Abstract: An engine hood includes an outer shell with vertical front, right and left sides and a planar top that covers an engine and its radiator. An inner panel is fixed to the inner surface of the hood underneath an opening in the top. This inner panel directs air passing through the opening in the top forward to in front of the radiator. The inner panel is fixed to the hood at its rear and side edges, and abuts the top of the radiator with it front edge. This prevents heated air flow from behind the radiator over the top of the radiator and into the radiator air inlet and the combustion air inlet.

Abstract: A work vehicle having a novel hood coupling apparatus is disclosed. The work vehicle includes a frame provided with a compartment and a hood. The hood is coupled to the frame by at least one hinge and at least one latch. The latch includes a stationary portion associated with the frame and a movable portion associated with the hood, and the hinge includes a first portion associated with the frame and a second portion associated with the hood. The latch is configured for the stationary portion to engage the movable portion in a particular location when the hood is closed, and the second portion of the hinge is configured to assume an approximate position with respect to the first portion of the hinge, and thereby to the frame, upon engagement of the latch, the latch thereby aligning the hood and the second portion of the hinge to the frame when engaged. The work vehicle may also include a hood biasing device and a hood positioner for controlling the amount of opening of the hood.
