If you have a combine with 12V and a clean grain elevator, you can begin yield mapping with FarmTRX. The system includes all software and hardware components necessary to bring precision yield monitoring to any farmer, arriving to your door in just one box. Over-the-air software updates allow farmers to buy and install once and take advantage of on-going operating and mapping advancements for years.  

To get the most out of your Yield Monitor we suggest following these 9 steps before harvesting. While following this checklist ensures accurate live readings in the cab, remember that FarmTRX will still produce precision yield maps with a post-harvest calibration by weight or volume in the Web App. If you’re tight on time come harvest, have a few different operators in rotation, or made a calibration error, you’ll still get precision yield maps by using the elevator ticket results and calibrating through the FarmTRX Web App. Ensure there is power to the Yield Monitor and go confidently.

If you’re new to farming with FarmTRX, follow these 9 steps to get setup for harvest: 

  1. Register your FarmTRX Web App account 
  2. Add and edit equipment, headers and crops
  3. Create or import field boundaries 
  4. Download the FarmTRX Mobile App
  5. Install the FarmTRX Yield Monitor
  6. Connect to the Yield Monitor and confirm power
  7. Perform a sensor calibration/tare
  8. Perform crop calibration once per crop type per year 
  9. Upload your yield data to the Web App (whenever you like!) 
1) Register your FarmTRX Web App account 

Create your FarmTRX Web App account by visiting if you’re farming in the Americas, and if you are farming in Europe, the Middle East or Africa.

2) Add and edit equipment, headers and crops

Begin the account setup procedure in the Web App. Enter account details such as contact information and your preferred units of measurement. Select the combine model, headers and crop types you will be using at harvest. 

3) Create or import field boundaries

The FarmTRX Web App is the location where your yield data will be uploaded, automatically sorted and corrected to produce precision yield maps.  Whenever you decide to upload your yield data, whether daily, weekly or all at once at the end of harvest, the data will need a place to populate – this is your field boundaries.  

Users can create or import field boundaries after harvest, but if you want to see your data processed sooner, create field boundaries and add headers and crop types beforehand. Your boundaries must be set in the Web App for any uploaded data to be processed into yield maps as part of FarmTRX’s commitment to your data integrity.  

Create field boundaries by pressing the plus icon in the left side bar of the Web App. Add a field name and draw the field boundaries using the available drawing tools. If you already have field boundaries, import them to the Web App as .shp files. Boundaries can be customized at any time and we suggest reviewing them yearly to ensure they are as accurate as possible and no harvested area is being missed. 

The Web App automatically detects the crop type and assigns it to the field once the yield data is uploaded.

4) Download the FarmTRX Mobile App 

Through the FarmTRX Harvest App farmers edit the header width and perform sensor and crop calibration from the cab. With proper calibration, accurate live and average yield and moisture readings will display on your mobile phone or tablet while harvesting. 

The mobile app should be updated on the Apple App or Google Play store before harvest to ensure the latest version is in use. Updates to the firmware functionality of the Yield Monitor and Moisture Sensor happen over-the-air, meaning no additional update costs.  

 5) Install the FarmTRX Yield Monitor

The Yield Monitor is a single package solution, arriving with all components required to start yield mapping. Patent-pending QuickConnect optical sensors allow an easier and faster installation of the sensors onto the clean grain elevator. A supplied drill guide kit lets the installer drill parallel sensor holes on both sides of the elevator from just the front side, avoiding having to get in behind the elevator to drill. 

6) Connect to the Yield Monitor and confirm power

Your smartphone or tablet uses Bluetooth connectivity to connect to the Yield Monitor. Make sure your Bluetooth is toggled on in your mobile device settings in order to connect. You will be prompted to update to the latest firmware (if required) as part of the most recent FarmTRX Mobile App update.

Confirm that the Yield Monitor is installed correctly by turning over the machine while the key is in the on position. The Yield Monitor status LED will show a solid red light when powered on and flash green when ready for operation.

7) Perform a sensor calibration/tare 

To calibrate the optical sensors, engage your separator clutch and run the combine at full throttle while stationary, with no grain running through the elevator. Navigate to the Device Calibration page on the FarmTRX Mobile App to run a sensor calibration. Hit the “Start” button once the elevator is running at full throttle. The Yield Monitor will record the elevator and determine the width of the empty paddles in order to optimize recordings.

8) Perform crop calibration 

To get accurate readings in the cab, calibrate in the field by volume, by weight or by a combination of both. We recommend calibrating once per crop type per year.

Navigate to the main menu of the FarmTRX Mobile App and select Crop Calibration to begin calibrating.  Press “Start Calibration” and hit the checkmark icon. After a hopper-full has been harvested, enter the measured weight and/or volume along with measured moisture if using the FarmTRX Moisture Sensor. If you left your smartphone or tablet behind, or didn’t have time to calibrate before harvesting, you can still calibrate halfway through or after harvest by inputting the total harvested volume or weight for each field into the FarmTRX Web App.

9) Enter your web credentials to upload your yield data (whenever you like!)

Yield data can be uploaded to the Web App for processing at any time using available WiFi or mobile data. Precision yield and moisture maps will generate in the App automatically within minutes of data upload, and are available to export as ESRI shapefile, AgLeader, Google Earth and Climate Fieldview files. All users have the ability to export their raw yield data at any time, while access to the complete suite of precision yield and moisture maps is available with yearly subscription based on acreage. Subscription to the FarmTRX Web App is free for the first harvest year.

If you’re just getting started with FarmTRX, we suggest uploading yield data once per harvest day to familiarize yourself with the yield map outputs and double-check that calibration is accurate.  If you would rather upload less frequently in bigger data chunks, you can do that too!
