lawn tractor suddenly started blowing out Alot of thick white smoke

i have a b&s 8hp engine mounted on an old john deere(mower deck not attached). i was driving it through the forest beside my house, running it pretty hard, then all of a sudden a TON of thick white smoke started pouring out of the exhaust and smoked out the whole forest. i havnt tried to start it since. and the oil is not overfilled.

any suggestions? thanks

Did it make a lot of noise when it started with the smoke? If it clattered the engine needs torn down. If not........

Try to start it and let it run for a while, even if it smokes a lot. If you run it for more than five minutes and the smoke isn't clearing up, top it and check the oil to make sure it's staying up where it should be.

I suspect you hit a bump and slopped oil up against the piston and it went past the rings.

It could be more serious, like a blown ring/piston, but do the above first.
