Black & Decker LST201 String Trimmer vs LST300 Weed Whacker

Black + Decker makes interesting string trimmers that homeowners would need to handle their lawns.

It is not just for the home, as their models can also be good for commercial use.

The LST201 and LST300 models are closely related with some subtle differences. Since they cost the same, it can be hard to understand which is better.

However, our review guide should help you learn more and make the right decision about which to buy.

What to Consider

The Battery Performance

Since most of these tools will be battery-powered, look at the battery performance. The last thing you need is a model that requires recharging every few minutes.

Also, get an extra battery if possible. That extra battery means you can keep working as the other one recharges.

Tool Weight

You might be using the tool for hours sometimes. As such, there is a need to consider the tool weight also. Get a lightweight tool that can be good for your arm even if you use it for longer. Anything around 5 pounds should be lightweight for many.

The Speed

The speed is also good to consider as it determines the cleanliness of the cuts. Having a model that delivers on more speed will leave you with cleaner cuts for the edges.

Conversion Time

The chances are you will get these string trimmers also working as edgers. The idea is to make them more versatile as possible. The conversion time is how long it takes to convert it from a trimmer to an edger.

Look at models that will take only seconds with minimal or no tools required.

For almost the same price as the LST201, you can also buy the LST300 model. Some might not be sure what is the difference between the two. Below we look at the LST300 features to help you learn more.

Highly Versatile

One of the reasons people are going to choose this weed whacker should be its versatility. The manufacturer recommends it for trimming areas with overgrowth even after mowing.

Also, you can use the same for edging along the borders, flower beds, and sidewalks to leave them looking all clean.

All this is possible as it is both a trimmer and an edger at the same time. The conversion from one mode to another takes only a few seconds.

The Transmission

You can have the best power but without a nice transmission, getting that power down can be hard. This one has the POWERDRIVE transmission, which is responsible for delivering more power from the motor to the cutting string.

As a result, you will have the chance of getting the job done faster than before.

Easy to Start and Quiet

You might have used the gas-powered string trimmers before and noticed they can sometimes not be the easiest to start. Luckily, that problem is eliminated when you opt for the battery powered unit such as this one.

It starts faster and also remains quiet when working on a project. There is no need for using ear plugs.

Which is better between the LST201 and the LST300?

Where can you use string trimmers?

The string trimmers are for trimming the areas with overgrowth even after mowing. If the model is also an edger, it will be good for edging along the sidewalks, borders, and flower beds.

Is it easy to feed the trimmer line in an LST201 model?

Yes. This is because the model comes with the automatic feed spool that makes it easier to feed the line.


Both the Black + Decker LST201 and LST300 models are good in performance. Many also find them worth the money you spend on them. As such, you can go for either model and get a high-quality string trimmer for your lawn.

The best part is that both use the same battery system. It should be easy to get a replacement battery if the need arises.
