AN373834 / PG200701 is a replacement hydraulic motor for the cotton picker head drive on John Deere 7660, 7760, CP690, and CS690 cotton pickers. These four compatible cotton pickers are commonly used in large-scale cotton fields, where some operating areas face complex conditions such as dust storms and field vibrations. This hydraulic motor integrates seamlessly with the cotton picker's hydraulic system, delivering robust load-bearing capacity. It maintains stable power output during high-speed operation or minor disruptions (e.g., minor stalk entanglement), meeting the continuous operation demands of high-yield cotton fields. It adapts to varying operational speeds of the cotton picker, ensuring excellent stability at low speeds to prevent “crawling” of the picking head that could compromise harvesting efficiency. AN373834 /PG200701 is specifically engineered for the picking head structures of these four cotton picker models. Its mounting dimensions and interface specifications perfectly match the original equipment components, eliminating the need for additional modifications to the hydraulic lines or mounting bases during replacement. This simplifies the replacement process.
