Combines Help Question about the Disruptor for those that have it or know about it well

The disruptors go into the keystock grate area. You also have to install the finger bars above them. The dryer the straw gets the better they cut it up. They also help elimate rotor rumble. I was in the same field as a 9500 Deere and he was talking about his cylinder growling and I had no noise or rumble in my rotor. They cost to much but are worth it.

the disrupter are available from your local case ih dealer.

Canadian Boy, The Disruptor lugs are installed in the grates rather than the concaves. There are 3 concaves in the front of the rotor which are adjustable for height to control the threshing, and 3 grates in the back of the rotor which are just for separation. The clearance between the grates and the rotor does not change when you adjust the concaves. If your machine was purchased in wheat country you may have the slotted grates, which will not accept the Disruptor. Take a look inside the machine at the rear of the rotor. If you see oblong holes with rounded corners about an inch wide and maybe 3" long you have the slotted grates. In the interest of saving money, if you find that you have slotted grates, I would just buy one keystock grate and place it at the very back of the rotor. The keystock grates look similar to the concaves and have rectangular holes with square corners formed by welded keystock material. Mount all 9 Disruptor lugs in that rear keystock grate in a spiral pattern, 3 sets of 3. As the straw exits the rotor the lugs do a nice job of chopping it up, even though it doesn't seem too intuitive by looking at them. In dry straw I would prefer it over a JD 9600 chopper which is what we were running with. If you find that you want even more chopping action, you can simply add the Rice Spice rotor bars to the rear of the rotor to run next to the Disruptor lugs. This will give you a slicing action between the lug and the spike. I've not tried this, but would guess that nearly any wheat straw would come out of the rotor very well chopped. I would suspect that with the rice spikes you will use some horsepower, but we really didn't notice much difference just running the Disruptor lugs without spikes. Bottom line: I don't think you'll be disappointed.

This fall I mounted 5 sickle sections on the left side of my grates. I made brackets for them to just bolt on and adjust clearances. I set them 1_4" away from the flat bar on the rotor as I have the standard rotor set up. It did help but some but I think I may need remove the rear grate and mount more on it. I didn't notice any power difference or separation problems.

I ran Disruptor lugs and rice spike bars this season in soybeans and corn really liked the job this combination did on the soybean stems also shreds up corn field residue pretty well. Was able to harvest both of these crops with no horse power loss that I could tell. I ordered mine from Marv Gorden.

if he has slotted grates you can get the disrupters right from don at estes manufacturing. he sell the disruptets for both types of grates

Thanks for the info. I didn't know he had lugs for both styles of grates. Wish I would have known that last year. However, I think the keystock grate may have helped with rotor loss by allowing more grain to drop through, especially in milo.
