is it a good idea to lock a rear diff on my new craftsman lt 1000

hello i have a few questions has any body locked a rear diff on a lt 1000 and is it a wise idea and what would i need to do to do this i have been building these mowers for years now and was a bit scared on locking diffs and need some advice and how would i make a gas petal on it it has a 11hp b&s on her lol

Ya I've done it before I would use a piece of pipe and lock it that way

You could weld the spider gears (2) to the big main pin, fearless have a video on it. If you google a fozzy lock gears for like a mst205 that's another way.
