Black and Decker LST140c vs LST136 String Trimmer Edger

String trimmers, also known as string trimmers, whipper snippers, edge, or lawn trimmers, are famous for giving you precise garden and lawn borders. On top of that, you can use this versatile gardening tool to trim along fences and walls, cut long grass, or even mow small-sized lawns.

What to Consider

More than just the price, there are things you need to consider before purchasing a string trimmer. Since you will be using it more than once each year, it is best to choose something that you are comfortable in using and will serve its anticipated purpose.

Petrol, Electric, or Battery-Powered

If you have a big lawn, then petrol-powered models are ideal, since you can quickly refuel and continue using even for hours. Corded electric and battery-powered trimmers may not be as powerful as gas-powered ones, but they are more convenient to use.

However, corded electric trimmers require a long extension cord, which may be dangerous to users. Cordless string trimmers are gaining popularity since these tools have greatly improved when it comes to performance over the years.

Straight or Curved Shaft

Trimmers with straight shafts are typically heavy-duty; hence, more powerful. It is long-reach and ideal for commercial use. On the other hand, trimmers with curves are commonly used for the domestic trimmer range.

Other Factors

Other things you need to consider are the size and shape of your garden. You also want to take into account the type of your garden grass, and other things in your yard like trees, garden beds, and walls. Some other factors to think about to make trimming activities less of a burden include the following;

  • Clutch – it stops the cutting head from spinning when the motor is not in use.
  • Safety Guard – helps reduce the amount of dirt, grass, and debris that fly around while cutting.
  • Handle – adjustable ones to suit small to tall users.

FAQs

How do I resolve line malfunctions?

When the trimmer line does not advance at all, there is something wrong with it or in the way it was loaded. Remember that every head trimmer has a limit when it comes to the diameter line.

Therefore, you must use the right size for each specific head. Always check the user manual of your trimmer to ensure that you use the proper line diameter for your tool.

Hence, it is wise to keep the instruction manual for proper guidance when it comes to tool maintenance.

Which is better, a trimmer or an edger?

It is always best to use the proper tool for the right job. For cutting grass in your yard, you must use a string trimmer.
