RotaFlow Spreading System

The name RotaFlow describes the spreading system; the fertilizer granules are already rotating when they reach the spreading vanes on the disc. This initial acceleration of the fertilizer prevents fragmentation of the granules due to impact with the vanes and maintains the spreading characteristics of the material.

RotaFlow spreaders feature two hydraulically operated metering plates each with three discharge openings. This ensures an equal fertilizer flow from the hopper to the spreading discs.

Accurate spread pattern in all situations
Accuracy on slopes is one of the strengths of the RotaFlow principle. The special discharge chamber prevents fertilizer from falling on to the disc and being hit away by the vanes directly. The fertilizer always contacts the discs at the same point thus avoiding striping.

Situation            Vicon          Competitor X        Competitor Y
Level ground :    7,0%                 8,3%                      15,4%
Up hill :                8,3%               32,3%                      23,8%

Border spreading
All RotaFlow models can be supplied with two options for border spreading: border spreading plate or tilt cylinder.

The RS-XL and RS-EDW are also available with the TrimFlow border spreading system. The TrimFlow can be accurately set for all types of fertilizer and for all working widths. Operation is easy, no need to leave the tractor seat.
