I think you will be impressed with your new SB setup. I have used their cylinders for 15 years but not the new concave. I think both components contribute to more complete threshing, right up front, before partially threshed heads get into the cleaning system, which then have to be rehandled as returns and would contribute to overloaded return and more cracking of grain. I think that having the ability to keep the grain inside the concaves until it is 100% threshed is very important. Remember you can increase concave clearance and/or slow down cylinder speed to decrease agressiveness, but in hard thresh conditions you have the ability to adjust the other way and not overload the return and not have unthreshed grain following the straw out the back. I use the 6.5 mm aps grates with keystock and Intensive thresh segments in for wheat, barley and canola. I have left the deawning doors open but in hard thresh wheat you could close them. My 480 has a corn concave with oval shaped 18 mm slots. I made 4 rows of filler plates that bolt on the bottom side of the concave and work well. Almost no rotor loss. I just leave them in all the time, but I am not doing peas, where you may want to take them out. I do not like fillers on top of the concave because the keystock does not do its job if not fully open.stsdavew said:
I run a 585 in usually tough wheat conditions. I use the small grain keystock aps grate with disawning plate closed i found i got more returns with it open. I use the intensive threshing segment and no concave filler plates and have not been happy with the sample. My concave is not the proper small grain concave though. It is one used for wheat and corn kind of an inbetween i was told. A friend of mine has a 595 with the same concave except he has 4 of the concave filler plates installed and no intensive threshing segment and he does get a better sample than i do. Ive ran this way two years now and if i want to get a real good sample i have to return a fair bit and i feel i get a little too much cracking. After this harvest for what its worth i bought a sunnybrook concave and cylinder... Hopefully next year i will Be happier with the sample.
