Corn header loss with JD 893

Question

Have an 893 John Deere corn head on a 9770 STS. Rotate corn to beans every year and last year was the worst year for header loss with this header... Can be proven from all the volunteer corn in our beans. Any tips on how to help with losses, adjustments to look for this year?? What have others tried and worked?

Answer

Are you 100% that it’s from the header? What moisture do you typically harvest at? Do you have issues with spongy cob? My experience with the rotors is no matter what color they don’t do a good job getting all the kernels off the cob until you use an aftermarket concave system. I chose estes concaves and dropped my machine loss down to 1-2%. As far as header loss I know I’ve got some but I harvest at 22% and dry to cut the loss. Iv done test strips and let the corn dry to give check spots and it makes a difference on my operation.

Answer

Had same problem even had calmer deck plates was worse when corn was dryer than 15

Answer

Calmer stalk rolls and their sprocket slow down kits will do wonders for reducing butt shelling and header loss.  Secondly I took ************** advice and opened up the bottom sieve full open and then closed my chaffer/upper sieve down to where I kept the cobs from being able to fall throughout and there was a massive difference in how much volunteer corn sprouted the next spring.

Rest of combine after header is all OEM parts.
