The thrill of a freshly mowed lawn is quickly replaced with dread when you realize you’ve just submerged your lawn mower in water. Whether it was a sudden downpour, a slip while crossing a stream, or a clumsy moment with the hose, a flooded lawn mower can be a major headache. This article will guide you through the steps to take after your lawn mower takes an unexpected swim, helping you diagnose the problem, understand the potential damage, and get your mower back in working order. We’ll also explore preventive measures you can take to avoid this unfortunate situation in the future.
Short Overview
A flooded lawn mower requires immediate action to prevent further damage. This guide will cover the essential steps to take, from initial assessment to drying, cleaning, and potential repairs. Understanding the severity of the flood and the type of engine your mower uses will help determine the best course of action.
Step 1: Immediate Action – Assessing the Damage
The first thing to do is assess the damage and act quickly to minimize potential harm.
1.1 Turn off the Engine & Disconnect the Battery (If Applicable)
The first step is to stop the engine immediately if it’s running. If the engine is still hot, avoid restarting it. For gasoline-powered mowers, disconnect the battery terminals to prevent any electrical shorts.
1.2 Remove Excess Water & Upright the Mower
Once the engine is off, tilt the mower to allow excess water to drain. Be careful not to damage the engine or other components while doing so. If the mower is submerged, carefully lift it out of the water and place it upright.
1.3 Evaluate the Severity
Carefully inspect the mower for signs of water damage. Look for water in the engine compartment, air intake, spark plug area, and fuel system. If the water level reached the air intake, the engine might have water in the cylinders, which can be serious.
Step 2: Drying and Cleaning
2.1 Dry the Mower Thoroughly
After removing excess water, dry the mower as thoroughly as possible. Use a towel or a hairdryer on a low setting to dry the engine compartment, air intake, and spark plug area. Pay special attention to the air filter, which can absorb significant amounts of moisture.
2.2 Cleaning the Mower
Once the mower is dry, it’s essential to clean it thoroughly. This will help remove any remaining dirt and debris that could cause further problems. Use a mild detergent and a soft brush to clean the exterior of the mower. Avoid using high-pressure water jets, as they could force water into sensitive components.
2.3 Attention to the Air Filter
Pay close attention to the air filter, as it’s especially prone to water damage. If the air filter is soaked, it needs to be replaced. You can try to salvage a slightly damp air filter by allowing it to air dry completely, but a heavily soaked air filter should be replaced.
Step 3: Engine Inspection & Potential Repairs
3.1 Gasoline vs. Electric Engines
The type of engine your mower uses determines the extent of potential damage and the required repair process.
- Gasoline Engines: These engines are more susceptible to water damage because the fuel system is more complex. Water can enter the cylinders, carburetor, and fuel lines, leading to significant problems.
- Electric Engines: Electric engines are less susceptible to water damage because they have fewer moving parts. However, water can still damage the motor or the electrical wiring.
3.2 Checking for Spark
If your mower has a gasoline engine, it’s crucial to check for spark. A spark plug tester can help determine if the spark plug is functioning correctly. If there is no spark, the spark plug may need to be cleaned or replaced.
3.3 Diagnosing Fuel System Issues
If the water reached the fuel system, it can contaminate the fuel and lead to engine problems. A mechanic can help determine if the fuel system needs to be cleaned or replaced.
3.4 Potential Engine Problems
If your lawn mower’s engine is flooded, it may experience various problems:
- Engine Won’t Start: Water in the cylinders can prevent the engine from starting.
- Rough Idling or Stalling: Water in the fuel system can cause the engine to run rough or stall.
- Loss of Power: Water in the cylinders or the fuel system can reduce engine power.
- Engine Damage: In severe cases, water can cause permanent engine damage.
3.5 Seeking Professional Help
If you’re not comfortable diagnosing and repairing the engine yourself, it’s best to take the mower to a qualified mechanic. They can assess the extent of the damage and recommend the appropriate repairs.
Step 4: Preventing Future Floods
4.1 Storing Your Mower Properly
Proper storage can help prevent future water damage. Keep your mower in a dry, well-ventilated area. If possible, cover it with a waterproof tarp or cover.
4.2 Avoid Using the Mower in Wet Conditions
Whenever possible, avoid using your mower in wet conditions. If you must use it in wet grass, be mindful of puddles and avoid driving through standing water.
4.3 Choosing the Right Mower
Consider investing in a mower designed for wet conditions, such as a riding mower with a high ground clearance or a mulching mower that can handle wet grass.
Conclusion: A Flooded Mower Doesn’t Have to Mean Disaster
Facing a flooded lawn mower can be frustrating, but with prompt action and proper care, you can often salvage your mower and get it back in working order. Remember to assess the damage, dry the mower thoroughly, and address any engine issues. By taking these steps and implementing preventative measures, you can minimize the risk of future floods and keep your lawn mower running smoothly for years to come.
FAQs
1. My lawn mower was submerged in water. Is it salvageable?
It’s possible, but it depends on the extent of the flooding. If the water level reached the engine, there’s a good chance it suffered significant damage. However, if the water only reached the wheels or deck, it’s more likely to be salvageable with proper cleaning and drying. Start by assessing the damage and determine if the engine was submerged. If it was, it might be best to contact a professional for repair.
2. What should I do immediately after the lawn mower is flooded?
The most important thing is to prevent further damage. Disconnect the spark plug to prevent accidental starting. Then, turn the mower upside down to allow any trapped water to drain. This will help prevent corrosion and other issues. Do not attempt to start the engine until you’ve thoroughly dried the mower. It’s also important to note that even if the mower appears dry, there may still be water trapped in the engine or other components.
3. How can I dry my flooded lawn mower?
The best way to dry a flooded lawn mower is to let it air dry completely. If possible, disassemble as many parts as you can, such as the air filter, spark plug, and fuel tank, and let them dry separately. Place the lawn mower in a well-ventilated area, ideally with a fan blowing on it. If you have access to compressed air, you can use it to blow out any remaining water.
4. How long should I let my lawn mower air dry?
It’s recommended to let the lawn mower air dry for at least 24 hours, and possibly longer depending on the severity of the flooding. The air needs time to reach all the nooks and crannies of the engine and other components. If the lawn mower was submerged for a long period, it may take even longer for it to dry completely. Be patient and allow ample time for drying.
5. What should I do if my lawn mower doesn’t start after drying?
If your lawn mower still won’t start after drying, there are a few things you can try. First, check the spark plug to ensure it’s clean and functioning properly. You can also check the fuel lines for any blockages or damage. If you’ve ruled out these issues, it’s likely the engine has suffered internal damage, and professional repair is recommended.
6. Can I use WD-40 to protect my lawn mower from rust after flooding?
WD-40 can be used to protect metal parts from rust, but it’s not recommended for use on all parts of a lawn mower. It can actually damage rubber and plastic components. You can use a dedicated rust preventative spray, and avoid using WD-40 on sensitive parts.
7. What should I do if my lawn mower is still under warranty after flooding?
If your lawn mower is still under warranty, contact the manufacturer immediately. They may be able to assist with repairs or replacement depending on the terms of your warranty and the extent of the damage. Be sure to document the incident, including any photos or videos, and provide this information to the manufacturer.
