Gas-powered lawn mowers and trimmers take their share of abuse during the warm months, so
some care at the end of the season—or at the start of spring—is vital to keeping their parts in
good working condition. Replacing the oil, spark plugs, and air filters on mowers and applying a
bit of elbow grease to grimy recesses, preferably before storing them for the winter, will ensure
that they rev up with a pull of the cord next year.
1- Empty the gas tank
Unused gas left in a mower over the winter can get stale, gumming up the carburetor and inviting
rust. First, add fuel stabilizer to the tank, then run the mower to distribute it through the system.
Turn the mower off and allow the engine to cool, then siphon excess gas into a clean can. (You
can put this gas in your car, provided it hasn’t been mixed with oil.) Restart the mower and run it
until it stops; repeat until the engine no longer starts and the fuel lines are empty.
2- Remove the spark plug
Before continuing with the remaining Lawn Care Knoxville TNmaintenance steps, it’s very
important that you disconnect the spark plug to prevent the mower from kick-starting
accidentally, which could lead to serious injury.
3- Remove the blade
To make it easier to change the oil and clean the underside of the mower, first detach the blade
by unscrewing the bolts that hold it in place. Be sure to wear thick gloves when handling the
blade. While the blade is off, take advantage of the opportunity to sharpen it
4- Drain the oil
According to the Lawn Service Knoxville TN team If the mower has a 4-cycle engine, you’ll
need to change the oil. (Some mowers and most trimmers have 2-cycle engines, in which the oil
is mixed with the gas.) Have a pan ready, and place a tarp under the mower to catch any oil that
might spatter. Set the mower on its side with the air filter and carburetor facing up, so oil and
residual gas don’t spill into them. Remove the oil reservoir plug and slowly tilt the mower until
the oil begins to drain into the pan. Replace the plug when all the oil has drained.
5- Clean the undercarriage
Use a putty knife and wire brush to scrape off the grass and mud caked on the mower
deck landscape mowing. This prevents rust, clears the passageway to the discharge chute, and
allows the aerodynamics of the deck to work as designed. With the deck cleaned, reattach the
sharpened blade. Once you’ve finished and can turn the mower upright, fill the oil tank with
fresh SAE 30 or 30-weight oil, and recycle the used oil at a service station. Don’t use a thicker
oil, such as 10W-40.
Change the air filter
A dirty air filter keeps the engine from burning gas efficiently by restricting the air needed for
combustion. If your mower has a paper filter, Lawn Care Alcoa will suggest you to replace it
with a new one, paper edges facing out. If it’s an oil-soaked sponge filter, remove it, wash it out
with soap and water, allow it to dry completely, and then add a bit of clean oil to it before putting
it back. Clear the cooling fins of dirt and debris using a screwdriver or popsicle stick.
Replace the spark plug
Remove and replace the spark plug, using a socket wrench with a spark-plug socket, which has a
neoprene lining to protect the plug’s porcelain casing. Even if the old spark plug is in good
shape, for a couple of dollars a new one will perform better and ensure a smooth start come
