Overview
Maintaining your lawnmower is about more than just a quick oil change. It’s about understanding the different components and their importance, carrying out regular checks, and knowing when to call for professional assistance. By following these tips, you can keep your lawnmower running smoothly and efficiently for years to come.
Pre-Season Preparation: Getting Your Lawn Mower Ready to Roll
As the days get longer and the sun shines brighter, your lawnmower needs to be ready for action. Before you fire it up, it’s essential to perform a thorough pre-season inspection to ensure a smooth start to your mowing season.
1. A Clean Machine is a Happy Machine
Start by giving your lawnmower a good cleaning. A build-up of grass clippings, dust, and debris can hinder its performance and even cause damage over time.
- Remove the spark plug wire: For safety, always disconnect the spark plug wire before starting any maintenance.
- Use a brush or compressed air: Clean the engine, deck, and underside thoroughly, removing any accumulated debris.
- Check the air filter: A dirty air filter restricts airflow, causing performance issues. Clean or replace it if necessary.
- Clean the cutting deck: Remove any grass clippings and debris from the underside of the deck.
2. Sharp Blades for a Clean Cut
Sharp blades are crucial for a clean cut and a healthy lawn. Dull blades can tear the grass, leading to browning and disease.
- Sharpening: Sharpen the blades with a file or take them to a professional for sharpening.
- Balancing: Once sharpened, ensure the blades are balanced to prevent vibrations that can damage the mower.
- Inspect for damage: Look for any cracks, chips, or other damage. Replace any severely damaged blades.
3. Checking Fuel and Oil
Your lawnmower needs fuel and oil to function properly.
- Fuel: Use fresh, high-quality gasoline. Avoid storing fuel for extended periods, as it can degrade and cause engine problems.
- Oil: Check the oil level and top it up if necessary. Use the recommended oil type for your mower.
- Spark Plug: Inspect the spark plug for wear and tear and replace it if necessary. A worn spark plug can lead to poor engine performance.

- Remove grass clippings: Clean the cutting deck and other areas of the mower where grass clippings tend to accumulate.
- Check for loose parts: Ensure all nuts, bolts, and screws are tight.
- Inspect for damage: Look for any signs of damage or wear and tear.
3. Seasonal Maintenance: Fall and Winter Prep
At the end of the mowing season, perform some extra maintenance to prepare your lawnmower for storage.

Frequently Asked Questions
FAQ 1: How often should I service my lawn mower?
It is recommended to service your lawn mower at least once a year, ideally before the start of the mowing season. This ensures that your mower is in optimal condition and ready to tackle the workload.
Regular servicing will prevent unexpected breakdowns during peak mowing season. It also helps extend the lifespan of your mower by catching and addressing potential issues early on.
FAQ 2: What are the essential parts to check before each mow?
Before each mow, it’s crucial to perform a quick safety check. Ensure the spark plug is connected, the blades are sharp and securely attached, the fuel level is adequate, and the air filter is clean.
Additionally, inspect the mower for any loose parts, cracks, or damage. These simple checks can prevent accidents and ensure smooth operation.
FAQ 3: How do I know if my mower blade needs sharpening?
A dull blade will tear and shred the grass, leaving an uneven and unhealthy lawn. Signs of a dull blade include ragged edges on the grass, a brown or yellow appearance, and excessive noise during mowing.
If you notice any of these signs, it’s time to sharpen your blades. You can sharpen them yourself using a sharpening stone or take them to a professional for a professional sharpening.
FAQ 4: What type of oil should I use for my lawn mower?
The type of oil you need depends on your lawn mower’s engine. Most modern mowers require a 4-stroke oil, specifically SAE 30 or 10W-30.
Check your owner’s manual for the recommended oil type and viscosity for your specific model. Using the wrong oil can damage your engine.
FAQ 5: How do I safely change the oil in my lawn mower?
Changing the oil is a simple process. First, allow the engine to cool down completely. Then, place a drain pan under the engine and unscrew the drain plug to let the oil drain. Replace the plug and fill the engine with the recommended oil using the dipstick as a guide.
Be cautious with hot oil and dispose of used oil properly.
FAQ 6: How often should I change the air filter?
A clean air filter is essential for optimal engine performance. A dirty filter restricts airflow and can cause the engine to run poorly.
The frequency of air filter changes depends on usage and environmental conditions. However, it’s a good practice to check and clean the filter every few mows, and replace it at least once a season.
FAQ 7: How do I prepare my lawn mower for winter storage?
Before storing your mower for winter, give it a thorough cleaning, removing all grass clippings and debris. Drain the fuel tank and carburetor to prevent gumming.
Lubricate moving parts, such as the wheels and blades. Cover the mower with a tarp or store it in a dry place to protect it from the elements.
