What You'll Learn
Ensure the mower is correctly set up
To ensure your Kobalt 24V electric mower is correctly set up, you should first check that the mower blade is secure and has not come loose. You can do this by checking if the blade turns freely or with resistance. If the blade turns freely with no resistance, it may have become disconnected from the motor.
Next, make sure the upper handlebar is fully pulled out and the latches are fully closed. There are switches inside the latches that need to be closed for the mower to operate. If the mower still won't run, there could be a problem with the switches not closing, or there may be another wiring problem.
If your mower is new and you are setting it up for the first time, make sure you are starting it correctly. Hold the start button, then pull back the bail bar.
If your mower is a newer model, there may not be a yellow key by the battery. Instead, look for a small bin with a black button by the battery compartment.
If your mower is not starting, check that the battery has enough power. If the battery is fully charged but the mower is still not starting, there may be a problem with the switches or wiring, as mentioned above.

Check the battery
To check the battery of your Kobalt 24v electric mower, first locate the battery compartment. The battery is typically placed underneath the mower. Once you have located the battery, check its charge level. This can be done by examining the power lights on the battery or by using a voltage meter. If the battery is not fully charged, connect the battery to the charger and allow it to charge fully before attempting to start the mower again.
If the battery is fully charged and still does not work, there may be a problem with the battery itself or the connection between the battery and the mower. In this case, try removing the battery from the mower and then reinserting it, ensuring that it is properly connected and secured in place. Check for any signs of damage or corrosion on the battery terminals and clean the terminals if necessary.
If your mower starts but dies after a few seconds, this could be due to low voltage or a safety issue. The Kobalt mower typically emits beeps to indicate low voltage or safety concerns. If you hear these beeps, inspect the wiring and connections for any damage or loose connections. Ensure that all switches are closed and functioning properly, as a faulty switch can also cause the mower to shut off prematurely.
If you are still experiencing issues with your Kobalt 24v electric mower after performing these checks and troubleshooting steps, it is recommended to consult a Kobalt Small Engine Technician or a qualified repair specialist for further assistance. They can help diagnose and resolve any remaining issues with your mower's battery or other components.

Check for unusual noises or vibrations
If you experience any unusual noises or vibrations when trying to start your Kobalt 24v electric mower, it could be due to several reasons. Firstly, check if the mower blade is damaged or out of balance. A damaged blade or one that has been sharpened incorrectly can cause uneven weight distribution while it spins, resulting in increased noise and vibration. Inspect the blade for any damage and test its balance by hanging it on a nail driven into a wall through the centre hole. If the blade is damaged, replace it, and if it is unbalanced, sharpen or replace it.
Another potential cause of unusual vibrations is a bent crankshaft. This can occur when the mower strikes a solid object like a rock or tree stump, causing a sudden stop. Even a slight bend in the crankshaft can lead to excessive vibration due to the unbalanced spinning blade. If you suspect a damaged crankshaft, discontinue use immediately and seek professional repair services.
Additionally, pay attention to any beeping sounds. Beeping noises in Kobalt electric mowers often indicate that the tool is not safe to operate due to safety switch issues or low voltage to the control board. Ensure that you follow the correct starting procedure, as accidentally pulling back the bar and then hitting start can sometimes prevent the mower from starting.
If your mower is new and the blade motor will not engage, it could be due to a lack of information and parts availability. In such cases, you may need to modify replacement parts to get the mower working.

Check the blade is connected to the motor
To check if the blade is connected to the motor of your Kobalt 24v electric mower, you must first inspect the nut that holds the mower blade in place. This nut is located in the centre of the blade. If it is loose, the blade may not turn. Therefore, it is important to ensure that the nut is tight.
Next, check to see if the blade turns freely or with resistance. To do this, try turning the blade with your hand. If the blade turns freely with no resistance, it may be disconnected from the motor.
If you suspect that the blade is disconnected from the motor, there may be a problem with the start sequence. The correct start sequence for the Kobalt 24v electric mower is to push and hold the start button, and then pull down the top handle to start the blade. Ensure that you are following this sequence correctly.
If the blade still does not turn and you suspect a disconnection, further troubleshooting may be required. You may need to consult a professional or seek advice from a community forum to resolve the issue.

Try troubleshooting
If your Kobalt 24v electric mower won't start, there are several troubleshooting steps you can take to try and resolve the issue.
Firstly, check that you are starting the mower correctly. Ensure that you are holding the start button and then pulling the bar back.
Next, check the battery. Make sure that the battery is fully charged and that there are no issues with the charging unit or power source. If the battery is beeping, this could indicate low voltage to the control board or that the tool is not safe to run. If the battery won't charge, you may need to seek professional help.
Inspect the start button for any visible damage and check that it is not stuck. Use a multimeter to test for electrical continuity, and replace the button if any issues are found.
The safety key is another crucial component. Ensure that it is inserted properly and check for any dirt or debris around the key slot. Inspect the key itself for any cracks or damage, and then test it by inserting it and attempting to start the mower.
If your mower has a self-propelled feature, check that the blade turns with resistance. If it turns freely with no resistance, it may be disconnected from the motor.
If basic troubleshooting does not resolve the issue, you may need to seek assistance from a Kobalt Small Engine Technician or another authorised service centre.
