Apparently is is worth over $1,000 to have quick change adjustment to mower deck wheels that most of us seldom touch.
I appreciate the attempt at humor, but when I was shopping last year, the X380 ended up costing a mere $300 over the then-best Husky GT52XLS. For that $300 I saw a lot of nice touches and advantages on the Deere beyond those deck wheels (which you would adjust if you had dramatically different cutting heights to accommodate, as I do):
* Stouter frame and rear hitch area. I have long lamented that modern yard tractors are cheesily built compared to decades ago, so this matters to me and was a big bonus for Deere.
* Much nicer seat on the Deere -- night and day difference
* Deere has a an LCD instrument panel with diagnostics/etc
* cruise control easier to operate (button on dash versus lever on Husky)
* Deere has an actual electronic fuel gauge on dash (Husky has view window on the tank to see fuel level through translucent tank wall)
* Dial adjust for deck height with 1/4" resolution (retains position when deck raised to stow position)
* At the time, Deere Accel Deep deck was far superior in every way
* Deere deck much easier to remove/attach and can roll out from under tractor sideways (i.e., the deck wheels turn 90deg)
* on-the-fly mulch control door to easily switch mowing modes
* 4-year/300-hour warranty on Deere versus 3-year on Husky
* lower/wider rear footprint on Deere
Some of that stuff falls into the "nice to have" category, but other stuff absolutely costs more money and I think you get what you pay for. For $300 it was a no brainer. Even for $1000 you are getting value, if that stuff matters to you. Overall, I just got the impression that whoever designed the Deere made an effort to add valuable features and nice touches all the way around with this new 2016 model.
What was better about the Husky GT52:
*included a front brush guard versus Deere's minimal (though stouter) bumper
*included armrests on seat
*slightly larger diameter tires (may be a + or -)
Differences to the 2017 GT48:
* GT48 has a diff lock not on GT52 or X380
* GT48 (and YT42, YT48) has better deck than GT52 which is much closer to Deere for cut quality/performance
Overall, I got the impression that this is the same Husky design that has been around since 2013, underpinning the Husky GT and Sears Pro GT models, with different configuration and better deck. The GT48 is among the best optioned Husky model when you look at the engine, transmission/diff, and deck its configured with.
