What is this part and what is it used for?
 

Please help me identify what this part is and is used for! It mounts on the rear of an IH built tractor cast iron rear end and extends it out. Once I was told it was part of a bagger system? I have no use for it and l would like to find out what it is to possibly help someone out in need of it!

I don't know Dave, but it looks homemade to me.

The lower left-hand and upper right hand pictures looks like a partial aluminum rear drawbar bolt pattern??
Forwhatever reason.

I thought homemade also, pretty sturdy looking, maybe a weight box??

I have an EZ book. It may be a 642 hitch. It may be the one used if you have a 3 point hitch and tiller gearbox attached.
