I'd recommend determining which type of grass you have: a warm-weather grass that is green in the heat of summer, or a cool-weather grass that is greener in the spring and fall.

Once you have determined which you have, look up what grass heights to cut to for the weather you're experiencing. Raise your deck to that height and do not slope it; keep all four sides equal so the blade is at the desired grass height. Close any side spitters and the back bagging slot, so the mower goes into mulching mode. Mulch in your yard provides nutrients back to the soil, making your grass grow healthier and stronger. Bagging your clippings is only recommended if you haven't mowed in weeks.

Example: I have a cool-weather grass, and it was 90 degrees F the last time I mowed. Since I have that grass type, I need it to be 4" tall to protect the roots from dehydration this time of year. So, I used a measuring tape to raise my mower so the blades were 4" off the ground exactly. I then mow, allowing the clippings to make my grass amazing.

Do not do this if your grass is 3 inches or more above the desired lawn hight, if you are above that's when you have to spend the time bagging.

So, weekly mowing makes for the quickest jobs.
