Are Lawn Mower Solenoids Universal?

Like many people, you probably don’t know too much about solenoids. But if you own a lawn mower, you must remain conscious of the potential dangers. In this guide, we will discuss what solenoids are and whether or not they are universal. We will also offer some advice on how to replace them if necessary. Stay safe out there.

What Are Lawn Mower Solenoids?

A solenoid is a category of an electromagnet. The coil in the solenoid creates a magnetic field when an electric current flow through it. This magnetic field creates linear or rotary motion. 

A lawn mower solenoid is a small cylindrical coil located just behind the flywheel, the large wheel on the back of the engine. The primary purpose of the solenoid is to engage the starter motor when you turn the key to start the engine.

The electrical current flows through the solenoids when the engine is started, activating the blades. The blades rotate rapidly, cutting the grass. 

Are Lawn Mower Solenoids Universal?

The solenoid is an essential component of any lawn mower, and without it, the lawn mower would not be able to start. There are different solenoids to other lawn mowers, but they all oblige the same vital purpose.

To ensure that your lawn mower will start when you need it to, it is essential to purchase a solenoid compatible with your specific lawn mower model.

While some solenoids are universal and will work with any lawn mower, others are not and must be matched to the correct model to function correctly.

If you’re unsure which form of solenoid you prerequisite, it’s best to refer to a qualified technician. With the help of a professional, you can be sure to choose the correct solenoid for your lawn mower and get it up and running in no time.

Are Mower Solenoids Interchangeable?

The answer to this question is a bit complicated. While some solenoids are universal, others are not. However, some aftermarket solenoids work with multiple brands of lawn mowers. 

These solenoids are often slightly larger than standard solenoids. However, they can be a practical option if you need to replace your lawn mower solenoid and cannot find an exact match for your model.

Additionally, some solenoids may require additional adapters to work correctly. It is best to consult your owner’s manual or a qualified technician to determine which solenoid is suitable for your lawn mower.

How Do You Bypass A Lawn Mower Solenoid?

If your lawn mower won’t start, one possible reason is a faulty solenoid. The solenoid is an electrical component that helps start the engine by supplying power to the spark plug. 

If the solenoid is not working correctly, it can avert the engine from starting. Fortunately, you can bypass the solenoid to get your lawn mower running again. Here’s how to do it:

  1. Pinpoint the solenoid on your lawn mower. It is usually located near the battery.
  2. Take a wire and connect one end to the battery’s positive terminal.
  3. Connect the other end of the wire to the small end of the solenoid.
  4. Take another wire and connect one end to the battery’s negative terminal.
  5. Connect the other end of the wire to a metal part of the engine, such as a bolt or screw. It will complete the circuit and allow electricity to flow from the battery to the spark plug, bypassing the solenoid.
  6. Try starting your lawn mower. If it doesn’t start, check the connections and try again.

You can easily bypass a lawn mower solenoid and get your mower running again with a few simple tools.

How Do You Test A Solenoid on A Riding Lawn Mower?

There are a few ways to assess a solenoid to see if it is working appropriately. One way is to use a multimeter to test the continuousness of the solenoid. Another way is to use a 12-volt battery and jumper cables to bypass the solenoid and see if the engine will turn over.

Follow these steps to test it:

  • Park the riding lawn mower on a level surface and set the parking brake.
  • Disconnect the negative battery cable from the battery using a wrench.
  • Remove the seat from the riding lawn mower, if necessary.
  • Locate the solenoid mounted to the side of the engine block near the battery. The solenoid will have two thick wires connected to it and a thin wire.
  • Use a wrench to disconnect the ground wire from the solenoid terminal marked “GND” or “ground.” Set your multimeter to read ohms, and touch one lead to the terminal marked with an “L” for low voltage and the other lead to the “S” terminal for high voltage. If the solenoid is working correctly, the multimeter should read continuity.
  • Reconnect the ground wire to the solenoid and reattach the seat and battery cable. Start the engine and test the riding lawn mower’s operation.

With a little bit of care and maintenance, your lawn mower should be up and running.

Is Starter Solenoid Universal?

A starter solenoid is a device that helps to start an engine by providing electrical current to the starter motor. They are often used in concurrence with a starter relay. While starter solenoids are not universal, they are often used as a Universal part. 

You can use it in various vehicles, including cars, trucks, bikes, and lawn mowers. Using a starter solenoid as a Universal part saves time and money when repairing or replacing a starter motor. 

However, it is worth keeping in mind that not all starter solenoids are created equal. Some are designed for specific vehicles, so it is crucial to check similarities before purchasing. It is easy to find the right starter solenoid for your needs with a bit of research.


In conclusion, lawn mower solenoids are not universal and must be matched to the correct model to function correctly. If you’re unsure which sort of solenoid you need, it’s helpful to access a qualified technician. With the help of a specialist, you should rest assured to pick the right fragment for your machine.
