Got a problem with my New Idea 323 1 row picker, I just can't figure it out, when I pick with it I'm losing TONS of corn with it, it is knocking kernels off every single ear, some ears it has ground off over a third of the way up the ear, I've tried everything, moving the rollers out and in, so for in the stalks were clogging, I've speeded up, slowed down, nothing seems to help. I hate to use the thing because of it, the corn I picked Saturday was about 17% moisture but it doesn't matter if its 22%, still does it. I've seen youtube videos of 323's and it looked like the corn was pretty complete, my neighbor has a NI model 7 or 8 and it does great, most of his cobs have all the kernels. What can I do? I wouldn't pick cob corn but some of my customers want it instead of shelled.
