Reason 1: No Flow of Sparks

No flow of sparks becomes a common matter after using the same spark plug for a certain time.

Because it becomes very dirty and sometimes, the connection gets loosened. As a result, the engine gets no flow of sparks and thus the mower stops.

Solution: Clean the Spark Plug and Reconnect It

At this point, you can try by cleaning the spark plug very carefully. After that, go through its connection and the best way is reconnecting it.

Reason 2: Battery Draining Power

The battery on a Dewalt lawn mower is responsible for providing it the required power to run.

But, if dirt has badly attacked the battery and its compartment, the power flow can get interrupted. In some cases, a completely defective battery is the culprit.

Solution: Clean the Battery or Replace It

To get the power flow from the battery, wipe it and its compartment thoroughly with a dry cloth. If you catch the battery is defective, replace it without a second thought.

Reason 3: Less Air Than Needed

To run the lawn mower, just as fuel, air is also needed.

But, if the air filter is blocking air with its clogged state, the mower will fill the lack of air. And, due to it, the fuel mixture in air will be wrong and the engine may not run with it.

Solution: Inspect the Air Filter and Purify It

To free the air flow to the mower, inspect the air filter. Purify it considering the material it is made of. Otherwise, you may damage it while cleaning.

Reason 4: Old Fuel in Use

Old fuel in use is a common reason that helps the Dewalt lawn mower to stop running repeatedly.

It is because the efficiency in old fuel is low. And, it is not enough to guide the engine to run continuously.

Solution: Drain the Fuel and Fill the Tank with New Fuel

To get rid of old fuel, drain the fuel from the tank. And, be cautious to clean the tank to erase the residue created by the old fuel. Then, fill the tank with fresh and new fuel.

Reason 5: Ignition Coil Not Working

An ignition coil is undoubtedly an important component of the Dewalt lawn mower.

But, as soon as it stops working, the process of igniting the sparks also stops. In other words, the engine doesn’t get the assistance from the ignition coil to function.

Solution: Check the Coil Connection

Many things can happen to the ignition coil and therefore, a better option is checking it evenly. In case there are any loose wires or connections, fix that without delay.

Why Does My Dewalt Lawn Mower Run for a Few Seconds then Die?

Answer: A dirty carburetor is probably the most effective reason as it won’t flow fuel when it gets dirtier and finally, clogged. Another one is the lack of sparks from the spark plug. Even the clogged air filter or the fuel filter can cause it, too.

Why Does My Dewalt Electric Lawn Mower Keep Shutting off?

Answer: In case your Dewalt electric lawn mower keeps shutting off, the cable connection can have defects. For example, a loose connection is undoubtedly a barrier in flowing electric power. Thus, the electric mower can not run uninterruptedly.
