Lawn Mower Maintenance: Blades, Belts and Spark Plugs
Maintaining your lawn mower is essential for keeping your yard looking its best. Regular maintenance of blades, belts, and spark plugs ensures your mower runs efficiently and prolongs its lifespan. Here's a straightforward guide to help you manage these key components.
Sharpening Lawn Mower Blades
Sharp blades are crucial for a clean cut and a healthy lawn. Dull blades tear the grass, leaving it susceptible to disease. To sharpen your mower blades, follow these steps:
- Disconnect the spark plug to prevent accidental starts.
- Remove the blade by loosening the bolt that holds it in place. Use a wrench for this task.
- Secure the blade in a vice and use a metal file or a grinder to sharpen the cutting edge. Maintain the original angle of the blade.
- Balance the blade by placing it on a nail or blade balancer. If it tips to one side, file more metal from the heavier side.
- Reattach the blade, ensuring it's secure.
Regular sharpening every 20 to 25 hours of mowing is recommended. Explore our lawn mower parts and accessories for additional tools you might need.
Replacing Lawn Mower Belts
Belts transfer power from the engine to the blades. Over time, they can wear out or break, affecting performance. Here's how to replace them:
- Consult your mower's manual to locate the belt configuration and part number.
- Remove the spark plug for safety.
- Access the belt by removing the mower deck. This usually involves disengaging the deck lever and removing pins or bolts.
- Slide the belt off the pulleys, noting the path it takes.
- Install the new belt by following the same path. Ensure it's seated properly on all pulleys.
- Reattach the deck and test the mower.

Checking and Changing Spark Plugs
Spark plugs ignite the fuel-air mixture that powers the engine. A faulty spark plug can cause starting issues and poor performance. Here’s how to check and change them:
- Locate the spark plug, usually found on the side of the engine.
- Remove the spark plug wire and use a spark plug wrench to unscrew the plug.
- Inspect the plug for wear or damage. A healthy plug will have a light tan colour on the electrode.
- If replacement is needed, ensure the new plug matches the part number specified in your manual.
- Install the new plug by screwing it in by hand, then tighten with the wrench.
- Reconnect the spark plug wire.
