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.

Abstract: When left and right steering levers are both operated and the operation amount of the left lever is larger than that of the right lever, a controller calculates a correction left operation amount of the left lever according to the operation amount of the right lever, and controls a left steering clutch so as to cause a vehicle body to turn toward the left in accordance with the correction left operation amount. When left and right steering levers are both operated and the operation amount of the right lever is larger than that of the left lever, the controller calculates a correction right operation amount of the right lever according to the operation amount of the left lever, and controls a right steering clutch so as to cause the vehicle body to turn toward the right in accordance with the correction right operation amount.

Abstract: A controller controls the steering device so as to cause a vehicle body to turn toward the left when a left steering lever is operated without a right steering lever being operated. The controller controls the steering device so as to cause the vehicle body to turn toward the right when the right steering lever is operated without the left steering lever being operated. The controller reduces the rotation speed of the engine when both the left steering lever and the right steering lever are operated and both the operation amount of the left steering lever and the operation amount of the right steering lever are equal to or greater than a first threshold.

Abstract: A first grille member extends from the left side of the vehicular body toward the right side. A second grille member extends from the first grille member further toward the right side. A first pivot shaft is provided at the left side of the vehicular body. The first pivot shaft extends in the top-bottom direction of the vehicular body and pivotably supports the first grille member. A second pivot shaft extends in parallel with the first pivot shaft and couples the second grille member to the first grille member so that the second grille member is pivotable with respect to the first grille member. A fan module is pivotable about a third pivot shaft provided at the left side of the vehicular body and extending in parallel with the first pivot shaft, and at least a part of the fan module is movable to an outside of the vehicular body.
