OEM-EVIDENCED CLASS DOSSIER

Harvester and Agricultural Machine Technical Dossier: Crop Flow, Automation and Diagnostics

A class dossier linking verified combine applications with crop flow, engine/drive, electronic automation and measurement logic.

Verified model applications

Cards open only existing model pages that pass the bilingual OEM-primary publication gate.

Case IH lists Harvest Command automation and dual Pro 1200 displays as manufacturer system components on the Axial-Flow 260 product page.

New Holland describes Twin Rotor technology as a defining architecture of the CR combine range.

The Massey Ferguson international product site lists MF IDEAL as a current combine product family.

Split the harvester into header/feed, threshing/separation, cleaning, grain handling/unloading, engine/drive and automation layers.
Electronic automation coordinates sensors and actuators; an automation code alone does not prove a mechanical failure.
Crop condition and engine/rotor load jointly affect performance, so field-condition data is part of diagnosis.

Capacity loss: engine derate/load → feeder load → rotor/threshing → cleaning → grain handling.
Grain loss/quality: crop condition → setting command → actual mechanical position/speed → sensor feedback.
Telemetry/terminal warning: connectivity/network → local ECU data → actual machine function; remote data does not replace physical measurement.

Record commanded/actual behavior under the same crop, moisture, load and machine settings.
Do not derive clearance, speed, pressure or hydraulic thresholds from product pages; use sub-model/serial-specific service information.
After repair, verify both quality/capacity outcome and warning recurrence under the same field condition.
