Deere lawn mower may not start because of an issue in the fuel system, a clogged air filter, a dirty carburetor, a bad battery, a safety switch, bad spark plugs or a faulty ignition switch. A stalling engine can be caused by a charging system or ignition coil problem. If you suspect a problem with your lawnmower, contact your local dealer for assistance.

When I turn the key on my lawn mower and nothing happens?
It could be a variety of things, if your riding lawn mower doesn’t start when you turn the key. The video shows you how to determine the cause by checking the riding mower’s battery, solenoid posts and coil, fuse, ignition switch, brake and clutch. If you’re not sure what’s wrong, you can contact your local dealer.
Why is my lawn mower cranking but not starting?
An air filter that’s not letting enough air into the motor can inhibit combustion. The plastic cover on your mower needs to be removed. The reason for your lawn mower turning into a fire hazard is if the filter is covered in dirt or grass.
Does John Deere have an electric zero turn mower?
Making the most of your mow starts with a heavy duty engine that can do almost anything. You’ll find that a John Deere Zero-Turn mower can save you a lot of time and money.
What is the choke symbol on a lawn mower?
The choke symbol is in the on position restricting air into the engine when the lever points to an angled or horizontal line. ‘Start’ can also be used to designate this. The lever points to a vertical line or the center of the throttle body when the choke is off.
When the clutch pedal is depressed, air is forced from the intake manifold to the cylinder head. The intake valve is closed and the exhaust valve opens to allow air to enter the cylinders. When air enters the combustion chamber, it pushes the piston forward and compresses the fuel/air mixture.
As the pistons move forward, they compress the air/fuel mixture until it reaches a certain pressure. At this point, the spark plug ignites, igniting the mixture of fuel and air. If the ignition timing is not set correctly, a spark will not occur and a fire may occur. In either case, an engine fire can result.
Where is the choke on my lawn mower?
The choke valve is located on the body of the engine or a lever on the handle of a lawn mower. The butterfly valves in the choke valves are mounted up from the crankshaft. Choke valves have two main functions. First, they control the flow of air through the combustion chamber to the cylinder head.
The second function is to regulate the amount of fuel that is injected into the cylinders. In the case of a carburetor, these two functions are combined into a single valve, which is known as a “throttle valve.” The throttle valve controls how much fuel is allowed to flow into each cylinder.
As a result, more fuel must be injected to achieve the same level of combustion. This is called “overboost” and is a common cause of engine failure. Overboost can be caused by a number of factors, such as poor fuel economy, poor throttle response, or an engine that has been running for a long period of time without any maintenance.
