Abstract: A lift cylinder is attached to a center part of a vehicle body in a vehicle width direction. The lift cylinder causes a work implement to move up and down. A supporting member is attached to the center part of the vehicle body in the vehicle width direction and extends upward from the vehicle body. An imaging device is supported by the supporting member and captures images of a region in front of the vehicle body. A penetrating part is formed in the supporting member. The lift cylinder is disposed through the penetrating part.

Abstract: A control system for a work vehicle includes an acceleration detection device and a controller. The acceleration detection device detects an acceleration of the work vehicle. The controller determines whether the acceleration is greater than a first threshold and reduces the a vehicle speed when the acceleration continues to be equal to or greater than the first threshold over a predetermined first determination time period.

Abstract: A first capturing image unit mounted on a vehicle body captures an image of surroundings of a work vehicle. A second capturing image unit is disposed above the work implement and captures an image of an area in front of the work implement. A first image generation unit generates, from the image captured by the first capturing image unit, a surroundings composite image, which depicts the surroundings of the work vehicle in a bird's-eye view and is synthesized with a vehicle model depicting the work vehicle. A second image generation unit generates, from the image captured by the second image capturing unit, a work implement composite image, which depicts the area in front of the work implement and is synthesized with the vehicle model and the surroundings composite image. A display unit displays a display image including the vehicle model, the surroundings composite image, and the work implement composite image.

Abstract: A track link which is a tracked undercarriage component is made of a steel having a specific component composition, and includes a high hardness portion having a hardness of HRC 57 or more and HRC 60 or less, and a low hardness portion. The high hardness portion includes a first matrix including a martensite phase and a residual austenite phase, and first nonmetallic particles dispersed in the first matrix and including at least one species selected from the group consisting of MnS, TiCN, and NbCN, and it does not include a M23C6 carbide. The low hardness portion includes a second matrix including a martensite phase, and second nonmetallic particles dispersed in the second matrix and including at least one species selected from the group consisting of MnS, TiCN, and NbCN, and it does not include a M23C6 carbide.
