I know it is a 2003 and has the 12.5L engine with 375hp. Bigger rotor belt. Anything else different? I understand that it was the precursor/prototype of the 9860. Does it have some of the other 60 series improvements?
Thanks for any info.
You basically have it, no 60 series stuff though, nor high unload rate.
The rotor belt is larger because the sheaves are much larger in diameter giving much more surface area for friction, still the best drive in the industry.
And welcome.

Hello everyone, thought Id give my thoughts on the 9750sts special, jd manitoba you are correct about rotor drive issues on these models, they run the same size sheaves as the 9750sts north america, along with that they run a special sensor to monitor rotor drive pressure, too much load will cause the overhead display to alert operator to slow down.This was also true of early build 9860sts, you can convert these to the larger sheaves if needed. The earliest 9860sts I have worked on is serial no.706238, a 2004 model , this machine has the large sheaves, the serila no. range that tom turner posted is correct when the change occoured.Also the couple 9750sts specials i've seen in our area have the h.u.r auger, so not alot of differences between a 9860sts and the special. As far as the question about the 9770sts having small or large sheaves , as of the 70series all class 7-8 machines have the large sheaves.460 your 9660sts will have the same size as a 9670sts or 9760sts.

Are you guys sure about the bigger rotor belt? I don't think its as big as the 9860 belt. A local hutterite colony had 4 9750s with the 12.5L engine and they had a 1 or 2 spare belts hanging on the blinker and I think they had almost a pickup bed full of burnt belts at the end of the season. I would seriously consider if it is worth it or be better off with a 2004 9860 (which never burn rotor belts)

We are talking about the 9750sts Western Canada Special combines.
These Combines have all the features of the 9860 ie. Same drive belt, identical rotor, mine has never once smoked a rotor belt, I replaced it when I first got it just to be safe (I didn't want troubles during harvest) the parts guy gave me a regular 9750 belt the first time, it was only 2/3 the size of mine. So I took the old one in with me and the parts fella thought I had a new one. He ran the belt number and told me that it's a 9860 belt. I blew the 2 beater belts once, but John deere has a kit to upgrade the beater drive to a 3 belt setup identical to what the 9860 uses.

These machines will do every bit as much work as a 9860sts hands down!!!! I ran alongside with 4 9860's while doing many thousands of acres worth of custom combining the first year with my 9750 Canadian class. The 936D 36' header seems like nothing to it!! The Canadian special package was phased out and then relabeled as a 9860 with a few minor updates 2 model years later. The unload augers look identical side by side. The frame is substantially thicker that a normal 9750sts, factory bin extensions, BIG RUBBER, and a way bigger fuel tank. The engine is so much smoother to operate, it's quieter and the manifold doesn't break every 2nd year like my normal 9750sts. The Canadian class combine is actually easier on fuel in the wheat, due to higher throughput and a 6' wider header meaning less trips up and down the field. And oh the way it eats tough Canola is nothing short of amazing!!!! It will pass all of the conventional combined, 9600, 9610, and my 9650 (which is junk).

The list goes on!!!! But the final factor is that the Engine is identical to what the 9400 4wd tractor uses. This engine is much less troublesome than the normal 9750sts engine which just smokes all the time right from factory.

In summary the 9750sts with the Western Canada Special package is an absolute grizzly bear in the field, and a true pleasure to operate!!!!
