Abstract: Provided is a display system, which makes it easy for an operator to accurately grasp a traveling situation of a work vehicle. A front camera captures an excavating blade and topography in front of a crawler dozer. A rear camera captures a fuel tank and a ripper apparatus, and a topography behind the crawler dozer. A display image displayed on a monitor is generated by arranging a front image captured by the front camera and a rear image captured by the rear camera so that the excavating blade in the front image may face the fuel tank in the rear image.

Abstract: 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 overlaps a left crawler belt as seen in a plan view of the bulldozer and 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 overlaps a right crawler belt as seen in a plan view of the bulldozer and 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.

Abstract: A bulldozer has a protective structure. The protective structure includes a left pillar portion, a right pillar portion, and a beam portion. The left pillar portion is disposed to the left of a cab and extends in the up-down direction. The right pillar portion is disposed to the right of the cab and extends in the up-down direction. The beam portion is disposed above the cab and couples the left pillar portion and the right pillar portion. A first camera is attached to the left pillar portion and is disposed so that a first optical axis faces forward and downward. A second camera is attached to the right pillar portion and is disposed so that a second optical axis faces forward and downward.

Abstract: A work machine includes: a partition member provided with an intake port and an exhaust port and forming an engine room; an engine disposed in the engine room; a cooling fan disposed on an intake port side of the engine in the engine room; an exhaust pipe discharging exhaust gas from the engine; and an exhaust duct disposed in the engine room and having an inflow port into which air from the cooling fan flows, and an outflow port. At least a portion of the exhaust duct is disposed above the engine and has a facing surface facing the engine and a through-hole provided in the facing surface. At least a portion of the exhaust pipe is disposed in the through-hole. A gap is formed between an outer surface of the exhaust pipe and an inner surface of the through-hole.

Abstract: An amount of information of data of a captured image displayed on a display unit is increased. A display control unit sets a plurality of divided display sections for a display unit. The display control unit sets a first camera group and a second camera group including one or more of a plurality of cameras. The first camera group captures an image of a work performed with a blade. The second camera group captures an image of a work performed with a ripper. The display control unit displays data of captured images output from cameras included in one of the first and second camera groups in a corresponding plurality of divided display sections.

Abstract: A controller determines that a signal from an operating device represents either a normal operation to manually control a blade or a trigger operation to automatically control the blade. The controller moves the blade so that the angle of the blade is changed in accordance with the operation of the operating device when the signal from the operating device is determined as representing a normal operation. The controller moves the blade until the angle of the blade reaches a predetermined target angle when the signal from the operating device is determined as representing the trigger operation while the bulldozer is traveling.
