"Theyre all great tractors, but Theyre in sort of a different league. I think the horsepower is similar, but the 784 will have a 4 cyl diesel and the others will have a 6 cyl gas or diesel. That will make a Huge difference even though they are rated the same. A 6 will outwork a 4 cylinder every time. Fuel comsumption will be a little better with the 4 I think. The 656 666 686 is a much bigger sized tractor with a variety of transmissions. You could get hydros on the 656. Also the price difference will be pretty big. A decent 656 diesel can go for 4-5k whereas a decent 784 can go for 7 up to 12k. The 784 is a much better loader and chore tractor, especially if it has the shuttle shift. Now they did actually make a utility version of the 656. Essentially in the same class as the 784 but with the 6 cyl motor. Not as many nice ammenities but a good tractor. I know its a lot of things to look at but hope this helps."

P.S. our 2500 is shuttle shifter -its almost a must for front end loader work!

3088 I found here along with a ton of other tractors hp ratings.

the 6xx series is basically a M updated with modern components - the old 5 speed trans plus a TA, Hydro, shuttle. All updated to handle 70 pto hp. The 6xx is generally a Row crop tractor or utility (utility is not that common). You can put front monted cultivators on this tractor. 6cyl motor Gas and Several Diesel engin's 282, 310, 312. Proven very reliable tractor with a long long history.

The 784 will have a 4 speed rande trans plys high/low/reverse trans. the std 8F & 4R - 16F & 8R with TA - also came with a shuttle - don't think it had a hydro version. This tractor turned out to be one of the better IH models.

Both really good tractors, the 6xx's 3 point hitch will lift more but the 784 should have a dual 540/1000 pto setup. The 6xx might have a 1 or 2 hp on the 784 - basically the same hp. 6xx is a couple of thousand pounds heaver.
