I've had a SC2400 for almost a year now. We've got a few acres of mowed grass area, complete with hills, trees, ditches, and other obstacles.
I've been more than impressed with the maneuverability of the tractor. I've got the rears filled (Rim Guard) and also have them swapped to provide for about 4" extra width. This has greatly improved stability on the hills. The thing seems to turn in much less space than I thought it would. I've got the R4 tires, and if the turf is wet they will cut in a bit on the turns. Not a problem though unless it's just stopped raining.
The deck seems to give a very good cut, although for me the 60" width proved to be a problem. My trees just don't want to move out of the way. The cut quality itself is better than my JD 318 ever could do, even when it ran right. Of course, with a 60" deck, any high spots will have to go through a bit of "training" until they are even with the rest.
The only complaint I have with the deck has been the powder coat that was applied to the underside, which doesn't seem that keen on staying put and is flaking off. Not just the usual wear & tear - it seems like the metal wasn't prepped properly.
I don't have the blower since I've got a gravel driveway, and flying gravel and windows just aren't a good match. I do have the front blade, which uses the same front hitch. So far I have not found a limit to its usefulness. I'm in the Milwaukee area, and so far we've had over 40" of snow to move. The 12" heavy snow we had last month was no problem, although I had to make my first pass on a downhill run. I just couldn't get enough traction going uphill, even with chains. The problem was the gravel moving, not so much the tractor itself. I tried to clear the first snow with a rear blade. It's like night and day comparing a front and rear blade for clearing snow. The front blade is the way to go.
I've not had any experience with the blower, but the unit certainly has the needed power. They also have a heated cab if you need.
After a bit of practice, I can remove the front hitch/blade and have the FEL back on in about 10 minutes. I've swapped them out often, as I need the FEL to pile the snow and move the snowbanks around so we don't get closed in by snow.
