I think the problem comes in when owners of the GT48DXLS try to compare their tractor to a X380/390 or even a X590- Trust me the build quality isn’t even close. I get your dealer didn’t even stock any so I don’t blame you. Well I’m not going to bad mouth your new tractor. Suffice to say we can agree to disagree on build quality. Good luck!!
I don't know what you disagree on build quality about - maybe Deere has slipped in their build quality. Are they not assembling parts correctly? Cross-threading bolts? Leaving off the armrests? Not installing the front brushguard? I don't know, having not seen a new Deere above the L1xx in person.
I can attest to the build quality of my GT48DXLS. I've been over and under the machine, and ridden it hard on challenging terrain, and it's perfect. Every fastener was installed properly, deck was adjusted perfectly, and it all works perfectly. The dealer did an excellent job prepping it, so I had no issues at all when it was delivered to me. Kawasaki and TuffTorq seem to have held up their end of the deal, as well.
I'm not bad mouthing Deere's build quality - I believe that I could buy a x590 sight unseen and have a fine machine delivered. I believe it to be a slightly superior machine to what I bought, but what I bought exceeds all my expectations and certainly meets my needs exceptionally well. The x590 would do so, too. The x380/390, assembled to perfection, would not - the lack of a locking differential in my application makes it the wrong tool for the job. It's like comparing a Porsche 911 to a Ford F-350 - Porsche is far superior, until you need to tow a 28' gooseneck stock trailer.
I admire John Deere as a company. They have worked long and hard to build their brand, and have used their reputation and brand recognition to expand their market. They have built a parts network that is second to none. They have a huge, intensively loyal customer base. Those customers are offered a huge variety of products to spend vast amounts of money buying. The brand carries a premium price, and the company remains profitable. If my local dealer provided the quality of customer service in the consumer lawn and garden section or the small tractor arena that they do in the Ag tractor area, I'd probably own a green tractor and a green mower today, and be about $20k lighter in the bank account.
I'm not claiming Husqvarna to be superior to John Deere in any way except in my specific case. The particular model I purchased meets my needs in every way, and exceeds them in some. NONE of the other Husqvarna models do that. There are many, many mowers on the market that do not meet my needs, and only a very few that do. Of those, only the Deere x590 and the Husqvarna GT48DXLS have local dealers, and that mattered to me.
If I had to make the decision again today, I'd be unhappy. I believe the supply of GT48DXLS models is likely exhausted - they were a limited run this year, and many others recognized the value. Maybe they will be a regular production unit next year, maybe not. I'm glad I got mine!
