Small Engines (Lawn Mowers, etc.): drain oils bolt, drain oil, dipstick

Question
where is location drain oil bolt for craftsman 6.75 hp? thank you.

Answer
It is on the bottom of the engine.  It may be eaiser to invest in a drill motor oil changing pump.  They cost less than $15.00 and makes changing the oil much eaiser.  Just warm up the engine by running it a few minutes, shut it off, remove the dipstick and insert the hose from the oil changing pump.  Start the drill and pump out the old oil.
What is the model number of your mower?
Let me know.
