I have had a similar Vicon for well over a decade and use a lot of fertiliser per acre on all kinds of fields, some quite steep which striped terribly with drop and bat type spinners, yet I’ve never yet striped a field with this machine. Its easy[ish] to set up using their sieve box and charts [choosing the nearest to the sieve box results and density if the particular product is not in the charts] and if the driving width and width setting on the machine match, then it just does not stripe. Most of the fertiliser I use and in the 18m width I choose to spread, requires a disc speed of 750 rpm and it doesn’t matter what combination of engine revs and PTO ratio I use to achieve that speed. Keep the revs and width consistent with the advised settings and its guaranteed to spread accurately.From experience on the forum I realise that not everyone reads the manual and understands how machines work. In this case the main issues I can think of to cause striping, apart from poor day to day setting, is the actual initial basic setting of the machine’s exit curtain. This needs an initial setting according to the book and a daily check to ensure that the openings on both disks are consistent and in the correct place relative to where they should be according to the lever position. Secondly that the gap between the stainless steel exit curtain and the spreading disc is no more than a millimetre or so all around, so that no fertiliser escapes under it and that all is ejected through the actual gap where it is meant to.This is all in the operator’s manual.</blockquote>
