Which soybean combines is the kit compatible with?

Every combine that can take a soybean head: John Deere X9, S7, S700 series and older 50/60/70/STS; Case IH Axial-Flow 250, 240, 230 series and legacy 2588/2388/2188; New Holland CR8.90, CR9.90, CR10.90, CR11 and CX series; CLAAS Lexion, Trion, Tucano; Fendt and Massey Ferguson IDEAL; Deutz-Fahr C-series; Rostselmash Acros, Torum and Vector.

Does low soybean test weight affect accuracy?

No. Optical sensing measures volumetric grain flow and dynamically compensates for test-weight variation. Unlike impact-plate factory monitors, soybean accuracy does not degrade through wet or dry harvest windows.

Can I share fields between corn and soybean on the same kit?

Yes. One Green Growth kit handles every crop your combine processes. Field boundaries and crop type are selected in the cab app — there is nothing physical to swap between corn and soybean harvest.

How accurate is it on lodged or short soybeans?

Accuracy is driven by clean-elevator flow, not header behaviour, so lodged or short beans do not affect the sensor reading. Typical accuracy is 95–98% vs. weighbridge across full-season harvests.

Soybean Yield Monitor for Any Combine

Name: Green Growth Soybean Yield Monitor Retrofit Kit
Brand: Green Growth

Retrofit your existing combine with optical yield sensing tuned for soybean test weight and flow. No recalibration between fields, no factory lock-in, no new machine.

Built for Soybean Harvest

Soybeans have lower test weight than corn or wheat and are notoriously hard on impact-plate monitors. Our optical sensor reads volumetric flow at the clean grain elevator and dynamically compensates for test-weight variation — so you get accurate maps every pass, every field.

Test-Weight Robust

Volumetric measurement plus moisture correction = reliable bushels even when beans run light.

No Mid-Day Recalibration

Harvest from sunrise to dewfall without resetting calibration loads when moisture shifts.

Variety-Trial Ready

Switch between variety strips and your yield map zones reflect the change immediately — no manual tuning.

Frequently Asked Questions

Can I do on-farm variety trials with this?

Yes. Combine the soybean yield map with field zones in our software to compare variety strip performance directly — no spreadsheet acrobatics.

Does it handle no-till and high-residue conditions?

Yes — the sensor is mounted inside the clean grain elevator, isolated from header conditions. No-till residue, cover crops and high stubble do not affect data quality.

Will it export to Climate FieldView and John Deere Operations Center?

Yes. Yield, moisture and field boundaries export as Shapefile and ISOXML, which import into Climate FieldView, John Deere Operations Center, Trimble Ag, AgLeader SMS and any FMIS that accepts standard formats.
