Operators are able to monitor harvest through robust map layers that improve the in-cab experience.
Harvest Mobile monitors and documents the following data attributes:
Ground speed – measurement of distance over time to show how fast the combine is moving at a specific area in the field. This is a new harvest map layer to be displayed in the cab.
- Moisture – measurement of 0-100 percent that shows the moisture content of the crop for a specific area in the field. This is also able to be displayed and captured in the GreenStar™ 3 (GS3) 2630 Display and 4600 CommandCenter™ display harvest documentation data.
Dry yield – measurement in mass per area after taking into consideration the removal of moisture to the standard payable moisture. This is a new harvest map layer to be displayed in the cab.
- Wet yield – measurement in mass per area for a specific area in the field. This is also able to be displayed and captured in the GS3 2630 and 4600 CommandCenter harvest documentation data.
Each data attribute in Harvest Mobile can be shown as a dashboard and map layer. The dashboards are numerical values that represent the current real-time value provided by the machine. The map layers are each documented at one time per second, displayed on top of an aerial image (dependent upon the cellular connection to the iPad® tablet) and have color legends that can easily be edited.
Expanded visualization through Dual Map Display
Making decisions about next year's crop based upon an evaluation of this year's crop performance during harvest is becoming more valuable. Harvest Mobile provides the operator with a visual representation from which to draw conclusions about what worked well and what did not, all while harvesting. Operators can now visually see two live harvest maps in Harvest Mobile for a single field. The application enables the operator to choose a client, farm, field, and then two map layers that are available on the app. The definitions provided below further explain Live vs. Historical:
- Live = Current client, farm, field being harvested. These include ground speed, moisture, dry yield and wet yield map layers
- Historical = Variety maps retrieved from the John Deere Operations Center
In order to see two live maps, the app must be connected to the machine via the WDS; however, it does not require cellular connectivity. The dual map display experience is best visualized with a cellular connection in order to provide a GPS position (if outside of the combine) and aerial imagery for use as a background.
In base equipment
Harvest Mobile hardware is factory installed on all model year 2016 and newer S-Series combines, making it easy to get started with Harvest Mobile.
NOTE: Harvest Mobile uses Wi-Fi to stream data between the combine and the iPad. While John Deere has verified the system to work in typical field operations, John Deere cannot guarantee that system performance will not be impacted due to signal interference from non-Harvest Mobile transmitters. Since the 2.4 GHz ISM band is a license-free, shared spectrum, it is possible that other systems may consume bandwidth and degrade the system performance.

Variety map retrieval
In order to evaluate a variety's performance real-time while harvesting, Harvest Mobile operators will need to retrieve their fields' variety maps from the John Deere Operations Center prior to harvest. This can be done over Wi-Fi (not the WDS or MTG Wi-Fi connection to the combine) or cellular connection. It is recommended to load the variety maps prior to harvesting via Wi-Fi to reduce cell plan costs as well as achieve optimal download speeds. Once variety maps are loaded in Harvest Mobile, operators can access those maps at any time via Dual Map Display or Field Review.
Wireless flow of data where it is needed
Flow of harvest data
Harvest Mobile utilizes the wireless capabilities of the wireless data server (WDS) or 4600 CommandCenter and MTG and the iPad to send the harvest data from the combine to the operator inside the combine cab. The harvest data is stored on both the iPad and the WDS or 4600 CommandCenter. Harvest Mobile also sends data from the iPad to the WDS to the combine for functionality such as machine setting adjustments with Interactive Combine Adjustment (ICA).
Harvest Mobile utilizes the cellular capabilities of the iPad to sync data to John Deere Operations Center. Data can also be sent to the Operations Center via Wi-Fi when the iPad is not connected to the WDS or 4600 CommandCenter and MTG. While Harvest Mobile data will be sent to Operations Center, currently there is no ability to view the data in Operations Center. See John Deere Operations Center for additional information.
