Lawn Mower Tune-Up Guide: Parts You Should Replace Before Mowing Season

Lawn Mower Tune-Up Guide: Parts You Should Replace Before Mowing Season

As the weather warms up and grass starts growing, it’s time to get your lawn mower ready for the season ahead. A well-maintained mower not only ensures a clean, even cut but also extends the life of your machine. Performing a tune-up before the first mow of the season can prevent breakdowns and keep your mower running smoothly all summer long.

To help you get started, here’s a list of essential replacement parts to check and swap out before you fire up your mower this spring.

1. Blades

Sharp blades are essential for a clean cut. Dull or damaged blades tear the grass instead of slicing it, leading to an unhealthy lawn. If your blades are nicked, worn down, or bent, it’s time to replace them. For optimal performance, consider keeping a spare set on hand so you can swap them out mid-season if needed.

2. Spark Plugs

A faulty spark plug can make your mower difficult to start and cause it to run inefficiently. Replacing the spark plug is a quick and inexpensive fix that improves fuel combustion and engine performance. If your mower has been sitting idle all winter, installing a fresh spark plug can make all the difference.

3. Air and Fuel Filters

  • Air Filter: A clogged air filter restricts airflow to the engine, reducing power and efficiency. Replacing it ensures your engine gets the clean air it needs to run smoothly.

  • Fuel Filter: If your mower has a fuel filter, check it for blockages. A dirty fuel filter can prevent fuel from reaching the engine properly, leading to performance issues or stalling.

4. Oil and Oil Filter

Just like in a car, fresh oil keeps your mower’s engine lubricated and running efficiently. Old, dirty oil can cause excessive wear on engine components. Drain the old oil and replace it with the manufacturer-recommended type, and if your mower has an oil filter, replace that as well.

5. Drive and Deck Belts

Belts play a crucial role in transferring power from the engine to the cutting deck or drive system. Over time, belts can wear out, crack, or stretch, reducing performance. Inspect them for any signs of damage and replace them if necessary to keep your mower operating efficiently.

6. Battery (For Riding Mowers)

If you have a riding mower, the battery may have lost charge over the winter. Test it before the season starts, and if it’s struggling to hold a charge, consider replacing it to avoid downtime.

7. Fuel System Check

Old fuel can cause engine problems, so if you left gas in the tank over winter, drain it and refill with fresh fuel. Consider using a fuel stabilizer in the future to prevent issues with stale gas.

8. Tires (For Riding Mowers)

Check the air pressure in your riding mower’s tires. Underinflated tires can affect traction and maneuverability, making mowing more difficult. Look for cracks or signs of dry rot and replace any damaged tires.
