I would agree. I think you would have to go back to an earlier model 8010 for the 7088 to keep up with it. I would not go with a 7120 either for that matter... I think you will REALLY miss that extra 10'' of width in the cleaning system.
You are running a 585r beside your 8010 correct? It was a 575r but you guys traded if I remember. How does/did the 570r compare to the 8010? Can you keep the 8010's loss under control or does the Lexion blow that out of the water consistently?
If horsepower is not a limiting factor in corn will a 570r outperform the 8010 with a 12 row head?
You are correct in our equipment. This past year we put 35' drapers on both the 575 and 8010. 575 was an 05 (no jet stream) with 1600 seperator hrs. The 8010 is an 08.
We did 300 acres of wheat, the 575 performed just a tad better than the 8010. In 300 acres of Navy's they were bout dead even. In soys..... we had reocurring problems with the 575 at 1700+ hrs (years past problems).... 585 came..... Game over.
We did not compare 12 row corn side by side with the 575 and 8010. We run chopping heads..... The C-9 just don't have the oomph needed for power. We tried a 12-30 lexion chopping head in 08..... She ran around 3mph, where without the chopping, it would run 4.5-5 in the same corn.
In 09, 180 corn at 24-28% moisture the 575 would run an 8 row chopping head at 4.2 mph consistently. The 8010 ran a 12 row at 3.5 mph in the same corn..... Had to watch monitors like a hawk, or the fan was full of corn = by by air. Shoulda taken the lower sieve out.
As for dropping product on the ground..... I can't verify.... I will say I do not trust our 8010's sieve sensors. Another annoyance, as they seem to change over the course of days. Claas has had that case closed for over a decade.
It was wet here last fall..... 710 duals on the 8010 were no match for tracks. My question is, how much was gained for this years crop by not having ruts?
Seems the evil grain cart gets thrown under the bus in that department..... but these combines with 30' chopping heads, 400 bu hoppers, can easily get 70,000 pounds on the ground.
