Combines 8010 vs CR960 970

[Harvester]

CR is the better combine. 2 rotors are better than one. The belt drives on the NH are more reliable (at present) than the 8010s. You only have to look at them when servicing or doing maintenance, and as far as repairs, I'd rather replace a belt instead of a hydraulic line. I do wish the CR had the Case-style fan, as the paddle fan is a bit old, but it does the job alright. Both machines still have bugs to work out, but the NH seems to be less prone to major downtime in my observations of the two machines.

That is your oppinion, I will disagree I would take hydraulics and cvts over belts any day and as far as driving 2 rotors versus one I will go with one and half the moving parts.You will see the day when they drive the CRs with cvts also. That is my oppinion but you know oppinions are like an a hole everybody has one lOl.

As far as drives go the one with more moving parts you will see breakdowns at some point. More so than Hyd lines and Pumps and that CVT Drive blows the belt drive away. Gets lots better use of the power than a belt ever would and its pretty much maintence free from what i have seen. I noticed that NH guys cry about Cr not havin Capacity so they went to Concaves like Afx has so now they all cry about the Fan so how long will it be before the CR gets the Case style of fan. If you want the Genuine Article buy it to begin with is what i say since i doubt you will ever see a MX with Super Steer lOl

Just how did they go to concaves like a AFXIJ NH has always offered the small wire only, small grain concave. The large wire removable small wire, Universal Concave, and the Roundbar concave. Depending on the area different ones were popular. In my area the universal has been the most predominant as we harvest winter wheat in June_July and then soybeans and corn in the fall. You install the small wires for better threshing in wheat and pull them out for fall harvest. NH made roundbars the standard on the Corn_Soybean CR's. Now a dealer in IN is making filler bar kits which slip under the roundbar concaves and work real well running wheat. So there is no reason to have to swap concaves. And whats this comment about crying about a fanIJ The paddle fan does provide enough air. However the 970 mechanism did not reach as fast of a fan speed as the narrow body machines (940,960) do. So they are using the hydraulic fan drive on the 970's. The hyd fan does reach the higher rpms abd from the accounting prospective its cheaper to install parts that were designed to fit the 8010 than spec out new pulleys and belts on the CR970. Yeh CVT drives have some advantages but if you remember NH had some serious hydrostat failures on 2003 prebuild machines. Guess who makes the hydro drives for the CVT. SauerDanfoss does. Guess who made all of the bad hydrostatsIJ SauerDanfoss did. When a hydro system fails you are looking at 2 days of down time to flush the entire hydraulic system at a minimum and several thousand dollars per hydro unit that fails. If you do not get every particle out then you WIll (no ifs ands or buts) have another hydro unit failure. Every hydro unit on a machine adds to this possibility. From the old axiom KISS belt drives are by far the better method of providing power. As far as the comment of better use of power hydro transfer is one of the least effiecent ways to transfer power. Fluid pressure trnasfer always losses alot of energy as heat, both from simple friction from the walls of the lines and from the internal seepage around pistons in both the pumps and motors. Its just that in many cases fluid power is the most operator convinent way.

From a standpoint of the basic process of threshing and separating the CR is the better design. The 2 rotors split the load that has to travel in just 1 rotor on the 8010. This allows for both less of a physical load on each rotor and a much more even grain_chaff spread onto the pan and sieves to start with. Depending on what you want to do with it the CR gives more crop disposal options. For instance if you want to bale straw you can do this easily behind a CR. The 8010 has chopper knives mounted on its discharge beater that make baling impossible about like trying to bale behind a Gleaner Rxx series. I have no doubt that in many crop conditions the 8010 will perform just as a CR will but in other situations the CR twin rotor design is a more general all crop use machine. Just a function of overall design. I'm pretty sure FR will agree here that a 8010 is an excellent corn combine as is a CR. While corn is a major crop it is not the only crop grown. So what is best for you depends on just what crops you raise.

2 differing opinions on drive systems. From an engineering standpoint, a belt drive is about the most efficient drive system available. Every gearbox, particularly when it involves a hydromechanical system as in a CVT that employs hydrostatic power to control speed, is less efficient. And, as JHent points out, the belt drive systems are easy to troubleshoot and generally don't take days to repair as 8010s with bad CVT drives have (so far, the history of these is less than stellar). And with similar, not identical cleaning systems and drive systems, the CR970 and 8010 provide an interesting comparison when the two run side by side. The CR970 will outdo the 8010 any crop, any day, any condition; primarily because of the performance advantage of twin rotor design in its capacity and efficiency. I realize this won't be a popular opinion when expressed on the CIH board, but it is a valid one, as I've seen and run both firsthand in the same fields. I'll put money on the CR every time (the 970; the 960 is a different story with the 17" rotors). See also the distinct advantages of the other twin rotor combine in the market, the lexion, has in capacity and the efficiency of its belt drives. One has to remember that the CR had the benefit of several years of design and testing, whereas the 8010 was quite hastily rushed to market. As for swapping concaves, I don't think it is too much to ask to take 20 minutes to swap concaves in a CR. The round bar work very well and if you have to do wheat in the same day, it is pretty quick to swap them out in order to optimize the combine.

im still lost on how 2 smaller rotors are better than one...but who knows... Also i would think CVT would be alot better than a belt and the fact the head is ran by a shaft not a belt is a good advantage Also if the 2 rotor is better why didn't deere or any of the other companies go to thatIJ

Sorry I have to disagree with you when it comes to bailing behind the 8010. If set up properly it is easy to bail behind. last year we bailed 2000 3by3 weighing aprox. 800lbs with 3 diferent balers J.D. Class and Hesston and none of bailers had any problems making a perfect bail. We have actually got more people that want the straw from behind the AXIAl FlOW then we grow. Just found a new market that use the straw to make strawboard instead of plyboard. We have run the 8010 in 3 crops corn beans and wheat it will perform excellent in these 3 I cant say about any others have not had expereince.

I guess I should have got a new belt drivin tractor instead of the new CVT AGCO. lOl!!!!!!I am sure it would be alot more simple, But these CVT's are here to stay, in my opinion you will see them take place of the hydro and be the trasmisson for alot of ag products. IG
