round bar concaves

[cedar farm]

Looking at concaves for my 1660. I see round bar concaves are an option. Anyone know the pro's and con's?

[jass1660]

I always ran a round bar in the middle position in high yielding corn to let it get out of concave quickly. Had every other wire pulled in first concave.

Supposed to be better in high moisture corn. I have never used them as never had a problem even in 45% corn so saw no need to switch.

How are they in beans?

I only used it in corn I switched the regular back for beans. I even had a set of small wire ones I would put in for wheat. Only takes minutes to switch out, I even took the time to change vane settings between crops.

All I run is large wire with every other wire pulled. Works great in corn, not so good in beans UNLESS you put filler plates on the front two spaces,  then they work good. Filler plates are easier to pull than changing the whole concave. 

1688 with 20' heads. 45-50 bushel beans, 150-175 corn, I've got way more combine than I need, but it was cheap and super clean.

How many filler plates do you install?

2.

I see the original post autocorrected it to, from two.

Center section is all that's required but don't use it for soybeans, especially early.

In our rotary, that is not red, we use round bar for corn and beans. It’s what everyone uses around here on green combines.

That last few years soybeans stems have been green around here.

Round bars worked good with green stem beans when using spike rasp bars at the front of the rotor usually 4 bars. But I'm guessing you have the old style rotor.

Unless an aftermarket company makes some kind of spiked old style bar

Standard rotor

I wonder if a round bar concave would help an afx rotor quit spitting corn out the back. I think an afx is terrible in wet corn

Yes it did for me.

The specialty rotor was a compromise solution for tough beans but could still process corn. Round bar concave section helps send the kernels into the auger bed and is more gentle with the aggressive nature of the segmented rasp bars of the specialty rotor. In my opinion the best rotor for corn is still the original style standard rotor because it will not crack kernels like the segmented rasp bar rotors. Obviously green stem beans and waterway grass clipped as you harvest the beans cause excessive roping with a standard rotor.

Majority of corn threshing is done in the first one and a half concaves.  Pull every other wire in the first concave to get the corn out of the rotor fast, let the second two concave finish any tough thrashing, then in soybeans run cover plates on the first concave.
