Annotation: The article notes that the existing mechanical drive of the vertical spindle drums in the cotton harvester is complex, with uncovered multi-stage gear transmissions that create a strong noise, and engagements that do not occur throughout the height of the tooth. The drive of the first left drum is particularly complex, as the movement from the apparatus gearbox is transmitted through six gear engagements. Open gears quickly wear out, which disrupts the chessboard arrangement of spindles and reduces the completeness of cotton collection. It is believed that almost 80% of cotton is collected by the first pair of drums. Frequent disruptions in the chessboard arrangement of spindles of the first pair of drums, therefore, greatly affect the completeness of collection. Therefore, the authors propose to improve this drive by electrifying it. They recommend replacing the machine's distribution gearbox with a direct current generator. Electrification will make the spindle drum drive more compact. It will be possible to slightly vary the speeds of only the rear spindle drums for technological reasons.

Keywords: cotton picker, spindle drum, staggered placement of spindles, completeness of cotton picking, energy-saving drive, noise reduction.
