Combine capacity comparsion

We have moved up very gradually with our combines over the years. When I was small, I do remember the old, self propelled Massey Harris combine we had as well as the mounted picker and shelling unit on our 450 Farmall. We went to a 545 Oliver self propelled combine and ran that for a number of years. Our next step up was a 7700 Deere, which was also used for a number of years. We used a comparable sized 20 Series Titan for a couple years before the last upgrade, but it was not a significant increase in capacity as compared to the 7700. Some time ago, we migrated up to a late model 9500 Deere combine with a 6 row corn head and 925 flex head in soybeans. This was a move we have not regretted, as I am impressed with the greater capacity of this machine in both corn and soybeans. My one comment about the Maximizer machines is they tend to be a bit rougher on the crop itself, as there is a bit more damage to the crop, however the sample is cleaner as compared to the 7700 and the 20 Series Titan. I have watched others who have moved up to the Deere STS combines and it did not appear they gained a great deal in terms of threshing capacity. So my question is, to those who have moved up from a 9000 Series Maximizer to a later 9000 Series STS machine, what has been your experiences? How does a 9500/9510/9550 conventional combine compare to a 9560 or 9570 STS combine, or a 9600/9610/9650 conventional combine compare to a 9660 or 9670 STS combine?
 
There is nothing you?ve said I agree with. We ran three 8820s at different times and all three of them put out a better sample then the 9600 we bought later on. Capacity of the 9600 was only very sighlty better then the 8820s. Then we had a CTS II which matched the sample quality of the 8820s and capacity of a 2388. From there we rented a 9760 STS then moved to two 9770s and several S670s. Capacity wise there is no comparison. The STS will pound a 9600 into the ground. A 9600 cannot handle a 40ft header in 40-60 bu wheat or 80 bu barley. Sample wise the STS will do just as good if not better job then a 9600. Far as I am concerned the only redeeming feature of the 9600 was moving the cab back to the center. Still have the third 8820 and a 7700 a neighbor pawned off on us.
 
I appreciate your comments, greenenvy. I have never been around wheat or barley in any machine. My question centered on corn and soybeans. What we have experienced with the prior machines were more unthreshed pods and pieces of stem in soybeans, and a presence of smaller diameter stalks from the top of the plant and bits of cob when harvesting corn. I do believe the rotary combines are more forgiving in threshing when not running at full capacity, versus a conventional combine. I have ridden with friends of mine who have Case IH rotary combines of comparable and larger size to our 9500. I have watched neighbors who have the Deere STS machines, but never rode along with them. When the 9500 first arrived in 2002, we had talked with those who had operated them in our area, a custom harvester, along with a technician from the dealership where we purchased it, who guided us in initially setting our machine the first year we had it. We did have an 8820 Titan (after the 7700) and ran it for 2 years before purchasing the 9500. The 8820 was a bit disappointing, and in retrospect, there were a variety of reasons for that disappointment, which I will not go into. We opted for the 9500 based upon conversations with others who had owned and operated these machines, and could utilize the heads we already had for the 8820. From what you shared, you moved up one size in class from the 9600 to the 9760, 9770, and the S670, whereas the 9600 was produced to replace the 8820 by Deere. I was simply inquiring about what others have experienced in their upgrades from the Maximizers (and their replacements), which were conventional machines, to the comparable sized STS/Rotary machines in corn and soybeans. I wasn't so much interested in small grain, since we do not raise small grain. I do know the earliest rotary combines produced by IH and Case IH were known to have their challenges in soybeans. We witnessed that in our own fields with neighbors who we hired to help harvest in the days before we purchased the 7700. One of my closest friends, who is on his 3rd Case IH rotary combine, shared with me his IH 1460 rotary combine was handicapped in soybeans until he updated the rotor to the Specialty Rotor, which (in his opinion and experience) finally made his 1460 a very good machine in soybeans. As I recall, the challenges he encountered with that machine became more prevalent when soybeans developed larger diameter stems, which were green, wet, and would not dry out. His subsequent machines (2366 and currently an AFX 7230) are great improvements to their predecessors, according to him. Again, I am looking for comments/experiences on similar "class" of machine, and conventional versus rotary/STS in the Deere lineup, specifically in corn and soybeans.
 
I cannot answer to the green color but I went from a 750 Massey conventional to a 1660 rotary which should have been comparable sized machines. But for parts availability, I was disappointed. That Massey would have ran circles around the 1660.

Hey Silverado
I to have had most of the same machines that
You have had
Let me assure you that an s670 will do the work of two
9500s
I picked corn a few days ago for 7 hours and
Totaled up what we hauled in
We shelled over 22,000 by in seven hours
Try doing that with your 9500
 
It seems my comments prior to my questions rubbed you the wrong way. I don't think I suggested my 9500 could keep up with your S670, since they aren't in the same league as one another. I accept your combine is bigger than mine. By no means were my comments meant to offend anyone. I also do not operate nearly as large and as modern of a farm as you do, either. I am pretty "small potatoes" compared to you, as I certainly could not justify an S670. I am an evening/weekend/part-time farmer, as I have an off farm career I would be a fool to give up at this time, but when I am in field, I want things to work and work well. Your figures of harvesting 22,000 bushels in 7 hours being about double what my 9500 will do are about dead on. I do not need that kind of capacity. I do remember the days before IH/Case IH came out with their specialty rotor, the rotary combines in our area struggled in soybeans, as compared to their conventional counterparts. I have watched others with their machines, and the one neighbor who replaced their 9500 with a 9570 STS did not seem to make a gain. With the same head on our respective machines, it appears I can outrun him with our 9500, and I know I am in a higher yield environment, based upon my one on one conversations with him. I desire a rotary combine simply based upon their being gentler on the crop, supposedly being more forgiving if not set quite right (based upon comments my friends have made who have rotary combines), less complicated for service/fewer moving parts, and rotary combines being most prevalent now. Considering there were an incredible number of 9500's in our area for a number of years, there are not many left anymore. I was troubled to find the shaft driving the cleaning shoe supply augers is a part not commonly stocked in dealerships in the fall, when ours broke last fall. I am contemplating an upgrade to a late 9560 STS or 9570 STS. It was my hope to find some others who kept within the same class machine, moving from conventional to rotary, and what their experiences were with this upgrade. So with that, I am sorry my comments and questions upset you in any way.
 
had a 8820 sence 1990 [ best deere ever made] 25' head 6row cornin 120-130 bu corn two semi's couldnt keep up.. then got 9610 no better just newer no more capaticy, 8820 burnt this year so I got a 9600 to replace it had no choice, grandauther runs the 9610, i run the 9600 two son's drive the semi;s....no grain cart
 
The 9600 has a shorter concave. The air blast is aimed more to the front of the cleaning shoe to hit the grain as it comes off the concave like a Gleaner.
 
The 9600 has a bigger longer concave then the 20 series.
The cylinder diameter is 26? vs 22? on the 20 series therefore
the concave has to be longer. And on top of that the concave
on a 9600 has a bigger degree wrap around then it does on a
20 series. The concave area of a 8820 is 1,328 sq in while
the 9600 concave is 1,504 sq in. Both concaves are 65.5?
wide.
