9 Reasons Greenworks Lawn Mower Won’t Start (Troubleshooting)

Greenworks lawn mower won't start

1. Mower starts then stops

If you are experiencing problems with your Greenworks Lawn Mower starting and then stopping, there are several things you can do to try and fix the problem. You should check if the cord is damaged or frayed. Make sure that the spark plug is clean and well-lubricated. If the grass catcher is blocking access to the spark plug, remove it so that you can get at it more easily.

Once you’ve done these simple checks, try starting your Greenworks Lawn Mower again and see if it starts and runs properly this time around.

The issue with a start and then stop in Greenworks Lawnmower is usually caused by worn-out parts. When these parts wear out they can no longer hold the motor in place and allow it to vibrate freely. 

This can cause issues with the blades, clutch, and motor itself. Another solution is to take a close look at your lawn mower. Check to see if any parts are loose or damaged.

A loose part may be causing vibrations that are making it difficult for your grass to cut properly. Broken or damaged parts also need to be fixed before you can get rid of a start then stop in Greenworks lawn mower.

2. Battery says fully charged but not working

There are many reasons why your GreenWorks lawn mower battery may not be working. You need to understand the different issues that cause a low battery, including:

  • Reduced charge capacity due to poor connections or damaged cables. 
  • Low-quality battery that is not properly maintained, or has been replaced with a substandard model.
  • Use of an incorrect charger, especially one with a slow charging rate, which prevents the battery from fully recharging. 

Routinely overload the battery by constantly using the equipment for longer than recommended. Elevated temperatures in the area where you use your GreenWorks lawn mower. When your GreenWorks lawn mower says that it is fully charged but the engine is not turning over, there are a few things that you can do. Please double-check the plug that connects the charger to the wall. 

Any regular 120V power outlet will do. The outlet design should match the plug design. You shouldn’t try to fix the plug yourself. Make sure the battery’s contacts are properly mated with the charger before plugging it in. There should be LEDs on the battery that tell you how much charging you have left.

 If they are, then try to reset the battery’s settings by removing the key from the ignition and waiting 30 seconds before re-inserting the key.

This will reset the battery and ensure that it is ready for use. If this doesn’t work, then you may need a new battery or charger. If this is the case, then you should contact a reputable local hardware store to help you with either of these options. 

3. Lawn mower blade not spinning

When you’re mowing your lawn, sometimes you may notice that the blades aren’t spinning. If the blades aren’t spinning, there could be a couple of reasons. There are a few things that could be causing this issue, like a clogged blade or an issue with the belt or drive pulley.

You can try unclogging the blade by removing the grass and debris and then cleaning out any debris that may be blocking the way. 

You can also check to make sure the belt or pulley is tight enough. You also have to make sure that your mower is running correctly. If you’re still having issues, you can try adjusting the height of your mower to see if that fixes it. If the blade isn’t turning at all, make sure it’s turned on. 

It may be loose or have fallen out of place. Sometimes this can be fixed by tightening the screw that holds it in place. Make sure to tighten it only until it’s snug but not so much that you damage the threads of the screw head. You may also need to replace broken or worn blades.

4. Corded lawn mower won’t start

There are many reasons why a corded lawn mower will not start. Some of the more common reasons include a discharged battery, defective cord, or plugged starter. Before starting to repair a lawn mower, it is important to determine the exact cause of the problem.

This will help ensure that the right repairs are made and also prevent additional problems from occurring. The first step in any repair process is to check for obvious signs that can help identify where the problem is located.

These signs include broken or frayed wires, melted insulation, and loose connections. If these signs are present, the problem is likely located in the electrical system. If this is the case, several things can be done to correct the issue.

First, check for loose connections by moving metal parts such as screws and nuts around with your hands until you feel a connection loosen up. 

Once you have identified the location of the problem, it is time to fix it. This can be done by tightening loose connections or replacing broken parts. Make sure to refer to your mower’s owner’s manual for specific instructions on how to complete each step of the repair process.

5. Lawn mower not collecting grass

If your lawn mower is not catching the grass, it could be several things. Here are some of the most common causes like a clogged or restricted grass collector. This could be a blockage in your mulching blade, a damaged rope or hose, etc.

If this is the case, you need to clear out the blockage and re-adjust the mower’s settings to ensure that it can collect more grass. The grass catcher doesn’t have enough area to collect all the grass. 

For example, if the area where it should be collecting the grass is narrow and it’s in a tight space between two hedges, then it can’t get all of the grass under control. The height at which you cut your lawn may not be right for your mower. For example, if you need to cut at a height of 1 ½ inch and you only have a 2-inch mower, then you won’t be able to cut at that height.

6. Mower keeps shutting off

When a mower shuts off unexpectedly, it can be frustrating. However, you can usually fix the problem yourself. It can be due to a clogged air filter. Clean the air filter to remove debris so the blades can properly spin. The trouble with the throttle lever. Make sure the lever is not stuck or damaged. Blocked airflow ports on the head or body of the mower.

Clear them by removing debris or replacing a flat piece of rubber on the deck. Loose connections in wires and cables. Check for any loose connections and tighten them as needed. Lubrication issues between moving parts. Lubricate all moving components as needed to help prevent jamming or seizing up.

7. Lawnmowers auto throttling

There are many reasons why your lawn mower may be auto-throttling. It could be:

  • A blade that is dull or sticking
  • Clogged air filter
  • A worn-out throttle cable
  • Dirty carburetor

If you notice any of these issues, take a minute to inspect your mower. Cleaning it out and replacing any worn parts will help keep it running smoothly. One of the easiest ways to tell if your lawn mower is working correctly is to check its fuel gauge. 

8. Lawn mower vibrates and makes weird noises

Sometimes your Greenworks mower starts to vibrate and make weird noises. There are a few things you can do if your mower is vibrating and making strange sounds. In this case, you should inspect the blades. If they are not properly adjusted, moving them back in place will help reduce the vibrations.

You should check the handlebars. If they are loose, tighten them to reduce the vibrations. Check the deck for any debris that may be blocking it. Clean it off so your mower runs smoothly.

9. The mower is not cutting or mulching well

There are a few reasons why your mower may not be cutting or mulching well. It could be that the mower blades are dull or not sharp, it could be that the grass is too long and overgrown, it could be that the grass is too wet, or it could need a tune-up. Each of these things can cause your mower to have trouble cutting or mulching. 

So, what should you do if you find yourself with a poorly mowing machine?  Check the blades to make sure they are clean and sharp. If they are not, get them sharpened right away. Check the grass to make sure that it is short enough for your mower to work properly. If it is too long, ask your lawn service company to come out and mow it for you. 

Take your mower in for a tune-up every once in a while. By doing this, you will be able to get rid of any problems with your machine and keep it running like new.


Your home lawnmower is an important tool. Modern lawnmowers allow you to control how much effort it takes to cut the grass and when you need to add more gas or oil. It can also make lawn mowing a little easier on the knees. However, sometimes the machine just doesn’t want to start.

If you’re experiencing an issue with your GreenWorks lawnmower, take a moment to look through these troubleshooting tips to see if they might help you get the machine back in working order.
