I think you might want downsize just a bit or at least watch the weight of the blade closely when purchasing. I just purchased an 84" quick attach snow blade for my DX45 tractor and this thing is a monster (it was also one of the lightes ones I could find at 640 lbs) The quick attach places the blade much further out which increases the needed lift capacity as well. My last tractor was a Case DX33 which I'm assuming is comparable to your L2800 and I would definately drop to a 72" blade if I were buying for it.
Post some pics when you get it.
