Black and Decker LSTE525 vs. LST522 String Trimmer

To keep your lawn spick and span, you mow it and use a lawn edger to clean along with the sidewalk.

However, you still have the garden beds and the narrow paths in your yard that your lawnmower cannot clean. Here is where the best string trimmers come in.

You need this versatile tool to clean hard to reach areas where a mower cannot fit in.

This incredibly portable and nifty tool can contour lawn edges and cut down grasses even in most awkward spaces in your yard.

What to Consider

Looking at a string trimmer, you would think that it is just a simple tool that you can quickly get from a garden shop. Little did you know that there are lots of things to consider in purchasing the best one that will fit your gardening requirements.

Cutting Width

The cutting width of string trimmers is measured in inches. Typical tools used by gardeners measure between 12 to 14 inches on average. This figure represents the space the trimmer can efficiently cut down grass without moving the unit. Therefore, the larger the cutting width, the more area you can cover in less time.

On the other hand, trimmers with shorter width sizes usually are smaller and a lot easier to maneuver. It provides more flexibility, especially if you need to work on tight and corner areas in your garden. Hence, the “bigger is better” rule may not be applicable when you’re buying a trimmer. It still boils down on the specific job you need to accomplish.

Convertibility

You can find string trimmers with convertible configurations nowadays. Most of these tools can be converted into an edger, allowing you to have two tools in one device.

This way, you will be able to save time and money from changing into another tool when working on your lawn. Just remember to choose a machine with at least one built-in wheel to make guiding easier when used as an edger.

Added Safety Features

Using power tools usually entails risks. To keep yourself safe, look for string trimmers with a solid safety guard around the head. A device that can have attachments is better.

You can easily convert it into a leaf blower or hedge trimmer. Even if this converted tool may not be as powerful as the standalone ones, it will still give you the functionality and convenience that you need.

FAQs

To guide you in selecting the best cordless string trimmer, here are a few more tips and guides about this functional garden tool.

How can I keep a trimmer line from sticking?

You’ll never find another tool more ideal for cleaning hard-to-access areas like around the fences, under benches, or irregular terrain than a string trimmer.

Gardeners often have the problem of the tool getting stuck when they restring it after taking the trimmer head apart. Here are some tips on how to prevent this from happening.

  • Correctly wrap the string by doing it evenly. Make sure that a level is complete before lodging on to the top of the other. It will avoid spaces in between to keep a smooth line.
  • Spray WD-40 on the trimmer line. It can prevent the strings from getting jammed. You can also use silicone spray or vegetable oil for this purpose.
  • Always use a line with the correct diameter. Check with the manual for the right size to ensure that you are using a string that is not too thick.

How do I correctly change weed trimmer replacement heads?

Replacing a cordless trimmer head is similar to the gasoline models. To do this properly, follow the steps below:

  • Turn the trimmer off and allow it to cool.
  • Wipe clean the trimmer head with a towel to remove grass and debris.
  • Detach the bump knob on the bottom of the trimmer head then pull the trimmer line spool out.
  • Insert a replacement head on the trimmer shaft.
  • Place the two loose ends of the trimmer line spool into the holes on the exterior of the trimmer head.
  • Finally, refasten the bump knob onto the head.

What size of strimmer line should I use?

The thicker the grass you need to cut, the thicker the string trimmer line you need to use. Strings with a larger diameter will help increase the line’s durability and power. Generally, for light trimming, you have 0.065-0.085 inches. For thicker grass and weeds, lines from 0.085-0.110 inch-range will be sufficient.

Meanwhile, if you need to work on more impenetrable underbrushes, you can use anything thicker than 0.110 inches. It is wise to check with the manual for the ideal right size to ensure that you are using a string that is not too thick.

Conclusion

The best thing about Black and Decker 20V power tools is that you can use the same battery for all these devices. You only need a single cell to power them all. Hence, you can save a lot of money by buying bare tools if you already own other Black and Decker 20V machines.
