How to Tune Up Your John Deere Lawn Mower

How to Tune Up Your John Deere Lawn Mower

Excited to start up your John Deere lawn mower but want to make sure it’s in peak condition before taking on your yard? We’re here to get you started! Use our checklist below to tune up your John Deere Lawn Mower and make sure it performs exceptionally all season long.

1. Tune Up Your John Deere Lawn Mower: Drain Old Fuel and Change the Oil

Typically, fuel should be drained from your John Deere lawn mower before putting it into winter storage each year, but if there is any leftover fuel from last season left in the tank, make sure you drain it now. Because old fuel can separate into deposits and clog the carburetor, it is possible that you will discover some damage as you inspect your mower (if you find that any parts have been damaged, you can search for replacement parts here). Next, change the oil to help ensure engine longevity and better performance.

2. Tune Up Your John Deere Lawn Mower: Clean or Replace the Air Filter

Depending on what type of air filter you have, you can boost performance by cleaning or replacing the filter. Foam filters can be washed with hot water and dish soap, while paper filters should be replaced once they are no longer usable. To determine if your paper filter is in working condition, remove it from your mower, tap off excess dust, and hold it up to a bright light. If the light shines through the filter, it is clean enough to put back on your mower. If you cannot see any light, the filter is dirty and should be replaced.

3.  Tune Up Your John Deere Lawn Mower: Change the Spark Plug

Ideally, spark plugs should be replaced each year or after 100 hours of use, whichever comes first. Although spark plugs rarely go bad, they are good indicators of underlying engine problems and as a result should always be taken care of. Use a crescent wrench or pair of vise grips to turn the metal base and remove the spark plug, then place a few drops of oil into the open cylinder. Start the engine a few times to coat inside valves, then replace your old spark plug with a new one. Remember to use the same part number, as there are many types of spark plugs available as you work with different equipment (click here to find spark plugs).

4. Tune Up Your John Deere Lawn Mower: Sharpen Blades

Sharp blades can make a huge difference in cut quality. Check blades for excessive dents, chips, or wearing that could have an impact on mowing performance, and sharpen or replace depending on severity of damage.

5. Tune Up Your John Deere Lawn Mower: Double-Check Bolts, Wheels, Cables, and Belts

Finally, inspect your John Deere for any loose bolts, worn cables or belts, or damaged wheels. Tighten, repair, and replace as needed to help avoid future problems that could pop up later in the mowing season (click here to find parts by illustrated diagram).
