Finding A Corded Electric Strimmer

Corded electric string trimmer buyers guide section


We’ve reviewed some of our top picks for corded string trimmers available this year. Coming up next is our buyers guide to help you make an informed buying decision for your next trimmer purchase. String trimmers are designed for cutting grass, weeds, and other landscaping foliage for maintenance or beauty.

Why Use Corded?

If they’re the right tool for the job, you’ll find that there’s no need for you to get a gas or battery powered string trimmer. A corded trimmer is a much more cost effective option, when compared to the prices of their gas or battery powered counterparts.

Corded string trimmers operate the same as their gas and electric counterparts while providing the ability for unlimited trimming sessions while connected to a stable power source.

Will I Find The Cord Limiting?

For those of you with a small yard or a long extension cable the fact the trimmer is corded won’t bother you. It’s more likely to become a problem if you’ll be wanting to use it remotely, away from a power supply.

When choosing your new corded trimmer there are many factors to consider. One of the most important factors that you want to consider when choosing a corded trimmer is the amount of time that you are going to spend on your project and the project size. Keeping project duration and size in mind you can decide which strimmer is going to suit your needs.

There are many viable options available for corded trimmers (as you can see from the reviews above) that provide for you to purchase the right strimmer for your individual needs. If you’re working on projects that require a lot of time or intricate details in order to achieve the desired landscaping results, then you’ll want to consider a lighter weight trimmer to avoid fatigue while completing your project.

If you’re looking for your first string trimmer and need a bit more info head over to this wiki page.

Buying Factors

Many factors contribute to choosing your unique trimmer. Consider how long you feel that you will be able to work with your selected trimmer. Will you be more comfortable working with a lightweight trimmer for a longer amount of time or a heavier weight trimmer for a shorter period of time? These are all great questions to ask yourself before you buy.

Other factors to consider are the power behind your trimmer. If you have a tougher landscape to tackle you may want to look into higher performance strimmers to remove unwanted grass, branches, and brush.

Take a look at this list of important factors to consider when preparing for your next corded electric string trimmer purchase.


Consider the amount of power that your trimmer can deliver and choose between regular or high-performance models.

Cutting Lines

Many trimmers are available with multiple line features such as stronger lines, longer lines, and dual lines. Consider the landscape that you need to tackle in order to choose a trimmer with the best cutting lines for your individual projects.

Cutting Path

Related to the cutting lines is the cutting path. The cutting path is the width of the pathway that your strimmer is able to cut. An option with a larger cutting path will get your trimming job done more quickly but will not provide for precision landscaping.

Trimmer Weight

This is a major factor. As we discussed previously choosing a trimmer that you feel comfortable in handling is critical to the success of your trimming projects.

Try handling several strimmers with different weights to get the right feel for you before you buy.


If your ultimate goal is to create a well-manicured landscape or lawn, then you’ll definitely want to consider trimmers with added features to achieve your desired result. Accessories such as retractable cords, pivoting handles, and other available trimmer accessories can make all the difference in your next trimming project.

When shopping for your next corded string trimmer, consider the end result that you want to achieve and then purchase the trimmer that is most in line with the goals that you have set for your project.

Dual Functions

Some trimmers are designed as trimmers only for cutting grass and weeds, while others are built with dual functions to add edging and other features for precision landscaping.

Shaft Types

Trimmers are designed with either a straight or curved shaft. Straight shafts are more functional in tight spaces and provide an extended reach. Curved shaft trimmers are good for trimming open areas and wide spaces, but don’t provide as much maneuverability as their straight counterparts.

Important Legal Considerations for Operation

Some states like California have special legal considerations and requirements in place for the use of lawn and landscaping equipment and their related chemicals.

Be sure to check the rules and laws of your state or local governing authority to assure that you are complying with all relevant laws before choosing a trimmer and related chemicals or accessories.

California’s Proposition 65 is an example of one state that is very serious about its landscaping and related equipment use and laws and has implemented rules and regulations to protect the state’s drinking water from contamination that can be caused by an influx of certain chemical runoff from lawn, landscaping, and other equipment.

In order to be safe instead of sorry check your local rules and regulations before you buy.

Trimmer FAQ’s

How do I know which trimmer is going to be the easiest to use?

After comparing the features and functions of available trimmers, try to handle a few trimmers of different sizes to get an idea of what your personal trimming experience will be like. Choose a trimmer that feels most comfortable for you.

What is the main difference between curved and straight shaft trimmers?

The main difference between the two is reach and manoeuvrability. Straight shaft trimmers provide a longer reach and more manoeuvrability than curved shaft trimmers.

Why do I need to check local regulations before using my trimmer for landscaping my own yard?

Certain states have special rules and laws in place related to chemical use when operating lawn and landscaping equipment. The most notable case for this is California’s Proposition 65. Be on the safe side and make sure your state or municipality doesn’t have similar laws in place.
