Step 1 Tune Your Mower
Change the oil, air filter and spark plug. Clean the top and undercarriage, removing dirt and grass clippings - be sure to detach the spark plug wire before working around the cutting blade. Don’t flip a gas mower over to clean underneath; simply lift one side and brush away dried grass. Sharpen the mower blade, and replace it if it has large nicks or gouges. It’s a good idea to keep an extra blade on hand so you always cut with a sharp edge. If you prefer a hands-off approach, take your mower to the shop, though you may want to do it in late fall or winter to avoid spring crowds. Last but not least, fill the fuel tank. Note, a cold mower can be hard to start in early spring. Warm it up by placing it in the sun for an hour or two prior to starting.
