Well, i have found-the best way to mower the lawn is to first buy a nice self-propelled walk behind lawn mower. Read the instructions on how to sstart it, and how to maintain it, and after you discover the proper way to do those things--start it up and go mow the lawn. If you need instructions on that--ride around until you see somebody mowing their lawn, and watch to see how it is done!
The main thing in lawn mowing is this sequence of operation:
Clear lawn of all rocks, dog bones and deposits, sticks and other detritus. Start engine. Push mower in straight overlapping lines, then mow around trees, plantings, etc. When you get tired or when you are finished, shut it down, push it out back and into the garage, then open a cool one, and sit back and admire your handiwork!
If you buy a power mower, the blade that comes with it will usually suffice for regular lawn mowing. If you have special needs, check where you bought the mower. They might have special blades.
Warning: Keep hands and feet out from under a running rotary or any kind of powered mower when it is running! If you buy a new one, before starting it--read fully the manual that comes with it, so you don't find your fingers laying on the floor, or the grass!
Also, most new lawn equipment comes with no oil in the engine, so check that first before starting it! And, always check the oil before starting, the next time you go to use it! Wipe the stick, then insert it again to get the true reading.
Be careful with any powered equipment, and you shouldn't have any problems.

I use a kaiser blade, some folks calls it a sling blade, I call it a kaiser blade. It's just a long handle like a axe handle with a long blade on it that's shaped kind of like a banana. Sharp on one edge and dull on the other. It's what the highway boys use to cut down weeds and whatnot.

This is a joke right? OK I'll bit too! you must live in the desert, if so, I would have one of the pet rock lawns and garden in Neveda or maybe a catus gardens. You will save on water, lawn equipment, time mowing the lawn, and have more money for those long hot days and nights to drink the suds as suggested without all the work or to waste on the craps table. Green grass not suspose to be if you live in the desert area..
