Kuhn ramps up headland fert spreading accuracy with Optipoint Pro

Kuhn has further developed its Optipoint fertiliser spread pattern control software for even greater accuracy at headland intersections.

Available for the Axis range of twin-disc broadcasters, Optipoint Pro adjusts the drop point – where fertiliser flows onto the discs – to shift the pattern outwards from the field boundary as the tractor turns on to the headland tramline.

The field-side disc spreads wider, while switching the boundary-side disc to a border spreading configuration.

Performance tweaks

Tailored settings are available for the variation in ballistic characteristics of different fertilisers, offering an increase of up to +4 drop point, or up to +60% application rate, with lateral distribution also taken into account to maintain an even spread pattern.

Kuhn says the system will prevent inaccurate dosing on headland turns, which will be especially helpful in awkward-shaped fields and short work situations.

Optipoint Pro has been incorporated in Axis VS Pro spreader builds since September this year.

It is compatible with all isobus terminals and a future development will enable users to view coverage maps.

The spreaders already feature Electronic Mass Control to individually monitor and adjust application rate from the two discs.

This ensures accurate variable-rate spreading across zone boundaries, with “W” versions also incorporating load cell weighing and continuous rate calibration.
