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.
