| We have just purchased a new 9660 John Deere combine. we are trying to set the combine to do wheat. we have the rod style concave for corn and soybeans in our combine. i know there are inserts that you put in the concave for wheat. how many do put in and where do you put them? ie-front back middle all over? Thanks,
john |

Alma NE | you really should be using small wire to be honest to do a good job |

Walnut Grove MN USA | I talked to a guy a few years ago when we got a sts about wheat. I asked about the inserts he said forget them, don't work. Gotta use small wire concaves which we happen to have a set for sale, thought they were sold but guy backed out. You a minnesota guy? Some Welus not to far from me. |

| okay who are you, yes i live in southwest minnesota. do thoses wire concaves fit right in there and if so how much were you thinking you wanted for them. -john |

| Just throw out that rod concave like many others have done. Go with a low narrow wire concave for wheat. I believe only one that manufactures that one is Loewen. |

Goff Kansas | 50 series concaves don't go into a 60 series, but do go the other way, just in case that is what is for sale..
i hope you have enough wheat to justify buying these concaves, i.e. at least 250 acres every yr.. if not i would use the concave inserts and get by. will not do as good as job, but realistcally prob not worth it... on the other end of the coin, if one of the rods get bent in the round bar, you have to take out the concave to straighten anyway most of the time, and might as well put the small wire back in. not all that time consuming..

SW Ontario | Well to say they don't work is not right. I am running the large bar with 2 sets of inserts in the front concave, that covers 2/3's of the front concave.
DOES AN AWESOME JOB!!!!!!!!!!!!
The thing is it depends on what kind of wheat. We are combining R47 pioneer SRW wheat and it is an easy threashing wheat. This set up is JUST AS GOOD as the small wire in these conditions.
If you don't have much wheat, or it is easy threashing, don't bother with the small wire.
If you have a bit of tough threashing stuff, just tighten the concave and close the bottom sieve to return any whitecaps and you will be fine.
My settings are:
rotor - 850
concave - 3
top - 15
bottom - 4
fan - 1000
This is in SRWW yielding 90 - 130 bu/acre, running @ 3.5 mph with 30 ft.
Our tickets at the elevator have been .4% total dockage, and we are delivering between 35 and 40 ton/hour. Losses out the back are less than 1/4% at this rate.

NC Nebraska | We're doing the same and feel it works fine. Have 2 inserts in the front side of the first concave. Then we run 3 rows of 4 cover plates in the rear on the right side and 2 rows of 4 on the left side. These plates keep the material threshing longer. |

NE SD | Interesting on the cover plates on right hand side. Never looked in the back of ours to see what was in there on that side but it was supposed to be ready to go. We used to run 3 rows on the left side on our 9650. Problem with the rotor is it wants to throw all of the material to the left side thus the need for the cover plates on the left side. We're running concave covers on the small grain concaves in openings #1,2, & 5. I would hate to try to thresh here without the small grain grates or the covers. #5 is where the return dumps thus the reason for that location.

SW Ontario | I have all the cover grates out. I don't see how they help threashing as they are at the back where you are doing the separating. My experience is that they help put grain out the rotor...so OUT they come. The theory (from Deere) is that without them they can over load the sides of the sieves so you will get shoe loss. Unless you have tremendous MOG due to a really ripe crop, you will put more grain in the tank at a higher rate leaving them out. |

NC Nebraska | Yeah it's a new deal this year I guess. Neighbor pointed out it was in this years books so we did it. I never did actually look, dad ordered them and I threw them in one day. All we had ever done was 3 rows on the left like you said. |
