Precision in spreading is vital for modern farming. The Topcon Cab Control app improves weight scale control for both Landaco and Bunning spreaders. By integrating the Spreaders ‘Weight Scales’ or ‘Loadcells’ with the Topcon SL2 Scale Controller, the app delivers real-time, accurate weight data directly to your mobile device or tablet. This upgrade is ideal for owners and operators who want better control over material distribution and to control how much you load the spreader.

A Single App for Two Leading Brands
The Cab Control app works seamlessly with both Landaco and Bunning spreaders*. Whether you are using a Landaco spreader or a Bunning Spreader the app provides a consistent and reliable weight readout. It eliminates the need for separate systems by offering one solution that fits a variety of spreaders. This means less training and more flexibility for mixed fleets and diverse farming operations.

How It Works
Modern spreaders are fitted with high-precision load cells that measure the weight of material in the hopper. Traditionally these readings are displayed on a fixed in-cab indicator. The Topcon Cab Control app connects to these systems via Bluetooth. This wireless connection transfers live weight data from the load cells to your smartphone or tablet.

Key Benefits
Using the Cab Control app brings several advantages to your operation:
**Please note: For Spreaders equipped with a Athene Spreader Controller with the Digistar integrated, the full range of remote control functionalities may not be available.
Getting started is straightforward. The Topcon Cab Control app is available for download on both the Google Play Store and the Apple App Store. Farmers and contractors can simply search for Topcon Cab Control on their preferred platform or use the following links:
Once installed, the app pairs with your Spreader’s Bluetooth, providing you with real-time data and control right from your mobile device. This seamless integration means you can quickly begin managing your spreader’s load more efficiently, whether you’re on the move or in the cab. Enjoy the convenience of having precise weight data at your fingertips and transform your operational efficiency with just a few taps.
Choosing between modern digital weight management and traditional in-cab indicators depends on your operation’s needs.
This system is ideal for:
• Contractors managing mixed fleets of Landaco and Bunning spreaders
• Farmers wanting to upgrade older equipment without replacing spreaders
• Operations requiring precise material tracking and documentation
• Businesses transitioning to precision agriculture and variable rate technology
• Anyone seeking better visibility during loading operations
The Topcon Cab Control app is compatible with the following spreader models equipped with the SL2 Scale Controller:
The system can be retrofitted to most Landaco spreaders equipped with load cells. Contact our team for compatibility confirmation on older or specialised models.
The Topcon Cab Control app is brand-agnostic and works with any tractor make or model. The system connects via Bluetooth to your smartphone or tablet, regardless of whether you’re running John Deere, Case IH, New Holland, CLAAS, Kubota or any other brand. This flexibility is perfect for mixed-fleet operations.
Landaco load cells connected with the Topcon SL2 provide digital precision measurement that is significantly more accurate than traditional in-cab indicators. The load cells can deliver weight accuracy as great as a ±0.5% of reading, ensuring you have exact material quantities at all times. This precision is particularly valuable for variable rate spreading applications where dosage accuracy could directly impact performance and cost efficiency.
The Topcon SL2 Bluetooth connection maintains reliable connectivity throughout the cab and immediate surrounds. This allows you to monitor weight readings and control functions while loading from inside the cab, outside during hopper filling or from the tractor platform.
