I was told the same thing about the tires. I have the SU with BIG FEET. I can't put my hand between the top of the tire and the fender. VERY tight, and a PITA to clean inside the fenders. But it'll nearly climb a tree at idle in Low, and plenty of ground clearance. I traded the mid PTO for the better rough terrain performance. Rears are filled too, so each rear tire weighs nearly 700 lbs. Very seriously considering a set of 2 or 3 inch spacers, but will definitely have to do something different for a box blade if I do. Already have a problem with a 4' blade behind the big feet. I feel pretty confident it could pull a 6 footer.
Don't really need a cab down here. Usually, if it's cold, it's also wet and muddy. We have a pretty mild winter. Not Florida mild, but mild enough. Most of the noise is under my butt anyway (hydrostatic transmission), so not sure a cab would help that much for noise. Nothing to base that on, however, other than reviews of those that do have cabs. I'd likely break something on it because I go under a lot of low brush and get close to trees a lot while doing my thing.
It'll be a long time before I can use a mower where I spend most of my time with the LX, and when I do get one, I'm resolved that a 3PH mounted one will be better for my use. Unfortunately, no bagger with that, though. Got water oaks in the part of the lot that I mow, so a bagger is really handy. May wind up having to get a PTO driven yard vac if I retire the Husqvarna or it wears out. Don't really want to 'mow' the yard twice to get it cleaned up, but the way I see it, that's more seat time and boredom prevention. I usually get the missus riled when I get bored, or worse yet, go spending money.
