When using the cordless DeWALT 20V leaf blower, one of the most frequent issues is that it stops operating. But while using this outdoor power equipment, you could also run into additional issues. But the fundamental question is why it occurs and how to remedy it.

They produce well-liked electric blowers that may clean your deck, garage, or yard is the DeWALT 20V leaf blower. This indispensable all-year-round tool is portable, making it simpler to maintain a clean yard.

In our guide, before you discover your DeWALT lawn mower keeps shutting off, you find your DeWALT blower shuts off, among other niggles By the end, you’ll see the most common issues and what you need to do to fix your handheld blower. (Read John Deere Fault Codes List)

DeWALT Leaf Blower Will Not Start

It’s likely a power issue if your electric leaf blower won’t start and blow leaves, which is bad if you have a large yard. Check your fuse box or circuit breaker to make sure the outlet is receiving power and make sure it is plugged into an outlet.

Before trying to start the blower once more, you might need to push the “Test” and “Reset” buttons on your outlet’s ground-fault circuit interrupter (GFCI). Take your blower to a servicing facility if it is receiving power, but still won’t start.

If issues persist or you use a corded blower, try a different power outlet or extension cord to rule out a power problem. A voltage tester can check the power switch’s contact, which may also be the source of the issue.

Troubleshooting A Cordless DeWALT Leaf Blower

DeWALT Battery and Charger Troubleshooting

The DeWALT 20v blower problems are like the drawbacks of other cordless tools including their batteries and chargers. The ease of these quality battery-operated handheld blower options is well known, but batteries and chargers fail, and getting rid of these things is a hassle.

DeWALT battery chargers are quality, but occasionally they may malfunction, causing your batteries to eventually drain quickly. Try charging a new battery and comparing the results to an old battery to see if the DeWALT charger needs to be replaced.

Check the battery life when using a handheld blower, and if necessary, let the blower charge for an extended period. Try starting it on and connecting it to a socket. If it does, your handheld blower battery might not start the engine on its own because it has lost wattage from excessive use.

Try testing voltage or capacity instead of using a voltmeter if your battery is externally charged. Better still, try putting in a spare battery in your battery blower to see if that works. You should also check the battery installation, as it won’t work if the contacts don’t touch.

DeWALT Battery Charging Procedure

The following is the proper way to charge your batteries:

  • Battery discharge when used normally. When you see the tool is losing power, remove the battery.
  • Do not tape the trigger in the ON position.
  • To get the battery to room temperature, let it sit outside of the charger for at least 2 hours.
  • Place the battery in the charger overnight to give each cell a complete charge (A minimum of 8 hours at room temperature).

If there is no variation in run-time, the battery has either totally drained, run out of life, or sustained irreparable damage. Therefore, the battery needs to be changed in any scenario.

Leaf Blower Battery Won’t Charge

When the red charging light turns on, place the battery into the charger. If the battery is dead, charge it for up to 8 hours.

  • Connect the charger to a functional outlet.
  • By inserting an appliance into the receptacle, you can check the current.
  • Ensure the outlet is connected to a light switch that turns the power off when the lights are turned off.
  • Move the charger and handheld blower tool to an area where the surrounding air temperature is at least 40 °F (4.5 °C) and no higher than 105 °F (40.5 °C), and there is a working outlet.

How You Reset a DeWALT Battery

DeWALT lightweight cordless leaf blowers eliminate the need for electrical extension cables by using a rechargeable nickel-cadmium battery pack.

The battery packs are long-lasting and quick to charge, but they have a microchip that turns them off if they get too hot.

You must restart the battery pack when it switches off. The microchip’s memory is erased during the reset operation, giving the chip the green light to charge like a fresh battery. (Find the Best Riding Snow Blower)

To reset your battery:

  • To remove the battery pack from the DeWALT power tool, press the battery pack removal button on the rear of the tool’s handle.
  • Slide the battery down the rail track on the power tool’s base.
  • With the metal contact side facing the metal contacts in the charger, insert the battery pack into the battery pack charger.
  • Give the battery pack eight hours to charge until fully charged.
  • You’ve just reset your DeWALT battery pack.

It is rare for damaged wires anywhere around the battery as it works by contact. However, some models may have damaged wires in the harness if it is backpack-style leaf blowers.

An interrupted power supply can cause the blower speed to speed up and slow down. You will need to replace any broken wires.


The impeller, another name for the fan in your handheld blower, contains many fan blades that direct the airflow as it is spinning to produce it. These fan blades can break now and again, and a broken fan blade can cause excessive vibration.

DeWalt flexvolt battery problem

Some leaf blowers have a vacuum attachment. As a result, the fan blades can occasionally be damaged by dirt and debris being sucked up into them. The fan blades may become dirty over time, increasing vibration, which is a widespread problem with lots of use.


In most cases, neither typical use nor normal wear will cause significant vibration from the washers in your leaf blower. Losing a washer, however, may cause excessive vibration of other components like the isolators or impeller.

When a leaf blower is disassembled, washers can occasionally be put in the wrong spot. There may be increased vibration because of this.

DeWALT Handheld Blower Making Rubbing Sound in Blower Fan

You should examine the housing, washers, flywheel, or impeller nut if your handheld blower fan is making a clicking, rubbing, or loud noise.

Using our repair and symptom guide, you can more accurately determine the part that has to be changed and how.

Consult the manufacturer’s manual if your model requires special repair instructions. If, for example, you purchased a larger quality model, you could find the DeWALT 60v blower problems are often the same, yet they take longer to manifest. (Find the Best Battery Powered Leaf Blower)

DeWALT Leaf Blower Doesn’t Blow Air

In most cases, if your blower won’t blow, examine the impeller nut, fan, and tubes.

Your leaf blower instructions may call the impeller a fan. As above, a fan attached to the crankshaft delivers airflow. Your leaf blower’s fan has fins that move air.

Occasionally, rocks and debris can harm these fins, and damaged fins will stop the fan from blowing air.

The leaf blower’s tubes direct air flow: in some models, the tubes funnel air to a nozzle that boosts airflow. However, it can seem that the blower isn’t blowing air or isn’t blowing enough air, and if you have missing or damaged tubes, they cause this.

Some leaf blowers allow you to redirect airflow via the blower housing, allowing it to serve as a vacuum. However, if your blower isn’t blowing air, it may be misconfigured.

Leaf Blower Dies At Full Throttle

A slightly clogged leaf blower air filter can cause the engine to start but die at full power. Over time, dirt can accumulate in the air filter and choke the engine.

As clogged, the air filter let’s just enough air into the engine to idle, but it shuts down when you speed up.

A clogged air filter might also cause a harsh blower operation. Therefore, air filters should be cleaned as part of your regular blower maintenance regimen.

Likewise, a muffler reduces leaf blower engine noise, and a spark arrestor stops engine sparks from starting the blower and igniting.

Leaf blower exhaust gases enter the muffler and spark arrestor through the exhaust port. Over the life of your blower, carbon deposits from the engine exhaust can be deposited in the muffler and spark arrestor screen.

If the exhaust port, muffler, or spark arrestor is clogged with carbon, exhaust gases can’t leave the engine.

This can cause full-throttle engine failure. In addition, deposits can build up over time, so you should clean your muffler/spark arrestor during your tool’s periodic maintenance. (Read Where Are Husqvarna Chainsaws Made)

Do’s and Don’ts of Using A DeWALT Battery

Please use genuine DeWALT batteries to ensure safe compatibility with DeWALT tools and chargers and the best possible performance.

Increase DeWALT Battery Life

As soon as you see a noticeable loss of power from the tool, stop using the battery. A battery could be damaged if it is completely discharged.

To prevent draining the battery, avoid taping the trigger. (this could void your warranty)

The battery is affected by temperature. Batteries won’t accept a complete charge if they are too hot (105°F or above) or cold (below 40°F).

Outside the 40°F-105°F range, charging batteries might cause a permanent runtime loss, shut down unexpectedly, and won’t blow air.

A chemical reaction occurs when batteries are charged and discharged. If the environment is excessively hot or cold, the chemical reaction is disrupted, resulting in a loss in run-time.

Transport carefully. When transporting batteries, fires can be caused if the battery terminals unintentionally contact conductive materials like keys, coins, and tools.

Anytime you transport individual batteries, ensure the battery terminals are shielded and securely insulated from materials that could encounter them and cause a short circuit.

DeWALT Blower Engine Rpm’s Too High

Check the fan, impeller, rod, or governors if the blower motor RPMs operate too high. The major causes of this are listed below.

Broken Fan Blades

Your blower’s fan, known as an impeller, rotates to draw air into the blower and is powered by the motor. Your blower tube directs air through the housing side and pulls it toward the front of the blower.

The fan’s blades can break off in multiple places, increasing the engine’s RPM. Throughout the blower’s lifespan, debris may unintentionally be pulled into the fan blades, which may cause their breaking.

To help prevent this problem, remove debris entering the blower housing. You will need to replace a broken fan as there’s no way to fix it, and it won’t blow effectively until it has been changed. (Read DeWALT 20v Blower Problems)

Broken Impeller

Your leaf blowers impeller is essential to its efficient operation. The impeller rotates to draw air in, at which time it is directed into the blower tube.

Your engine’s RPM may be excessively high because of a broken impeller, typically brought on by debris harming the fan blades and entering the blower housing. Ensure the blower housing is free of debris to lessen the possibility of your impeller blades failing.

Loose Rods

With a vast, wheeled blower powered by a 4-cycle engine, a rod connecting the throttle control to the governor’s arm is present. No of the circumstances, the governor will control the engine’s speed.

To keep the speed, the governor will open the throttle further when the going gets tough.

The governor won’t be able to regulate the throttle if the rod connecting it to the governor becomes damaged or becomes loose. So, your engine RPMs may run too high because of this.

Faulty Governors

A large, wheeled blower (looks like a lawn mower) damaged by a 4-cycle engine may have a broken or incorrectly set governor. Your leaf blower’s governor is made to keep the desired speed constant.

It works with the throttle to manage that speed. Your engine’s RPMs may run excessively high if your governor is set incorrectly.

Higher-than-normal engine RPMs might be caused by a damaged governor or governor’s arm.

We’ve independently reviewed this article to make sure it’s as accurate as we can make it.

To find out more about our article creation and review process, check out our editorial guidelines.

Is your DeWALT battery not charging?

Sadly, I’ve been there too. I know how annoying it can be to have this happen, especially when you’re in the middle of an important project and your tools suddenly lose power.

Luckily, you’ve come to the right place to get this issue fixed.

If your DeWALT battery is dead, try cleaning the contacts, and charging the battery slowly with mini boosts. Connecting it to another battery or compatible AC adapter can also solve the issue.

Read on to learn more about these methods and forget all about the problem!

Ways to Revive Your Dead DeWALT Battery

Before you go tossing your DeWALT battery into the trash, there are different ways to revive it and get more use out of it.

In this article, we will consider 4 ways you can do this. Take a look at them below.

#1 Clean the Contacts

So we’ll start the ball rolling with the easiest method for fixing your DeWALT battery. That is, to check your contacts and give them a good clean.

A thorough cleaning of the contacts is sometimes all your battery needs to start working again. This will save you from having to pull the battery to pieces or turn the garage upside down trying to find your multimeter.

You might need to clean the contacts on your DeWALT battery for the following reasons.

  • The contacts are rusty. The battery will not be able to charge through the rust.
  • The contacts are dirty. They must be clean for the battery to charge properly.

If your contacts are dirty, try this cleaning method:

  • Use a clean rag to wipe over the contacts on the battery and the charger. Completely remove any dirt, dust, or grime from them.
  • Connect the tool to the charger to see if it charges. If it doesn’t move on to the next method.

If your contacts are rusty, do the following:

  • Scrub the contacts gently on the battery and the charger with sandpaper. Do this until they are clear of rust.
  • Connect the tool to the charger to see if it charges.

NOTE: Fine-grit sandpaper between 320 and 400 should suffice for this job.

#2 Charge the Battery Slowly With Mini Boosts

So you’ve cleaned the contacts but still can’t get your DeWALT battery to charge? Then here’s the next method. That is, charging the battery slowly with mini boosts.

But what does that mean exactly?

Charging the battery little by little helps to wake the battery from its slumber. It raises the battery’s charge just enough so that you can then use the charger properly.

If your battery won’t charge normally, it means that the battery is too flat to be safe for charging.

This happens when you use the tool until the battery is almost flat then don’t connect it to the charger for a few days. The following graph explains a little more about what happens when your battery enters sleep mode.

Connecting the battery to a power source for just 2 or 3 seconds at a time slowly boosts the battery. It does so until it is out of the slumber zone.

Ok, so how do you do it? Take a look at the following steps.

  • Connect the battery to a power source for 2 to 3 seconds at a time. After 2 or 3 seconds, disconnect the battery from the power source. You should disconnect the battery just before the lights come on.
  • Repeat step 1 for up to 30 minutes. This should give the battery enough power for you to charge it normally.

Bear in mind that most chargers don’t have an on/off button, you just plug them in. Depending on the specific charger model, it may be easier to unplug it from the outlet rather than removing and reattaching the batteries.

#3 Connect the Battery to Another Battery

This method will help you to pass the charge from a charged battery to your flat battery. This will help the flat battery to have enough power for you to charge it normally.

dewalt, electric, mower, troubleshooting, dead, battery

Ready to get started? Then here’s how to do it.

  • DeWALT battery that won’t charge
  • Another DeWALT battery that is fully charged.
  • Two insulated wires

Do not use any other material, such as scissors, to connect both batteries, as this can cause short circuits, sparks, or even fires if they come in contact with the battery terminals.

Please wear gloves that are made of a non-conductive material and safety glasses. Do not work near any gas vapors.

Once you’ve gathered your tools, do the following.

  • Take an insulated wire and connect one end of it to the positive terminal of the good DeWALT battery. Then, connect the other end of the insulated wire to the positive terminal of the dead battery.
  • Take the other insulated wire and connect one end of it to the negative terminal of the good battery. Then, connect the other end of the insulated wire to the negative terminal of the dead battery.
  • Leave the wires connected for a few seconds.

It is very important to double-check which terminals you are connecting. Positive should be connected to positive and negative to negative. Getting this the wrong way around could cause permanent damage to the battery.

DeWALT Charger Solid Red Light But Not Charging: What to Do?

If you are reading this, then you have a DeWALT charger with a solid red light and it is not charging. This can be very frustrating, but do not worry, you are not alone.

In this guide, we will walk you through the most common reasons why your DeWALT charger is not charging and what you can do to fix it. We will also provide some tips on how to prevent this from happening in the future.

Different DeWALT Chargers May Have Different Colors

If you have a DeWALT charger that has a solid red light, it is important to know that different models of chargers may have different colors for the solid red light. For example, some models will have a green light instead of a red light.

If your charger has a different color light, please consult your owner’s manual to determine what the light color means. [1]

What Do Those LEDs Mean Already?

The light on your DeWALT charger is an important indicator of the status of your battery. When the light is red, it means that the battery is charging. When the light turns green, it means that the battery is fully charged. If the light is flashing red or green, it means that there is an error with the charger or the battery.

If your charger has a solid red light, it means that the battery is charging. If the light is green, it means that the battery is fully charged. If the light is flashing red or green, it means that there is an error with the charger or the battery. [1]

Yellow Led and Temperature Delays for DeWALT Batteries

When the charger is connected to a power source and the battery is inserted, a yellow light will come on. If this light is flashing, it means the temperature of the battery is too low for charging to start. The battery must be warmed up before charging can begin.

To do this, simply remove the battery from the charger and place it in a warm environment for a few minutes. Once the temperature of the battery has risen, reinsert it into the charger and charging will begin automatically.

If the light remains solid yellow, this means that the charger is running a self-test. This is normal and should not cause any concern. The test takes around 30 seconds to complete and the charging process will begin automatically once it is finished.

If the light turns red after the self-test is complete, this means that there is an issue with the charger or the battery and charging will not commence. In this case, you should contact DeWALT customer service for further assistance.

Is that True for All DeWALT Chargers?

No, it’s not true for all DeWALT chargers. In fact, it’s not true for most of them. The vast majority of DeWALT chargers have a green light that comes on when they’re charging and turns off when the battery is fully charged.

The only time you’ll see a red light on a DeWALT charger is when there’s a problem with the charger or the battery. If you see a red light, it means that the charger isn’t working properly and you need to troubleshoot the problem. [1]

DeWALT Battery Electronic Protection System

The DeWALT Battery Electronic Protection System (EPS) helps to protect your batteries from overcharging, overheating, and deep discharge. When the EPS is activated, it will cut off power to the battery to prevent damage.

  • Overcharging: If a battery is left on the charger for too long, the EPS will activate to prevent overcharging;
  • Overheating: If a battery gets too hot, the EPS will activate to prevent overheating;
  • Deep discharge: If a battery is discharged too deeply, the EPS will activate to prevent deep discharge;

How to tell if the EPS is activated:

The EPS will activate if the battery charger has a solid red light. If the charging indicator light is blinking, this means that the EPS is not activated and the battery is charging normally.

What to do if the EPS is activated:

If the EPS is activated, you will need to replace the battery. You can find replacement batteries at your local DeWALT retailer.

You should also check the charging indicator light on the charger to make sure that it is not blinking. If the light is blinking, this means that the EPS is not activated and the battery is charging normally.

Is Something Defective with Your DeWALT Charger or Battery?

If your DeWALT charger has a solid red light but is not charging, it could be due to a number of reasons. In some cases, it may be necessary to replace the charger or the battery. However, there are also a few things you can try first that may fix the issue without having to replace anything.

If the cord is plugged in securely and there are no obstructions, the next thing you should check is the charging port on the battery. Make sure that there is nothing blocking the port such as lint or dirt. If the port is obstructed, it may not be able to make a good connection with the charger.

If you have tried all of the above and the charger still is not working, it is possible that there is a problem with the charger itself. In this case, you should check for updates. DeWALT offers firmware updates for its chargers from time to time. These updates can fix bugs and improve performance.

If you have tried all of the above and the charger still is not working, the next step is to contact DeWALT customer service. They may be able to help you troubleshoot the problem or offer a replacement charger or battery.

  • Contact DeWALT customer service. If you’ve tried all of the above and your charger still isn’t working, you may need to contact DeWALT customer service for further assistance;

Troubleshooting a DeWALT charger that is solid red but not charging can be frustrating, but following these steps should help you get to the bottom of the issue

If your charger is still not working after following these steps, contact DeWALT customer service for additional help. [1]

DeWALT Charger Solid Red Light but Not Charging: What to Do?

By following these simple troubleshooting steps, you should be able to get your DeWALT charger working again in no time. [2]

DeWALT Charger- Briefly Explained

DeWALT is a popular charger used to charge up batteries for tools. It is known to have a long life and be very reliable. However, like any other charger, it can have problems from time to time. One such problem is when the DeWALT charger has a solid red light but is not charging the battery.

There are a few things that could be causing this problem. It is important to troubleshoot the charger to determine the root of the problem. Once the root cause has been determined, it will be much easier to fix the charger and get it working again.

One possible reason for a DeWALT charger to have a solid red light but not charge the battery is that the battery is not properly connected to the charger. This can be easily checked by making sure that the battery is properly seated in the charger and that the connections are tight.

Another possible reason for a DeWALT charger to have a solid red light but not charge the battery is that the charger itself is not working properly. This can be checked by testing the charger with a different battery. If the charger works with the other battery, then the problem is most likely with the first battery and not the charger.

If neither of these solutions solves the problem, then it is likely that there is a more serious issue with the DeWALT charger. In this case, it is best to take the charger to a qualified technician for further diagnosis and repair. [1]

DeWALT Charging Lightning Patterns

Most DeWALT power tools come with a charger that has a built-in LED light. This light is used to indicate the charging status of the battery.

There are usually three different colors that the light will be, depending on the state of charge of the battery. The three colors are green, yellow, and red. Here is what each color means:

  • Green: The battery is fully charged and can be used;
  • Yellow: The battery is charging and will be ready to use soon;
  • Red: The battery is not charging and will need to be replaced;
  • The battery may be defective. If this is the case, you will need to replace the battery;
  • The charger itself may be defective. In this case, you will need to replace the charger;
  • There may be something wrong with the power outlet that you are using. You will need to check to make sure that the outlet is working and that there is nothing blocking it;
  • The battery may be too hot or too cold. If the battery is too hot, it will not charge. If the battery is too cold, it will also not charge. You will need to let the battery warm-up or cool down to room temperature before trying to charge it again;
  • The battery may be too old and no longer able to hold a charge. In this case, you will need to buy a new battery;

If you have a DeWALT charger that is not working, you can try these troubleshooting tips. If none of these tips work, you will need to contact customer service for further assistance.

Electric Lawnmower Left Out In Rain (What to Do)

For some time now I have been looking at buying an electric lawnmower. I don’t need it, really. I just want one. One issue I’ve run across, however, is that people have left them out in the rain and have wondered if they it. Like any other electric tool, an electric lawnmower doesn’t do well with exposure to water. I’ve been reading up on this and here’s what I’ve learned.

Here are 3 steps that you should take if you left your electric lawn mower out in the rain:

  • Take apart your lawnmower to expose the motor.
  • Get the motor and wiring as dry as possible.
  • Apply electric contact cleaner
  • If your motor wiring has lost insulation resistance, use a megohmmeter to test and reestablish the resistance of the wire windings around the motor shaft.

Whether you have an electric push mower or one of those really cool robotic mowers like the WORX Landroid (link to Amazon), you’ll want to keep it out of the rain as much as possible. However, accidents can and do occur.

Check out the DynaTrap Mosquito Flying Insect Trap – Kills Mosquitoes, Flies, Wasps, Gnats, Other Flying Insects – Protects up to 1/2 Acre (link to Amazon).

If you act quickly, you can often prevent a rain-soaked electric lawn mower from being irreparably damaged, so you need to know how to dry it out correctly.

How Electric Lawn Mowers Are Designed

Because of its sensitivity to moisture, your lawnmower’s motor will be housed inside a water-resistant casing that’s likely made of plastic or metal. Despite this. an electric mower isn’t, by any means, impervious to water damage from being left out in the rain.

Often, these cases are designed with vents that allow air to flow in and out, which helps keep the electric motor from overheating while in use. These openings also allow water to reach the lawnmower’s protected motor and wiring if it’s exposed to rain for long periods.

The battery casing is also made to be water-resistant, but, to allow the battery to be removed and replaced, the covering sits on a hinge that allows the compartment to be open. Gaps in connection can eventually allow water through that can damage the battery as well.

Beyond just the damage water can do to the motor, excess moisture will also cause the battery connectors to corrode, which interrupts the energy supply from the battery to the mower’s motor.

As a result, the lawnmower with either run with diminished power or may not turn on at all. Make sure as soon as you realize your lawnmower has been caught in the rain that you start the drying process.

How Condensation Can Damage Your Electric Mower

Exposure to rain isn’t the only way that the elements can cause water damage to your electric lawnmower.

Even if you live in an area with little rainfall, widely fluctuating temperatures can result in similar issues. As the temperature drops as night, water can easily condense on the underside of the water-resistance casings around the motor and battery.

To best protect your electric lawn mower’s longevity, make sure to always store it in the garage to minimize the risk of condensation-related damage.

If that’s not an option in your home, you can purchase a weather-resistent shed (link to Amazon) to store your lawnmower and other electrically-powered tools that would have the same problem.

Another thing to keep in mind is the condition of the grass when you use your lawnmower. Your owner’s manual will have the most specific recommendations for your model.

A good rule of thumb is to never mow the grass with an electric lawn mower if you can step on the grass and leave a footprint behind due to the wetness of the grass.

How Water Damage Affects An Electric Mower’s Wiring

Once water or moisture has accumulated on your motor, it can seriously undermine the intended function of its wiring and power delivery.

That’s why it’s so important that you avoid mowing wet grass. If the power interruption occurs while the lawnmower is in use, you can risk electrical issues and personal safety.

Electric lawnmowers use electrical energy from its power source (the battery) to generate mechanical energy via the rotation of its motor (source). The wiring that transfers electricity to the motor is usually made from copper and is wrapped around its center column.

These wires are insulated to protect against short circuits, but when they come into contact with a lot of water or repeated exposure to moisture, the insulation becomes ineffective.

Then, a short circuit of the power occurs, which means that electricity is diverted from where it’s supposed to go within the mower.

Fortunately, if your lawnmower was simply left in the rain, there’s no risk of handling it unless you turn it on. You’ll eventually need to do so as part of the repair process but you’ll have an opportunity to dry it off first.

How a Short Circuit Can Damage the Motor

As short circuits often result in an excess amount of energy being routed to the wrong place in the electrical system, water exposure can result in significant damage to your lawnmower’s motor (source).

The excess current will cause the parts to overheat if the lawnmower is turned on in this condition.

This can even result in white smoke being produced if the lawnmower is run as the high amounts of electricity sent into the motor will cause it to burn, especially if your lawnmower model has a brushed motor.

The smoke is generated because parts of the motor are being burned by the excess, diverted electricity, which can result in harmful fumes as well as a potential electrical fire or electrocution if the mower isn’t turned off.

If you are concerned that your electric lawn mower has been exposed to water or high levels of moisture, do not turn it on to check how it operates.

How to Initially Dry Your Lawn Mower

To salvage your electric lawn mower after leaving it in the rain, you’ll need to get the motor as dry as possible immediately. This can be accomplished in a few different ways, including using compressed air, a blow dryer, or a fan to air dry and blow away remaining moisture.

Refer to your owner’s manual to see how you can remove the water-resistant casing around the motor and expose it for you to dry off.

Drying out the motor won’t necessarily be a simple task, especially if your mower was in the rain for a long time.

In some cases, it might be best for you to leave your motor out to dry. The drying process can take up to 8 hours or more.

Additionally, if your lawn mower’s wires have become wet enough to weaken its insulation, you need to use a device called a megohmmeter (link to Amazon) to measure the current resistance of the outer coating on the motor’s wiring.

This will tell you whether you need to take further steps to dry the wiring based on the readings.

Apply Electric Contact Cleaner

After leaving the mower to dry, it’s a good idea to disconnect the battery and apply an electronic contact cleaner like BW-100 (link to Amazon) to the connection terminals and any other electrical connections. You can use grease or lubricant if you prefer. You just want to make sure that connections are clean and moisture-free.

How to Restore the Insulation Resistance of the Wiring

After you’ve got your lawn mower’s motor and wiring rid of most excess moisture, you will need to restore the motor wiring’s insulation resistance to make it safe to use again.

If you are not familiar with insulation resistance and how a megohmmeter works, I suggest you watch this YouTube video that takes time to fully explain this.

Lawn Mower Grass Catcher Troubleshooting

Stopping every 5 minutes to clear the underside of the mower isn’t much fun! Grass catcher problems can be so annoying.

Troubleshooting a lawn mower grass catcher? Common grass catcher problems like clumping, clogging, uncut grass, and a grass bag that won’t fill are caused by:

In this guide, I will cover all the most common grass catcher problems and their solutions.

Very often, a bad or blunt blade is the root cause of bagging issues. Sharpening or replacing a worn blade will improve bagging performance.

If you need more help, check out the “Blade sharpening video.”

The sharpening video covers safely sharpening the blade both on and off the mower. It also includes balancing the blade and torquing the blade bolt to specification.

What Is Mulching?

I live in Ireland, and it rains a lot; sometimes, it rains persistently, and if you need to cut grass, then you have to cut wet grass. Grass chute clogging is usually caused by cutting conditions but is also commonly caused by a worn cutting blade.

The blade is the business end, and it needs to be in tip-top condition.

Chute – A clogged chute can, of course, be a symptom of an underlying problem. So clearing the chute may not solve the problem. Check the chute for damage or old dry grass build-up.

Clean – Old grass on the deck can cause problems. Regular cleaning will prevent build-up and prolong the life of your mower.

Sharpening – A sharp blade will solve lots of cutting and collecting issues.

Wet Grass – It’s much heavier than dry grass, obviously, and won’t be thrown as far into the grass bag/box by the laboring engine. It also sticks to the underside of the mower, causing clogging and preventing the grass catcher from filling. Mowers don’t cut damp/wet grass very well, especially if it’s tall.

Height – How about the cutting height? It may be set too low. I know this sounds obvious, but try lifting the deck height, and if you want a tighter cut – drop the deck and cut again. Ideally, your mower shouldn’t be cutting more than an inch of grass; ask it to do more, and cut quality suffers.

Try cutting more regularly, and keep your mower deck clean and free from dry grass. Consider coating the underside of your deck with Teflon Non-Stick coating; it helps reduce grass clogging.

Tallgrass – Tallgrass is hard on a mower, especially if you’re asking it to cut the lawn tight with just one cut. Tallgrass will cause the mower to clog.

  • Option 1 – Quick fix is to spray the deck with WD40; it does help, but it won’t last.
  • Option 2 – Spray deck with DuPont Teflon coating.
  • Option 3 – Spray the deck with bed liner, my preferred option. Works on tractors, riders, and walk-behind mowers.


As you know, mulching blades chop grass very finely and drop it back onto the lawn, where it helps feed the lawn. Mulching blades are designed specifically for this task, but they can cause lots of clogging problems, especially if the grass is long or damp.

Mulching blades just don’t move grass efficiently because they’re not designed to. They work best when the grass is cut dry, regularly and in small amounts.

Mulching Blades aren’t designed to collect.

Mulching tall wet grass won’t work; the blade is designed to cut just small amounts of grass at a time.

Hybrid Mulching Blade

As you know, a true mulching mower doesn’t collect; its function is to finely chop and drop the clippings. This type of cutting is convenient; it’s a lot less work than emptying a grass bag, which gave mower manufacturers an idea.

The Hybrid Blade (3 in 1) – a mower blade that does it all, collects, mulches, and discharges. Well, it does an OK job, but if conditions become challenging, the quality does suffer, especially if conditions are wet.

The complaint I hear most with the 3-in-1 mulching blades – won’t fill the grass catcher. The solution – remove the mulching blade and fit a lift blade.

If you don’t want to mulch, change your blade for a lift blade; you will eliminate lots of clogging, clumping, and half-filled grass bags.

3 in 1 – The Hybrid mulching blade is kind of ok at everything.

The lift blade is also known as the 2 in 1, so-called because it bags and discharges. The lift blade vacuums the grass upright before cutting and moving clippings to the bag.

They’re designed for collecting grass and are available in low, medium, and high lift. A higher lift blade will require a more powerful engine. The lift is created by curving upwards of the trailing edge of the blade. The higher the lift, the better the bagging. If you love bagging – You need a lift blade.

Honda 3 in 1 – The Honda Hybrid mulching blade is the best in the business. Unfortunately, it can’t be fitted to other mower makes. The reason the Honda is so good at mulching and collecting – twin cut blade setup. Twin stacked blades working together allow blades mulches and move the clippings. Smart!

Grass Bag Won’t Fill

A grass bag/box that doesn’t fill has a few likely causes. The obvious ones: are clogged chute, thatched grass bag, damaged or worn blade, insufficient throttle, and poor engine performance.

How to fix a battery #dewalt#batterysave #diy

Thatched – A thatched grass bag is a common problem. Mowers often get cleaned at the end of the season (well, some do), but bags rarely do. Examine your bag/box as a guide; when held to the light, you should be able to see through it. If the air can’t pass through the bag, then grass won’t be carried into the bag.

A stiff brush will remove the old thatched grass, or better, use a power washer. Cleaning – Stiff brush or a power washer does the job.

Chute Clogs – A clogged chute can be a symptom of an underlying problem. So clearing the chute may not resolve the issue. Check the chute for damage or old dry grass build-up. Grass build-up or damage to the underside of the deck can cause the grass to catch and clog.

Deck Coating – The underside of the deck should be smooth so that the grass moves freely around the deck, up the chute, and into the bag. DuPont makes a Teflon Non-Stick coating which helps reduce grass clogging.

Cleaning – Move your mower to a suitable location, as it leaves a bit of a mess. Just attach and turn on the garden hose. Start your mower to engage the blades.

Why The Grass Trailings?

Grass trailings are commonly caused by a poorly fitting or damaged grass catcher. If you find your grass catcher is damaged, consider buying a new one, they’re available to purchase with or without the metal frame.

Check if the bag/box sits correctly against the mower body. If it’s loose or damaged, the air and grass flow to the bag is compromised.

If all is well with the grass catcher, go ahead and replace your blade.​

Trailings are really annoying; check the bagger is closing snugly.

Check For Blade Damage – A defective blade can cause vibration, uneven cutting, and poor grass collection. Examine your blade, checking for damage, misalignment, or bent or broken trailing/leading edges.


Blades need to be kept sharp. I recommend about twice per season or more, depending on the terrain. Obviously, if your blade is dull, it can cause all sorts of problems, including blocked chute and grass catcher issues. Check out blade maintenance tools here; they make the sharpening process a ton easier.

And if you need a video on the process, it covers it here, sharpening blade on and off the mower.

Impact – When blades hit something hard, well, you know! The damage causes vibration and all sorts of cutting issues.

Bent – Bent blades can’t be repaired; just go ahead and replace them.

What Is PTO Slip?

The blade clutch or PTO (Power take-off) won’t be fitted to all lawn tractors, but it’s easy to locate; it lives right under the engine. A clutch system isn’t common on walk-behind mowers, but Honda and Toro offer them on the higher-end models.

It may be manual or electric; either way, its job is to lock the engine crankshaft to the blade deck pulley when you engage the blades on a button or lever. The clutch, like a clutch in a car, will wear out, and when it does, it causes the connection between the engine and deck to slip.

Symptoms include poor grass collection, uncut grass, and sometimes a burning smell.

PTO – Check the PTO system. The manual version is engaged by a cable. It lives on the crankshaft, right under the engine. Check that the cable is pulling the PTO lever all the way.

Fitting – Replacing the PTO isn’t difficult, but air tools would make it really easy.

Check Deck Belt Condition

Belt wear is also a common reason for a chute to clog; check the deck-cutting belt for damage and general wear tear. A new belt will transfer more of the engine power to the cutting blades and will improve the cutting and bag filling performance.

Belt types and lengths will be specific. Some brands will only work well using OEM (Original Equipment Manufacturer) belts; check out “Mower belt replacement.”

If you need walk-behind or ride-on mower blades, bearings, sharpening tools, etc., check out the link below.

Worn – A cutting deck belt that’s slipping will be less efficient at collecting.

Check the belt for proper tension, cracking, glazing, or contamination.

Damaged – Damaged belts will cause vibration and poor general performance.

A typical deck belt might last 4 – 5 years.

Check Engine Performance

It’s also worth considering, is the throttle set correctly? It should be set to fast/run when cutting. Is the engine running as it should? If the engine power is reduced, the mower may still cut well but will be less efficient at collecting.

A small-engine tractor or walk-behind mower should have a tune-up at the beginning of every season, regardless of how well it might be running.

Belt types and lengths will be specific. Some brands will only work well using OEM (Original Equipment Manufacturer) belts; check out “Mower belt replacement.”

Bad Gas

Old fuel is the number one cause of poor engine performance, use a gas stabilizer over the winter to help protect your lawn mower carburetor; check out “Carburetor troubleshooting.”

Tune-up – Mowers like a tune-up at least once per season.

Related Questions

How does grass catcher work? A grass catcher works by collecting the grass that is thrown into the bag by the force of the mower blade wings. The grass catcher works best when the walls of the bag/box are clear so that the forced air from the blade can pass through it quickly.
