Depends on the model but all you have to do is pull off the cowling to get to the flywheel nut. Then feed rope down the spark plug hole or jam the blade bar with a block of wood to stop the engine turning over whilst you loosen the nut. The other way you can remove the nut is by using a rattle gun but make sure it's in reverse!
There should be threaded holes in the flywheel to attach the Briggs & Stratton style puller. I haven't had much to do with the modern DOV engine so I'm not sure if there are any differences to the older ones.
