Way cool!! I had the same Case 450 high lift dozer when I was digging my lake, except I didn't have the "cool" bucket. Also, when hauling it once, I did get a "nice" warning by a D.O.T. cop. He allowed me to get off without any tickets if I called someone to come pickup my dozer with the proper equipment. i.e., he wouldn't let me move it from where he had stopped me.
I was towing it with a 1996 1/2 ton Chevy 4X4 with the 6.5 diesel. Yes, 1/2 ton! Apparently many people don't remember that you could get that in 1996. Anyway, I far exceeded not only my towing capabilities, by truck plate weight, my trailer weight, my trailer plate weight, but also numerous other "securing" violations.

I was actually running in 4X4 low range through the city.
Oh well, you have one nice little dozer though!! I can rebuild your steering brakes, repack your lift cylinders, and change the hoses to the hydro pump (right on front of the engine) in my sleep! Make sure you keep the tracks at the correct tension. I killed 2 idlers; one because I had the tracks too tight, and another because I had too much slop in the tracks. I'm still amazed what a grease gun will move!!
