Frequently Asked Questions

Product Questions

What components are included in the UHarvest Data Management System?

Standard Components:

  • Junction Box for scale load cell cables, mounted on the grain cart
  • ECU (Electronic Control Unit) mounted on the grain cart
  • Processor located in the tractor cab
  • Accu-Save includes a Drivetrain RPM Sensor that automatically saves each load
  • Complete Wiring to connect system components (ISO cable, processor cable)

Optional Components:

  • Moisture Sensor mounted on the grain cart clean-out door
  • Accu-Load includes a Hydraulic Valve Block & Cabling to unload a pre-programmed weight
  • ISOBUS Cable Adapter for NON-ISOBUS tractors

Grain carts NOT equipped with scale load cells:

  • For any Brent, Killbros, Parker or Unverferth grain carts, scale load cells can be purchased in conjunction with the UHarvest system from your dealer.
  • For all other grain cart brands, appropriate load cells will need to be purchased separately.

How will the above components mount to my grain cart?

If your grain cart is currently equipped with scale load cells, you will need to plug each of the scale load cell cables into the provided Junction Box, which mounts on the grain cart. A cable will run from the Junction Box into the ECU, which also mounts on the grain cart. An ISOBUS cable will run from the ECU to the front of the grain cart and plug into the ISOBUS port on the tractor. An optional ISOBUS cable is available for NON-ISOBUS tractors. This cable will run from inside the tractor cab to the rear of the tractor.
