Vari Feed

Variable Rate Control for Planters


Designed for use with multiple-row planting machines equipped with applicators applying liquid fertiliser directly during planting operation. The Vari-Feed motorised valve can be controlled to supply variable volume rates at each outlet.

The valve can be used in conjunction with variable rate software / application prescription maps where different volumes are required within a row or in a lateral distribution.
