So,
After owning this MX5400 since this past summer/fall and getting to 50hrs, I have come to the conclusion that I really like this tractor.
I mostly have moved dirt and spread it around. I have moved snow with it as well and we had some good snow storms this year to test it. Even with the turf tires I got good traction in the snow and on the turf, except for the mud. The tractor has great power. I can lift a lot of dirt or snow at one time.
The draw backs are fuel consumption, compared to my old 25hp Ford tractor and of course the Regen.
Other than that, I am really glad I got the MX5400.
