Concentric delivery system adjustment
Via the delivery system, the fertiliser is gently fed-on extremely close to the centre of the spreading disc. At this point, close to the centre of the disc; the peripheral speed is low resulting in a particularly gentle treatment of the fertiliser. For the adjustment of the spreading unit to different working widths and fertiliser types, the delivery system is swivelled electrically around the centre of the discs (concentrically). The distance between the feed-on point of the fertiliser and the centre of the disc always remains the same. The swivelling of the delivery system provides you with a wide range of possible working widths; just three sets of spreading vanes cover working widths from 15 m to 54 m.
