Riding lawn mowers

I see too many single cylinder Kohler Courage engines in the junkyard. I think they came close to a class action lawsuit on that one. I have an otherwise good zero turn with a Command twin with a broken connecting rod. Got to get that fixed to cut my mowing time to a third or less.
What kind of mower? (Brand, size of deck)
Horizontal or vertical shaft? What HP is on it now?
Where a bouts are you located?
Never know what someone else here, might have just laying around in the shed to get you going....
