WORX WG154 Edger 20V vs. WG155 Cordless String Trimmer

A lawn mower can do just enough for your garden. A perfect string trimmer can get into places that your lawnmower cannot reach.

It can also easily trim tall weeds and grass that could choke a mower.

If you also need a tool to manicure fence poles and tree trunks or keep walkway and garden edges spotless, then a cordless string trimmer is the perfect match.

What to Consider

There are some things you need to consider to know which string trimmer to get for your yard. It includes what type you need – do you need a curved or straight one?

Other factors include power source, functionality, power, safety features, to name a few. Let’s find out how these things can influence your decision to get that perfect string trimmer.

Curved or Straight Shaft

You can choose either a straight or curved shaft. For first time users, you might want to try each type at the hardware store or home center to know which feels more comfortable in your hand before buying one. Read on to see the difference between these two types of tools.

Straight Shaft

One can efficiently perform trimming using a straight shaft without the need to bend or kneel to reach areas for cleaning. Hence, taller users will find straight shafts more comfortable to use because this type is usually longer.

Curved Shaft

Curved shafts are bent halfway between the spinning trimmer head and the handle, which smaller and shorter users will prefer. It is easy to hold and maneuver, making trimming works more convenient.

Power Source

There are three types of string trimmer using different power sources. We will discuss each type below:


This type of string trimmers is the most common. However, they can be loud; therefore, users need hearing protection when using it. This tool provides extended use just by adding fuel into the machine

Corded Electric

It is the cheapest string trimmer, but it is only advisable if you have a long extension cord and outdoor outlet. So if you have a wide area to trim, you might need an alternative string trimmer type.

Cordless Battery-Powered

Cordless trimmers cut the same way as gas-powered models but can start instantly and without the loud noise. It would be wise to have an extra battery for your tool to avoid work disruptions.

Safety and Other Considerations

Using string trimmers involves some risks like accidental skin cuts due to debris. So even with the built-in shield, it is wise to wear protective gears such as boots, long pants, and hearing equipment when using gas-powered units.

Additionally, you can choose between a two-cycle or a four-cycle model. The two-cycle units might cost less, but you have to mix gas and oil in the required proportions. You should also put into considerations the gap between the cutting head and the trimmer shaft.

For the reason that, it is best to get a model with a minimal space with an easy-to-remove cutting head for easy cleaning.

How can I prevent the cutting line from breaking easily?

A trimmer line can quickly wear and break.  Cutting thick weeds and hard materials can wear down trimmer lines much faster. If you are using a line that has been around for five years or more and often breaks, then replace it. Use a fresh round line, since square and star-shaped lines tend to wear faster.

Why is the cutting line not feeding out?

If this happens, you might have a problem with the trimmer head or nylon line. Immediately stop the engine and unplug the electric trimmer and you can do any of the following:

  • Replace the spool when empty.
  • Clean the ports if clogged with dirt, grass, and debris.
  • Carefully rewind twisted lines. Cut out welded lines before rewinding the remaining usable lines.
  • Use the more durable anti-weld or anti-fuse lines.
