Solutions Discussion: John Deere Lawn Mower Keeps Shutting Off?

Without catching the reasons, do not assume anything regarding a John Deere lawn mower keeps shutting off. Because a tiny oversight of the user can cause it easily.

To help you with the issue, a complete guidance is discussed with each trifle.

So, why don’t you take a glance at the guidelines?

Reason 1: No Fuel Pumping

No fuel pumping indicates the fuel pump is malfunctioning or not working.

It can get weakened or inefficient or completely bad. When no fuel pumping happens, both the carburetor and the engine face the need of fuel. As no fuel goes there, the mower won’t run.

Solution: Check the Fuel Pump and Replace It

Before you get another one, check the fuel pump evenly to see if any repair can help. If it is not working, install a new fuel pump that will pump fuel and let them go.

Reason 2: Obsessive Current Flow

Excessive amount of current flowing through the electric terminals can stop the mower suddenly.

Because when the battery works with loose connections, obsessive current flow hits the mower. It also results in making the fuse blown.

Solution: Change the Fuse or Secure Battery Connection

To uproot the problem, secure the connections of the battery by readjusting the wires. Then, check for blown signs in the fuse and replace it if you find it bad.

Reason 3: Using Bad Fuel

Continuously using that old fuel in your John Deere lawn mower barriers the engine from running.

Because the older it gets, the worse it becomes. No efficiency is left with it and the engine faces troubles in working with it.

Solution: Drain the Fuel and Get New Fuel

In case the fuel is in the tank more than 30 days, drain it immediately. Clean both the tank and the carburetor and fill new fuel.

Reason 4: Excessive Dirt in Mower Deck

The John Deere lawn mower deck getting full of grass, dirt and debris is a common scene. But, when you do not clean it regularly, the deck gets fraught with excessive grass and debris.

Consequently, the deck faces issues in operating and feels a heavy load. Thus, the overheating motor appears and the mower stops.

Solution: Remove Dirt and Grass from the Mower Deck

Reach the mower deck and remove the dirt, grass, debris and soil from it. Then, wipe it to avoid rust from starting to live. It would be better if you sharpen the mower blades along with it.

Reason 5: Clogged Fuel Filter

A clogged fuel filter won’t purify the fuel anymore, rather it will hinder it from flowing.

Because when it is left uncleaned, it gets clogged over time. As a result, the road becomes blocked and fuel fails to go. And, the engine stops due to less fuel.

Solution: Purify the Fuel Filter or Install a New One

In this respect, you have to purify the fuel filter and observe if fuel is going through it after cleaning. If you notice it has become bad, install a new fuel filter.

Why Does My John Deere Lawn Mower Randomly Stop?

Answer: A John Deere lawn mower stopping randomly is a sign of faults in the spark plug and the carburetor. A few more causes are the air filter clogging and the engine getting zero fuel and the carburetor has defects.

Why Does My John Deere Lawn Mower Keep Stalling?

Answer: The stalling problem in a John Deere lawn mower is invited by the inaccurate fuel delivery. When the fuel flow is less than recommended amount, the fuel pump or engine or the carburetor fails to work and stalling appears.

End Words

A John Deere lawn mower tends to come up with various issues but this one is indeed tiring. When a John Deere lawn mower keeps shutting off, no job of the lawn can be completed.
