Vicon Rotaflow RS-M

A Duracoat powder paint coating protects the Vicon. The result, claims the manufacturer, is a sealed and extremely hard-wearing but attractive finish.

A trailed version of the Rotaflow can be linked to a tractor. The spreader has a large capacity, taking two 600kg bags of fertiliser at a time.
Our tester comments, “We believe it has a very good spread pattern. It’s certainly a nice, consistent spread and the operators confirm that it is easy to calibrate. Rate adjustment is simple as well. We use 80 or 90 tonnes of fertiliser every year, so the machine is required to do a lot of work.”
The name Rotaflow describes the spreading system of this machine. The spreader has two hydraulically operated metering plates, each with three discharge openings providing an equal fertiliser flow from the hopper to the spreading discs. The fertiliser granules are already rotating by the time they reach the discs and this initial acceleration maintains the spreading characteristics of the material by preventing fragmentation of the granules when they hit the vanes. A lever on each disc controls the discharge point on to the discs so it can be adjusted to suit granule size and density.
Loading is the only awkward part of the operation, as the tester explains: “Being a trailed machine of such large capacity, it does have a high loading height. In fact, it is taller than me and there is no way to lower it. Using 600kg bags eases the process of loading, though it still means climbing up the front of the machine to slit the bag — but that’s the nature of the beast.”
Vicon is a division of the Kverneland Group, a family of brands and the largest specialised producer and distributor of farming implements in the world. Kverneland Group headquarters are in the Netherlands and Kverneland Group UK is based in St Helens, Merseyside.
