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.
