Can't post a link yet, but go to Tractorhouse and search for the gc1723e - no gc1725m pictures out there yet that I can find.
This is the first one of the new series I've seen, and I've been looking for a couple weeks now. Looks like new hood, new headlights, fender joystick, tilt steering, new dash, covered toolbox, and a full-width rubber floor mat. That's at least all that I noticed. Sounds like the drivetrain remains unchanged.
