Combines 1660 settings for GREEN beans

It may be kind of a dirty job, but I would suggest advancing the vanes over the concaves as far as they will move. This will move stuff thru alot faster. This setting will NOT work for corn, you will have to change the vanes back. "Disruptors" also come to mind, I have no first hand knowledge of them but I've heard good things about them.

Move vanes to fast position.

In really bad conditions I have run my rotor 8-850 or more. Consider a set of Disrupters for next year, they will help get that last 0.000001% rotor loss in corn, too. Be sure to get the hard faced serrated kife bars if you order the kit.

if anyone has any better ideas than the vanes, and more rotor speed please suggest, cause i have the same problem except these two only cause it to choke harder in my experiences. see ya'll

The Disrupters will make a noticable difference, we had a set on a 1460 with a standard rotor and even dad who never even ran the combine commented that they were well worth the money.

I designed the Disrupter back in 1995 when the green stem beans came on the scene. The new breeding of soy's was to prevent shatter from the vibration from the sickel. The rotor that you have like all rotors is very forgiving for crop damage and it is equally forgiving for the straw. The 9 disrupter lugs installed in the grate or seperating section will cut up your green stems in to four to eight inch pieces, enough for your spreader to spred the straw as wide as the head. The thumping and rumbeling will go away. It is a internal, poor man's straw chopper. There are two parts to the Disrupter set. The solid cutting lugs installed in the grate section, and a propelling device on the rotor to send the straw through to cut it up. On the conventional rotors we use the scollop bars and on the specility rotors we use the rice spike bars. If anyone has any questions please call me. Estes Mfg. Co. 1(800) 235-4461

Disrupter bar kit and make sure you have the notched separator bars installed on the rear half of the rotor and not the stock smooth ones. You said that you removed all the straight rasp bars from the rotorIJ Do not remove the straight rasp bars that are mounted between the end of the helical rasp bars and the start of the separator bars. Material will stop moving if you take those rasp bars out.

be sure it's all sharp inside not all worn out run her up to 900 on 1 or completely closed unless your cracking all the beans then slow it up to get rid of the cracks she'll sound tough but it will do the job.

Don appreciate your input. I just put some in a new to me 1660 with std. rotor. I have been around rotary machines for years and the disrupters are very impressive in sizing the bean stem. I have only been over around 15 acres so far and you can tell from the cab the cut stems. I was just looking to help getting thru with a field cultivator in the spring and I think they did the trick. Thanks

last year I was running a 1440 without disruptors and, no matter how much we speed the rotor up or tightened the concave, the green beans gave us a fit tons of power robbing rotor rumble, barely could get over 2 mph with a 15' head. This year we installed new keystock grates, disrupters, and green maize bars. Needless to say different machine, I feel like we added 50 hp to motor. I have been cutting beans with half the leaves on at 3.5 mph and no rotor rumble, last years machine would not even touch them. They do a great job sizing up the green stems and when the beans get dry I could swear the machine has a straw chopper. Replace all the parts I mentioned, which will run about $1000.00 and you'll swear you would pay $2000.00. The only problem I have is I need a bigger head my poor 15' 820 will only do a good job up to about 4 mph, a 17.5' would probably be perfect.
