Abstract: A bulldozer includes a cab and an engine hood. The cab has a foremost surface, and left and right front surfaces. The engine hood has an upper surface, left and right side surfaces, and flat first, second and third inclined surfaces. The first and second inclined surfaces contact the rear side of the upper surface and rear sides of the left and right side surfaces, and are inclined more obliquely to the right rear and left rear than the left and right side surfaces, respectively. The first, second and third inclined surfaces are inclined to face downward to the rear. The third inclined surface contacts the first and second inclined surfaces, and the upper surface. A window attached to the foremost surface is arranged in a vertical direction above first and second sides closest to the foremost surface out of sides constituting the first and second inclined surfaces, respectively.

Abstract: A bulldozer includes a cab, a fuel tank arranged to a rear of the cab, and first and second engaging members. The cab includes a driver seat and an air-conditioning cooling module projecting rearward from an upper end portion of the cab. The first and second engaging members are provided on the fuel tank, with each having an engaging part to engage onto a suspension member. The engaging part of the first engaging member is positioned on a first lateral side of a first straight line connecting a first lateral side end of the air-conditioning cooling module and a first lateral side end of the fuel tank. The engaging part of the second engaging member is positioned on a second lateral side of a second straight line connecting a second lateral side end of the air-conditioning cooling module, and a second lateral side end of the fuel tank.

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.
