An engine cooling structure comprises a hood enclosing an engine and defining air inlets and an air outlet, a radiator disposed rearwardly of the engine, a cooling fan disposed forwardly of the engine for drawing cooling air and exhausting the cooling air forwardly. A closed cooling duct system extending from the air inlets to the air outlet is formed by the hood, a guide plate for guiding all incoming air flows to the radiator, and shielding plates extending from a forward body frame and sealing an engine room from below. The cooling air flows through the radiator, past the engine and through the cooling fan.

Engine cooling structure for agricultural tractor

A transmission system for a tractor comprising a double clutch for transmitting engine output to an inner shaft consitituting part of a propelling line and to a tubular outer shaft constituting part of a power takeoff line. The double clutch includes a first and second flywheels, and the second flywheel defines a boss for relatively rotatable supporting a forward end of the outer shaft therein. The transmission system further comprises a propelling line change speed mechanism including a reversing gear and a reversing shaft for supporting the reversing gear. A rotational resistance applying device is provided on the reversing shaft for applying a rotational resistance to the propelling line by frictional engagement with the reversing gear.
