How to service a lawn mower
Regular maintenance of your lawn mower is essential for its longevity and efficiency. A well-serviced lawn mower will not only help you achieve a pristine-looking lawn, but it will also save you money on costly repairs and replacements. Whether you have a push mower, a riding mower, or a self-propelled mower, taking the time to service it will ensure that it runs smoothly and efficiently.
When it comes to servicing your lawn mower, there are a few key tasks that you should focus on. These tasks include changing the oil, replacing the spark plug, cleaning or replacing the air filter, sharpening the blades, and lubricating moving parts. By performing these routine maintenance tasks, you can ensure that your lawn mower is in top condition and ready to tackle any mowing job.
One of the first tasks you should tackle is changing the oil in your lawn mower. Over time, the oil can become dirty and lose its effectiveness, which can lead to engine damage. By changing the oil regularly, you can extend the life of your lawn mower and keep it running smoothly. To change the oil, first, make sure the engine is cool, then drain the old oil by removing the drain plug and allowing it to drain completely. Once the old oil has been drained, replace the plug and fill the engine with fresh, high-quality oil.
Common Lawn Mower Issues
Unfortunately, like any mechanical device, lawn mowers can experience a variety of issues. Here are some of the most common problems you may encounter with your lawn mower:

Replacing Lawn Mower Blades
Proper maintenance and replacement of lawn mower blades are essential for maintaining a healthy and well-manicured lawn. Over time, the blades on your lawn mower can become dull or damaged, affecting the quality of your cut. Follow these steps to replace the blades on your lawn mower:
1. Safety First
Before starting the process, ensure that the lawn mower is turned off and disconnect the spark plug. This will prevent any accidental start-ups during the blade replacement. It is also advisable to wear gloves and safety glasses to protect yourself from any sharp edges or debris.

Carefully align the new blade on the mower’s spindle, making sure it is correctly oriented and positioned. Replace the bolt or nut and use the socket wrench to securely tighten it. Ensure that the blade is centered and properly balanced to prevent any vibration or damage to the mower.
Note: It is important to refer to the lawn mower’s manual or manufacturer’s guidelines for the appropriate torque specifications when tightening the blade.
4. Test and Adjust
Once the new blade is installed, lower the mower to its normal operating position. Reconnect the spark plug and start the mower to test the blade installation. Take note of any unusual vibrations or noises, as these could be an indication of an improperly installed blade. If necessary, readjust the blade to ensure smooth and efficient operation.
Regularly inspecting and replacing your lawn mower blades will ensure optimal cutting performance and keep your lawn looking its best.

Lawn Mower Oil Change
Regularly changing the oil in your lawn mower is essential to keep it running smoothly and prolong its lifespan. Here’s a step-by-step guide on how to perform an oil change on your lawn mower:
Gather the necessary materials
Before beginning the oil change, make sure you have the following materials:
- New oil
- An oil pan
- An adjustable wrench
- A clean rag
Find the drain plug
Locate the oil drain plug underneath the mower. It is usually located on the bottom side of the engine.
Note: Consult your lawn mower’s manual to find the exact location of the oil drain plug as it may vary depending on the model.
Drain the old oil
Place the oil pan underneath the drain plug. Use the adjustable wrench to loosen the plug counterclockwise until oil starts to flow. Allow all the old oil to drain completely into the pan.
Replace the oil filter (if applicable)
If your lawn mower has an oil filter, it’s wise to replace it at the same time as the oil change. Unscrew the old filter using an oil filter wrench and install a new one, making sure it is tightened securely.
Fill with fresh oil
After the old oil has been drained, wipe the drain plug with a clean rag and screw it back into place. Refer to your lawn mower’s manual to determine the appropriate type and amount of new oil to use. Slowly pour the new oil into the oil fill port, making sure not to overfill.
Check the oil level
Once you’ve filled the mower with new oil, let it settle for a few minutes. Then, remove the dipstick, wipe it clean, and reinsert it. Take it out again and check the oil level. It should be within the recommended range on the dipstick.
Performing regular oil changes will help keep your lawn mower running smoothly and extend its overall lifespan. Make sure to dispose of the old oil properly according to your local regulations.
Storing and Winterizing Lawn Mower
Properly storing and winterizing your lawn mower is crucial to ensure its longevity and efficiency. Follow these steps to prepare your lawn mower for the winter months.
1. Clean the Lawn Mower
Before storing your lawn mower, it is important to clean it thoroughly. Remove any grass, dirt, or debris that may have accumulated on the mower deck or undercarriage. Use a brush or a scraper to help loosen any stuck-on debris. Cleaning the mower will prevent rust and corrosion, prolonging its lifespan.
2. Drain the Fuel
Next, drain the fuel tank and carburetor to prevent any stale fuel from gumming up the engine. Run the lawn mower until it runs out of fuel or use a siphon pump to remove the fuel from the tank. It is recommended to add a fuel stabilizer to the remaining fuel before running the engine, as it will help prevent ethanol-based fuel from deteriorating and causing damage.
3. Change the Oil
Before storing your lawn mower for the winter, it is recommended to change the oil. This will help remove any contaminants and ensure fresh oil for the next mowing season. Refer to your lawn mower’s manual for the specific type of oil and the proper procedure for changing it.
4. Remove the Battery
If your lawn mower has a battery, it is important to remove it for the winter. Store the battery in a cool and dry location, away from any flammable materials. Keeping the battery in optimal condition will help ensure an easy start in the spring.
5. Store Indoors
For the best protection against the elements, store your lawn mower indoors, such as in a garage or shed. If indoor storage is not possible, use a weatherproof cover to protect it from rain, snow, and cold temperatures. Consider placing a board or a piece of wood under the wheels to prevent flat spots.
By following these steps, you can ensure that your lawn mower is stored and winterized properly. This will not only help keep your equipment in good condition but also make sure it is ready for the next mowing season without any issues.
