Well, Husqvarna's lawn/garden tractor lineup is complex, so you can't always say it's an issue with a box store model. Gets even more messy if you start including the Sears models they made. They have about three common platforms and then the rest is all parts-bin engineering of options as to what separates a box store model from a dealer model. Seats, engines, transmissions, decks, and diffs are mixed and matched to create an insane number of models and it may vary year to year. They can make the same tractor a Chevy or a Cadillac but the fundamentals are identical.
I remember a couple years back comparing them, when the GT48 was all the rage, and the only difference between the dealer model and one at Lowes was the engine (Kawasaki on dealer model, Kohler on Lowes) and a couple hundred dollars. That is of course a significant difference and I'd prefer to have the Kawasaki myself, but the rest of the tractor was identical! I seem to remember at the time we had a big long thread about the GT48 on TBN, since the dealer model was in short supply and perceived as a special limited edition, but it was truly just an engine tweak on the same box store model Lowes had in their lineup for 2-3 years prior.
I think the more likely issue is that the YTH is probably the wrong model for your needs. They are a bit spartan.
