Lawn mowers make quick work of mowing your lawn. During an average summer, you'll use your lawn mower twenty hours or more, depending on the size of your yard and the climate you live in. Whether your lawn mower is gas powered or electric, service it every spring for years of reliable use. Most mowers need regular cleaning and lubricating. Sharpen the blade at least once every season. Lubricate the wheel gears if required at least once per season, and replace wheels when they become worn. Store your lawn mower in a dry shed when not in use.
Turn off the mower and allow the blade to stop spinning before attempting to remove the wheel.
Turn the lawn mower on its side on a flat, level surface.
Slide the screwdriver under the cap covering the bolt (if the tire has one) and carefully pop it off.
Loosen the nut on the inside of the tire by turning it in a counterclockwise motion with the crescent or box wrench. Remove the nut and put it in your pocket for safekeeping.
Slide the bolt off the axle and put it in your pocket as well. Slide the tire off the axle and set it aside.
Replace the tire on the axle. Reassemble by sliding the bolt through the wheel. Place the nut on the bolt on the interior side of the tire and tighten with a crescent or box wrench.
Turn the lawn mower over to the other side to access the other wheels if necessary.
