A used lawn mower can be an excellent investment for those who want to maintain a beautiful and healthy lawn without breaking the bank. However, just like any other piece of machinery, a used mower requires regular maintenance to ensure optimal performance and longevity. In this guide, we will cover the essential maintenance tips for a used lawn mower, from cleaning and oiling to blade sharpening and air filter replacement.
Cleaning the Mower
The first step to maintaining a used lawn mower is to clean it thoroughly after each use. This involves removing any debris, grass clippings, and other materials from the blades, undercarriage, and the air filter. Use a wire brush or putty knife to scrape off the buildup and a damp cloth or hose to wash away any remaining residue.
Checking and Changing the Oil
Oil is the lifeblood of a lawn mower’s engine, and it needs to be checked and changed regularly. Consult your owner’s manual for the recommended frequency and procedure. In general, you should check the oil level before each use and change the oil every 50 hours of operation or once a year, whichever comes first. To change the oil, drain the old oil, replace the oil filter, and refill with new oil of the recommended type and amount.
Sharpening the Blades
A dull blade can damage your lawn, as it tears and bruises the grass instead of cutting it cleanly. Therefore, you should sharpen the mower blades regularly, ideally after every 25 hours of use. You can do it yourself with a sharpening stone or a file, or take it to a professional sharpening service. Make sure to balance the blade after sharpening to prevent vibration and uneven cutting.
Replacing the Air Filter
The air filter of a lawn mower prevents dirt, dust, and debris from entering the engine and causing damage. However, it can become clogged over time and restrict the airflow, which reduces the engine’s power and efficiency. You should check the air filter at least once a season and replace it if it is dirty or damaged. To do so, remove the air filter cover, take out the old filter, and install a new one of the same type and size.
Inspecting the Spark Plug
The spark plug of a lawn mower ignites the fuel and air mixture in the engine, which powers the mower’s movement and cutting. A worn or fouled spark plug can cause hard starting, misfiring, and reduced performance. You should inspect the spark plug at least once a season and replace it if it is dirty, corroded, or has a damaged electrode. To replace the spark plug, disconnect the spark plug wire, remove the old plug with a socket wrench, and install a new one of the same type and gap.
Checking the Belts and Pulleys
The belts and pulleys of a lawn mower transmit power from the engine to the blades and wheels. They can wear out or become loose over time, which reduces the cutting and driving performance. You should check the belts and pulleys regularly and replace them if they are frayed, cracked, or stretched. To do so, consult your owner’s manual for the specific procedure and parts.
Storing the Mower
Proper storage is crucial for the long-term health and safety of your used lawn mower. Before storing the mower for the off-season or a prolonged period, you should drain the fuel tank or add a fuel stabilizer, remove the battery or keep it charged, cover the mower with a tarp or a specialized cover, and keep it in a dry and cool place. Additionally, you should prepare the mower for the next season by checking the oil level, inspecting the blades, and performing any necessary maintenance or repairs.
Other Tips and Considerations
Aside from the essential maintenance tasks, there are other tips and considerations to keep in mind when maintaining a used lawn mower. For example, you should always wear protective gear such as gloves, eye and ear protection, and closed-toe shoes when operating or working on the mower. You should also follow the manufacturer’s instructions and warnings, such as not tipping the mower on its side or using it on steep slopes.
Conclusion:
Maintaining a used lawn mower may seem like a daunting task, but it is essential for keeping your lawn healthy and your investment worthwhile. By following the steps and tips in this guide, you can ensure that your mower operates at its best and lasts for years to come. Remember to clean the mower, check and change the oil, sharpen the blades, replace the air filter, inspect the spark plug, check the belts and pulleys, store the mower properly, and follow the safety precautions. Happy mowing!
