Role of tachometers for lawn mowers

By installing a tachometer on the lawn mower, it helps you in monitoring the speed of the engine while working on the lawn. Most of the digital tachometers have data storing features that help to again maintain the rotations of the engine to the previous one.

While mowing a dense grass, the engine needs the most power or speed for smooth cutting so the digits on the meter show the vital rotations of the engine needed for thick grass. 

Once you know the limits of the mower’s engine, you can simply adjust the mowing speed for smooth working as per grass status and without overloading the engine.

Buying guide: Things to consider while buying the best tachometers for lawn mowers

When you have decided to buy a tachometer for your lawn mower, that’s not enough. Without proper knowledge you can never buy the best lawn mower tachometer. 

There are many factors that reflect the quality of the tachometer and its functioning and ultimately the life time of the product. You must need to consider these factors in a tachometer while buying one.

1. Quality

Quality of the product has a premium importance while buying any product online or in physical stores. Similarly, quality of the tachometers does have the same importance.

As tachometers will be installed on the mower so it will be exposed to dust, water, sun, cold, debris or woods, and much more. So high-quality tachometers could bear so many effects.

On the other hand, while mowing the lawn there will be a lot of vibration of the mower. Therefore, a premium quality tachometer is a major necessity to work in so many tortures.

Always check the quality of the material used in making the product for ensuring the long life of the tachometer.

2. RPM

As explained earlier about the RPM briefly, they are rotations of the working engine that could be any engine of a riding lawn mower, chainsaw, or any other machine.

Tachometers read the rpm of the engine but to a specific limit. The limitation of the tachometer to read the RPM is called the range of the tachometer.

Mostly, tachometers have the reading ability up to 10,000 rotation per minute that is almost compatible with many engines. But some engines have more than 10,000 RPM, so you will need a high range of tachometer for such engines.

It is best to buy a high range tachometer so it could be attached to various sized engines. 

So, always check the range of the tachometer while buying one for a lawn mower or any other engine.

3. Digital Memory

The memory of a tachometer does not mean that it will remember the previous working site or work type. Instead, digital memory features provide the memory of the minimum and maximum RPMs attained during any specific working period.

The great thing about this feature is its auto-saving that relieves you from the manual saving the data even if the power from batteries is cut off accidentally. The data remains safe and secure inside the device if the meter turns off by any accident.

Digital memory provides the data on the performance of any previous work. Consider the presence of this feature in the tachometer while buying one.

4. Power capacity

Power capacity or the battery life is a crucial feature that you should look at if you want to buy the best small engine tachometer for a lawn mower or chainsaw engines.

Two types of tachometers are present in market in terms of batteries:

  1. Tachometers with lithium batteries
  2. Tachometers with AAA batteries

Batteries included with the tachometers are of high quality, but it is good to check the batteries type. If any other type of batteries than lithium or AAA is included, never buy that tachometer.
