Combines My research on TR vs CR s

[rasphead]

I demoed a Cr940 in corn with 8 row head. I presently own an CaseIH2188 and JD 9510. Wow- I was very impressed with this Machine. Best Cab I have been in-hands down. The self- leveling shoe and the adjustable sieves from the cab were very impressive. I hae never thought much bout NH Machines- but I have to Admit this thing amazed me.

Thank you NHDon for your report. I think JD may come around in time after he sees and drives a CR. JD, I hope you don't take this the wrong way, but talking to you is like talking to my dad. I take him to farmshows and show him something new an he sees nothing good about it, and after I buy it and he uses it he is telling me how good it is and we should have had it a long time ago. Makes me want to pull my hair out! It really has been a joy talking to you JD and I wish you best of luck in whatever you buy in the future. Ilnewholland

 

[JD]

Afraid not Ilnh. I don't buy into this contraption. In time I think you guys may come around too, just the other way. I wish you would try to explain what I asked you below, but then again maybe you can't cause you are a team player ))IJ 10,000lbs heavier, more complex drives, return system from the 60's, $25,000.00 more base price....oh, but it has a nice cab.....whoopie, call the dealer and lets get one on order if that's the case, that TR's cab is killing me has always been echoed....:-o Nope I can't see one advantage to it being I have all flat land, sorryIJ You be good, JD

hey JD, i can hear NHDon, Ilnh and the others chanting from here, can't you.......new holland is good, the cr is great, newholland is good, the cr is great................... here's something that's puzzlingIJ NHDon states this below "Thanks JD!!! You expressed my centiments exactly. The dealers and the new managementhave wanted to join the pack instead of leading the pack for sometime. Earlier a wrote you a reply that expressed my feelings better but, someone thought I used some offensive words do they wouldn'tlet it go thru.By the way te CR-940 weighs about 10,000 lbs.more than a TR-99" and then this "JD, you and I agree on a lot of this. I don't blame the engineers for wanting to be like the big boys. I see it as the dealerswanting to have something to offer that is not innovative or controversial. Many farmers, especially young ones are so "green" that even there shorts must be green. Believe me John Deere doesn't make thebest machinery, especially combines." now he is carring the CR flag around, whas upt wit datIJ larry(yellowfever...no more)

JD, I have had TR's sence 1977 so maybe that makes me a team player, I don't know. I have about every other brand of stuff on my farm as I try to buy what works at a good price, so that means not to much John Deere on my farm. Most of my tractors are Agco as most of my New Holland dealers or also Agco dealers. I can see that the CR does not have much value to you because you have all flat land, but some of us are not blessed with good farmland. In one 20 acre field I can have 5 different soil types, so the beans don't grow the same across the field. In one pass I have 4 low spots and 5 hills to cross so to keep setting the combine is not easy to do. I have use a concave of 3 and a rotor speed of 1250 rpm to get wet pods threshed out this year as we were very dry all summer and beans on hiltops were popping out and low spots green. Some seed beans were 9.5% and had green beans and pods in the sample. I grow seed beans and I tryed everything I knew to get a good sample this year but was not the best I think it should have been. I just hauled my seed beans in today and they said that they were good for this year, but my cleanouts were almost double from last year. This year we had 10 to 40 bu beans in the same field so it was very hard to set combine and to run it full all the time. I see more value in the new CR's to me. New Holland has been good to me and every TR that I have owned has been better than the one before and I see the CR that way too. I may be wrong, but time will tell. Ilnewholland

WOW, you guys are really hung up in "buzz words" aren't you. First of all centrifugal force (as NH typically advertises, the corect term is centripital)does not cause separation of grain from chaff. Basic physics- grain (high mass),chaff (low mass) are accelerated at the same rate by the rotors. What causes separation is the grain passing by while the crop material catches (friction) aganst the concave grates. Second-threshing is not due to grain on grain. The threshing in a rotor is done exactly as it is in a conventional cylinder. The rasp bars beat the crop material against the concave. The difference is that a rotor can thresh much higher amounts of grain as the material has a much longer threshing area to cover lengthwise in the machine and fairly equal distance circumfrence wise as a conv cylinder. The rear portion of the rotor does the lift and separate duty that is perfomed by strawwalkers in a conventional machine. So basically the rotor does the complete job of a conv in a much more compact unit with higher capacity. The twin rotor design has a number of advantages over a singe rotor. The small dia rotors run at higher RPM's thus more inertia. That combined with exchangining the loaded area of the threshing mechanism from left to right rotor makes it nearly impossible to slug. The conterroting rotors also eliminate the possiblity of roping as crop material attempting to rope on 1 rotor will be pulled apart as it crosses around to the other side. Also the separting section is more fully utilized where in a larger singe rotor the upper area and around the opposite side from the lifted side is basically unused. The majority of crop_grain separation in the rear of a rotor will occur as the threshed crop_straw is first lifted allowing the grain to fall loose. Overall the twin rotor has a significant advantage over Axialflows, MF or JD STS rotors and Gleaner itself accually uses a conventional cylinder design for threshing and a more rotory pricipal for separating. As far as the CR, looking at a CR940 there are really very few big changes. In fact it may even have a main drive belt or two less than a TR. Basically all the same mechanisms are present however the hydro unit and separator are now driven out of the engine gearcase instead of a main drive belt. A number of drives that were on the right side are now on the left by the engine drive. Really the only thing more complicated is the tailings drive 90 degree gearboxes and driveshaft. Thinking about it like you were an engineer, the simplest way to run the tailings was the way it was done. To have used a long elevator back up to the front of the rotors would have been just as complicated with the selfleveling sieve frame and more prone to clog as the material running up the tailings is not always the easiest stuff to auger. Somewhere ther would need to be a hard to design transition point to the elevator. I especially like the way the sides are open to the top of the rotor case from each side now. This will make them much easier to keep clean as this is the most often sorce of fire on older TR's.

Hey Ilnh, Are you near Newton ImplementIJ I talk with a salesman from there every so often and just the other day he was telling me how dry you guys have been for, like the last 3 yearsIJ It's tough everywhere, so nobody needs to feel unique in that matter! When we pick seed beans for a company or ourselves we pick them on a damp_cloudy day or early mornings so as to keep the moisture up. The company I raise seed for doesn't even want them if their below 11% and they pay a premium if you keep them between 13%-15%. But, they require you to have tanks with fans to keep them cooled down. There guy comes out and checks the moisture every other day for you so it's not any trouble. Hey, I meant nothing personal above...just trying to lighten this subject up some! JD

 

[JD]

Yep, that's the exact hypothesis! Now engage it into reality and your down to our levelIJ Things are oh every slighty changed by that aggravating thing called gravity. Your right though, 2 small rotors are better by design and principal than one large one. Good day, JD

JD, About 50 miles SW of Newton, this year was the wettest spring I have ever saw and then one of the dryest summers. So it has been a looooong year. Can't wait for it to be over as now I haven't been in the field for a week as it is wet again. Most times they don't want seed beans below 11% but this year they didn't say anything, so I think everyone must be to dry. I tried to run bin fan on damp days but could not get beans any wetter. Wheather here in mid Oct was dry so there was no damp days to combine now been rain every day for a week. Just been one of those years. later, Ilnewholland

NH is in a class all their own in every way except sales or market share. They have a superior combine. So I say get out and demo these CR's to farmers that haven't seen the light!!
