For those just tuning in last time I tried to run this thing all the old lower belts came apart. They got stuck in the chamber of the baler which made the baler thing it had a bale so it actually did its little dance where it shuts off the feed chain, dropped the twine arm and slowly pulled it back up (I didn't have twine in it) and then ejected the wad of belts out the back.
I have since accumulated a few new belts. And I think thanks to the parts baler I have enough belting to patch together a complete lower set. Last night I harvested three lower belts off the parts unit and one upper, I also snagged a used upper belt from my uncle which I think will get me enough to try again.
