Sep 29, 2017 | 14:50 1 When talking combines I see sieve capacity is most often mentioned as a limitation but for me with my Case combines it is mostly rotor loss in canola. Anyone see the same or is it just something I do? Reply With Quote

Partners's Avatar Sep 29, 2017 | 21:05 3 What are you calling exceptiable loss?
We are usually at half b/a in canola with the 9870..
This yr with dry conditions it was up to 3/4 bu/a..
Pods were tuff..rotor at 700 knocked it out..concave at 30... Reply With Quote
Sep 29, 2017 | 21:38 4 Partners that excellent, most newer Deers and Cases were 5 x that until checked properly. Reply With Quote
Sep 29, 2017 | 22:01 5 If I throw a sq foot pan under the combine right in the middle with the spinners on and I get about a gram of seed. I know I should take the spinners off an catch everything in a tray to get accurate number. I have done a kill stop and can always find seed mixed up with straw at the back of the rotor cage and nothing at the back of the chaffer and the loss monitor shows the same. Reply With Quote
Sep 29, 2017 | 22:05 6 If I use the pami grain loss calculator and that works out to 1.9 bu Reply With Quote

Better separation..to slow just augers it out. Reply With Quote
Sep 29, 2017 | 22:19 8 We have are rotor running at 600 so should try faster but you here of over thrashing all the time. I also notice that when the humidity goes up so does the rotor loss. Reply With Quote
Sep 29, 2017 | 22:28 9 The big 2 seem to think only HP matter to farmers.

Yes I think a few cracks is better than rotor loss. Remember when looking in a pan or at the ground that cracks might not be coming off the rotor but off the chopper.

Sep 29, 2017 | 22:31 10 get that rotor spinning if there is loss in tough conditions.

rotor(s) fast as possible without cracking Reply With Quote
Sep 30, 2017 | 00:19 11 Most challenging year we have had setting combines. I wonder sometimes about the bushels of canola that got lost out there this year with the just "set it like a always do and go" attitudes. No word of a lie we saw losses change by 10 bushels per acre in canola, same fields, same varieties, same day...different conditions. Unbelievable but I know it happened. My guess 75% of guys would have no idea. Reply With Quote

agreed . . hardest year ever . we were doing a really high yielding canola crop yesterday and got losses with a class 8 combine down from 1.25 bu to half a bushel by slowing from 3.7 mph to 3 mph . this is an 8120 case with bigger sieves than most class 8 combines . I was really shocked we had to go that slow in a 30 ft swath . there will be a lot of canola volunteering next year . this is the most checking we have ever done Behind the combine . Reply With Quote
Oct 1, 2017 | 07:11 13 We calibrate yield monitors over a scale and it's amazing when watching yield drop as speed increases. It doesn't take much of an increase to start loosing product. We run NHs and have to say I'm very with how little loss they have. This was different though with the warmer conditions. Last yr combined 58 canola with very little volunteer growing, but conditions were a lot better. Reply With Quote

we have been through that big lentil with an 8010 case . problem is yield monitors work different at different speeds . we were slowing down and yield was shooting up , but used a weigh wagon and there was zero difference that year . only way to know for sure is to flip that chopper back , throw a net under and weigh the resultsa. those yield monitors have to be calibrated for the speed you're travelling .

Oct 1, 2017 | 09:00 15 Very true CaseIh. It gives the false impression that yield goes up by slowing down. Its like driving down the hiway while watching fuel economy numbers spike up when you let off the gas. It takes a good 20 seconds for the higher grain volume created at higher speed to work its way through. Using the yield monitor to set a combine is a very tricky undertaking. Its easy to misread the results. It can often appear that less wind also improves yield. Let it equalize.

Oct 1, 2017 | 12:43 16 Hey, questions for everyone. Does a sunnybrook conventional concave allow you to pull wires out and open things up so canola can fall through? And how about rotors? We are running a 8080. It's a big investment to make in a sunnybrook but after this year wondering if it would have been better. We can't pull wires on our stock concave on our machine. I know guys running bean concaves in rotor machines or being able to pull wires out drastically improved a combines performance in that green canola straw and humid conditions. Reply With Quote
