Libra Cart

Powerfully simple harvest management system

Simplify harvest data collection

The Libra Cart system connects to your load cells and wirelessly communicates with the Libra Harvest app through Bluetooth®.

It automatically detects and records every unload from your grain cart without additional sensors, providing accurate, real-time harvest data on your tablet or smartphone — no need to press any buttons or write anything down.

Reduce cab clutter

Compatible with both iOS and Android, Libra Cart is app-based and uses a mobile device instead of a traditional grain cart scale indicator, clearing up valuable space in the cab.

Access New Features

Update new app features and firmware right from your mobile device

Track inventory and get
valuable insights

Track the whole harvest process. Know exactly how much came off each field, where it went, and how much is left in your bins, so you are never guessing or overselling.

Conduct field trials by comparing yields so that you can have confidence in knowing what products will get you the most out of your land.

Track Fields, Trucks, Destinations

View totals and weight transactions for every field, truck, and destination (bins, bags, elevators, contracts)

Manage Inventory

Transfer amounts from one destination to another to track what has been moved or sold

Calibrate the combine’s yield monitor

Get more with the cloud

View live weights and individually tare from other devices within Bluetooth® range to keep an eye on things or easily calibrate the yield monitor in the combine.

View and edit all totals and weight transactions from remote devices in the truck, combine, or anywhere with Cloud Pro.

Connect to External Scoreboard Displays with Serial Link

View live grain cart weights from the Libra app on standard external scoreboard displays for enhanced functionality and visibility.

To access this feature, the Serial Link module is required.

Protect your harvest data and manage it from anywhere

Export your detailed harvest records at any time. Share to crop insurance agents, agronomists, or others on your farm.

The cloud service automatically backs up your harvest data to keep it secure. Access it and edit it from anywhere, download harvest reports, connect to other farm software platforms, and more!

Free and Pro versions available.

The Libra Cart system connects to existing grain cart scales/load cells and replaces an existing scale indicator with a mobile device. You cannot use both the indicator and our app at the same time. The load cell and power connectors are both 4-pin AMP. Depending on your existing setup, you may require an adapter cable. If you have any questions, contact your dealer or us.

Central City scale can provide scales if the grain cart does not have a current system.

Certainly! With Serial Link, you can easily connect to standard external scoreboard displays. Simply pair it with your Libra Cart device to view grain cart weights displayed in real-time on the scoreboard.

Libra Cart is powered using either a 3.6V AA lithium battery (included), a 1.5V AA lithium battery, or 12V power (power cable sold separately) connected to your tractor or grain cart’s wiring. If using a battery, for maximum battery life, use a 3.6V AA.

The Libra Harvest app is compatible with both phones and tablets running iOS 13 or newer and Android devices running versions 9 or newer with at least 2GB of RAM.

We recommend a tablet for the primary mobile device in the grain cart as it has a larger screen and can be easily mounted in the cab. Phones are great for remote displays from the combine or truck.

The Libra Harvest app uses very little storage space on your mobile device. When choosing a mobile device, the minimum set storage capacity is sufficient; it just depends on what else you want to use it for (photos, movies, music, etc.).

No, our system does not require cellular data or Wi-Fi. It will collect harvest data whether or not your mobile device has an Internet connection. Once you have coverage, you can share your harvest data via email and automatically to the cloud service.

An Internet connection is required to sync all harvest data from the mobile device in the grain cart to other mobile devices in real-time, either through a cellular plan or a Wi-Fi hotspot.

No, the operator does not need to tap Unload or Save. Libra Cart defaults to have automatic unload detection ON and will automatically save the date, time, weight and location of each grain cart unload. Optionally, the system can run in manual mode, in which Unload and Save on the main app display would need to be used.

The date, time, weight and location of each unload are automatically detected and recorded in the Libra Cart app, so it doesn’t matter if you unload the entire grain cart at once or halfway; everything is accounted for. For smaller unloads (less than 1000 lbs), manual Unload and Save on the main app display can be used.

The Libra Harvest app does need to be running to collect and store your harvest data; however, it can operate in the background without any interruption to your data if you need to take a call or use another app. We do recommend leaving the app in the foreground as much as possible.

All harvest data is stored in the Libra Cart app and automatically backs up to the cloud service when an Internet connection is available. Harvest data can be exported via email or the cloud service website.
Cloud Service Brochure
  1. The patent pending Bluetooth transmitter installs on the grain cart and wires to the junction box connected to the weigh-bars. An in-tractor tablet or smartphone communicates wirelessly with the grain cart to become the scale indicator.
  2. Beyond the tractor, combine and truck operators can monitor operations with their mobile devices when in range of the grain cart (hundreds of feet).
  3. Cloud-connectivity unifies the system across your entire operation. Crop flow transactions can be emailed, or optionally stored securely in the cloud for access wherever you are.

Get an Edge!

Everyone wants better, user friendly products. Companies are responding with add-ons to enhance their traditional offerings. Agrimatics has taken a different perspective, and see endless possibilities in the cloud. The Libra is wireless, there are no cables between the grain cart and the tractor, so installation is simple. Agrimatics has done away with complicated menus and buttons, and added cloud connectivity to your grain cart.
