Product Info

Spread according to plan

The Topcon Spreading Control solution, directed by the Topcon Athene SM-1 controller, provides accurate application control for virtually any trailed dry or granular manure spreader. Including key features such as variable rate and data logging, as well as upgradeability with weight verification and digital farm management integration, the solution is configurable to meet the requirements of any operation.

Designed under ISOBUS protocol to reduce unnecessary costs and easily integrate, the solution provides ISO-UT compatibility for display flexibility. Modular, the solution can be easily enhanced with an optional load interface (via Topcon SL2) to provide weight verification, improving calibration and operation. Plus, when coupled with the Topcon Agriculture Platform (TAP), farmers can upload various data such as soil, yield, and as-applied to improve spreading decisions. Prescription maps can be created and sent directly to the cab through TAP and Topcon hardware.
