This would match what I heard about the Horicon products changing from LT through X series. Doesn't look like major changes. I took a look at the online Deere parts website, and found the X748 seems to be a diesel, and it seems to have 4 wheel drive. There is also a X744 model, and that appears to be a diesel, 2 wheel drive, 4 wheel steer. The X740 is the diesel, 2 wheel drive, 2 wheel steer. Looks like the models match up like this:
X475 2ws - X700
X485 2ws - X720
X485 4ws - X724
X585 4wd - X728
X495 2ws - X740
X495 4ws - X744
X595 4wd - X748
I wonder what they will look like. I hear they have a new hood that looks like the larger 8030 series AG tractors. Dutch445, have you heard anything yet?
