I purchased a new JD Gator 620 for my wife - She uses it daily with her landscaping company and around our property for various things. I did a lot of comparing and reseaching before deciding to purchase this one. First I already own a Polaris Ranger. The Ranger is faster than the Gator without a doubt, however I'm not sure who needs to drive 50 in a Gator, certainly not me. I think regardless of Gator or Ranger, it all depends on your application.
Those who like the speed and UTV racing should really consider purchasing something designed for that, which is not a Ranger or Gator. Just because it will do 50 doesn't mean its designed for the rough treatment your planning on putting it through driving 50. Nevertheless, my money is on the JD Gator for several reason, First is Safety - JD Gator is by far designed and operates safer than the Ranger - Second is Realiability, our Gator always starts regardless of weather conditions, always operates correctly and has never been in the shop for anything other than normal oil change service. You might also consider comparing the welds on a Ranger verus the Gator, you will find far superior workmanship with the JD Gator. Fit for our application, meaning it is the correct tool for our tasks. I might add that I live in Valdez, Alaska so you can imagine the weather conditions we use our Gator in. Value, I paid $11K for my Gator fully equipment from our JD dealer, try that with Ranger and you will spend $18K+. As for my Ranger, well its in the shop more than its worth, transmission and transaxle problems, bad CV's, and never ending oil leaks. What more can I say.
As for the question, "how do you like your new JD Gator XUV?"
We love it and wouldn't trade it for any other XUV on the market.
