kohler courage question

[randyeicher]

The kohler courage 19 sv590 on my Troy-bilt died today with cracked block. I found a good deal on a used kohler courage 20 sv600. Will it directly replace my courage 19?

Need to confirm that crankshaft length and diameter are the same, but other than that I don't see a reason why it wouldn't be plug and play.
