Thanks, guys. It was a long but fairly easy project.
@Frank. That "winch" at the rear is much more than just a winch. It would also be used to power accessories by a belt drive. Things like a saw mill for example. A couple of my uncles back in northern Minnesota had tractors with similar rigs attached and I remember seeing them in operation with a large belt attached to the tractor and the machine that it was to provide power to through the belt drive. Back in the day before OSHA and other agencies there were a lot of farm accidents caused by those belt drives and people getting snatched up in the belt or the belt breaking and flaying anyone in the vicinity.
I couldn't figure out what the two attachments were for, especially the lower one (I printed both). I guess that the upper one (that looks like a car wheel rim) is for a belt drive and the lower one one is used for pulling? Both definitely look like the had the potential for free field amputations.
