It's a tough call man. They're all good. All the JD CUT's and SCUT's have Yanmar engines in them so they're hybrids. Kubota and Yanmar build the entire tractor from the wheels up.
Also, JD doesn't have SSQA loaders and some are not quick attach.
The new transmission in the Yanmar YT3 series is a hydro-mechanical unit that is removable and serviceable. It's more efficient than a HST.
It'd help if you could tell us more about your property and what work you want to do with the tractor. That'd help us help you weigh the options.
About 6 acres of paddock to mow and a long shared road to maintain. I have a international 2400a I use now but looking to upgrade. I would like to eventually add a backhoe. Doing landscaping leveling out low spots in fields. General small hobby farm use.
Since your current international has 46hp I'm thinking you want to stick with that amount of hp or above? Do you already own some implements?

Shelburn Falls Mass. I have about 6+acre of paddock to mow for our horses. I also have a private driveway / shared road that I help maintain. I was hoping to stay around 35k.
Within that budget you can purchase a new four cylinder Grand L or MX tractor-loader with a 6' or 7' Bush Hog, depending on how much horsepower you elect to pay for.
