<p>Cotton harvester structure including centrally located, transversely mounted engine, rear mounted water and fuel tanks, and transversely centered conveyor fan having an upper, forwardly extending outlet located just below the level of the cab floor for improved weight distribution, air hose routing and air flow. The fan rotates about a transversely extending axis parallel to the engine crankshaft axis. The crankshaft and fan are connected by a belt and sheave assembly having an electric clutch mounted on a shaft assembly and located outside of the frame. The shaft assembly provides fan support, separates the fan inlet from the clutch, reduces lubrication requirements, and enhances accessibility. Two variable displacement hydraulic pumps connected to the row unit drive and ground drive motors, respectively, are driven in tandem from the crankshaft at one side of the engine and are adjustable to vary the ratio of row unit speed to harvester ground speed over a range of ratios, including a ratio that synchronizes ground speed and row unit speed. A side mounted radiator with a rotary cleaner is located on the opposite side of the frame between the front and rear wheels. The water and fuel tanks are nested closely to each other and extend rearwardly of the rear wheels.</p> |
