Riding Mower Engine Locked Up

I was cutting grass on my rider, and it just went "pow", now the engine is locked, I can't even turn it by hand. The starter works fine, and there is oil in the engine, there is no oil leaking, what is wrong?

My husband says the problem could be a wrist pin, a broken valve or a blown rod. Without seeing it, he feels more strongly about the wrist pin.

It may sound silly, but have you checked underneath to see if anything is lodged and keeping the blade from moving? Mine did the same thing and when I tipped it up I found a big rock in there keeping the blades from moving at all. I knocked the rock out with a hammer and it started right up!
