We ran Deere round bar concaves last year and Loewen Wide Space concaves this year. The loss was less this year, but still have a lot of ground-up corn. The accererator has serrated bars with some wear. Maybe 360-400 rpm rotor speed.

Is there a way to reduce the kernal damage?

Thanks

We have to switch between beans and corn on a daily basis. Not very many green stems...but some early in the year (central Iowa). What would you think about replacing half of the worn accelerator strips with smooth ones and leaving 1/2 the worn out serrated strips installed? Would that be aggressive enough for beans?

Or, maybe go with all new smooth strips? Would that feed green stem beans?

Thanks,
Mike

I found on the Deere website where they have a Feed Accelerator Slow Speed Drive attachment. Basically a kit that takes the slow speed down from 440 to 320 RPM. The high speed setting goes from 800 to 790 RPM, so basically unchanged.

I think this might just work? It's recommended for edible beans, popcorn and food corn, but why not use it for less damage in feed corn? It costs about $1250, so I would like to get a second opinion.

Thanks,
Mike

We would be running about 4.5 mph with an 8 row head and 185 bu/acre. We have installed the kit from Clark to reduce the trash and it does a great job. Not much going in the machine but ears.

What head do you run? Are you pushing the machine harder?

I don't think we were running much return. The machine has a monitor for return volume, but I'm not sure exactly how much volume correlates to the meter reading. The reading was never high.

The sample was never as clean as we would have liked, but not bad at all. We would be pretty happy if we could reduce the amount of cracked grain.
