Lawn care is not complete without trimming. That’s why you need a quality trimmer that can withstand the day’s work required for maintaining the grass. 

Lawnmowers take care of all the large patches in a yard, but the trimmer takes it one step further and cuts those hard-to-reach places. As a result, no lawn care endeavor is complete without trimming. However, not all trimmers are the same. 

In this review, you can find everything you need to know about finding the right trimmer and if the DeWalt DCST922P1 String Trimmer is the right fit for your lawn.

The DeWalt String Trimmer is an 8.5-pound, battery-powered trimmer for lawn care. It has a 13-inch cutting swath with varying speeds you can adjust yourself. There are two speed options to choose from: low and high. The low option can range from 0 to 4,600 rotations per minute (rpm). Meanwhile, the high-speed choice ranges from 0 to 6,000 rpm.

Why Have a String Trimmer?

A string trimmer is essential for lawn care. Even if you have a lawnmower, it cannot get more tedious spots. These areas include grass around fence posts, near plants and shrubs, and along the edges. A trimmer cleans up those hard-to-reach places so that the entire yard looks tidy and well-kept. 

What to Consider When Buying a String Trimmer

There is a lot to consider when looking for a new trimmer. However, this does not mean that the process should be complicated. The primary thing to look for is comfort. Since you are going to walk around with the trimmer a lot, the best thing to do is make sure you feel comfortable handling it.

  • Weight: The weight of the trimmer plays into the overall comfort. If it is too heavy to handle, then you cannot complete a quality trimming job. Find something with a weight that is easy to handle. A lighter weight means better control. 
  • Noise: No matter what kind of trimmer you get, you should always wear ear protection when operating it. However, you can find one that makes less noise for better ear safety. Typically, those powered by gas are louder than those powered by cord or battery. 
  • Safety features: You cannot forget that trimmers are blades that move quickly. There is a level of danger when operating them. It is crucial to find a trimmer with safety features that make you comfortable using it. A common feature is a shield that covers the string, which protects you from flying debris.

  • Power source: There are three general sources of power for string trimmers. These are gas, battery, and electric. You should pick the power source based on the yard’s size or the thickness of the brush. Gas is more commonly used for larger yards and thicker brush. Battery is usually the go-to for regular residential-sized yards. However, it is best to have a spare battery on hand just in case. Electric trimmers have attached cords. Though they are the cheaper option of the three, they can limit where you can trim.

Main Characteristics of the DeWalt String Trimmer

DEWALT 20V MAX String Trimmer (DCST920P1)

The DeWalt String Trimmer is an 8.5-pound, battery-powered trimmer for lawn care. It has a 13-inch cutting swath with varying speeds you can adjust yourself. There are two speed options to choose from: low and high. The low option can range from 0 to 4,600 rotations per minute (rpm). Meanwhile, the high-speed choice ranges from 0 to 6,000 rpm.

The trimmer comes with a 20-volt lithium-ion battery and a charger. Plus, there is a safety shield, and it only weighs 8.5 pounds, so it is perfectly safe for at-home lawn jobs. 


The DeWalt String Trimmer performs very nicely, especially for home lawn care. The shape of the handle makes trimming comfortable. Plus, it is easy to grip so that the cuts are steady and precise- or as precise as grass can be. The switch for the high/low features is close to the handle, so all you must do is flick your thumb to switch.

While using this trimmer, the overall noise was a lot lower than a gas-powered trimmer. There was also less vibration, which, again, allows for more precise cuts and better control. This also reinforces the overall safety of the DeWalt String Trimmer. 

The battery is decent. It can last for about a half-hour of non-stop trimming. This time can lengthen if the low mode is on. In general, though, the run time depends on the resistance of what is being cut. A stronger brush requires more energy, so the battery runs out quicker. The DeWalt String Trimmer cuts well for lighter to more medium strength grass and brush.

The features of the DeWalt DCST922P1 String Trimmer make it a safe one. The shield protects the user from debris, though it is essential to wear protective eyewear while using it. Additionally, there is little vibration so that the user can maintain better control. There is also a softer noise compared to other trimmers, which can better protect ears. Again, it is crucial to wear ear protection to be on the safe side. 

The grip of the handle also allows for better control. It has a “D” shape, which lets the user cut the grass from different angles. The handle also has a good grip for improved control. 


The overall cost of the DeWalt DCST922P1 String Trimmer is $187. This includes the battery and the charger. While it seems on the upper end of pricing, this trimmer offers safety features and quality precision that make the price worthwhile. Trimmers can range from $50 to over $200. Considering the quality, this trimmer is worth the extra money.
