FarmTRX Yield Monitor – Install Guide.
Before installing, make sure to read the Quick Start Guide: www.FarmTRX.com/documentation
This guide will walk through the installation of a FarmTRX Yield Monitor. It is shown being
installed on a New Holland CR9060, but should be typical of all New Holland CR series & Case
AFX combines, and is similar to the install process for most other combines.
System Overview:
1. FarmTRX Yield Monitor: The "brains" of the operation. This device features an on-board
computer that connects to the optical yield sensors, 16gb of on-board storage (enough
to store years of harvesting data), a GPS antenna, and Bluetooth connectivity for pairing
with a smartphone or tablet. It mounts in the cab and needs to be wired into switched
12V power.
1.1 GPS Antenna (optional): This is required when it is not possible to mount the Yield
Monitor along the center-line of the cab, or if the harvester cab has a metal roof.
2. Mass-Flow Optical Sensors: Two sensors will be installed on either side of the clean
grain elevator. A light beam is sent between the two sensors, allowing for the
measurement of the volume of grain on each paddle. These sensors will be wired
directly to the Yield Monitor through the supplied harnesses.

Install Yield Monitor Components used in this step: Yield Monitor 20 ft. Primary Cable The Yield Monitor installs in the cab of your combine. It needs to be powered by 12V switched power. Since it contains a GPS antenna, it should be mounted as close to the centerline of your combine as possible (alternatively, the Yield Monitor cab be mounted elsewhere and an external GPS antenna can be connected and mounted along the centerline) Install Yield Monitor: 1. Remove any headliner panels or lights needed to access 12V switched power and a space to install the yield monitor. 2. Locate 12V switched power lines to tap into. 3. Use the supplied T-Splice Connectors to connect to +12V & Ground. Use pliers to snap the T-Splice Connectors onto the wires. Be sure to use the correct size connector, and ensure the connector “snaps” shut. Use the Blue T-Splice connector for 18-14 AWG wire Use the Blue T-Splice connector for 22-18 AWG wire. 4. With the T-Splice connectors attached to 12V switched power, attach the Red & Black spade connectors from the leads on the Primary Cable to +12V & Ground, respectively. 5. Connect the 15 Pin connector of the Primary Cable to the Yield Monitor & tighten screws. a. To test the power: turn on the combine, then use your smartphone to search/scan for Bluetooth devices. A device called “YM:___” should appear. 6. Install YM on center-line of combine. Remove any panels or lights necessary to access a spot along the centerline. Mount the Yield Monitor with the label facing skyways and use double sided tape to mount it in place. A potential place to mount the the Yield Monitor for the installation pictured here would be in front of the cab light on the center-line. a. If power access and cable routing is too difficult, or your combine has a metal roof, then see below 7. Using an external GPS: screwing an external GPS on to the threaded SMA connector on the Yield Monitor will turn off the internal GPS, and instead use the attached antenna.
- Page 4 Showing possible install location of yield monitor in middle of headliner a. Alternative: Install the YM anywhere inside cab and align GPS antenna along centerline of combine (shown below). Showing Yield Monitor installed in aft right hand corner of cab (where switched power is conveniently accessible) In this install the GPS antenna was installed forward of the cab light in the headliner. This places the GPS antenna along the center-line of the harvester. Cable Routing: 8. Once the Yield Monitor is mounted, route the Primary Cable through your cab/headliner and out to underneath your cab. You will need to route it towards the clean grain elevator.
- Page 5 Showing routing of Primary Cable along inside of door post. Ignition switch assembly removed for access. 9. Once the Primary Cable has been routed outside of your cab, use the supplied zip ties to route it over to the clean grain elevator. Leave a few feet of cable loose by the clean grain elevator to attach to the interconnect cable.
- Page 6 2. Install Optical Sensors Components used in this step: Optical Sensors Mounting Brackets Sensor interconnect cable In this step you will be mounting the optical yield sensors on your clean grain elevator. The location of the mounting point is found in a table below. Preparing Sensors & Brackets: 1. Mount optical sensors in mounting brackets. Use supplied nuts, washers, and plastic spacers. Mounting Order: Nut, washer, Lightly hand tighten jam nuts to make face of sensor flush bracket, washer, nut, spacer. with the mounting face of the bracket (shown above)
- Page 7 2. Screw the plastic spacer on to the sensor until it is flush with the face of the sensor, then screw the spacer slightly more to reveal only one thread of the sensor. This will help the sensor sit at the correct depth in the clean grain elevator. 3. One sensor has a set of LED lights recessed in the barrel. These will help you test the system, so ensure they are pointed away from the hinge of the bracket. (shown above)
- Page 8 Mounting Sensors & Brackets: Next, you will need to measure and mark where to measure, mark, and drill holes for the sensors on the clean grain elevator. They mount in the inside & outside face of the elevator, towards the back of the combine (where filled paddles of grain pass by). The table below shows the measurements for common combines: Combine Model Distance X (in) Height Y (in) Case IH 1660 1.75 41.5 1680 1.75 75.5 2X88 1.75 75.5 7088 1.75 75.5 7120, 8120 1.5 New Holland CR9XX, CR9XXX 1.75 TR9X 1.5 John Deere 9500 2.25 96X0 2.25 9X50 2.25 9X60 2.25 Diagram of Optical 9X70 2.25 Sensor Placement Gleaner...
- Page 9 1. Using measurements from the table above, measure & mark the height (Y). Measure from the center of the bearing, to height (Y), and mark. We recommend using masking tape to make marking the height easier. Use a framing square to trace the height (y) across the masking tape on the clean grain elevator. It is very important to install the optical sensors directly opposite each other, so take care with marking the mounting holes. Shown: line drawn on tape to mark exact height of sensors from bottom bearing. 2. With the height (Y) marked across the clean grain elevator, measure & mark the distance (X). Shown: marked sensor hole location (x) from of the back of the clean grain elevator. 3. With height (Y) and distance (X) marked, use a center punch to mark the location for drilling the sensor mounting pilot holes.
- Page 10 4. At the marked location – drill a pilot hole using a 5/32” drill bit. 5. Using the pilot hole as a starting point - use a step drill to drill a ¾” hole.
- Page 11 Using the step-drill-bit to drill ¾” hole Showing: step-drill bit used. 6. Use a file to remove sharp burs from the drilled hole. 7. Mount the sensor brackets: Slide head of sensor into the new ¾” hole. Loosen jam nuts on sensor and slide the bracket until the 4-hole pattern is located in the middle of the clean grain elevator. Press the head of the sensor into the ¾” hole, hold the bracket at 90 degrees to the vertical edge of the elevator, and mark the 4-hole pattern of the bracket for drilling.
- Page 12 8. Once bracket & sensor are aligned, drill one hole with a 5/32” bit. 9. Choose correct sensor to install: Before pop-riveting the sensor on, make sure to select the sensor with the LED light in the barrel. Having this LED light visible will help to test the system. (Shown below) 10. Next, install one pop rivet to hold the bracket, then drill the remaining holes.
- Page 13 Use a pop rivets to mount the bracket to the 1 drilled hole. 11. With 1 pop rivet installed, drill the remaining 3 holes and install their pop rivets. 12. Repeat the process on the inside face of the clean grain elevator. Take care to ensure the ¾” hole is drilled directly across from the other (using the same x,y measurements). Repeat the process on the inside face of the clean grain elevator. Take care to ensure the ¾” hole is drilled directly across from the other (using the same x,y measurements). If access to the back of the clean grain elevator is restricted, you can create a sheet metal drilling template for the sensor pilot hole (for the harvester’s specific X dimension) and use an angled drill to drill the pilot and sensor holes.
- Page 14 13. Once both brackets and sensors are mounted, use the included XL zip tie to hold the brackets together as shown: 14. With the brackets and sensors mounted, attach the connectors of the sensor cables to the connectors on the Interconnect Cable. 15. Connect the Interconnect Cable to the Primary Cable. Zip tie excess cable in a bundle away from moving parts. Cables connected & zip tied out of the way. NOTE: There will be an open connector on the interconnect cable. This connector will allow you to use attach other components in the future. Zip tie this connector out of the way.
- Page 15 Testing Optical Yield Sensors: Once the optical sensors are installed and they are connected to the yield monitor, the system can be tested in the following way: 1. Power on the harvester. This should power on the yield monitor wired to switched 12V power. 2. With a smartphone, look for a Bluetooth device to appear with the name: “YM:____”. If this appears, then the yield monitor is powered on. 3. Next test the optical sensors. With the harvester powered on (the engine does not need to be on for this), go to the clean grain elevator, remove the clean out panel and advance the paddles by hand. When the empty paddles pass by the optical sensors, the sensor with the LED (ideally installed on the outer face of the elevator) should blink. If this happens, then the optical sensors are powered on correctly and in alignment. Your yield monitor should now be fully installed.
