Aftermarket Yield Monitor for John Deere Combines — Easy Remote Calibration

Retrofit your John Deere — X9, S-Series, S7, T-Series, W-Series or legacy STS/WTS — with optical yield sensing. No calibration loads, no JDLink subscription, full ISOXML export to Operations Center.

Built for Every John Deere Generation

From a 1995 John Deere 9600 still earning its keep to a brand-new X9 1100, the Green Growth retrofit installs on the clean grain elevator with the same hardware. Independent of GreenStar, CommandCenter, JDLink and StarFire — works whether your subscriptions are active or not.

No JDLink Needed

Included 4G cellular link sends data to the cloud without any John Deere subscription or unlock fee.

Operations Center Ready

Native Shapefile and ISOXML exports import straight into John Deere Operations Center.

Remote Calibration

Optical sensing eliminates the calibration loads required by GreenStar / CommandCenter impact-plate systems.

What's in the Box

A complete retrofit kit — optical yield sensor, GPS antennas, telemetry module and all connectors. Two integration options: standard install on the clean grain elevator (any model), or plug-and-play CANBUS kit on modern Deere with active CAN system.

Two Install Paths for John Deere

1. Standard retrofit (any model) — optical sensor head bolts above the clean grain elevator paddles. Cab module handles GPS and 4G sync.

2. CANBUS plug-and-play (modern S/X9/S7/T) — connect through the OEM diagnostic port to use existing factory yield and moisture sensors. No drilling, no permanent modification.

  • ✅ ~2 hours, no dealer required
  • ✅ Works alongside GreenStar / CommandCenter
  • ✅ ISOXML / Shapefile to Operations Center
  • ✅ All crops: corn, soybean, wheat, canola, barley, oats

Frequently Asked Questions

Will the install void my John Deere warranty?

No. The standard retrofit mounts non-invasively above the clean grain elevator using existing service points. The CANBUS option uses the OEM diagnostic port. Neither modifies factory wiring or software.

Can I export data to Climate FieldView too?

Yes. Shapefile exports import directly into Climate FieldView, Trimble Ag and any FMIS that accepts the standard format.

Does it work on a 1990s 9600 with no GreenStar at all?

Yes — this is one of the most common installations. Legacy 9000-series machines are simpler to retrofit than modern ones because there's no factory CAN system to integrate with.

Which John Deere combines does the Green Growth retrofit fit?

Every John Deere combine model. Confirmed installations include X9 1000 and X9 1100; S-Series S660, S670, S680, S690, S760, S770, S780 and S790; S7 600, 700, 800 and 900; T-Series T550, T560, T660, T670 and T770; W-Series W540, W550, W650 and W660; legacy 9000-series 9450, 9550, 9650, 9750; 50-series 9550 STS, 9650 STS, 9750 STS; 60-series 9560 STS, 9660 STS, 9760 STS, 9860 STS; 70-series 9570 STS, 9670 STS, 9770 STS, 9870 STS; WTS series 9540, 9560, 9640, 9660, 9680; CWS 9780; CTS and CTS II.

Does it integrate with John Deere Operations Center?

Yes. Yield data exports as Shapefile and ISOXML, both natively accepted by John Deere Operations Center via the file upload flow. No JDLink subscription required.

Can I keep my factory GreenStar / CommandCenter yield monitor active alongside?

Yes. Green Growth runs as an independent system — your factory GreenStar / CommandCenter display continues to operate exactly as before. Many growers compare both readings to validate calibration loads against the Green Growth optical baseline.

What about JDLink, MyJohnDeere and StarFire GPS?

The kit includes its own GPS receiver, so it does not depend on StarFire or JDLink subscriptions. Data flows over the included 4G cellular link, independent of the combine's connectivity.
