Everything you need to get started with precision yield mapping – in one package.

We’re working on removing barriers to participation in precision agriculture. With the FarmTRX system, farmers can outfit the  equipment they already own for modern yield mapping, regardless of the factory capability of the combine. Our Internet-of-Things (IoT) approach means farmers can install the hardware once and benefit from “over-the-air“ performance upgrades for years.

The Harvest Bundle includes all hardware and software components necessary to get started. Installation of the Yield Monitor and Moisture Sensor can be completed on any combine in a matter of hours, with account registration and setup of fields done via the FarmTRX Web App.

Purchase of every Yield Monitor includes a full year’s access to cleaned, filtered and corrected yield maps generated automatically by the Web App.

Here’s what’s in the box:

Data Logger and Optical Sensors


Data Logger

The black box is the brains of the Yield Monitor operation. It mounts in the cab of the combine and features an on-board processor, 32 GB of storage and an internal GPS chip/antenna. Your smartphone or tablet pairs with the Yield Monitor using Bluetooth® connectivity. Calibration of the Yield Monitor is completed in the FarmTRX Mobile App using volume, weight, or volume and weight. Monitor the live and average yield and moisture readings from the cab on your smartphone or tablet.

Don’t have the time to calibrate before harvesting, or worried about potential miscalibration affecting your final yield map? Don’t be. Farmers are able to get accurate precision yield maps after the fact with post-harvest calibration done through the Web App, so you can be confident when you go to harvest that relative yield is always being recorded. More on that here…


Optical Sensors


Two right-angle, ruggedized optical sensors install on either side of the clean grain elevator and use a light beam to record yield on each passing paddle. Removable hardened lenses protect the sensors from external wear and are easily replaced when required.

QuickConnect Sensor Mounts


Our patented QuickConnect technology provides an efficient click-into-place installation and secures to the elevator using a 3M industrial level adhesive.  This model allows farmers to cut down optical sensor installation time dramatically.

Drill Guide Kit

We supply a complete Drill Guide Kit with every Yield Monitor. The kit includes a drill guide, 1/8” (3 mm) pilot hole bit, 3/4” (18 mm) step–drill bit and a drill extension allowing for straight-through drilling from the outside of the elevator. The Drill Guide Kit lets installers avoid having to get in behind the elevator to drill.

External GPS Antenna


The external multi-constellation (GPS/GLONASS/Galileo) antenna provides greater positional accuracy to the Yield Monitor and simplifies locating the data logger in the cab. It mounts on the roof of the cab on the centerline of the combine.

Wiring Harnesses

The kit comes equipped with all necessary wiring harnesses to supply power to the Yield Monitor and Moisture Sensor. Included you will find the 8 ft. (2.4 m) Sensor Interconnect Wiring Harness and the 20 ft (9 m) Primary Wiring Harness.

Moisture Sensor


The Moisture Sensor installs on the lower door of the clean grain elevator and adds grain moisture sensing capability to the Yield Monitor. With calibration, the sensor provides live and average moisture values (wet and dry) that can be monitored with the FarmTRX Mobile App. A precision moisture map is generated as an output by the Web App.
