The first sunny days of spring are here, and you’re eager to get your lawn looking pristine. You’ve pulled your trusty riding lawn mower out of storage, but as you reach for the key, a wave of uncertainty washes over you. How do you even start this thing? Don’t worry, this article will guide you through the process, from basic steps to troubleshooting tips, ensuring you’re mowing in no time. We’ll cover everything from prepping your mower to identifying and addressing common starting issues. So, let’s get your engine roaring and your grass looking beautiful!
Starting a riding lawn mower is a fairly straightforward process, but it does involve a few key steps. You’ll need to make sure the mower is properly fueled, the battery is charged, and the engine is properly primed. You’ll also need to check the choke and throttle settings, as well as the spark plug. Once you’ve completed these steps, starting the engine is simply a matter of turning the key and pulling the starter cord (for pull-start mowers).
Preparing Your Riding Lawn Mower
Before you can even think about starting your riding lawn mower, you need to make sure it’s ready to go. This involves a few essential pre-start checks:
Fueling Up
The first step is to ensure your mower has enough fuel.
- Check the fuel level: Locate the fuel tank, which is usually on the side or rear of the mower. Look at the fuel gauge or use a dipstick to check the fuel level. If it’s low, add fuel.
- Use the right fuel: Riding lawn mowers generally use gasoline, often a blend of gasoline and ethanol. Check your owner’s manual for the recommended fuel type and octane rating.
- Avoid stale fuel: If your fuel has been sitting for a while (more than a few months), it’s best to drain it and replace it with fresh fuel. Stale fuel can cause starting problems and damage the engine.
Battery Check (For Electric Start Mowers)
If your mower has an electric start, you’ll need to check the battery:
- Inspect the battery terminals: Make sure the terminals are clean and free of corrosion. If necessary, use a wire brush to clean them.
- Check the battery voltage: Use a voltmeter to check the battery’s voltage. A fully charged battery should read around 12.6 volts. If the voltage is low, charge the battery.
Getting Ready to Start
With the fuel and battery checked, you can move on to the pre-start procedures:
Choke and Throttle Settings
The choke and throttle control the air and fuel mixture going into the engine:
- Choke: The choke restricts airflow, enriching the fuel mixture for easier starting. On most riding lawn mowers, you’ll find the choke lever near the ignition switch or steering wheel.
- Throttle: The throttle controls the engine speed. Set it to a low speed for starting. You’ll usually find the throttle lever near the steering wheel.
Spark Plug Check (Optional)
While not a routine pre-start check, inspecting the spark plug can sometimes help identify starting problems:
- Locate the spark plug: It’s usually located under the engine cover, near the top of the cylinder head.
- Remove the spark plug: Use a spark plug socket to loosen and remove the plug.
- Inspect the spark plug: The tip of the plug should be clean and have a gap of about .030 inches. If it’s fouled or the gap is incorrect, replace the plug.
Starting the Engine
Finally, it’s time to fire up your mower! Here’s how to do it:
Starting a Gas-Powered Mower
- Engage the parking brake: Always engage the parking brake before starting the engine.
- Set the choke: If the engine is cold, engage the choke.
- Turn the key: Turn the key to the start position.
- Release the choke: Once the engine starts, gradually release the choke.
- Increase the throttle: Slowly increase the throttle to bring the engine up to speed.
Starting a Pull-Start Mower
- Engage the parking brake: Always engage the parking brake before starting the engine.
- Set the choke: If the engine is cold, engage the choke.
- Pull the starter cord: Grasp the starter cord handle and pull it firmly and quickly.
- Release the choke: Once the engine starts, gradually release the choke.
- Increase the throttle: Slowly increase the throttle to bring the engine up to speed.
Troubleshooting Starting Problems
Even with careful preparation, sometimes your riding lawn mower may refuse to start. Here are some common problems and their solutions:
1. Dead Battery
If the battery is dead, the starter motor won’t be able to turn the engine over.
- Solution: Charge the battery or replace it with a new one.
2. Fuel Problems
Fuel problems are a common reason for starting issues.
- Empty tank: Ensure the fuel tank is not empty.
- Stale fuel: Drain and replace the fuel with fresh gasoline.
- Clogged fuel lines: Check the fuel lines for clogs and clear them if necessary.
3. Air Filter Clogging
A dirty air filter restricts airflow to the engine, making it difficult to start.
- Solution: Clean or replace the air filter.
4. Spark Plug Issues
A fouled or damaged spark plug can prevent the engine from igniting.
- Solution: Inspect and clean or replace the spark plug.
5. Choke Problems
If the choke is not working properly, the engine may not receive the right fuel mixture.
- Solution: Check the choke linkage and adjust or repair it as needed.
6. Ignition System Problems
The ignition system is responsible for generating the spark that ignites the fuel mixture.
- Solution: If you suspect a problem with the ignition system, it’s best to have it inspected and repaired by a qualified mechanic.
Tips for Successful Starting
- Read your owner’s manual: The owner’s manual contains detailed instructions for starting your specific model.
- Check the engine oil level: Make sure the engine has enough oil before starting.
- Use fresh fuel: Avoid using old or stale fuel.
- Clean the air filter regularly: This will help ensure proper airflow.
- Inspect the spark plug: Replace it if it’s fouled or damaged.
- Don’t overfill the fuel tank: Leave some space in the tank to allow for fuel expansion.
- Store the mower properly: When not in use, store the mower in a dry place with the fuel tank empty.
