The cool thing here is that the '45 with the stripped gears was my wife's dad's tractor, and the '42 belonged to her uncle (her mother's brother) who lived on a nearby farm. It is possible that during their working lives these tractors occasionally worked side by side. It would be very fitting if we could use some parts, any parts, from the '42 to help fix the '45.
I said cultivator then got to wondering because they didn't look like any mounts I had ever seen. Not that I have seen many but thinking maybe buzz saw or something. Got to looking at google images and found these on an M. A lot of cultivators were made to fit both the H and M. Having said that, that is a lot for an H, most were two rows. Might be good for parade duty to keep the kids back, but I think it would make an H grunt when you dropped them in the ground. Don't know which model cultivator they are but at least now you can identify what they look like should you ever want a set. More than likely they'll find you!
I bet both tractors did work together more than once. Definitely need to use some parts.
