Possibly looking for a 8560-8770 JD 4wd and would just like to know the good and bad about these tractors. will go with the 24 sp tranny and would like to find one with a PTO. Is the 70 series improve a lot over the 60? Also what engines were in this. Thanks. Have a safe spring!!

The 8560 and 8570 share the smaller block 7.6 L engine, and are good for maybe 250 HP. The 8760 and 8770 go with the bigger block 10.1 L engine and HP is upped
to 300 HP +. The 70 series offer Electronic engine control and it offers an increase of extra power when lugging, and I feel they are better on fuel also.
I had a 8770 and really liked that tractor, not one problem in over 4,000 hrs. If you can use the horses, get the bigger model. For tractors this age it comes down
to hrs. and condition.

I will disagree with that, I dont know what's heavier on a 60 or 70 than a 9000, just got out of owning an 8760 by trading to a 9300 and let me tell you, there is nothing light weight or flimsy about a 9300 so i'm not sure what your comparing to.
8760 is a really nice machine and about as solid and reliable as 4wd's get. But i'm not sure you would like the power of an 8560 (having owned both) the 8560 seems to have trouble carrying itself alone up a hill in road gear, just too much tractor for a 7.6L engine imo, not sure what your plans are for it but those were my thoughts. Ended up trading up from the 8560 to an 8760 after one season and that was just pulling a 26ft 637 and a 27ft 726 finisher.

Get a 70 series they had the bugs worked out by then. The injection pump on the 8960 was junk.I think John Deere put there own pump on the cummins and it was not good. They turned it back over to cummins on the 70.

Why must you have a 24 speed? I've seen more failures with the manual transmission than p/s
Why do you want 85-87 sizes? The 89's are basically the same tractor with one big differance; a NTC-855 Cummins is under the hood and there's a few 89's on tractor house with PTO listed.

That'll be 400hp that you'll be able to work with too. From my personal experience, that tractor can pull a 36' Landoll disc with a double rolling basket harrow all day long. It doesn't have a pto, but like Fla Veggie mentioned, you can find them with pto's on Tractorhouse.
