Getting Ready to Start Your Lawn Mower
Before you even think about pulling the starter cord, there are a few essential steps to take to ensure your lawn mower is ready to roar back to life. These steps will help you identify potential issues early on and set yourself up for success.
1. Safety First:
- Wear protective gear: Always wear eye protection, gloves, and sturdy footwear when working on a lawn mower.
- Disconnect the spark plug: This will prevent the engine from starting accidentally while you’re working on it.
2. Cleaning and Inspection:
- Remove debris and grass: A build-up of debris can interfere with the engine’s operation. Clean the mower thoroughly, paying special attention to the air filter and spark plug area.
- Check the fuel: Old fuel can gum up the carburetor and prevent the engine from starting. Drain any existing fuel and replace it with fresh, high-octane gasoline.
- Inspect the spark plug: The spark plug is responsible for igniting the fuel-air mixture. If it’s corroded or damaged, it will need to be replaced.
- Check the air filter: A clogged air filter restricts airflow to the engine, reducing its performance.
3. Preparing the Engine:
- Add oil: Make sure the engine has enough oil. Consult the owner’s manual for the correct type and amount.
- Prime the carburetor (gas mowers only): If your lawn mower has a carburetor, you’ll need to prime it to get fuel flowing. This typically involves pumping a primer bulb until you see fuel flowing into the carburetor.
- Inspect the battery (electric mowers only): If your lawn mower is electric, check the battery’s charge level. If the battery is dead, you’ll need to recharge or replace it.
Starting Your Lawn Mower: The Gas Mower Edition
Once you’ve completed the preparation steps, you’re ready to attempt starting your gas-powered lawn mower. Follow these steps:
1. Open the Fuel Valve: If your mower has a fuel valve, make sure it is open.
2. Position the Choke: The choke restricts airflow, helping the engine start more easily. Most lawn mowers have a choke lever or knob; set it to the “choke” position.
3. Pull the Starter Cord: Slowly pull the starter cord a few times to build up some pressure in the cylinder. Then, pull the cord briskly and smoothly until the engine starts.
Troubleshooting Common Problems:
- If the engine coughs and sputters but doesn’t start: The problem could be a clogged carburetor, a weak spark, or a lack of fuel. Check the fuel line for any blockages, clean the carburetor, and inspect the spark plug.
- If the engine starts but dies immediately: This could indicate a lack of fuel, a blocked air filter, or a faulty carburetor. Check the fuel tank, inspect the air filter, and consider cleaning the carburetor.
Starting Your Lawn Mower: The Electric Mower Edition
Electric lawn mowers are generally easier to start than their gas-powered counterparts. Simply follow these steps:
1. Plug in the Cord: Make sure the extension cord is long enough to reach the area where you plan to mow.
2. Turn on the Mower: Locate the power switch and flip it to the “on” position.
3. Engage the Blades: Most electric mowers have a lever or button to engage the blades.
Troubleshooting Common Problems:
- If the mower doesn’t start: Check the power cord for damage and make sure the outlet is working.
- If the mower runs but the blades don’t turn: Ensure the blade engagement mechanism is working properly.
Keeping Your Lawn Mower Running Strong
Now that you’ve successfully brought your lawn mower back to life, it’s important to maintain it properly to ensure its longevity. Here are some tips:
1. Regular Maintenance:
* Change the oil: Change the engine oil regularly, as recommended in your owner’s manual.
* Clean the air filter: A clean air filter is essential for proper engine performance.
* Replace the spark plug: Replace the spark plug as needed, based on your owner’s manual recommendations.
* Inspect and clean the carburetor: Periodically inspect and clean the carburetor to prevent clogging.
2. Storage:
* Store the mower properly: When not in use, store the mower in a clean, dry place.
* Drain the fuel: If you’re storing the mower for an extended period, drain the fuel tank to prevent fuel from going bad.
Beyond the Basics: Additional Tips
1. Don’t Give Up: Starting a lawn mower that’s been sitting for years can be challenging, but don’t give up! Patience and persistence are key.
2. Consult Your Owner’s Manual: The owner’s manual is your best resource for troubleshooting and maintenance information.
3. Consider Professional Help: If you’re struggling to start your lawn mower, don’t hesitate to seek professional help from a qualified small engine repair shop.

Bringing a dormant lawn mower back to life can be a rewarding experience. With the right steps and a little bit of patience, you can have your mower running smoothly in no time. Remember to prioritize safety, perform thorough inspections, and follow the advice in your owner’s manual. With a bit of effort, you can get your lawn mower ready to tackle those overgrown patches and keep your yard looking its best.
FAQ
Q1. What should I do before attempting to start the lawn mower?
A1. Before you even attempt to start the lawn mower, safety should be your top priority. Start by checking the fuel lines and tank for any cracks or leaks. Ensure the fuel is fresh and not old or stale. If the gas is older than 3 months, it is best to replace it. Inspect the spark plug wires and ensure they are properly connected and not damaged. Finally, clear the area around the mower of any debris or flammable materials to prevent accidents.
A2. Next, you’ll want to prepare the mower for starting. Make sure the lawn mower is on a flat surface. Inspect the oil level and top it up if necessary. You should also check the air filter and clean or replace it if needed.
Q2. What are the steps to starting a lawn mower after years of sitting?
A2. Starting a neglected lawn mower can be a bit tricky, but following these steps should help: First, remove the spark plug and add a few drops of oil into the cylinder. Replace the spark plug and turn the engine over a few times to distribute the oil. Then, pour fresh fuel into the tank. Make sure you have a good spark at the spark plug before attempting to start the engine.
A3. With everything in place, you can try starting the mower. If the mower is a manual start, try pulling the cord vigorously. If it’s an electric start, connect the battery and engage the starter. If it doesn’t start right away, don’t give up. Try using a spray starter fluid to help ignite the fuel.
Q3. What if the lawn mower still won’t start?
A3. If the lawn mower still doesn’t start, there could be a few issues. Check the fuel lines for any blockages or kinks. Inspect the carburetor for debris or clogging. Ensure the spark plug is firing properly and replace it if necessary. You may also need to check the battery terminals for corrosion and clean them if necessary.
