I recently bought a YM1510D with a FEL for the same things you want to use yours for. I like the smaller size, and it has only a 38" wide loader, because I can actually drive it into my stall doors. So now when I muck stalls, I just put it all in the loader to take to the compost bin, and no more heavy lifting! I also drive the shavings right in to dump them. I also find it helpful for stacking bales.
My local JD dealership says they will service it. We'll see how that goes when I actually need something done that my neighbors and I can't figure out. There does seem to be several people on the net who sell parts for them though. The dealer I bought it from said he can get me good prices on any parts, but he is located 2 hours away so taking it to him for repair would be a pain.
