Grain cart scale indicators are essential tools for modern farming, enabling precise weight measurement, yield tracking, load management, and data logging during harvest. They help farmers monitor crop yields, ensure legal road weights, reduce errors, and streamline recordkeeping. Popular systems include app-based wireless solutions like Libra Cart, rugged traditional indicators like the Avery Weigh-Tronix 660, advanced models such as the Digi-Star GT 560, and connected devices like the Topcon CL-55.

Libra Cart is a modern, tablet/smartphone-based grain cart weighing and data management solution from Agrimatics. It mounts directly on your grain cart, connects to standard load cells, and wirelessly syncs via Bluetooth to the Libra Harvest app on your iPad, iPhone, or Android device in the tractor cab.

Key features and benefits:

• Automatic recording: Captures date, time, weight, and GPS location for every unload—no buttons or sensors needed.
• Easy setup & operation: Plug-and-play installation, user-friendly for all skill levels.
• Compatibility: Works with iPad 3+, iPhone 4S+, Android 4.3+ (Bluetooth Smart); iOS gets priority for updates.
