All solid only surface rust, Came with Operators Manual, Model 450 Parts List, and Convertible 10, 10A, and 12 Service Manual.
Still has the original Onan. Not sure but I think it has the original paint, white over orange/red.Looks like it was repainted, or at least redecaled. 450s are awesome riding tractors. I've been trying for a while to talk my neighbor out of the one that sits on his property.

Does it still have the 16.5 hp twin cylinder Onan CCKA motor on the back of it?
