Yep. Yep. Had power wheel drive failures too since I was ~12 y.o. back in the last millennia.
I ain't that grunting 12 to 30 y.o. anymore.
Wised up and watched yardsales, curbside thrwoaways for really light weight decks with ballbearing wheels and bad motors.
I've remounted my good motors and pushed-on much easier for years.
Current, oldest Honda engine now on it's second deck install. The stamped steel lightweight decks will "tin-can" crack at the wheels stressed mounting corners sooner-or-later. Only worth plating a couple of times - stress cracking just move out past the reinforcement.
This last install has that long shaft power drive engine stand-up mounted onto long 12mm diameter bolts sitting on nutted stacks to get the right blade height.
Leaves a big gap between the engine bottom and deck top.
Ha! Center-air sucked IN, it blows out below, and cut grass clears much better. Engine with better surround air flow runs cooler, too.
And I do have an old, old 1950's magnesium deck squirreled away. Be great for "perfect" yards. Here surfaces small stones from the moles would fling out holing it with created metallic shrapnel.
