Don, you and I are going to have to agree to disagree on this. I think that some tractors are made for some things and other tractors are made for other things.
To me (again my opinion) the CK30 runs up against the
B7800/
B2910 class of machine, and I agree with you that it outclasses those machines (remember I said I like the Kiotis and have said it in several threads, wouldn't buy one until a dealership opens up close by, but I still like them).
I also think the 3130 outclasses the
B2910/
B7800 and would not really compare them to each other.
But I also look at size and weight and say that just for the sake of having it, there is no advantage. You can always ballast up a tractor for stability but you can't lighten a heavy one when you want to be softer on the ground.
Placing the CK30 between the DX29/DX33 seems valid, provided we consider the loader work would not require digging. Breakout force is more of an issue when digging than lifting and I would strongly favor the tractor with higher breakout force on the loader, even to the point of giving up a bit on the lift capacity if I had to (although the NH/Farmall & larger Kubota exceed the CK's loader on all counts). It doesn't do much good to have a "theoretical" lift capacity if you can't dig it out and break it free. I think FEL performance is pretty critical on that point and it is one thing that many people fail to give the proper amount credence to. The NH/Farmall loader has 700# greater breakout force, that is substantially more than the Kioti loader.
As for 3pt capacity, again I have stated on numerous threads that I think much of that is irrelevant because most every tractor on the market has the ability to lift so much on the 3 point that the front end (even with a FEL attached) can come right off the ground. The average CUT user (even an exceptional one) would probably never engage an implement on a small or medium CUT that would actually be near the top range of the 3pts capacity. Mind you I have lifted my front end numerous times, but it was with implements that were still well below the theoretical capacity. So what good is it to have the theoretical power to lift a house with the 3pt if the rest of the tractor won't cooperate? (and I have yet to play with a tractor that would).
Physical size is one of those "trade off" type issues, as size increases then the ability to maneuver tends to decrease. So longer wheelbases might make for a slightly smoother ride, but likely will trade off to a larger turning radius. Heavier weight also uses more hp to simply move and turn the tractor, theoretically yielding less available for actual implement use. Heavier does give better traction and potentially a more stable ride, but only if the C.O.G. is as low or lower on the heavier machine. Stability comes from many factors, not just weight. To say a heavier tractor is a better FEL tractor is not accurate simply because the effective use of the FEL is based on numerous factors, one of the most important is manuverability, and for that SS on a NH blows away everything except for the Power Trac articulated tractors.
I guess I would say that I am not going to convince you one way or another, nor will I try. I simply conteded, and still do, that the DX33 and the
L3130 outclass the CK30. The fact that they also outclass the
B2910,
B7800, TC29, and DX29 seems to be irrelevant because those machines are clearly outclassed by the DX33 and
L3130 and were only mentioned as examples. The fact that a CK30 outclasses
B2910 and
B7800 is also irrelevant. There is some question in my mind regarding which is better between the CK30 and the TC/DX29, but that would depend on if I was going to do any loader work, if so, I would tip the advantage to the TC/DX29 for its added manuverability and added FEL capacity. Realistically any of them (CK, TC, DX, B or L with 30hp) will pull/power the same mower deck or box blade size.
