I'm not sure what parts interchange either, and at this point in time I don't even know what, if anything, will need repacing on the baler itself.
We're focusing on the engine right now.
The rest of the baler is pretty solid. I've cycled it a few times by hand and everything's moving properly. I have no idea if the knotters are going to work - that's my biggest concern until I see them knot. Everything looks to be there, but I'm not exactly a new holland expert.
So no list of needs yet. We'll be digging into it deeper over the next couple of weeks.
