HARVEST TEC 880 GPS Attachment



Congratulations on purchasing a Harvest Tec Model 880 GPS attachment. The GPS harness will allow you to attach the Trimble 162 AgGPS receiver (NOT included in the 880 kit) to Harvest Tec’s 500/600 moisture monitoring system or the 565/665 preservative applicator systems. This will allow you to collect important baling information to create yield files for each individual job. The model 880 includes the harness to connect the Trimble 162 receiver to your Harvest Tec system, a USB flash drive and PIP Removable Storage Cover for a 500/565 system, and Harvest Tec’s yield mapping file converter program.


The Harvest Tec model 880GPS gathers WAAS information on the fly and sends it to the main processor. With this information, the system creates a yield mapping file that will be stored on the USB flash drive on 500/565 systems and within the processor on 600/665 systems. This yield file, after being converted by Harvest Tec’s yield mapping conversion program, can be useful to the user for present and future field management. The yield file is capable of being loaded into any type of field management software. The yield file created will indicate where each bale was tied off. If you have Harvest Tec’s Bale Identification System you will then have the ability to write that coordinate to the Tag and this will give you not only proof of what field the bale came from but also the approximate location of where the ball was made.


Installation of GPS Receiver

Locate the Trimble AgGPS 162 receiver. The GPS receiver will be mounted on top of your baler in front of the missile flag indicators or if they’re not present on a flat surface near the knotter cover/door. This location should give the GPS receiver the best available location.

Installation of GPS Harness

Connect the square plug end of the GPS harness (006-5650GPS) to the GPS receiver. Connect opposite end into one of the following:

  • Attach the GPS harness to Tagger Control (Modular Port) if the Bale Identification system is present.
  • Attach the GPS harness to the Modular Port on the Pump Controller (006-5672) if using an Automatic Preservative Applicator.
  • If the user doesn’t have a Bale Identification system or Applicator and has a Moisture only system, attach a GPS harness to the Pump Control port of the Harvest Tec processor.

Secure harness to baler with supplied cable ties, making sure wiring harness is not in any pinch points and will not come in contact with moving parts on the baler.

Harvest Tec 565 Software Updating Instructions (500/565 Systems Only)

  1. With the addition of the GPS attachment to the user’s existing 500/565 system, it will need to be updated with software.
  2. Start by downloading all of your existing Job Records off of your PIP (refer to 500, 565 or 596 manual for downloading instructions). Once any software update is done to the 500/565 system all Job Records are erased. Also, write down all important application/bale rate/tagger settings that you may want to reuse. These are returned to default once the update is complete.
  3. All software files are on the USB flash drive included in the 880 GPS Attachment kit.
    • Insert your USB flash drive into the Data Transfer port on the PIP
  4. Power the system on and the update will begin automatically. (Note: Do not power the system down or remove the USB flash during an update.)
    • The PIP and display should beep once when powered on. The display should show ‘Checking for Updates’ for approximately 1 minute.
    • After the 1-2 minutes, the display should beep once and the display should change to ‘Updating…’ Depending on how much software needs to be changed, the screen may stay on the ‘Updating…’ screen for another minute. The display will flash every 2-3 seconds. It will continue to do this until the software is updated within the Display.
    • Once the display stops flashing, the software will need to finish configuring itself. It may take another 30 seconds to a minute for the update to take effect.
      (The whole software updating process should take 2-3 minutes)
  5. Once the update process is complete, the ‘Screen Calibration’ layout will be displayed. Please recalibrate the screen to proceed to the main menu.
  6. Once at the Main Menu screen, verify that in the bottom left-hand corner it displays Version: 16050-56080. (If the correct version numbers aren’t displayed re-start the update process beginning with step 2.)
  7. Select the ‘Setup Mode’ button then find the ‘PIP Setup’ button on the lower left side. Press the ‘PIP Setup’ button to enter the ‘PIP Setup’ menu.
  8. Once in the ‘PIP Setup’ screen, three item descriptions are displayed next to three mating numerical. For Model and TSD Model press the number next to it, re-enter that default value, and press ‘Enter’ to confirm (ex: Model: re-enter 5 and press enter to confirm). For the OEM selection press the number related to your respective manufacturer and again press ‘Enter’ to confirm.

  3. For 500/565 systems, Make sure the USB flash drive is inserted into the PIP’s Data Transfer port before baling. Without the USB flash drive, a yield file will not be created. (USB flash drive provided in the 880 kits)HARVEST-TEC-880-GPS-Attachment-FIG-7


  1. Once installation and setup are complete the system is ready for baling. There is a GPS indicator icon that will appear on either of the Automatic or Manual mode screens. The GPS icon shows the user that the GPS is transmitting data to the PIP to be processed. The GPS icon, if getting a good satellite signal, will continually increase/decrease in size. While all this is going on a Yield file is being created and saved to the USB flash drive. Additionally, as you enter the Automatic/Manual mode work screens an alert message will appear above the Override key. This alert message will display “Opening USB flash” and if the PIP locates the USB flash drive successfully the alert message will disappear and the yield data will be written to the flash drive. If a different alert message is being displayed see pg. 12 for troubleshooting.HARVEST-TEC-880-GPS-Attachment-FIG-8
  2. Once baling is complete, create a New Job and the yield data file that was written to the USB flash drive will be complete and ready to be converted. See CONVERTING YIELD DATA FILE for the next step.
