Me? I would disconnect the throttle linkage at the carb and start it again.
Then inspect the linkage to see if it went into a full throttle position due to a broken governor or if it was just put together wrong.
Shut off the tractor and repair as needed.
If the tractor still goes full throttle with the linkage disconnected, stuck throttle butterfly, or missing?
Then again, others with far more knowledge and experience should be along shortly.
