the 7.8 is a great engine. Had one in a TR86. No issues. Case figured out their rotor with the AFX 10 years ago NH figured it out in the early 80s with the S3. I don't think the AFX is going to make up for the twin rotors. In fact I know it won't. In 50 bu durum my TR98 would run with a 1st model year 7010 we demoed. CR960 = TR98 with more cleaning area and more hp (and a way better cab)- they have the same size rotors with an improved separating section.
I have 2388 and cut in the same field with a cr960. I have a '01 2388 AFX and running a 1010 head 30' and the CR had a 35' or 36' HoneyBee. I was just helping a neighbor for a couple of days and never really went head to head but I would guess he was at least 2 mph faster than me. Untill we got to play in the mud, then I just hit the RWA and whatched him go back and forth. We switched for a while and I have no prejudice toward the NH and enjoyed running it, sure a strong machine!!!
what about if on of the 1460s had a NOS sticker and the other one aluminum wheels, while the CR970 has a big honkin' wing? Seems to make japanese 4 banger front wheel drives faster -must make a front wheel drive combine faster too!
Casefarmer: I think you have a good idea too. Its hard enough trying to compare 2 combines that are different classes. Makes it a moot point I think if you dont figure at least a 36ft draper on both machines. I know people have done it and are doing it and say it handles it fine, but I have seen it first hand where a 2388 doesnt like that big of a header. It worked but for the speed that was being driven you could have put a 1010 on it and drove a little faster and cut the same amount of acers. I know its not scientific proof and I would probably run a 36ft draper on a 2588 if I had one as well..Im just saying...
Anyway, The whole comparison of these 2 combines doesnt seem very logical. I think before one is purchased, the needs of the farm need to be figured out first.
5.5 isn't fast enuff for ya?? lol the first year we got the 36ft's we had a 50 bushel field at times 55 and i was pushing her 6.0 and my boss got onto me...but after i showed him that nothing was comeing over back and it was clean in the tank next thing i know..there he goes! haha
the same year i had a 10 bushel field all 18 acres and i was able to go 5.0 or 5.5 and i was cutting everything off and the field looked good...
she handles it good..get a 3rd lift cylinder and some fluid in the back of the tires..
Also yes the lil extra hp helps on the 2588 but not enuff to say you would want to wait a couple years get one and then get the draper..
then again i don't know your conditions... im assuming you cut your beans when there ripe. and you spay them and keep them clean
All my info is hearsay...I dont have a combine..or a farm anymore. Sometimes I wish I did. Everyone knows Johnsons and other harvesters had 88s and ran 36ft drapers so I know its possible. I have also seen a 2388 with draper have a little harder time in a field vs a 1010. Im not sure what was causing it but that combine wasnt moving as fast as the 2 with 1010s. Again..I wasnt running it, nor do I own it..Everyone..well almost anyway has more knowledge on the new combines then I do. I learn from all of you. All I was trying to say is may be a 1010 would better be suited on the 88 then the 36ft draper. Who knows though.. The bottom line is there really isnt a comparison between the cr960 and the 23/588s. Its a different machine.
OH 5.5mph..yeah thats moving along..but if you can do it at 7 or 8 mph and do the same job if not better then why not. And i know that if people report running that fast it might and probably isnt a normal occurance.
I don't think I've seen anyone else on the boards say that besides me. I know the only time I've ever harvested anything at 5.5mph with our 36' header was in 25 bushel milo that had been froze out. In good dryland wheat I'm lucky to be going 3.4, in irrigated with lots of straw it's more like 2.7. Maybe it's the way the machine is set up or there is something wrong with it, or maybe I'm just not pushing it hard enough, but I have never noticed any drastic performance gains from using a draper.
And Andy, I think the NOS sticker sort of balances out with the wing, so both machines would be about equal. The 1460 with the aluminum wheels would corner faster, though.
