    Abstract: A radiator grill is mounted on a work vehicle and includes a frame and a plate member. The plate member is supported by the frame and having a plurality of through-holes aligned in a first direction and a second direction orthogonal to the first direction. Each of the through-holes has a pair of circular parts aligned in the first direction, and an interconnecting part having a width in the second direction that is smaller than diameters of the circular parts, the interconnecting part interconnecting the circular parts. The through-holes are disposed alternately so that one of the circular parts of one of two adjacent ones of the through-holes adjacent to each other in the second direction is aligned with the interconnecting part of the other of the two adjacent ones of the through-holes in the second direction.

    Abstract: A bulldozer includes an engine, first and second exhaust treatment apparatuses arranged above the engine, a relay connection pipe connecting the first and second apparatuses, and an engine hood covering upper parts of the first and second apparatuses. The relay connection pipe has a cylindrical shaped main section, a first section connecting the main section and the first apparatus, and a second section connecting the main section and the second apparatus. The lower end of the main section is positioned above upper ends of the first and second apparatuses. The upper surface of the hood has a convex section protruding above the relay connection pipe and a base section formed integrally with the convex section below the convex section. At least a portion of a line segment extending along the upper edge of the main section overlaps an upper surface part of the convex section in a bulldozer top view.
