If you own a Kobalt 80v mower, you may eventually encounter some common problems.

Have you ever gone to mow your lawn only to find that your mower won’t start? Or, maybe you’ve been mowing for a while when suddenly the blades stop spinning. While these problems can be frustrating, they’re quite common.

We will go over some of the most with the Kobalt 80v mower in this blog post, along with fixes.

By the end of this post, you will better understand how to troubleshoot and fix these issues should you encounter them.

The Most Common Problems with Kobalt 80v mower

If you are the owner of a Kobalt 80V mower, you might have encountered one or more of the issues listed below.

Look at the most typical Kobalt 80V lawn mower issues and their fixes. Learn more by reading on!

1. The mower won’t start. 

If your mower won’t start, the first thing you should check is the battery. To ensure that your installation is complete and secure, double-check the terminals.

The spark plug should be checked following a successful battery test. The spark plug might need to be replaced if it’s dusty or damaged.

If the battery looks fine, the blade switch is the next thing to check. The mower will not start unless the blade switch is in the “on” position. If it’s not, flip it to the “on” position and try starting the mower again

If neither of those fixes the issue, there might also be a problem with the fuel tank or line. Check the gas tank to make sure there’s enough gas in it.

If there’s no gas in the tank, add some and try starting the mower again. 

If neither of those solutions works, there might be an issue with the starter motor. To test this, disconnect the spark plug wire from the spark plug and then attempt to start the mower.

If it starts, you know the problem is with the spark plug or spark plug wire. If it still doesn’t start, there could be a problem with the flywheel key or the ignition coil.

Both components are inside the engine, so if you’re uncomfortable working on engines, we recommend taking your mower to a qualified repair person

2. Kobalt 80v Mower Is Leaving Stripes.

There are typically two root causes for this. The first thing to check is the blade height adjustment. If the blades are too low, they will scalpel the grass instead of cutting it evenly.

The next thing you should check is the wheel alignment. If the wheels are misaligned, the mower will pull in various directions and develop stripes.

3. The mower isn’t cutting evenly. 

If your mower isn’t cutting evenly, it could be because the blade is dull or damaged.

First, inspect the blade and, if necessary, sharpen it or replace it with a new one. It could also be because the wheels need to be inflated to the proper pressure. Keep your tires inflated adequately by regularly checking the pressure in all four of them.

Second, check the grass blade’s height and adjust it if necessary. Third, ensure that nothing is blocking the path of the grass blade, such as stones or sticks.

Next, check to see if the wheels are inflated properly. If they’re not, inflate them to the proper pressure and try cutting grass again.

Lastly, check to make sure that all four wheels are level with each other. If they’re not, adjust them so they are, and try cutting grass again. 

4. Kobalt 80v Battery Isn’t Holding a Charge.

There are a few things you can do to remedy the issue if you notice that your battery isn’t retaining a charge as well as it once did.

First, clean all terminals with a wire brush and ensure they’re free of corrosion.

Second, try charging the battery using a slow charger instead of a fast charger. And finally, if neither of those solutions works, you may need to replace your battery altogether. 

5. Kobalt 80v Mower Keeps Stalling.

This is usually caused by one of two things: something wrong with the carburetor or the fuel line/fuel filter/fuel tank.

First, try cleaning out the carburetor with a carburetor cleaner to troubleshoot this problem. If that doesn’t work, you’ll need to replace whatever part is damaged or clogged. 

Also, ensure that you’re using fresh gasoline—gasoline sitting in your garage for months can cause problems for small engines like those found on lawnmowers.

Lastly, check your air filter and make sure that it’s cleanThe engine can stall out due to a filthy air filter restricting airflow.

6. The mower isn’t self-propelling. 

If your mower isn’t self-propelling, the first thing to check is the drive belt. Make sure that it’s tight enough and intact.

If the drive belt looks fine, then the next thing to check is the transmission. You may need to add oil or adjust the transmission belt tension. 

7. The mower is vibrating excessively. 

Excessive vibration can be caused by several things, such as an unbalanced blade or loose bolts/screws/nuts.

First, check for loose hardware and tighten as necessary using a wrench or screwdriver (as appropriate).

Second, balance the blade according to the manufacturer’s instructions if necessary.

8. The wheels are slipping on wet grass. 

If your wheels are slipping on wet grass, there are a few things you can do to fix the problem.

First, make sure that you’re using tires that are designed for use on wet grass. Second, reduce tire pressure to increase traction. Third, adjust your speed and take turns slowly.

Fourth, avoid driving over puddles of water if possible. Finally, if none of these solutions work, contact customer service.

9. The mower cuts off after a few minutes of use. 

Dirty or clogged air filters can impede the efficiency of your HVAC system if it is, clean or replace it with a new one.

Next, check the spark plug to see if it’s dirty or damaged. Suppose it is, clean or replace it with a new one.

Finally, check the gas tank to ensure enough gas is in it. If there’s no gas in the tank, add some and try starting the mower again. 

10. The Blades Won’t Spin 

Before taking your Kobalt 80V mower in for repairs, if the blades won’t spin, you can check a few things on your own.

First, make sure that nothing is blocking the blades from spinning freely. Sometimes grass or debris can get caught between the blades, preventing them from turning correctly.

If nothing is blocking the blades, check to see if they’re installed correctly. The blades must be installed with the correct side facing up to work properly. 

If neither of those solutions works, there might be an issue with the mandrel assembly or deck belt.

The mandrel assembly is located under the deck and houses both spindles holding each blade.

The deck belt is above the mandrel assembly and goes around pulleys on both sides to simultaneously turn both spindles.

If either of these components is damaged or not installed correctly, it can cause your blades to stop spinning correctly.

Again, both components require some knowledge of engines to fix properly; we recommend taking your mower to a qualified repair person if you need help solving these solutions.
