Stop Guessing, Start Knowing: The FJD AYM Yield Monitoring Solution
For generations, the end of harvest brought one question: “How did the field do?” The answer was often a total truck weight and a gut feeling. This post explores how the FJD AYM Yield Monitoring Solution transforms combines into data-gathering tools, answering the crucial question of not just how much was harvested, but exactly where it came from .

The FJD AYM Yield Monitoring Pain of the Unknown
Farming decisions made on a field-wide average can be costly. Treating a field’s lowest-yielding dirt the same as its highest-yielding dirt means wasted inputs in poor areas and missed potential in good ones . This is where precision agriculture comes in. It moves farming from managing by the field to managing by the square foot . The FJD AYM system is designed to capture the precise data needed to make this shift a reality.
The Science Behind the FJD AYM Yield Monitoring
The AYM system works by merging three critical data streams at the same time: Grain Flow, Moisture Content, and Position & Area .
- The “Eyes”: Optical Sensors: The system uses modern optical sensors mounted in the clean grain elevator, the channel carrying grain to the tank. Instead of older, less reliable “impact plate” technology, these sensors use light beams to accurately measure the volume of grain passing by in real-time .
- The “Brain”: ECU & Moisture Sensor: The system’s Electronic Control Unit (ECU) is the calculator. It combines the grain flow data with precise moisture readings from a high-precision sensor. This is vital because grain is sold based on a standardized dry weight. The moisture sensor, with an accuracy of ±0.5%, ensures the system converts “wet” flow into an accurate, saleable “dry weight” yield figure .
- The “Navigator”: GNSS Receiver: A dedicated GNSS receiver tracks the combine’s position with ±2.5cm accuracy using RTK. By merging this data with the header width, the system knows the exact area being harvested at every moment. This allows it to generate accurate yield maps showing exactly which parts of the field are performing .

FJD AYM Yield Monitoring A Universal Solution for Your “Old Iron”
A common myth is that you need a brand-new combine to get smart data. The FJD AYM is designed as a universal retrofit kit. It can be installed on almost any combine with a clean grain elevator, often in as little as two hours by two people . This accessibility makes advanced yield monitoring a reality for farmers operating older, proven workhorses like a John Deere 9600 .
The FJD AYM Yield Monitoring Power of Real-Time Data
The information from the AYM system is displayed on a terminal inside the cab, giving the operator an instant, real-time view of the harvest.
Real-Time Moisture Monitoring
Farmers can view live moisture data instantly. This allows them to:
- Avoid dockage penalties by selling grain at the optimal moisture level.
- Adjust the harvest schedule on the fly, moving to drier zones when a field is too wet.
- Make immediate storage decisions on whether grain needs drying .
Live Yield Mapping
The system automatically creates a yield map during harvest. The operator can see which areas of the field are outperforming others without waiting for the whole field to be done . This data is crucial for post-season analysis, helping to compare the performance of different seed varieties, fertilization methods, or even the effectiveness of different farming practices .

The Synergy with Autosteering
The AYM solution is often paired with the FJD AT2 Auto Steer System. This combination creates a powerful, unified system .
- Reduced Operator Fatigue: Harvest days are long. Autosteering handles the steering, allowing the operator to focus on the yield monitor and header .
- Improved Data Accuracy: By maintaining perfectly straight lines and avoiding overlaps, the system ensures the yield monitor is calculating acreage with the highest possible accuracy. This eliminates errors in bushels-per-acre data caused by partial passes .
Analysis: Turning Data into Dollars
The FJD AYM system is designed to be a profit generator. It allows farmers to make data-driven decisions that directly impact their bottom line.
- Fair Land Rent Negotiation: Yield maps provide concrete evidence to landlords about drainage issues or poor soil quality affecting production .
- Variable Rate Planning: The maps help create “prescription maps” for the next season, guiding seeding and fertilization rates to optimize inputs in low-yield zones and maximize potential in high-yield areas .
- Fleet Management and Logistics: Data synced to the FieldFusion cloud platform allows for centralized monitoring of all machines, helping to track harvest progress and optimize logistics in real-time .
For Canadian farmers operating classic equipment like the John Deere 9600, the FJD AT2 and FarmTRX integration provide a powerful and affordable path to precision agriculture . It confirms that the future of farming lies not in replacing every machine, but in intelligently upgrading proven workhorses with the best in modern guidance and monitoring technology FJD AYM Yield Monitoring
