摘要： A work vehicle includes a traveling vehicle body and a hood provided at a front portion of the vehicle body for covering an engine room. The hood includes a front face having a plurality of first air vent holes and right and left side faces each having a plurality of second air vent holes. A radiator is mounted inside the hood, ambient air being drawn in through the first and second air vent holes toward the radiator. A vent hole area ratio of each side face of the hood determined by the second air vent holes is set smaller than a vent hole area ratio of the front face of the hood determined by the first air vent holes.

摘要： 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.

摘要： A hydraulic circuit for a working vehicle comprising a first pump, a second pump, a first actuator, a second actuator, and a selector valve having a plurality of control positions. The selector valve is switchable between a first position for connecting the first pump to the first actuator and the second pump to the second actuator, and a second position for connecting the first pump and the second pump to the second actuator. This circuit includes a first relief valve disposed between the selector valve and the first pump, and a second relief valve disposed between the selector valve and the second pump. The first relief valve is set to a higher relief pressure than the second relief valve.
