Combines looks like no one can answer JD s questionIJ

[JD]

Wow, looks like I'm not the only one who feels this wayIJ Also, I'm including a post from the "Gleaner" site which has a few remarks on the CR. This guy sees it a lot like I did. I tell ya, the MF 8780xp is looking better all the time!!! JD .................................................

Has the same cab as the new R75 which is there also. I like the cab very well. Would comment that the 9690 has rasp bars similar to the Gleaner, but saw they have reverse bars which will reduce capacity. Also the engine compartment is very tight to have nice access. The smallest of the NH bumble bee CR's was there. The cab is fine too. Otherwise not impressed. Too complex. The most complex drives on a combine next to the lexions. This Fair in NW Iowa is on through next Sunday the 15th of Sept. They offer no field demo's however."

your not alone in your beliefs about the new cr combine JD. after seeing it in real time we feel the same as you do. give us the tr anytime_anywhere. this machine is going to drive away those of us who enjoyed how simple a tr was to work on and maintain. good luck if you go with massey, i hear good things about them. not so sure which way we'll end up going just yet, the 99 should last us a while. larry(Yellowfever)

A CR 940 will outperform a TR99 according to the New Holland Harvest Support Team. By outperform, I mean running faster ground speeds with minimal or no loss and a clean undamaged sample. Now, a CR 940 has a touch more horsepower, not much. Can it put a better sample in the tank and put less grain on the ground than a 99, I honestly don't know, would have to run it in the field. I have run a 960 and 970 with 8 and 12 row cornheads though so I have some experience, though I am far from an expert on CR's. I don't know who said the returns system was superior, but if you have experience with a yellow combine, you will know that even in tough green crops, such as soybeans you hardly ever run any returns because the threshing system does such a good job. This new returns sytem is merely an improvement in that it threshes unthreshed material without having to put it back into the rotors which improves grain sample even more. As for future resale values and maintenence, only time will tell. Something may look complex, but only because it is unfamiliar. Finally, I don't know what kind of combine you run, but it's funny how people knock on a machine for years about what it needs, then the company improves things dramatically, and there's still a problem with it. The CR has many knew improvements over the TR, not all of them are necessities, but JD and Case, etc. people talk about all the goodies they have on their machines and they are so wonderful. It's ironic. Don't know if you've run a CR, but I don't think there's anything right know on the market that can match it's performance. Maintenence issues will be determined in the future, we'll see what they are. If I had a new TR 99 and financially was capable and had the acres I would update to a new CR940 in a heartbeat, period.

TR, i'm curious as to what kind of combine you own and operate at the present and your pastIJ also, can you explain your following remarkIJ "This new returns sytem is merely an improvement in that it threshes unthreshed material without having to put it back into the rotors which improves grain sample even more." because in this following statement you make another analogy "I don't know who said the returns system was superior, but if you have experience with a yellow combine, you will know that even in tough green crops, such as soybeans you hardly ever run any returns because the threshing system does such a good job." so just exactly how can the "new" returns system improve grain sample even more, as you state in the first quote, when in the second one you state that,,,,"but if you have experience with a yellow combine, you hardly ever run any returns because the threshing system does such a good job." which is itIJ thanks, larry(Yellowfever)

I operate a NH TR96. I'm a small farmer but also worked at a NH dealer for 5 years. Most experience is with TR86's ,87's, and 88's. Secondly, with regards to returns, if you are in really tough beans with green pods you will run more returns than normal because of hard threshing, when you dump those tailings back into the rotors, you have more of a chance of damaging it opposed to the new system. Also if you have really dry beans and for what ever reason you are running to much tailings the new system will be less likely to crack the beans as opposed to running them through the rotors again. I understand what you are getting at, ideally the new sytem my not be needed, but more and more big operators are in the fields earlier, when crops are at higher moisture levels and harder to thresh, also many of them don't take the time to set the darn machine right in the first place. Go shuck 25-30% corn and if your worried about sample the new system will prove itself more than worthy. I would say that if you're in ideal conditions all the time and don't have any problems with sample the tailings system indeed would be a non factor.

 

[TR]

Also, one would not want to base a threshing system from the tailings sytem, as asked by JD earlier. In a talings sytem the speed is slow and there is hardly any material coming through. Centrifigal force is needed but not the number one thing for rotary threshing. A New Holland combine functions best when it is full from feeder, to sieves. Keeping the rotors full allows for grain on grain threshing, which a conventional combine can't do. The centrifigal force helps the grain on grain threshing to be possible

 

[Yellowfever]

i think you are a little confused there TR, the centrifigal force gets the grain away from the rotors and on to the grain pan. the grain on grain threshing comes from the many times that grain in a Twin Rotor machine gets carried around the rotors. as where a conventional only gets one pass at the cylinder so it has to be threshed by grain on metal. also, we have run Tr's since their inception, we are in an area where corn harvest starts at 30-32% so we know how a TR handles high moisture material. same thing with wheat, we try to start with wheat around 17-19% as it aids in helping hold onto good test weight and speed up bean planting behind the wheat. the TR handles grain easier more so than the others because of it capablities of using centrifigal force which requires higher rotor rpm's. that being said, i can't see how the new return system can handle the grain gentlier than a TR's rotors from this staindpoint. it is just like a conventional cylinder, it turns slow and has to be set tight enough to beat the grain from the heads_pods. lesson over, larry(Yellowfever)

 

[JD]

So if you don't want to base the threshing system on it why in the hell would you want it threshing your returnsIJ!IJ! Isn't it all going to the same place, the grain tankIJ And don't you want the cleanest and highest quality grain sample possibleIJ If you answered yes to the last 2 questions then it is obvious you want to drop the returns back into the rotors not only from sample aspect but also from simplicity point of view! Cause one pass on a cylinder creates the damage that John Deere's are known for! "Centrifigal force is needed but not the number one thing for rotary threshing" ReallyIJ This has been what has set the TR concept apart from the other "rotored" machines from the beginning. Yellowfever hit it on the head, centrifigal force is used to seperate the grain from the chaff and fodder. The heaviest media(grain) gets forced away from the lighter material (chaff_fodder) through the use of centrifigal force and down to the grain pan. like he said, the grain on grain threshing comes from the number of revolutions the grain makes in a twin rotor. The centrifigal force is created by the higher rpm's a twin rotor is designed to turn. Always was told by the earlier field men to turn the rotors as fast as you could without creating a problem. Your where correct though on that you need to keep 'er full as it aids in the threshing process! Good luck TR, JD

 

[Ilnewholland]

JD, I farm here in the rolling hills of SWIl and soybeans will be dry on the top ground and greener at the bottoms of hills, so how do you set the combineIJ Sometimes you can not get the green pods to thresh out but the sample will be 11%. I think the new return system on the CR could clean up the wet pods without forceing me to run the concave so close and spliting the dry beans. Because I think if you keep running the same pods over and over the returns in a TR thur the rotors they are going to get smashed up and it has to keep the capacity down on the whole cleaning system. The new combine may not be for you but for some of us it may work, but have to agree that the cost of any new combine is to high compared to what we receive in income for our production. Hope you have a good day, Ilnewholland

 

[JD]

Ilnewholland, please if you can tell me how or why do you feel that this small cylinder will do a better job than the rotorsIJ Again I state, this return is nothing but a conventional combine design. So this means in order to thresh the un-threshed pods you speak of you are going to have to have the cylinder tight enough to the concave to thresh on ONE and only ONE pass! If you do a good job threshing them you are going to have damaged beans just like you do with a conventional machine in a hard to thresh scenario, do you agree on thisIJIJIJIJ If not, I don't undrstand why you are running a Twin Rotor at the present! I have yet to understand how you figure the returns are going to get "smashed up" by putting them back into the rotorsIJ If the rotors are full of material they will be handled much easier than the new system. They are much more gentle than that little drum cylinder threshing could every be unless there is a couple of monkeys in that little drum hand threshing the returns! I can't see how you will be able to discern a difference in capacity unless the returns are overwhelming and in this case I can't see how that new little cylinder could handle this amount of material without plugging, in either case you may not need to be combining under these circumstances!! Have you tried increasing you rotor rpm's when you get into the bottomsIJ maybe by a 200 or so rpm's or more till you see a problem developingIJ Or tightening the concaves up in the bottoms and opening back up on the higher groundIJ Are you sure your concaves are square with the rotors and not in the form of a wedgeIJ When we encounter the rare occasion you speak of, here's what we do and this may not apply in your case cause we are all flat land.....we pick those green areas as soon in the morning as the head will feed. This way the moisture content is up and the beans don't get slipt up like you speak of when their dry. You may have to dry them or have a seperate tank with air to put them in. I can thresh them this way though, you end up with a lot of "butter beans" but it works here. later, JD
