Solid Model of JD 4500

[MMH]

I want to design & build a fairly involved implement for my JD. I would like to start by getting a solid model of my JD4500. I guess that any JD4000 series would be close enough. I guess it does not even have to be a JD, but I would feel better if it were. In particular, I would want good detail on the 3pt. lift & PTO.

Any suggestions on where to look? BTW, I am using SolidWorks which is fairly common 3D modelling software.
