I compared the Deere x380 to the Husky GT48DXLS. The Deere deck is thicker (10ga vs 11 ga,) which doesn't help me when mowing. At least I don't think so. My mowing needs are simple, about a half acre, mostly flat although one area I am now mowing where my old Craftsman would not. That's because the Husky has an electric locking differential, and more power, which the Craftsman didn't have. Someone else here just evaluated many models and bought a Deere x380 and really likes it. That's understandable, as they are both fine machines.
My pricing for a Deere x380 was more than 50% more than a Husky, at about $4,500 for the Deere and $3k for the Husky. And the Husky does have the locking differential. Deere obviously knows the engineering of a locking differential. It's my opinion Deere purposely withholds that from the x3XX platform to encourage buyers ($$) into the x5XX platform instead. Considering how similar the specs are between these two models, and that Deere is 50% priced higher, I would not be surprised if there is a future price cut on the x380.
If you scroll down on the list of forums to the general Lawn and Garden, click on Husky, then the thread about this new model. You can see a picture of mine there. They do exist!
