Kinze soybean meter users - question - problem with see

I ran 61 units (140,000 seeds is a unit) of soybeans on Friday. The monitor pretty much read 155,000 to 160,000 per acre all day. Those soybeans were 2,900 seeds per pound. Seed dealer brought another 40 units on Saturday which are 2,400 seeds per pound. Without changing any settings on the planter or in the monitor the best I can get out of the planter is around 140,000 seeds per acre. Every row is running a low population. There are some open cells in the plate as it comes around. I am using the black plates with 60 cells. The black 60 cell plates are suppose to handle soybeans that are large clear down to 2400 soybeans per pound. Bigger than 2400 beans per pound you are suppose to use the blue 48 cell soybean plates I believe. Even through the current soybeans I am planting are larger I still shouldn't have to use the blue plate. But, I think the larger size soybeans are my problem. Also, I see that some of the soybeans have an oblong shape. Any ideas? I did clean the seed tubes with the photo eyes. Thank you.
 
I've heard talc over graphite helps. How are your brushes? If the black plates are a little wore that'll help. I keep a wore set around for seed size that's in the grey area. I also have blue plates. Seed treatment makes the seeds a little bigger that's where the talc helps.
 
Just speed up the drive a bit, if you have a chart that gives you population settings. And, don't always assume the monitor is 100 percent accurate....you may still be getting 160k seeds per acre, but the electric eye may have some trouble singulating the larger seed. As the others have said, try a row of large seed and a row of small seed for an acre and determine the population difference. Lots of variables in play here.
Good Luck!

PS....140k seeds per acre in a good seedbed and good growing conditions is still an acceptable population...at least here in Ontario.
 
I agree on the blue plates, I think the break is 2500 seeds per pound. Only problem with trying a couple rows aren't the blue plates 48 cells and black 60?

After commenting below I looked up the seed size break and you are in range. What kind of shape are your meters in. Brushes not worn or bent over? Plate cells still good and crisp? is there a groove worn in the stainless ring? All of these things can affect operation, fortunately also easy to fix.

check to see how many acres you're getting on a fill. I changed varieties today 3,200 to 3,100. My monitor dropped 20,000. km 3000 monitor. I planted a fill just to see, the acres were a smidge less just what I expected. sometimes it's just the monitor.
