Hi everyone, new to the forum. I recently purchased a 1977 446 repowered with an 18 hp b&s vanguard. It came with a mower deck, rototiller, and L84 snowcaster. I'm currently trying to replace the bearings in the snowcaster and cannot for the life of me remove the jackshaft. I've read elsewhere that most people end up cutting and replacing the shaft with all new materials. Just wondering if anyone has a good source for OEM or aftermarket snowcaster parts? Thank you!
