Back when the 11528 and my 926LE were "new", there were plenty of posts by snowmann (I think his real name was Paul?) talking about how Ariens did NOT make models different for HD than for dealers. There were some dealer exclusive models (as there still are), but a 926LE, 11528LE, etc at Home Depot were exactly the same as at a dealer. And if you think about it, why would anyone want to spend money on a production line to make something "just a bit different" depending on its destination location?
NOW, yes, you can buy the black Sno-Tek models and they are definitely watered down compared to the "real" orange colored Ariens models. But it sure looks like a Deluxe 30 from HD is the same as a Deluxe 30 from a dealer. Obviously your support network is better from a small dealer (or, not, depending on your dealer) but machine wise I still think they are apples to apples if the model is the same.
What I find interesting is my local Lowes....all the John Deere blowers they've had in the past have dealer stickers right on them. Seems like they are all assembled and setup by a local dealer before being for sale at Lowes. I think thats changed (not even sure they carry JD anymore?) but its interesting that I could have gotten a "dealer" prepped John Deere from Lowes.
