In a Spanish‑language demo at the Expo Agro Guanajuato 2025, the speaker promotes the Ray Controller (also called GreenStar Recontroller) for agricultural spreaders. The pitch emphasizes that the device works with non‑John Deere spreaders, enables variable‑rate application that can cut fertilizer or chemical use by up to 20 %, and consolidates all controls onto a single cabin screen, eliminating cable clutter. It automates valve opening and adjusts dosage in real‑time based on prescription maps, allowing the operator to monitor the system remotely. The speaker frames these features as simplifying operation, reducing passes, increasing productivity, and delivering measurable profitability gains.
