I have only been using planters for about 4 years now, up until then I used a hoe drill to drill my milo with decent results. What is considered good singulation compared to doubles & skips?
Question #2, is to much vacuum on a vacuum planter a bad thing? What happens if I'm running 5# - 10# increased vacuum at times? How much does this affect planter accuracy?

Shag - I bought a 7200 vac deere planter in 94 - new , i never really like the vac , The first few years was a night mare for me to get use to it . I finally got handel on it -lol When I stopped to refill the oil would cool down then it wouldtake a round or two for it to settle down , I found that just one pound -- either way would effect how the drop would be .
I traded it off last year , and am SSSSSSSSSSOOOOOOOO glad . went back in time for a Kenze figure pickup - drop was perfect !
Thats what I was taking about - the drop - low vac would let seed drop out of the disk , to much and it won't come out of the disk .
We had a IH cyclo to and traded for the deere - it was a lot better than the IH on drop , but the IH was the best on soybeans , drop was perfect .
If you have 98 to 99 on your monitor - I don't know how you could get that any better !
BTW you can put a valve in your Hydr. line where to plug it in , then you can fine tune the pressure , i have one and can send youa picture so you will know what it looks like
your going too extreme by measuring the final weights/applied. you will have variance in some places due to slip and such.
if your getting 98% your fine. not every seed germinates. just make sure you dont have any triples. doubles wont impact yield, nor will skips.
Is Kinze the only planter today that is still using finger pick-ups? I know CIH is still using vacuum, what do the new Deere units use?
