Combines 2388 With AFX In Green Stem Soybeans

As far as axial flows go, one of the sales guys from our local Red Power store told me one time when I complained about greenstem beans, to wind the rotor up to 900 on the high side. I said he must be smokin' something. He said "You think I'm full of it, go try it". What a change in power requirement. She sucked the greenstems thru much much better with far less effort. By the way, how in the h... do you grow 80bu. beansIJ Here in north central IA. we can't get 50 hardly in this high PH soil.

With 900 rpm on the rotor didn't you make soybean meal out of the beansIJ These are irrigated beans and Central KS. had a lot of good help from Mother Nature this summer.

Yes, lots of help from mother nature in SC Kansas this year. We had the best dryland crops since Dad started farming 55 years ago.

I think it's just a general problem with green stem beans. Cut some 50 bu beans yesterday with our old 1480 and 24' with a new Rochelle rotor. 3.0 mph was top end. However, the green guys are sighting by a fence post also. If you speed the rotor up that much you'll just have to loosen the concave way up. That alone may save you some power. Chads

we've been cutting some green stem beans running from 50-70 bpa with our 2366 and 22.5' head and have barely hit 3 mph. A friend was cutting close to us with a 9500 and a 20' head and couldn't run as fast as we were.

I don't have the AFX rotor exactly, but I do have a 2388 with rice rotor and a Stewart Steel Axceller kit on the front, which is very similar to the AFX. We cut some soybeans today which still had a lot of leaves on them and fully green stems. These were yielding in the low 70's, the moisture of the grain was about 12%. We ran at 4.5 to 5 mph with a 25' MacDon draper. We keep the engine speed above 2400 rpm. Our setup: large wire concaves with all wires still in, keystock grates with disrupters, full rice spikes rotor at 640 empty, concaves at 4, vanes in middle position. Rice spikes with the disrupters chop the stems to stop roping and get them out of the rotor quicker. Estes says to run the rotor at least 700 with the disrupters, and it would probably have done better if we ran it up faster. The draper header feeds so smoothly that we don't have to worry about slugs. We run our vanes in the middle position, but I've been told if you run the back several vanes in the fast position, it will help move the stems out quicker to prevent wraping. So what exactly is happeningIJ I never liked the 1020, seemed to slug feed too much. Is this your problemIJ Otherwise, I would speed the rotor up until I started cracking beans, then slow it down until it stops. Put the back half of the vanes in the fast position. By the way, you are correct that the new style impellers don't rumble like the old ones did. The operator must pay much more attention to engine rpms and the sounds of the machine.

Unit2; No, it didn't make meal out of the beans, they were around 13% moisture. I agree 900 sounds outrageous, must add it was a 1440 with reg. rotor, every other wire removed, maise bars over keystock grates, not the newest concave and rotor bars so that may have made a difference. The straw was hurt more than the beans at that 900 speed, sample was OK. Only ran 2 days at 900, then was able to back down to a more civilized speed of say,750. Congratulations on your yields in the KS. area!
