A few crucial aspects of an hour meter for a lawnmower

● Why use a lawnmower hour meter

Hour meters are versatile and can attach to almost all lawnmower brands, including Ariens, Husqvarna, Honda, and Toro. If you would like to use one on your lawnmower, it is recommended that once you buy the lawnmower.

Consult the dealership and ask for an hour meter that is best compatible with the specific model you purchased. The small investment can have long-term benefits as the hour meter ensures timely maintenance, saving an individual from cumbersome damage and repair costs in the long run.

Types of Hour Meters

There are different types of hour meters in use. A one-hour meter records hours when the engine is running, while a second type records hours when the engine is idle. A third type of hour meter records hours when the engine is under load.

The term engine hours refers to the number of hours your engine has been running since it was new. Many machines idle and have a meter that tracks these engine hours. A distance meter would not track this idling time.

Understanding the Purpose of Hour Meters

The goal is to know when specific maintenance has to be performed that otherwise can easily be forgotten. Tracking the time you use a machine on paper is not as trivial as it seems and is often neglected. This is where an hour meter comes in handy.

It’s called an hour meter because it records the number of hours an engine has been running, similar to how a wristwatch records the number of hours in a day. An hour meter works by connecting to the engine’s ignition system and starts to run at the same time the engine does.

As someone who’s spent two decades in this field, I can tell you that the primary function of a lawnmower hour meter is to track the engine’s running time. It’s a simple yet crucial tool for scheduling regular maintenance and ensuring the longevity of your lawnmower.

This means it records the time the engine is on, whether used on a cut or just idling. This is why having an hour meter on your lawnmower is essential, as it helps you track when maintenance is required.

● Importance of hour meter for our lawnmower

The primary reason for using an hour meter is for maintenance. Suppose one relies on an engine’s actual running time to schedule maintenance for the prior service rather than depending on calendar dates or driven miles.

Using an hour meter helps you correlate more significantly to the equipment’s actual operating life, and there is way less guesswork involved.

– Service and maintenance in time:

In the case of a lawnmower, performing regular and scheduled service and maintenance is critical as it works in harsh situations when it comes to mowing your lawn. If poorly maintained, one can lose his hefty investment to buy a lawnmower.

Tracking running time to ensure that the oil, belt, filter, and spark plugs change and calibration checks are made is critical to keeping your lawnmower running.

Thus, one needs to monitor the running time judiciously and perform the service at regular intervals must be made for. A lawnmower and hour meter assist in this regard.

– If the warranty is on hours used:

Most of the lawnmower companies’ equipment types are warranted not by the days or years since the date of purchase but by the running hours. Thus, ensuring the equipment is under warranty depends on the time spent.

– Better resale value:

Certain lawnmowers are resale based on age, condition, and logged hours. Thus, an hour meter helps keep track of the logged hours on your lawnmower, which would further help in the machine’s resale.

Therefore, knowledge of accurate accounting of elapsed time can make a significant price difference when selling your lawnmower.

– Rent:

Lawnmowers could be rented as they are expensive tools. Other than that, lawnmowers are also rented for various projects and tasks regarding event management.

Thus, franchise operations that rent to professional crews could rent equipment at the hourly rate if an hour meter has been installed in your lawnmower. This could prove beneficial in monetary terms and helpful for maintenance. 

● Types of hour meters.

Hour meters have various types depending upon the power, display, shape, and data they carry.

– AC or DC powered:

They can be AC or DC-powered. A lawnmower that is supported electrically uses Direct current-powered meters according to its battery. Simultaneously, AC-powered hour meters and non-electrical versions of lawnmowers are preferred for riding.

– Mechanical or LCD:

They can have electromechanical or liquid crystal displays. Generally, lawnmowers use electromechanical hour meters to indicate running hours and tenth. These hour meters look like the car’s odometer and are vastly used for outdoor machines.

– Rectangular or round:

They can have rectangular or rounded shapes.

If you’re installing an hour meter on your lawnmower for the first time, I would advise following the manufacturer’s instructions closely. Ensure the meter is properly connected to the ignition system – a small step that can make a big difference in the long run.

– Hours or min:

Some hour meters can measure hours or one-tenth of an hour, while others could show a combination of data such as volt/hours.

● Factors when specifying an hour meter

Most hour meters are accurate and are pretty affordable. Depending on his preference, one could decide upon the design and the analog or digital display. Besides the styling, one should consider various other factors before installing the hour meter on his lawnmower.

– No Power:

In an electronic digital meter, a power outage could hamper an individual from doing readings, although the units will be recorded, and the total time elapsed will be saved.

At the same time, electromechanical hour meters are free from these constraints. Thus, one should prefer an electromechanical hour meter for his lawnmower.

– Ruggedness:

Regarding ruggedness, both the analog and digital hour meters are comparable in accuracy, power consumption, shocks, vibration, and temperature resistance. Both are also sealed and tamper-resistant.

– Panel profile:

Regarding the panel profiles, LCD meters have a shorter depth than analog ones. Due to their relatively more detailed profile, they can fit into skinnier panels. This helps in somewhat bigger machines such as airplanes, while in the case of a lawnmower, analog meters would work just fine.

– Noise:

Regarding noise and on/off cycles, analog ones are less silent than LCD hour meters. But this factor is not essential when considering a lawnmower. 

– Terminals:

Most AC meters have three styles of terminals. The spade terminal uses a fast-on attachment feature on an ¼ inch blade. The lead wire is held on the screw terminal with a screw. The wire lead termination style is simply a plain wire.

Over the years, I’ve encountered various issues with lawnmower hour meters, from inaccurate readings to complete failure. In most cases, these issues can be resolved by checking the wiring connections or replacing the hour meter.

– Accuracy:

Because electromechanical hour meters are designed and intended to track equipment’s total elapsed time, so they will be more accurate over extended periods.

Some use an instant start LCD meter if the application requires the hour meter to switch rapidly. An LCD meter also has the advantage of low depth, styling, and quiet operation. But the disadvantage is that it is only visible when the machine is on.

● The relation between miles and hours for an hour meter

The hour meters usually take readings in the form of hours or a tenth of an hour. The machine we are using is a lawnmower. Thus, we need to know how much distance or miles it has been used in addition to its operating time.

For this, it is necessary to realize the relationship between the miles and the hours. The distance will differ significantly between the type of lawnmower, the maximum speed, and the type of lawn. If the lawnmower has a distance meter, you can use that.

An alternative would be to use an exact GPS on your phone to track the distance, but this will probably not be as accurate as a distance meter. On most phones, the GPS is inaccurate and will fluctuate near buildings or under trees.  


This article briefly studied various aspects of an hour meter for a lawnmower. An hour meter allows lawnmower owners to improve their machines’ maintenance schedule.

One of the most significant benefits of an hour meter is that it saves a person from a lot of guesswork and allows him to schedule service based on the machines’ actual data. We initially discussed installing your lawnmower’s equipment, and later on.
