Maintenance Tips for Residential and Commercial Lawnmowers

by | Jul 11, 2024

Hey everyone! If you want your lawn mower to last for years, you need to give it a little TLC. Whether you’re mowing your own lawn or running a landscaping business here in Bethel, these tips will help you get the most out of your mower. Let’s dive into some straightforward tips to keep your mower running smoothly.

Keeping It Clean

Daily Cleaning: Grass clippings and dirt can build up quickly, especially if you're mowing regularly. Make it a habit to clean your mower after each use. This prevents buildup that can cause rust and reduce efficiency. Use a garden hose to spray off grass clippings from the deck and blades. For tougher debris, a plastic scraper can help remove the stuck-on grass and dirt without damaging the mower. Keeping the mower clean also helps you spot any potential issues early, like cracks or loose parts.

Deep Cleaning: Every few weeks, give your mower a more thorough cleaning. Remove the deck and clean out any buildup that might have accumulated in hard-to-reach places. This helps prevent rust and keeps everything running smoothly. Using a pressure washer can make this job easier and more effective. Be sure to dry the mower thoroughly after washing to prevent rust. Applying a light coat of oil or a rust inhibitor on metal parts can provide extra protection.

Engine Care

Oil Check and Change: Just like a car, your mower's engine needs clean oil to run efficiently. Check the oil level regularly—best practice is before each use—and change it according to the manufacturer’s recommendations. Typically, you should change the oil every 50 hours of use or at the start of each mowing season. Using the right type of oil is crucial—refer to your mower's manual to ensure you're using the recommended oil type. Changing the oil regularly helps remove contaminants and keeps the engine lubricated, reducing wear and tear.

Air Filter Maintenance: A dirty air filter can restrict airflow to the engine, causing it to run less efficiently and potentially leading to damage over time. Clean or replace the air filter regularly to maintain optimal engine performance. Foam filters can be washed with soap and water, dried thoroughly, and then lightly oiled before reinstalling. Paper filters should be replaced when dirty. A clean air filter not only improves engine performance but also extends its lifespan by preventing dirt and debris from entering the engine.

Blade Maintenance

Sharp Blades for a Clean Cut: Sharp blades make clean cuts, which are better for your grass and reduce the workload on the mower. Dull blades can tear the grass, leaving it more susceptible to diseases and pests. Sharpen the blades at least twice a season, or more often if you mow frequently. If you hit a rock or other hard object, check the blades for damage and sharpen as needed. Using a file or a bench grinder can make the sharpening process easier. After sharpening, balance the blades to prevent vibrations that can damage the mower.

Blade Replacement: Sometimes, sharpening isn’t enough, and the blades need to be replaced. Inspect the blades regularly for signs of wear and tear, such as thinning metal, cracks, or large chips. Replace them if they’re too damaged to be sharpened effectively. Using high-quality replacement blades can ensure better performance and longevity. Remember, working with sharp blades can be dangerous, so always take safety precautions, like wearing gloves and disconnecting the spark plug before working on the blades.

Tire and Fuel System Maintenance

Proper Tire Care: Proper tire pressure ensures an even cut and makes it easier to maneuver your mower. Check the tire pressure regularly and inflate them to the recommended PSI, which you can usually find in the mower’s manual. Inspect the tires for any signs of wear or damage, such as cracks, splits, or punctures. Keeping the tires in good condition not only improves performance but also extends their lifespan. If you notice uneven tire wear, it might be time to rotate the tires or check for alignment issues.

Fuel System Tips: Using fresh fuel is essential for maintaining engine performance. Old fuel can degrade and cause starting issues or poor performance. Add a fuel stabilizer to the gas tank to prevent the fuel from breaking down, especially if you’re storing the mower for an extended period. Running the engine for a few minutes after adding the stabilizer helps distribute it throughout the system. If you’re storing the mower for the winter, consider draining the fuel tank completely or running the engine until it’s out of gas to prevent any fuel-related issues.

Advanced Maintenance

Spark Plug Check: A clean spark plug ensures efficient combustion and smooth engine operation. Check the spark plug at least once a season and replace it if it’s dirty, corroded, or worn out. Use a spark plug wrench to remove the old plug and install the new one. Ensuring the spark plug is properly gapped according to the manufacturer’s specifications is crucial for optimal performance. Regularly checking and replacing the spark plug can prevent starting problems and improve fuel efficiency.

Lubricate Moving Parts: Keep the moving parts of your mower well-lubricated to ensure they operate smoothly and reduce wear. This includes the wheels, axles, and any other pivot points. Check the manufacturer’s manual for the recommended lubrication points and intervals. Using a high-quality lubricant can extend the life of these components and prevent rust and corrosion. Regular lubrication not only improves performance but also makes the mower easier to operate.

Taking care of your lawn mower doesn’t have to be complicated. With a little regular maintenance, you can extend the life of your mower and keep it running efficiently.
