The Chieftain Press has two baling chambers (press boxes) that rotate alternately around a center column. An empty press box is filled by multiple charges beneath the tramper until there is enough to make a bale, then the full box rotates into the baling position where a large bore hydraulic cylinder compresses the cotton into a finished bale. Wires or straps are then applied and the bale is ejected. While one box is being filled, the other is compressing finished bales. The Cherokee Chieftain Press is a Down Packing press, meaning the final bale compression takes place with a hydraulic cylinder that moves downward. The press is installed at floor level. The Hydraulic Power Unit is available in several different configurations for various capacities.
