An engine cooling system for field machinery such as tractors equipped with a lawnmower. A cooling system is arranged with a radiator placed in a slanting position in the upper rear part of engine within engine room and with the lower end of the radiator placed on the engine side. A cooling fan is so mounted that the cooling air induced by the radiator cooling fan passes through upward from under the radiator. The cooling fan is preferably placed downstream in the cooling air flow of the radiator, that means, above the radiator. Further it is desirable that a cooling air passage is so arranged that the cooling air which has passed through the radiator may blow out of air outlet through the vicinity of the engine, and that the outgoing air flow is so directed that hay blown up by field machinery\s travels and operations be kept away from cooling air inlet, for instance, being directed forward ahead of the engine.

A cooling system for an engine in a compartment forming part of a farm machine exposed to small plant particles, comprising a cooling radiator in an upper portion of said compartment and rearwardly of said engine, said radiator being disposed angularly from the horizontal with the lower end thereof slanting toward said engine; a cooling fan disposed above said radiator to draw cool air from beneath and upwardly through said radiator; a cooling air inlet disposed in the upper rear portion of said compartment; and an exhaust air outlet disposed near the front end of said compartment to direct the exhaust air ahead of said machine, whereby to blow such plant particles ahead of the machine and minimize the amount thereof reaching said cooling air inlet.
