I bought Dad a tracked drive snowblower in the early 90s from MTD (before I knew what MTD stood for), he didn't use it but 2 or 3 times, but every time he did, the "Guts" would fall out from under it. He would put it back together and use Loctite only for it to do it again. When I passed I brought it home and put it back together again, I used Hi-Strength Loctite. I've used it a few times now and it is staying together this time. It works pretty well, I can clear the driveway 2x faster with that 28" width than I can with the 5' blade behind my tractor and it is clearer - just don't use it if it is windy, you'll be a snowman. I have yet to see it not be able to push it's way through something. I need to pull the carb off the Tecumseh engine and clean it as it is a bit rough running - but with the electric start on it, it always starts and runs - albeit rough.
