New technologies have been incorporated into the Brazilian cotton production system, in order to verticalize the production through processing, allowing the producers or associations to add value to their production. Thus, the present study aimed to develop and evaluate processing equipment composed of mobile gin and baler press. The ginner consists of cleaner, saw cylinder, cylinder brushes, condenser and coil. The baler press is constituted of pressing sheets, hydraulic cylinders, hydraulic pump, control valve actuation, devices for filtering hydraulic oil and manometer. These devices are mounted on a trailer chassis composed of U-shaped angle iron chassis, four wheels (rim 13), shaft ends, two beams of five springs, steel sheet backing and braking system. In the evaluation and validation of the whole system by the cotton growers, this machine received the concept "very good" concerning efficiency of ginning, the bale weight, and the obtained fiber quality. The quality of fiber obtained with set ginner and baler press meet the standards of the textile industry.
