There should be a drain plug on the underside of the mower deck. Raise that side of deck, remove the plug and drain the oil. Replace the plug and add new oil. Hope this helped.

SOURCE: how much oil to put in a 6.25 briggs and stratten

They hold APPROXIMATELY 20 ounces. Put in around 18 oz and start checking the dipstick and adding a little until it gets to the full or MAX or whatever it says on your particular engines stick. Each time you ad a little, give it a chance to drain down or you will get a false reading

Hi JustSomeDude...

Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
NOTE: Before you dissemble the carburetor:
Make sure you mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you dissemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Also check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one.
Also make sure you are using fresh fuel
If the mower is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank and run for short periods of time.
I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
Once you have your carburetor rebuilt that should solve your problem.

Cannot find drain to change oil.

Poulon 550 yellow 22" Briggs and Stratton. It looks like you have to drain it out the cap by tipping it. There IS no plug on mine - spent 40 minutes looking for one, and I know what both types of the plug look like. What a lousy design. This mower is a piece of junk. The valve froze a week after I got it. Never again. A headache.

What kind of oil does the 22 hp briggs stratton take

from briggs site:
For optimum performance, you should change the oil in your small engine after the first five hours of use and then annually, or every 50 hours of use (whichever comes first).
  • Use Briggs & Stratton SAE 30W Oil above 40°F (4°C) for all of our engines.
  • Check oil level regularly.
  • Air-cooled engines burn about an ounce of oil per cylinder, per hour.
  • Fill to mark on dipstick. DO NOT OVERFILL.
