Abstract: A work vehicle includes a vehicle main body, a work implement, an engine, an idle reduction execution portion, and a position determination portion. The work implement is provided in the vehicle main body and includes a boom provided to be drivable in a vertical direction, an arm provided to be drivable with respect to the boom, and a bucket attached to a tip end of the arm. The idle reduction execution portion can stop the engine in an idling state. The position determination portion determines whether or not the bucket may interfere with the vehicle main body, based on a position state of rest of the work implement. When the position determination portion determines that the bucket may interfere with the vehicle main body, the idle reduction execution portion does not stop the engine, and when it is determined otherwise, the idle reduction execution portion stops the engine.

Abstract: A display system for a machine includes multiple imaging devices configured to capture image data of an environment around the machine. The display system includes a position sensor configured to generate signals indicative of position of an operator seat. The display system further includes a display screen in communication with the imaging device and the position sensor. The display screen receives the image data from the multiple imaging devices. The display screen displays an image on the display screen based on the image data. The display screen receives the signals indicative of the position of the operator seat. Further, the display screen adjusts the image being displayed on the display screen based on the position of the operator seat.
