Tachometers are designed to read the RPM of your engine but this is to a specific limit. As such, you need to be keen that the range of the tachometer will be in favor of your lawn mower’s engine. All you have to do is to ensure that the maximum readable RPM by the tachometer is greater than the max RPM of your mower.
It is important to note that most tachometers that you can get your hands on having a range of up to 10, 000 RPMs which is also what most engines are compatible with. Just to be safe, I’d recommend that you settle for the tachometer with the highest RPM reading you can get your hands on.
The build quality and design
Besides the RPMS yet another aspect you should pay close attention to is how well the construction is. After all, quality and performance go hand in hand, right?
Considering tachometers are to be installed in lawn mowers, chances that they are exposed to the elements such as water, heat, or dust are quite high. Because of this, it is of utmost importance that the tachometer you get be of a high a quality as possible.

The power capacity
Other than the durability and range, power capacity is yet another important feature worth looking into when choosing a lawnmower tachometer.

At the end of the day, whether the tachometer has a built-in battery or a rechargeable one, it’s important to prioritize one that has the best power management. Ensure you get as many cycles of use as possible before replacing or recharging the batteries.
Most of the tachometers nowadays normally have a memory function. Because of this, you owe it to yourself to invest in one of such to get the biggest value for your money.
Don’t get me wrong, however, digital memory isn’t meant to remember the latest recordings you take but instead, it functions to save the lowest and highest RPMs from your mower.
Whereas most tachometers have this feature, only a few have it on auto-save such that the readings are automatically stored rather than you having to do it manually.
This feature will be quite handy when you want to keep track of the RPMs of your mower and worth investing in.

For the lawn mowers, however, you’ll mainly have the digital ones which use optical encoders that determine the rotating speed of a shaft or a motor then converts them to digital signals. You can then take this reading on the LSD display.
Q: How can I test a tachometer using a Multimeter?
A: for you to do this correctly you’ll need to have the meter on AC voltage. Next, have the negative lead to the ideal chassis ground on the mower and the positive one to the tachometer wire in concern. Next, start the mower and once it is on the normal idle speed you should see a fairly constant reading on the AC voltage.
