Abstract: A tractor cabin having struts, a top framework, an air conditioner mounted on the top framework, and a ceiling assembly covering an entire ceiling area of the cabin. In order to optimize air conditioned flows, the ceiling assembly includes outlet vents in a front region thereof for delivering defrosting air flows, outlet vents in lateral sides thereof for delivering air flows for the driver, an inside air intake vent in a rear portion thereof inside the cabin, and an outside air intake vent rearwardly and outwardly of the cabin. The ceiling assembly further includes an overhead console box having an air conditioning control unit and other elements. The console box is disposed such that its lower end is on or above a straight line extending from the driver's eye level to the top edge of a windshield to provide the driver with an unobstructed forward view.
