Yep, the Hydraulic PTO on that thing is worth $300 in parts, the wheel weights are worth $75 to $100 each. The Case tractors are TANKs.
That tractor has been modified, there is an electric clutch on the front of the engine that is used to drive the mower and or snowblower. I don't recall if there was an optional conversion kit for that or not. You'll need to ask the Guru's over at https://casecoltingersoll.com
Bill at Barneveld Implement could answer that kind of question.
If you do snag it, my suggestion based on what I am finding in a 'Barn find' I am working, on, and I know the 1st thing you will want to do is see if the engine runs, but you need to pull the heads and valve covers off that thing and make sure things are not rusted up. Main problem is that the rust WILL rub off the valve stems and cylinder walls, and act like sand paper in the engine. THe Onan B43 engine in that guy does not have an oil filter on it. the process is fairly simple its, basically the process Onan Calls Decarboning the engine.. But with it setting on a dirt floor there could be ALOT of moisture in and on that tractor.. I wonder what the underside of that mower deck looks like??
Also if you want to see more of what that tractor looks like torn down, my Buddy Lionel on the Case forum does an insane job of restoring tractors and documenting the process with pictures, there is a thread: https://casecoltingersoll.com/showth...ct-another-446
where he did a 2 tone 446 similar to this one, in those pictures he'll get it all of the way down to the frame.
