Understanding Lawn Mowers
Lawn mowers are essential tools for maintaining a neat and healthy lawn. Knowing the types and common issues related to them can make a big difference when trying to start one that has been sitting.
Types of Lawn Mowers
- Push Lawn Mowers: Ideal for small to medium-sized yards, these mowers require physical effort to operate. You control their movement while the blades cut the grass.
- Self-Propelled Lawn Mowers: These mowers do the heavy lifting for you. They use a drive system to move forward, meaning you only need to guide them.
- Riding Lawn Mowers: Best for larger properties, riding mowers allow you to sit and drive while cutting grass. These mowers cover more ground efficiently and reduce fatigue.
- Robotic Lawn Mowers: Increasingly popular, these automated devices mow the lawn on their own. You program them to follow specific patterns and they require minimal oversight.
- Electric Lawn Mowers: These mowers rely on electricity. They can be corded or battery-operated, offering quieter and more eco-friendly options compared to gas mowers.
- Fuel Degradation: Gasoline loses its combustibility after a few months. If your mower’s fuel has been sitting, it may not ignite properly.
- Oil Contamination: Oil can also break down over time, thickening and losing its effectiveness. Check your oil level and condition before starting.
- Clogged Fuel Lines: Dirt and debris can build up in fuel lines, preventing gas from flowing smoothly. Inspect and clean these lines as needed.
- Battery Drain: If your mower has an electric start, the battery may lose charge when idle. Ensure it’s charged or replace it when necessary.
- Stale Spark Plug: Old spark plugs can hinder ignition. Inspect the spark plug for wear, and replace it if necessary to ensure a strong spark.
Taking the time to understand your lawn mower can simplify the process of getting it started, especially after it has sat idle for a while.
Preparing to Start the Lawn Mower
Preparing your lawn mower for starting requires some essential steps. Following these guidelines ensures you address potential issues from it sitting idle.
Gathering Necessary Tools
Gather these tools before starting the process:
- Fresh Gasoline: Use unleaded fuel suitable for small engines.
- Oil: Check and refill engine oil as needed using a high-quality oil.
- Spark Plug Wrench: Needed for inspecting and replacing the spark plug.
- Screwdriver: Useful for removing any panels and making adjustments.
- Fuel Stabilizer: Reduces deterioration of gasoline and aids start-up.
Collect these items to streamline the preparation process. A well-equipped workspace improves efficiency.
Safety Precautions
Adhering to safety precautions ensures your safety while starting the mower. Consider these tips:
- Wear Gloves: Protect your hands from sharp edges and hot parts.
- Use Safety Goggles: Shield your eyes from dust and debris.
- Disconnect the Spark Plug: Prevent accidental starts while performing maintenance.
- Ensure Proper Ventilation: Work in an open area to avoid inhaling fumes.
- Keep Kids and Pets Away: Ensure a safe environment while working on the mower.
Implementing safety measures protects you during the preparation phase. Stay aware and focused as you work on your lawn mower.
Steps to Start a Lawn Mower That Has Been Sitting
Getting your lawn mower up and running after it’s been sitting requires a few essential steps. Follow these instructions to tackle the process with confidence.
Check the Fuel
Inspect the fuel tank. Stale gasoline can create starting issues. If you’ve stored gas for more than 30 days, it’s best to drain it and refill with fresh gasoline. Use a fuel stabilizer if you’re storing fuel in the future. This helps maintain its quality and makes starting your mower easier.
Inspect the Oil
Examine the oil level and condition. Old oil can become thick and sludgy, affecting engine performance. If the oil looks dark or dirty, change it before starting. Use the appropriate grade of oil for your mower and fill it to the correct level as indicated in the owner’s manual.
Examine the Spark Plug
Remove and check the spark plug. A worn or fouled spark plug can prevent ignition. Clean the spark plug with a wire brush or replace it if it’s showing signs of wear, such as corrosion or damage. Ensure the gap on the spark plug aligns with the mower’s specifications for proper performance.
Clean or Replace the Air Filter
Check the air filter for dirt or debris. A clogged air filter restricts airflow, hindering engine performance. Clean reusable filters with soap and water, or replace disposable filters if they’re too dirty. A clean air filter promotes better combustion and helps the engine run smoothly.
Prime the Engine
If your mower has a primer bulb, press it several times to force fuel into the carburetor. This step preps the engine for starting. Adjust the choke to the correct setting based on your mower’s requirements. This combination of priming and adjusting allows your mower to start more easily after sitting for a while.
Troubleshooting Common Problems
Starting a lawn mower that has been sitting can lead to several common issues. Here’s how to troubleshoot these problems effectively.
Engine Won’t Start
If the engine doesn’t start, check the fuel first. Stale fuel can cause starting problems. Drain the old fuel and replace it with fresh gasoline. Inspect the battery connections; corrosion can hinder performance. Clean the connectors or replace the battery if it appears weak. Also, ensure the spark plug isn’t dirty or worn out. If it is, clean or replace it for optimal ignition.
Rough Idling
Rough idling can often result from clogged air filters or fuel lines. Remove and clean the air filter to improve airflow. Additionally, inspect the fuel lines for blockages. Clear any dirt or debris obstructing the lines to restore proper fuel flow. Adjust the throttle appropriately, as improper throttle settings affect engine performance.
Excessive Smoke
Excessive smoke can indicate oil contamination or an overfilled oil reservoir. Check the oil level; if it’s too high, drain the excess oil. Use the correct oil type for your mower to prevent smoke due to burning improper oil. Additionally, inspect the spark plug for fouling, which can also contribute to smoking. Clean or replace the spark plug if necessary to reduce smoke emissions.
Maintenance Tips for Longevity
Taking proper care of your lawn mower ensures it runs smoothly and serves you for years. Regular maintenance helps prevent many common problems that can arise from inactivity. Follow these guidelines for optimal mower performance.
Regular Use Recommendations
Use your lawn mower regularly to maintain engine health. Mowing every 1-2 weeks during the growing season keeps fuel fresh and prevents the engine components from seizing. If you can’t mow weekly, run the engine for 10-15 minutes every few weeks. This circulation keeps oil moving and prevents fuel from going stale.
Seasonal Maintenance Checklist
Adhering to a seasonal maintenance checklist reduces the chance of issues over time.
Here are the essential tasks to perform:
- Spring Maintenance
- Change the oil using manufacturer-recommended oil.
- Replace or clean the air filter to ensure proper airflow.
- Inspect the blades for sharpness and sharpen them if dull.
- Summer Maintenance
- Check the fuel level regularly to avoid running on empty.
- Inspect the spark plug, cleaning or replacing it as necessary.
- Clean the mower deck after each use to prevent grass buildup.
- Fall Maintenance
- Change the oil again to remove contaminants built up during the season.
- Add fuel stabilizer before storing the mower.
- Store the mower in a dry, sheltered place to protect it from moisture.
- Winter Maintenance
- Perform a thorough inspection before storing.
- Disconnect the battery if applicable.
- Keep the mower covered to protect it from dust and pests.
Following these tips during each season keeps your lawn mower in excellent condition, ensuring easy starts and effective performance whenever you need to trim your grass.
Conclusion
Getting your lawn mower started after it’s been sitting doesn’t have to be a hassle. With a little preparation and the right approach you can breathe new life into your mower and get back to maintaining that beautiful yard.
Remember to prioritize safety and follow the steps carefully. Regular maintenance is key to preventing future issues and ensuring your mower runs smoothly. By keeping up with routine checks and using your mower regularly you’ll save yourself time and frustration down the road.
So roll up your sleeves and get that mower humming again. Your lawn will thank you!
