Reasons behind john Deere won’t move forward or reverse

If your John Deere won’t move forward or reverse, it can be a big problem if you’re using it to do your chores. There are plenty of reasons why your John Deere won’t move. Here are some of the most common reasons:

Clogged fuel or air filters. The first thing you should check is to see if your John Deere has clogged fuel or air filters that could be causing the problem. Issues in the battery or carburetor. There could be an issue in the battery or carburetor that is preventing it from moving properly. Transmission failure. If none of those things help, then there might be an issue with the transmission that is preventing it from moving forward or backward. There could also be a larger issue with the motor itself that is causing this problem. 

Clogged fuel or air filters

Clogged air filters can cause a lawn mower to run hot and burn out the engine. Replace filters after a few months of usage and clean them regularly before each use.

A clogged air filter restricts airflow, causing the engine to overheat. The same is true of a clogged fuel filter. Both damage the engine and can void your warranty. The only way to fix an overheated engine is to replace it.

Fuel filters prevent gasoline from reaching the carburetor, which means the mower won’t start. The fuel filter is on top of the gas tank, either inside or underneath a metal cover. 

To check or replace a fuel filter, remove the cover and press down on the center of the filter with your thumb. If it resists pressure, get a new one; if it feels soft and spongy, you have time to clean it before installing a new one.

Faulty battery or carburetor

So you’re mowing your lawn and the john Deere mower suddenly stops moving forward or backward. The engine may be running, but you can’t get it to move. What’s wrong, and how do you fix it?

There may be a number of problems that can cause this. Most of them are pretty easy to diagnose and fix, but if you don’t know what the problem is, it can be difficult to figure out how to repair it.

The most common causes for a john Deere mower to stop moving are:

Faulty battery: If your battery is weak or dead, it won’t have enough power to push the mower around. Sometimes a bad connection between the battery and the mower will keep it from working.

Faulty carburetor: A carburetor mixes gasoline and air to provide an appropriate ratio of fuel for combustion. It also controls engine speed depending on its position. If the throttle cable gets stuck or disconnected, the carburetor won’t have any effect on engine speed or operation.

Trouble with spark plug wires. If the spark plug wires aren’t connected properly, they may not connect with the spark plugs when they need to fire, making it impossible for them to send electrical

Faulty Transmission

John Deere mower transmission is a complex mechanism that allows the operator to move the machine forward and backward with ease. The transmission has several components which can fail due to wear and tear, or damage. 

Transmission failure can result in an inability to shift gears. It may also prevent the mower from moving forward or reverse. These issues can be caused by problems with the transmission itself, or with the shifting mechanism located behind the engine.

When one of these components fails due to normal wear and tear, it will not pose a major problem for the operator. If you have been using your John Deere mower for a long time and have never had your transmission serviced, it is probably time to do so. 

Transmission failure on a John Deere mower may leave you stranded in the middle of your yard or garden without any way of moving your mower. The transmission failure may cause you to be stuck in one gear only. 

It can cause you to not move at all and damage may also prevent you from moving. In some instances, you may face other John Deere mower problems in the future if you do not get your transmission serviced on time.

How do you fix problems on your John Deere Riding Mower

When your John Deere riding mower isn’t starting or is difficult to start, the problem could be with the drive belt, carburetor assembly, engine carburetor, engine tune-up or dead battery. 

Check the drive belt first. It’s easy to check if it is damaged and replace it if necessary. A drive belt connects the engine to the transmission, which turns the wheels and propels the mower forward. 

The belt must be in good condition for the mower to work properly. If you are unsure about what kind of belt your John Deere riding mower has, consult your owner’s manual for identification.

If the belt is intact, check the carburetor assembly next. Disconnect the fuel line and spark plug wire from the engine to do this. 

Pull out the air filter and check that it is clean and clear of debris. Check that the fuel lines are not clogged or leaking. Remove any debris from the carburetor and replace any worn gaskets or seals.

If you have access to a spray starter fluid, squirt some into the carburetor with a long-reach small hand nozzle to clean it and try to start the engine. If this works for a few seconds before dying again, then there is a problem with the carburetor that needs repair or replacement. 

Clean the carburetor first. If replacing the carburetor doesn’t solve your problem, check that all gas lines are free of leaks and that there’s no debris in them. Then look for any loose connections between spark plugs wiring harnesses and other electrical components that may be causing a short circuit.


In the end, it’s all about working to help keep your John Deere riding mower in top operating condition. By doing this, you’ll get maximum use from your riding mower, which means that you’ll be able to spend more time on the things that matter to you.
