Types of Weed Eaters

Understanding the types of weed eaters is quite crucial in your selection process. They come in three different types: corded electric weed eater, cordless electric weed eater and gas-powered weed eater. Let’s take a look at each of them and the advantages and disadvantages you get from using them.

#1. Corded Electric Weed Eater

Corded Electric Weed Eater

Corded or plugin electric weed eaters are those that need plugging into the mains. Generally, corded weed eaters cost and weigh less compared to gas or cordless weed eaters. Most often, you’ll find them weighing less than 10 pounds, a feature that makes them much easier to handle.

Apart from the lightweight construction, corded weed eaters tend to be quieter compared to gas types. They don’t need tune-up and start effortless with the push of a button. These tools provide a limited range that needs you to be close to the power outlet. They’re perfect for use on smaller yards and modest landscaping jobs.

#2. Cordless Electric Weed Eater

Cordless Electric Weed Eater

As the name implies, these weed eaters come cordless. Instead, they’re powered by batteries to provide unrestricted mobility. Like the corded weed eaters, they start easy with the push of a button. Cordless weed eaters are most ideal in short to average size grass.

They tend to be heavier compared to corded weed eaters due to the addition of batteries. The size and power of batteries vary. Most often, batteries come in the size of 18V to 40V. However, some manufacturers are going larger by sporting battery sizes of up to 56V.

Unlike corded electric weed eaters, you get a limited run time averaging about 30 minutes. That means you need to recharge after power is depleted. The recharge time ranges from as little as 40 minutes to several hours depending on the model. Cordless weed eaters tend to be expensive compared to corded and gas-powered weed eaters.

#3. Gas-Powered Weed Eater

Gas-powered Weed Eater

Among the three types, gas-powered weed eaters pack the most power. That’s why they’re best for large areas that have tall grass and weeds. Gas-powered weed eaters are generally the heaviest. However, you can get those that weight less than 13 pounds.

These weed eaters need you to mix oil and gas, something that creates a lot of mess in your work. But some manufacturers have improved on their models to feature less mess and reduced exhaust emission.

Gas-powered string weed eaters need some effort to start. This is mainly achieved via a pull start mechanism. These weed eaters come more expensive than corded electric weed eaters.

You might also want to consider the topography of your yard. Uneven ground requires the use of a wheeled weed eater. This is to provide easy mobility and access hard-to-reach areas.

#2. Weight

In choosing the right weight for a weed eater, you generally want to first consider the time that you will be using the tool. Weight doesn’t matter a lot in jobs that require only a few minutes. However, if you’re going use the weed eater for a longer time, then you might want to choose a lightweight model for the task.

#3. Brand

It’s not advisable to purchase a weed eater that lacks a warranty. A warranty of 1 to 2 years is more common. However, brands such as GreenWorks have gone an extra mile to provide longer warranties of up to 4 years.
