Yield Monitor for Case IH Axial-Flow Combines

Retrofit your Case IH — Axial-Flow 250, 240, 230, 88 or 20 series, or legacy 2188 / 2388 / 2588 / 1688 — with optical yield sensing. No AFS calibration loads, ISOXML and Shapefile to AFS Connect.

Built for Every Axial-Flow Generation

From an iconic 1995 Case IH 1688 still on the back forty to a brand-new Axial-Flow 9250, the Green Growth retrofit installs on the clean grain elevator with the same kit. Independent of AFS Pro, AFS Connect and Trimble RTK subscriptions.

No AFS Subscription

Included 4G cellular sends data to the cloud without AFS Connect or any Case IH subscription.

AFS / FieldView Ready

Native Shapefile and ISOXML imports straight into AFS Connect, Climate FieldView and any FMIS.

Calibration-Free

Optical sensing eliminates the calibration loads required by the factory AFS impact-plate system.

What's in the Box

A complete retrofit kit — optical yield sensor, GPS antennas, telemetry module and connectors. Standard install on the clean grain elevator (any Axial-Flow generation), or plug-and-play CANBUS on modern Axial-Flow 230 / 240 / 250 / 20 / 88 with active AFS CAN.

Two Install Paths for Case IH

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 Axial-Flow with AFS) — connect through the AFS diagnostic port to use existing factory sensors. No drilling, no permanent modification.

  • ✅ ~2 hours, no dealer required
  • ✅ Works alongside AFS Pro / AFS Connect
  • ✅ ISOXML / Shapefile to AFS Connect, FieldView
  • ✅ All crops: corn, soybean, wheat, canola, barley, oats

Frequently Asked Questions

Does it work on a 1995 Case IH 1688 with no factory monitor?

Yes — this is one of our most common installations. The 1660/1680/1688 family has unobstructed clean grain elevators and 12V power, making them easy to retrofit.

Will it interfere with AFS RowGuide or AccuTurn?

No. The retrofit runs independently — AFS RowGuide, AccuTurn and any other AFS features continue to operate as normal.

Can I aggregate yield from Case IH and John Deere in a contractor fleet?

Yes — mixed-fleet yield data aggregates yield maps from any combination of brands.
