Retrofit your existing corn combine with optical yield sensing. No recalibration, no factory lock-in, no new machine. Works on John Deere, Case IH, New Holland, CLAAS, Fendt, Massey Ferguson and every other brand.
Request a DemoCorn rolls through the clean grain elevator at high mass flow, often with variable moisture from 14% to 30%+. Our optical sensor measures volumetric grain flow continuously and pairs with an inline moisture probe to give you accurate dry-yield maps in real time — without calibration loads.
Optical sensing is independent of grain density and test weight. No re-calibration when you switch hybrids, fields or moisture conditions.
Designed for class 8–11 combines moving 80+ tons/hour. Typically 95–98% accurate vs. weighbridge tickets.
Yield, moisture and productivity zones stream to your phone or tablet, then sync to the cloud automatically.
The Green Growth kit installs on the clean grain elevator of any combine that can take a corn header. Selected models below; if your machine isn't listed, ask us — installations go back to 1990s frames.

A complete retrofit kit — optical yield sensor, GPS antennas, telemetry module and all connectors. Everything you need to install on your corn combine in about 2 hours. No dealer required.
The optical sensor head mounts above the clean grain elevator paddles. A compact module in the cab handles GPS, processing, and cellular sync to the cloud.

Contact SalesYes. Older platforms like John Deere 9600/9650, Case IH 2188/2388, CLAAS Mega/Dominator and New Holland TR series accept the retrofit easily — they typically have unobstructed clean grain elevators and 12V power readily available.
Either. Many farmers run it alongside a factory CommandCenter / AFS / IntelliView display to get an independent, calibration-free dataset; others replace older or unreliable factory monitors entirely.
Yes — the Green Growth yield mapping software automatically generates productivity zones and exports ISOXML prescriptions for variable rate seeding and nitrogen application.
The kit handles all crops your combine processes — see soybean, wheat, canola/rapeseed and cereals. One kit, every crop in your rotation.
