The program instructions may then include modifying movement of the attachment based on the compaction value.

A control system for a work vehicle includes a controller. The controller decides a target profile of a work site. The controller generates a command signal to move a work implement according to the target profile. The controller acquires the load to which the work vehicle is subjected. The controller modifies the target profile according to the magnitude of the load. The controller generates a command signal to operate the work implement according to the modified target profile.
