Abstract

An agricultural tractor (10) comprises a cooling package (22) disposed in front of an engine (20) and under a hood (14) forward of a cab (12). The cooling package (22) comprises a cooler having a major surface into which air enters. The cooling package (22) and hood (14) is inclined so that the major surface slopes upwardly in the rearward direction. The hood (14) comprises an air inlet grille (36) in the upper surface to provide an upstream air inlet for the cooling package (22), thereby significantly improving the airflow dynamics.

Claims

1. An agricultural tractor (10) comprising a cooling package (22) disposed in front of an engine (20) and under a hood (14) forward of a cab (12), the cooling package comprising a cooler (28) having a major surface, wherein the hood and the cooling package are inclined so that the major surface slopes upwardly in the rearward direction, and wherein the hood comprises an air inlet grille (36) in the upper surface to provide an upstream air inlet for the cooling package.

2. A tractor according to claim 1, wherein the cooling package further comprises a fan unit for drawing air through the cooler, the fan unit comprising a fan shroud (29) attached to the cooler and a fan (30) which rotates on an axis which is substantially perpendicular to the cooler.

3. A tractor according to claim 1, wherein the cooling package comprises at least one of a engine coolant radiator (28), an air conditioning condenser (25) and an oil cooler (27).

4. A tractor according to claim 1, wherein the major surface is inclined to the horizontal at an angle within the range of 10 to 30 degrees.

5. A tractor according to claim 4, wherein the major surface is inclined to the horizontal at an angle within the range of 15 to 25 degrees.

6. A tractor according to claim 1, wherein the engine and cooling package are mounted upon a frame member (34), which serves partly to channel the expelled air from the cooling package towards the engine.
