The John Deere CP690 is a self-propelled cotton picker designed for high-efficiency, non-stop harvesting. It is a significant piece of agricultural machinery known for its advanced features and ability to streamline the cotton harvesting process.

It is distinguished by its onboard round module builder, a feature that revolutionized cotton harvesting by eliminating the need for boll buggies and module builders in the field. This system allows the machine to pick cotton and simultaneously form, wrap, and eject large, round modules (bales) while continuing to harvest.
