[QUOTE="feazel, post: 2563290, member: 6771"] When SCS came out how did they calculate the spread pattern? I'm guessing they weighed every tray and threw each tray weight into a spreadsheet to give a calculated spread pattern? It is important to understand how a spreader throws fert, it will NEVER give an even spread across the width (as in it will not place the same amount of fertiliser each meter throughout its spread width) what it does by its very nature is to distribute (generally, this could differ from manufacturer to manufacturer given proprietary vane design) more fertiliser in the centre and less towards the edge. Then when you make the next pass the overlap will even it out to an acceptable level (known as the coefficient of variation) this acceptable level differs upon which standard is being worked towards, somewhere in the low teens is pretty normal for this CV value. Hopefully this wee pic explains it [attach=full]342276[/attach] Having a think about it, I'm reckoning that you take the weight from the little amazon test tubes and input it to their controller and this does the calculation in the background to work out adjustments to give a better pattern. Seeing uneven amounts of fert in each tray across the width is normal. [/QUOTE]
