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.

Yes, we have distributors who are scale experts and can provide retrofit kits for your grain cart.

We don't support using an external remote display, but we have a remote display feature built into the app. You can view live weights and individually tare the weight on other mobile devices within Bluetooth® range of the cart. This feature helps calibrate the yield monitor in the combine.

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). If using a battery, for maximum battery life, use a 3.6V AA.

The Libra Cart app is compatible with both phones and tablets running iOS 12 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 Cart 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 Cart 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.
