Abstract
A cotton harvester row unit having an in-line drum arrangement and a door chamber cross section which remains generally constant from the rear structural post so that the suction door can be moved closer to the row centerline to narrow the overall width of the unit. The unit is sufficiently narrow that cotton in row spacings of less than 30 inches can be harvested. The new suction door location allows the cotton from the rear doffer to enter the door more directly. The row unit picker drums include picker bars with 14 or 16 spindles per bar to shorten the height and weight of the unit and permit use of shorter stalk lifters so that unit length is also reduced. A two-row tractor mounted picker utilizes the narrow row units mounted on a rail type of support system at the rear of a tractor. The units are laterally adjustable on rails for accommodating different row spacings and patterns, including 60 centimeter row spacings and 60-30 centimeter skip row spacings. The tractor rockshaft control valve, connected through a height control valve to lift cylinders, provides unit lift and automatic height control.
