How does a lawn mower hour meter work

A lawn mower hour meter is a device that is used to track the number of hours that a lawn mower has been used. This information is important for a number of reasons, including tracking maintenance schedules, determining when the lawn mower is due for a tune-up, and helping to ensure that the mower is running efficiently. In this blog post, we will take a closer look at how a lawn mower hour meter works and what you can do to keep your lawn mower running smoothly.

A lawn mower hour meter is typically attached to the engine of the mower and is powered by the mower’s battery. The meter works by keeping track of the number of hours that the engine has been running. This information is recorded and can be accessed at any time by the user. Some lawn mower hour meters are even equipped with a backlit display that makes it easy to read the information, even in low-light conditions.

The hour meter operates by using a small magnet that is attached to the flywheel of the mower’s engine. The magnet passes by a reed switch located inside the hour meter, which triggers the meter to record one hour of use. This process is repeated every time the engine is running, allowing the hour meter to keep an accurate record of the mower’s usage.

One of the main benefits of having a lawn mower hour meter is that it makes it easy to track when your mower is due for maintenance. By keeping track of the number of hours that the mower has been used, you can determine when it is time to change the oil, replace the spark plugs, or perform other routine maintenance tasks. This helps to ensure that your mower is running efficiently and that it will last for many years to come.

In addition to tracking maintenance schedules, a lawn mower hour meter can also be used to help diagnose issues with the mower. For example, if the hour meter suddenly starts recording fewer hours of use, this could indicate that there is a problem with the engine or the battery. By tracking this information, you can quickly identify the issue and get it fixed before it becomes a major problem.

how to reset hour meter on mower

The process for resetting an hour meter on a lawn mower can vary depending on the specific model, so it is best to consult the owner’s manual for your mower. However, here are some general steps that may apply to many models:

  2. Turn off the mower: Make sure the mower is turned off and the key is removed from the ignition.
  3. Access the hour meter: Some hour meters are protected by a small cover that needs to be removed to access the reset button. In other models, the reset button may be located on the back of the meter.
  4. Press the reset button: Once you have located the reset button, press and hold it for a few seconds until the display screen resets to zero.
  5. Reattach the cover: If you had to remove a cover to access the reset button, make sure to reattach it securely.

It is important to note that resetting the hour meter should only be done when necessary, such as when the mower is first purchased or when the battery is replaced. Keeping accurate records of the mower’s usage is important for tracking maintenance schedules and ensuring that the mower is running efficiently.
