Kingston, Iowa | Re doing my Spra Coupe with aluminum booms from Mako ( made by Pommier ). Replacing all of the dry boom equipment with wet boom stuff. The easy math is 48 nozzles. Every online source/calculator I've seen is 48 nozzles, Mako quoted me 48 nozzles when I bought the boom frames. A friend at the fertilizer dealer counted an even number of nozzles on their 120ft sprayer boom.
Now what has me perplexed. What little I know about spray nozzles is that they should overlap to get the right coverage and spread of particle sizes. One source said 50% overlap. 48 nozzles at the correct height above the target isn't going to get full coverage at 80 feet width. It's going to get me 78' 4" at full rate and 10 inches at both ends of half rate. The old boom had an odd number of nozzles on it, so around 2012 AGCO must have thought the same thing.
Which is right?
I'm hoping this stirs as much debate as test weight vs yield.
I already know what is going to happen on mine. It's going to have 48. Mainly because an odd number of 20 inch spaced nozzles won't fit in the boom right. 15's might, but I don't want to spend the money on the extra nozzles. As much as this old coupe wanders and flops around anyway it will be exceptional if I only have 10 inches at half rate! | |
