Starting a lawn mower that has been sitting idle for years can be a daunting task, but with the right approach, you can breathe new life into your old machine. Whether you’re looking to save money by not buying a new mower or simply want to get your trusty old companion running again, this guide will walk you through the process step by step. The key to success lies in understanding the potential issues that arise from years of inactivity and tackling them methodically.
Understanding the Challenges
Lawn mowers, like any other piece of machinery, require regular maintenance to ensure they continue to function properly. When a mower sits for years, several issues can develop that make it difficult to start. These include:
- Fuel degradation: Gasoline can break down over time, leading to varnish and gum formation that can clog the fuel system.
- Rust and corrosion: Moisture can accumulate, causing rust on metal parts and corrosion on electrical components.
- Dead battery: If your lawn mower is electric or has an electric start, the battery may have lost its charge over time.
- Stale oil: Engine oil can become thick and less effective, potentially damaging the engine if not changed.
Preparation is Key
Before attempting to start your lawn mower, it’s essential to prepare it for the challenges ahead. This involves a series of checks and maintenance tasks designed to mitigate the effects of prolonged inactivity.
Drain Old Fuel
The first step in preparing your lawn mower for start-up is to drain the old fuel. This is crucial because old gasoline can cause more problems than it solves. Always use proper safety equipment, including gloves and safety glasses, when handling fuel. Once the tank is empty, you can move on to cleaning the fuel system.
Clean the Fuel System
Cleaning the fuel system involves removing any debris, varnish, or gum that may have formed. You can use a fuel system cleaner or consult a professional for more complex issues. Remember, patience is key; rushing this process can lead to further complications.
Recommissioning the Engine
With the fuel system cleaned, it’s time to focus on the engine itself. This involves checking the oil, spark plug, and air filter.
Oil Check and Change
Check the engine oil for viscosity and condition. If it’s thick or dirty, it’s best to change it to ensure the engine runs smoothly and to prevent any damage. Use the type of oil recommended by the manufacturer to avoid any compatibility issues.
Spark Plug Maintenance
A spark plug in poor condition can prevent your lawn mower from starting. Remove the spark plug and inspect it for wear. If it’s dirty, you can clean it with a spark plug cleaner. However, if it’s worn out, consider replacing it with a new one.
Air Filter Check
The air filter plays a critical role in ensuring your lawn mower gets the air it needs to run efficiently. Check the air filter for dust and debris. Clean or replace it as necessary to ensure optimal performance.
Electrical and Battery Considerations
For lawn mowers with electric start or lights, the electrical system and battery condition are crucial.
Battery Check and Charge
If your lawn mower has a battery, check its condition. If it’s old or has been discharged for a long time, it might need replacing. Otherwise, charge the battery according to the manufacturer’s instructions. Ensure all electrical connections are clean and secure to prevent any issues.
Other Electrical Components
In addition to the battery, inspect other electrical components such as the starter motor, ignition coil, and spark plug wire for signs of wear or damage. Cleaning or replacing these parts may be necessary to get your mower running.
Final Steps to Starting Your Lawn Mower
With preparation and maintenance out of the way, it’s time to attempt to start your lawn mower.
Prime the Engine
If your lawn mower has a primer bulb, use it to prime the engine. This helps ensure fuel reaches the carburetor, making it easier to start.
Starting the Engine
Pull the starter cord slowly until you feel resistance, then pull it sharply to start the engine. If it doesn’t start right away, don’t worry. It may take a few attempts, especially if the mower has been sitting for a long time.
Troubleshooting
If your lawn mower still doesn’t start, troubleshoot the issue. Check for spark, ensure the fuel valve is open, and verify that the choke is in the correct position. Sometimes, consulting the user manual or seeking professional help may be the best course of action.
Conclusion
Starting a lawn mower that has been sitting for years requires patience, the right approach, and a bit of elbow grease. By following this guide, you’ll be well on your way to reviving your dormant lawn mower and getting back to a well-manicured lawn. Remember, regular maintenance is key to preventing these issues in the future. Keep your lawn mower in good condition, and it will serve you well for years to come.
What are the common reasons why a lawn mower becomes dormant?
A dormant lawn mower can be a frustrating and challenging problem to tackle, especially when the grass is growing rapidly and needs to be cut. One of the most common reasons why a lawn mower becomes dormant is a lack of maintenance. If the oil is not changed regularly, the filter is not cleaned or replaced, and the spark plug is not checked, the engine can seize or fail to start. Additionally, leaving gas in the tank for an extended period can cause the fuel to break down and clog the carburetor, making it difficult to start the engine.
To avoid these issues, it is essential to perform regular maintenance tasks, such as changing the oil, cleaning or replacing the air filter, and checking the spark plug. It is also crucial to store the lawn mower properly during the off-season, by draining the gas tank, cleaning the mower deck, and applying a rust-inhibiting coating to the metal parts. By following these simple maintenance tasks, you can prevent your lawn mower from becoming dormant and ensure it starts easily when you need it. Regular maintenance can also help extend the lifespan of your lawn mower, saving you money and reducing the need for costly repairs.
How do I prepare my dormant lawn mower for revival?
Before attempting to revive your dormant lawn mower, it is essential to prepare it properly. Start by cleaning the mower deck and removing any debris, leaves, or twigs that may have accumulated. Next, inspect the air filter and clean or replace it if necessary. Check the spark plug and replace it if it is worn out or damaged. It is also crucial to check the oil level and top it off if necessary. If the gas tank is empty, fill it with fresh gas, and if the tank is not empty, drain the old gas and replace it with new fuel.
Preparing your lawn mower for revival involves more than just cleaning and inspecting the parts. It also requires making sure the mower is in a safe and stable condition. Check the tires for proper inflation, and make sure the mower is on a level surface. If the lawn mower has been stored for an extended period, it is a good idea to check the blade for rust or damage and sharpen or replace it if necessary. By taking the time to properly prepare your lawn mower, you can ensure a successful revival and get back to cutting your grass with ease.
What are the steps involved in reviving a dormant lawn mower?
Reviving a dormant lawn mower involves a series of steps that require patience, attention to detail, and some mechanical aptitude. The first step is to diagnose the problem and identify the root cause of the issue. This may involve checking the spark plug, air filter, and fuel system to determine if there are any blockages or worn-out parts. Next, clean or replace the air filter, and check the spark plug to ensure it is in good condition. If the spark plug is worn out, replace it with a new one.
Once the diagnosis is complete, and the necessary repairs have been made, it is time to start the engine. Begin by priming the engine with fresh gas, and then pull the starter cord to turn the engine over. If the engine does not start, check the ignition system and fuel line for any blockages or leaks. If the engine still does not start, it may be necessary to take the lawn mower to a small engine repair shop for further diagnosis and repair. With persistence and the right guidance, it is possible to revive a dormant lawn mower and get it running like new again.
Can I revive my lawn mower on my own, or do I need professional help?
