Electric mower wont start. Lawn Mower Won’t Start (Why How to Fix)

Lawn Mower Won’t Start (Why How to Fix)

A lawn mower that won’t start can be baffling, especially if you don’t know much about engines. Most people learned the workings of the combustion engine in high school during science class. Vague memories of Nicolaus Otto’s 1876 early engines certainly won’t help get your lawn mower up and running again. So, instead of digging out an old high school textbook to find a solution, let me share with you the most common reasons why your lawn mower’s engine won’t start.

Why Your Lawn Mower is Not Starting (The Short Answer)

The most common causes for a lawn mower not starting usually stem from problems with the starter system (the battery), the fuel delivery system (the fuel pump), the air intake, and the ignition spark (the air filter and spark plug). A dirty carburetor or safety system can also prevent a mower from starting.

Possible Reasons Why Your Lawn Mower Won’t Start

I’m pretty sure that by the time you get to the bottom of my list, you will have found the reason why your lawn mower isn’t starting. So, let’s take a look at the possible causes.

Dead Battery

The first place to start is at the battery. Riding mowers, zero turns, and a few walk-behind lawn mowers use a starter motor and a battery to fire up the engine.

If your battery isn’t fully charged or is dead (I wrote about symptoms of a bad/dead lawn mower battery here), then the starter motor won’t be able to crank over the engine.

If you have a battery tester, you can check the volts of the battery and the cold cranking amps. Alternatively, you can have the battery tested at an auto parts store.

Bad Spark Plug

Old or damaged spark plugs cannot provide a spark inside the cylinder required to ignite the fuel vapor from the carburetor. No matter how many times you try to start the engine, if the plug is bad, the engine just isn’t going to start.

How do you tell if a spark plug is bad? You test it. When I need to test a spark plug, I like to use an inline spark plug tester. This is a little device that can be fitted in seconds and sits between the spark plug and the ignition cable. With the tester installed, you just need to crank the engine with either the key or pull cord and check to see if the tester lights up.

Alternatively, you can remove the spark plug and crank the engine. As long as the spark plug is connected to the ignition cable and touches a metal part of the mower, you’ll see a spark when you crank the engine if the plug is good.

Blocked Air Filter

The air filter is the one defense the engine has to stop any debris from entering the engine when it draws air into the carburetor. This specifically designed filter allows a certain amount of air into the engine during operation.

Once the air filter becomes blocked or dirty, the air getting into the engine is decreased, resulting in the engine not starting, poor performance, and stalling.

To check the air filter, you’ll need to pop off the air filter housing cover and remove the filter. Once the filter is removed, you can check it to see how blocked or dirty it is.

Blocked Fuel Filter

Like the air filter, the fuel filter is a protective measure the engine uses to stop dirt from entering the engine. Rather than filtering air, this filter removes any debris and impurities from the fuel.

Once the filter becomes clogged, it no longer allows fuel to flow through the fuel system, and the engine becomes starved. An engine that is starved by a clogged fuel filter is not going to start.

You’ll find the fuel filter located between the fuel tank and the fuel pump. Usually, these are small see-through devices that you can inspect visually.

Once you find the filter, you’ll want to see if it’s dirty. If it looks like it has a bit of debris or has turned black, then you’ll know you need to replace your fuel filter as it’s probably stopping your engine from starting.

Broken Fuel Pump

The fuel pump is the device that transfers the fuel from the fuel tank to the carburetor. Mower fuel pumps rely on a diaphragm, spring, and a vacuum from the engine.

It’s common for debris to enter the fuel pump and clog it up. If a lawn mower fuel pump is not working properly, it will starve the engine of fuel and result in your mower not being able to start.

A quick way to test a lawn mower’s fuel pump is to remove the outflow pipe from the pump and crank the engine. Once you crank over the engine, fuel will spurt from the fuel pump. If it’s broken, then no fuel will come out, and you will have pinpointed your problem.

Blocked Fuel Cap

You would think that such a simple thing as a fuel cap can’t stop a mower from starting, but it really can.

You’ll notice that on the top of a mower’s fuel cap, there is a tiny hole. This hole allows air to enter and exit the fuel tank. If your lawn mower’s gas cap is not venting (i.e. this hole becomes blocked), a vacuum can build in the fuel tank, preventing gasoline from flowing through the fuel system.

So pop off the fuel cap and take a look at the hole. If you find that it is blocked, more than likely from yard dirt, then it’s probably the reason why your mower is not starting.

Dirty Carburetor

If you have checked off all the other items on this list, then your mower’s problem likely comes down to an issue with the carburetor.

The carburetor has a small jet inside which vaporizes fuel so that it can be ignited in the cylinder head. Contrary to popular belief, liquid gasoline doesn’t burn; it’s the fumes from gas that do.

So, if this tiny jet becomes blocked, which is common if bad fuel or junk gets into the carburetor, it can no longer create the vapor needed to start the engine. The only way to check for a dirty jet is to remove the carburetor and inspect its interior.

Safety System

Finally, one part of the mower that gets overlooked is the safety features designed to stop the mower from starting. This isn’t a result of a malfunction but a feature that keeps you out of danger.

The seat, the brake, the blade engagement button (these apply to riding mowers), and even the bail lever are all systems that stop the engine from starting.

So, if you’re unsure of your mower’s correct starting procedure, grab the manual or look online at the manufacturer’s website for the proper method.

Electrical Lawn Mowers

It’s not only gas-powered lawn mowers that have problems starting; electric mowers, both battery and corded, can suffer from their own specific issues. Here are a few common problems that can stop your electric mower from starting.

Damaged Cord

Corded electric mowers have a long cable connecting the mower to the power outlet. These cables can take a real beating when dragged around the yard.

The easiest way to check the cable is to inspect it visually. Alternatively, you can use a multimeter to test the voltage coming out of the cable once it’s powered up.

Poor Electrical Connections

The connection on an electric lawn mower often suffers from some corrosion. This is usually due to the damp conditions the mower spends a lot of its time in.

The connection may be located where the battery/cord connects to the mower or, more commonly, where the cable connects to the electric motor.

By removing the mower’s cover, you’ll expose the electric motor. Here you’ll be able to see if the terminals are corroded and causing a problem with the lawn mower starting. Alternatively, you can use a multimeter to test the connections.

Worn Out Brushes

Electric motors require power to be transferred from the terminals/stator outside to the spinning rotor inside. To do this transfer, electric lawn mower motors use spring-loaded brushes that rub against the spinning internal rotor.

With the friction of the spinning, the brushes wear down and need to be replaced. This is really the only servicing an electric lawn mower requires.

Once you have access to the motor, you should be able to pop out the brushes by removing the terminal mounting screw. With some motors, you don’t even need to do this since the brushes are just clipped in for easy removal.

Once you have the brushes removed, you can inspect them to see if there is enough length left to make contact with the rotor. They are usually marked, showing when they need to be replaced.

How to Fix a Lawn Mower That Won’t Start

So, was I right–did you find the reason why your lawn mower won’t start? Now let me explain how you can get it fixed.

Charging the Mower’s Battery

Charging your lawn mower’s battery can be done in a few different ways. If you have an old charger, then you’ll need to disconnect the cable from the lawn mower. You can leave the battery connected if you have a modern Smart controlled charger.

To disconnect the battery, a small wrench set will do just fine. Just remember that you disconnect negative, then positive, and then connect, positive then negative.

Next, you’ll need to set your charger setting. This tells the charger the battery’s voltage and specification, such as lead acid.

Both types of chargers will tell you when the battery is charged, but not all chargers will switch off. So, make sure you know how your charger works before you use it.

How long does it take to charge a lawn mower battery? That will depend on the type of battery you have, the battery’s voltage, and the charger you’re using.

Tools Required to Charge Your Lawn Mower’s Battery

Replacing the Spark Plug

To replace the spark plug on your lawn mower, you’ll first need to remove the ignition cable attached to the existing spark plug.

Next, use your plug wrench to remove the existing spark plug and set it to one side. Now insert the new spark plug into the lawn mower.

There should be no reason to test the gap on your new spark plug, as it should have already been gapped correctly.

Next, with the new spark plug loosely threaded back into the engine, use your plug wrench to tighten the new spark plug snuggly. Finally, reattach the ignition cable, and you are done.

Tools Parts to Replace the Spark Plug

Replacing the Air Filter

Unclip and remove the air filter cover the same way you did when inspecting it, and set it to one side. Next, remove the old filter/s and discard them in the trash.

Now use a cloth to give the inside a good wipe down. If it has some old oil and gasoline residue, then you can use a little WD-40 to help remove the grime. Then check your new filter/s and see if they need to be oiled.

Specific oil helps keep the filter supple and stops them from drying out and cracking. However, oil shouldn’t be used on paper filters, only on sponge filters. If your filter/s does need to be oiled, then you can use a can of spray filter oil to complete this stage.

With the air filters prepped, you can go ahead and insert them into the lawn mower’s filter housing. Finally, reattach the filter housing cover, and the fix is complete.

Tools Parts to Change the Lawn Mower’s Air Filters

Replacing the Fuel Filter

Installing a new lawn mower fuel filter isn’t difficult. First, you’ll want to switch off the fuel using the fuel cut-off valve. This is to stop the fuel from flowing out once the filter is removed.

Next, grab yourself a pair of pliers and remove the spring clips holding the fuel lines to the fuel filter. You just need to slide them down the fuel line, so they no longer rest on the filter.

Then twist the filter while holding the fuel lines. This helps loosen the lines from the filter. Once the filter no longer grips the fuel lines, you can go ahead and pull off both fuel lines. Just be careful as a small amount of fuel will come out of the filter and line.

Next, reattach both fuel lines to your new fuel filter. You’ll notice an arrow on the side of the filter stating the direction the fuel flows in, so make sure to install the filter in the correct fuel flow direction.

Then use your pliers to reposition the spring clips so that they sit over the lines and the filter and grip everything in place.

Finally, switch the fuel back on to test the mower. It will take an extra few pulls to get fuel back through the system and fill the new filter.

Installing a New Fuel Pump on a Riding Mower

Lawn mower fuel pumps vary as there are a number of different designs, but the principle is the same. So, here I want to talk you through a standard fuel pump that is connected to an OHV, which most riding mowers and zero turns have.

First, turn off the fuel cut-off valve to prevent fuel from leaking from the fuel lines once you remove them. So, locate the fuel pump and remove the spring clips from the three pipes. To do this, use a pair of pliers and slide the clips down the pipes.

Next, slide off the three pipes from the fuel pump. So that you don’t confuse which pipe is which, use a marker pen and number them 1, 2, 3, then do the same on the old pump.

Then you want to use your socket wrench to remove the two bolts that hold the pump to the mower. Once the bolts are removed, you can go ahead and remove the old pump.

Position the new pump on the lawn mower and insert the bolts you previously removed. Use your socket wrench and tighten up the bolt nice and snug, but not too tightly as these pumps are usually made of plastic and can crack.

Once the new pump is mounted, attach the three pipes using your marked numbers as a reference and slide the spring clips back into the correct position. If you look closely at the pipes, you should see some indent from their original position.

After completing this step, you can switch the fuel back on and start the mower. A few extra cranks will be needed to get the fuel back through the system.

Unclogging the Fuel Cap

To unclog a fuel cap, you just need to poke the hole with a pin or needle, whichever you have at hand. Use whichever tool you select, push it through the hole, and dislodge the dirt. There probably isn’t going to be much, just enough to cause a problem

Tools Parts to Unclog a Fuel Cap

Replacing the Carburetor

Cleaning a carburetor is a task that not everybody will want to undertake. But if you’re up for the task, I’ll cover how you can swap your old one for a new one. Depending on the particular engine, replacement carburetors start at about 30.

Removing the Lawn Mower’s Old Carburetor

First, remove the air filter cover and filter and set them to one slide. Then, use your socket wrench to remove the couple of bolts holding the back plate of the air filter housing to the mower. These bolts also pass through the carburetor and hold it in place, so once the bolts are removed, the carburetor will be loose.

Next, switch off the fuel using the fuel cut-off valve. Then, use your pliers to remove the spring clip holding the fuel line onto the carburetor. With the clip removed, you can pull off the fuel line.

Next, you’ll need to remove the governor/throttle linkage from the carburetor. To do this, twist them out of the brackets with a bit of persuasion. This was the last thing holding the carburetor to the mower, so now that it’s fully disconnected, you can set it to one side.

Install the Lawn Mower’s New Carburetor

Now it’s on to installing the new carb. Hopefully, the new carburetor came with two new gaskets– one that sits between the carburetor and the engine and another between the carburetor and the air filter back plate. If it didn’t, you need to salvage the old ones as long as they are still in good condition. If they are worn or damaged, you’ll have to get replacements.

So, you’ll need to first attach the governor/ throttle linkage to the new carburetor. Then, attach the fuel line and position the spring clip. Now thread your bolts through the air filter back plate, the gasket, the new carburetor, the second gasket, and finally into the engine. Repeat this with both bolts and make sure to get everything in the correct order.

The last job is to tighten the bolts and reinstall the air filter and cover. That’s it – see, it’s not too difficult. With the new carburetor installed, you can switch the fuel back on and crank the engine.

Electric Mower Fixes

That’s the gasoline powered mower out the way. Now we can move on to the electric mowers. If your electric lawn mower doesn’t start, let’s see if these fixes can get it working again.

Replacing the Cord

Replacing the cord on an electric mower is as simple as it sounds. There’s not much you can do with a damaged cord. You could try to repair it, but this will mean you have to cut a section out, and the cable will get shorter. So, I recommend replacing it with a new one.

Cleaning the Connections

First, remove the connectors from the terminal. Then take some sandpaper and run it over the corroded surface. Once you have removed most of the corrosion, spray the metal area with some contact cleaner. Give the cleaner a minute to soak in, then brush it with an old toothbrush.

Next, use a cloth to wipe down the area you have been working on. Once you are happy with the outcome, repeat the process to include the connector and the terminal. When complete, you can reattach the connector to the terminal. If you find the connector is a little loose, try to give it a little pinch with a pair of pliers.

Finally, make sure everything is connected correctly and that everything is dry.

Tools Parts to Clean Electrical Contacts

Changing the Brushes

The last item on my list is changing out the bushes on your electric motor. While most electric mowers allow you to change brushes, some don’t. So, if your lawn mower gives you the option to change them, then this is what you’ll need to do.

First, remove the mower’s cover and expose the top of the motor. A screwdriver should be enough to remove the top. Then you’ll need to remove the old brushes. If you have ones that are just clipped in, you can unclip them, slide out the old ones, and slide in the new ones. For the rest of you with replaceable brushes, you’ll need to remove the terminals.

Use your screwdriver to remove the screw holding the terminal in place. Once this is removed, you should be able to slide out the old brush and slide in the new one. You need to repeat this for both the positive and negative terminals. With the new brushes installed, reattach the terminals and replace the cover.

Lawn Tractor Won’t Start No Click – Fix it now!

Before we assume there’s a problem, let’s take a minute to check that we’re following the correct starting procedure. All mowers will have safety sensors fitted, and if the sensors are open, they won’t start.

So why won’t your lawn tractor start, not even a click? The most common reason for a no start, not even a click sound, is a totally flat battery, but other likely causes include:

A tractor mower won’t start if the blade lever/button is on, manual mowers need to be in Neutral gear, and some mowers won’t allow starting if the oil level is low or the hood is open.

If you are in any doubt about the correct starting procedure for a lawn tractor, check out – “How to Start Husqvarna Ride-on Mower.”

If you do hear a click sound when you turn the key, check out – “Mower Wont Start Just Clicks.”

Check Battery Connections

To test a battery, you need a voltmeter, but if you don’t have one, try this basic check. If your mower has hood lights or dash lights, go ahead and turn them on. If they light up and are bright, your battery is most likely not the problem.

Dash Lights are Dim

Check – Check the battery cables; they should be clean and tight. When connections are loose or corroded, it prevents available power from flowing to the starter.

Charge Battery – If your battery is completely flat, it will take a couple of hours and will require a battery charging hack, or check out this Smart battery charger the NOCO Genius1 on Amazon.com.

Jumpstart Mower – This is the fastest solution, but it may not be the long-term fix. (see Jump starting below)

Battery Check Hack

• Turn on the lights to check for power supply
• If they work – the battery is likely OK
• If lights are dim – check battery cables
• If cables clean and tight – charge battery
• If you have no lights – check battery with a volt meter

Volt Check – Need a voltmeter for this test. Check b attery voltage – 12.65v is 100%, 12.30v is 70%, and 12.05v is 50% charged. This battery needs a charge.

Very low volts indicate the battery is likely faulty, and it may not recharge. To test a battery, it must be charged, so a battery charger may be required. However, it is possible to jump-start the mower (see below), and given time, the mower’s alternator will charge the battery, assuming it isn’t faulty.

Once the battery is sufficiently charged (about 70%), try the crank test.

Battery Crank Test – Attach the Voltmeter and crank over the engine; if the volts read less than nine, replace the battery. (The battery must be over 70% charged for running this test)

Check out the Amazon link below for quality mower batteries delivered to your door.

Voltmeter – If the lights don’t work at all, you’ll need to use a voltmeter to check the battery’s state of charge. You may have blown a fuse (see below).

If you have very low volts, the battery is likely faulty. The average life of a battery is four years, more if well cared for.

Jumper Cables

If you don’t have a charger, you can still get it running, but you’ll need a set of jumper wires, and a car or any 12-volt battery will do the job. Follow this link for a more detailed guide to Jump Starting.

Jumpers – Use good quality jumpers.

If you are unfamiliar with jump-starting, you’ll find a complete guide here, “Jump starting riding mower.”

Add the cables in sequence 1, 2, 3, and 4 to start the mower, and while idling, remove jumper cables in reverse order 4, 3, 2, and 1.

Dash Lights Don’t Work

Main Fuse – If the battery is fully charged and still no go – check the main mower fuse. Some mowers will have the blade-type fuse; others will have the old-style bottle type.

When the fuse blows, all power is lost; changing it is simple. It is important to replace the fuse with the correct amp rating. If the fuse keeps blowing, the rating is too low, or there’s a short-to-ground wiring fault.

Fuse Location – Places they like to hide include under-seat, under the hood, behind the fuel tank, and control module incorporated. Modules are usually under the dash panel.

Replacing the fuse is simple, just pull out the old one and push the new one into place. It’s important to replace it with the correct amp rating. Otherwise, you can damage the wiring circuit and components.

Check Safety Sensors

Riding mowers are designed with safety features built in to protect us from operator error or accident. Safety features on mowers are controlled by sensors/switches, and most modern mowers will wire those sensors into a control module.

The sensors are a very simple on/off switch type and rarely give trouble; it’s more common for the striking plate that pushes on the sensor to be misaligned; when this happens, the sensor is open, and the engine won’t start or stops depending on where the sensors fitted.

Over-riding – Sensors can be overridden for test purposes, remove and join the wires, and some sensors are wired in reverse – meaning, just disconnecting them will override the sensor. You can check sensors for continuity using a voltmeter.

Starting Procedure

As you know, there’s a starting procedure that must be followed before your mower will start. You can check out the starting procedure here – “How to Start a Husqvarna Ride-on Mower.”

There are several sensors that must be engaged; the location and number of sensors are dependent on the make of the mower and differs between manual and hydro-static (type of transmission).

The main sensors are the brake pedal; seat; gear lever; blade engage control switch or lever, and some models, such as John Deere, will have one fitted to the hood (Hood open – no start).

Safety – For our safety, sensors are fitted to the seat, blade engages lever or button, transmission selector, brake pedal, and on some models, the hood. Any of these sensors will prevent your mower from starting.

On older manual transmission mowers, the gear selector wears, and although the selector points to the Neutral position, it’s often still in gear – confirm it’s in Neutral by pushing it forward or back; it should be easy to push.

Sensors – This older style Craftsman / Jonsered / Husqvarna blade lever causes lots of no-start problems.

The lever spring gets weak and leaves the sensor in the open position which prevents starting.

Sensors – The quick fix, hold down the lever to start the mower. The complete assembly is available and not too difficult to fit. Check that all sensors are working, and look to see if the striker plates are closing the sensors fully.

Check wiring to sensors for chafing and that the connectors are secure and corrosion-free.

Check Control Module

Most modern mowers will have a Control module; they are a printed circuit with relays and resistors – they do give trouble. Because the specs vary, I can’t be more detailed.

The function of the control module is to receive a start/stop command from the ignition switch and only output a start command to the starter (via the solenoid) if all the correct sensors have been engaged.

Replacement modules can be on the spendy side, so it may be time to access your old mower; if she needs a ton of love in the blades bearing and belts department, it may be time to look at a new set of wheels.

Module – Wires come loose, have a helper attempt to start the engine while you wiggle the wiring connectors.

Check also for damage, water, or scorch marks on the panel itself.

Check Ignition Switch

Ignition switches are an important part of the ignition system; bad connections here can cause lots of problems. Ignition switches – send commands to the control module if fitted.

If your mower doesn’t have a control module, then the safety sensors are wired inline to the ignition switch – meaning any sensor that is in the open position will leave the ignition switch with an open circuit (No start). These systems are basic and tend to be the most reliable.

Common Problems

Issues with ignition switches: loose wiring at the switch; corroded terminals; broken terminals; spinning ignition switches.

Wiring specs for ignition systems vary, so I can’t be more detailed. Check the ignition wiring for damage, corrosion, or loose wires. Have a helper sit on the mower and attempt a start while you wiggle the ignition wires and connectors.

• Check ignition inputs – ground and 12-volt supply.
• Check ignition outputs – 12v to the starter solenoid (or to the control module, if fitted) when the ignition is in the start position.

Switch – Spinning ignition switches cause damage to the wiring and pins.

Corrosion is another common failure. This usually causes unreliable starting and shutdowns.

Wiggle – Try wiggling the wires at the back of the ignition switch while attempting to start the engine; you may need a helper. Often wires simply come loose but do check them for corrosion.

My Greenworks Mower Won’t Start – Causes And Solutions

After a cold winter, spring comes to bring your lawn to life. Your lawn is starting to revive and needs to be neatly trimmed. However, you suddenly discover that “My Greenworks mower won’t start”.

You begin to ask questions related to the Greenworks lawn mower problem after a period of not being used. Does it run out of power or is it due to the neck of the plugs and switches?

To answer this question, let’s learn about the causes of Greenworks lawnmowers not working and how to fix these situations in the article below.

My Greenworks Mower Won’t Start – How To Fix It?

There are many causes of Greenworks lawn mowers not starting such as a dead battery, low battery, problem with power switch or wiring and socket problem. To fix this situation, you need to identify some of the common causes below.

The Battery Is Dead

The first cause that you can think of when the Greenworks lawn mower won’t start is a dead battery. Usually, the grass will hibernate in the winter and remain dormant. Therefore, very few people mow the lawn in the winter, especially since this affects the revitalization of the lawn in the spring.

It is for this reason that lawn mowers in general and Greenworks lawn mowers, in particular, will not be used during the winter months. As a result, the battery may wear out and run out of power during this time.

The Greenworks lawn mower Lithium-Ion battery can maintain most of the power in the machine for long periods of storage. However, if you store your Greenworks lawn mower when it’s running low on battery, it won’t be able to sustain power for the winter months and start-up when you flip the switch.

Greenworks lawn mower batteries have a lifespan of up to 2000 charges and a 2-year warranty. If your lawn mower operates for three years or more, the battery may be low. Therefore, it may not be able to conserve energy even when fully charged during winter.

One reason why Greenworks lawn mower batteries are severely affected is excessive heat. Excessive heat kills the battery and can cause the battery to leak energy or explode.

If you find the Greenworks lawn mower is not working, you can try to put the battery in the charger to see if the light is green or not. Besides, you should charge about 50% of the battery before storing it over the winter to prolong its life.

You should not let the battery drain and store it for a long time. Because it will cause the battery to wear out quickly and not have good storage capacity. If the battery drains quickly and often cannot start the lawn mower, you should replace the battery with a new one to limit this inconvenience.

Power And Power Cord Problem

One of the other top common causes is problem sockets and wires. If your lawn mower uses a cord that plugs into the mains, be sure to check it for power.

After you have tested the battery and know that it still has power. Sometimes, the problem is very simple the power is off, so the lawn mower cannot start. You need to test the outlet with another electrical device to see if it works.

Next, if the power supply does not have any problems, you need to check the wiring. The cord of the lawn mower can be damaged by insect damage or worn during use, resulting in inactivity.

Make sure the conductors have no gaps, the connections are not broken, and are in good working order. You can use a power source with another device to find out the exact cause.

To limit the situation of wires being worn or damaged by insects for many months, you should wrap the wires carefully with specialized bags and avoid areas with rodents such as mice, cockroaches, termites …

Start Switch Broken Or Faulty

Some technical errors can often occur in the switch of the lawn mower. If you use the lawn mower regularly, pressing the switch button will happen continuously. In particular, during mowing, you also need to turn this switch on and off to clear the grass deck. Because it can’t hold too much grass and debris.

If you’ve checked the top causes like the battery, power supply, and wiring are working fine, the big reason is the switch. With this situation, you need to contact the repair center of Greenworks lawn mower for inspection and advice.

The Last Word

A Greenworks lawn mower that won’t start can be related to some fundamental issues such as a dead battery, damaged power supply, wiring, or control switch.

Greenworks lawn mower batteries can become depleted after months of inactivity. Especially, for batteries with a lifespan of more than 3 years and operating at high capacity, wear and tear are inevitable.

In addition, you should also check the power supply and wires with another electronic device to make sure there is power and that the wires are not having wear or tear problems.

Finally, the problem may lie in the toggle switch due to frequency of use or technical failure. Therefore, you need to contact the repair center for advice and a warranty.

Problems With Electric Start Lawn Mowers

Electric starting mechanisms eliminate the need to pull tirelessly on a rip cord in order to get your lawn mower running. Instead, when using an electric start mower, you simply need to flick a switch or turn a key, just like with an automobile’s ignition. Despite the several advantages of electric starting mechanisms, the mowers that utilize them can still have several problems.

Power Cord Chaos

Most electric start mowers on the market are entirely electric, using electricity to power cutting bladesand front or back wheels with self-propelled modelsin addition to powering starting mechanisms. Obtaining the electricity for an electric mower typically requires running a power cord across your lawn to an indoor or outdoor power outlet. In most instances, manufacturers do not include long cords with the mowers, which means you have to spend additional funds on an extension cord before you can cover any real distance, according to the lawn mower resource, Lawn Mower 411.

However, there are limits when it comes to using extension cords with electric mowers, which means the mowers are not well-suited for covering large areas. You should never use more than 230 feet of cord, according to the lawn mower resource Lawn and Mower, otherwise your mower may not run properly. In addition, towing around a power cord while you mow can be a hassle, and running over it is an electrocution risk.

Lack of Power and Durability

An alternative to the corded, all-electric start mower is the cordless battery-powered all-electric start mower. While this type of mower eliminates the hassles of a traditional pull-start mower without reverting to the use of chaotic power cords, the mowerlike all electric mowersstill has several problems. The cordless mowers are often not sturdy enough for heavy-duty landscaping and professional lawncare work and are much less powerful than gas-powered mowers, the lawn mower resource, Electric Lawn Mowers, reports.

Battery Drawbacks

There are some mower models, such as the Honda HRX217K2HMA, which utilize standard, cord-free, gasoline-powered engines in combination with electric start mechanisms. Instead of receiving electricity from power outlets, these starting mechanisms run on battery-power; eliminating the distance-restrictions, hassles and risks associated with using corded electric start mowers. Using such a mower also eliminates the power and durability problems associated with electric mowers in general.

The downside, however, is when the battery powering the starting mechanism of a gas-powered mower dies, you cannot start the mowerunless, of course, the mower has a back-up, pull-start mechanism. So even though you may be able to take an electric start, gas-powered mower further than an all-electric model, if it breaks down, you will have to push it all the way back to charge or replace the battery.
