Buying Guide

The above reviews are sure to have set you thinking about what all features you would like to have in the next battery-powered weed eater that you would purchase. In case you are still skeptical and still have some doubts, go through the buying guide below, and you are sure to receive all the answers to your questions. We have included some general information as well as the reasons why you should or shouldn’t go for a battery-powered weed eater.

Types of weed eaters

There are three types of weed eaters available in the market today: gas, battery, and electric. Although we would be mainly focusing on battery-powered weed eaters, we would also talk briefly about the gas and electric ones for comparison and help you understand the differences better.

Battery

For an eco-friendly option, it is best to go for a battery-powered weed eater. The battery-powered trimmer is a highly convenient option as it does not need to be dragged along with an electric cord. A battery-operated weed eater also does not require gas for its operation, and thus, you do not need to carry around a gas tank along. This makes the task of trimming and edging the lawn convenient and less tiring.

As the technology has been advancing, the runtime of the battery-operated options has been increasing and can last up to 60 minutes using continuously, much more if you have a small yard. These trimmers are also known for lesser noise levels, making them more comfortable for continuous usage. The maintenance cost is on the lower side as compared to the other type of weed eaters. Most options come with a charger and a battery it is better to check the inclusion of these accessories beforehand to avoid shopping for them later.

Gas

The weed eaters that are gas-operated are also quite powerful units. These types of weed eaters utilize a mixture of oil and ethanol-free gas for their operation. Depending on where you live, procuring the gas might not be easy. You would have to get the gas and fill the trimmer with it in case you run out of it in the middle of doing a job. This is one of the negative points as compared to battery-powered trimmers as with the battery ones; you need to recharge the battery for some time before resuming the job.

Although you can move around freely with the gas weed eaters, carrying the gas tank around can be time-consuming and tiring due to their substantial nature. The impact on the environment is also not good, and starting up, controlling, and maintaining can be difficult. The gas-powered weed eaters have higher noise levels.

Electric

The electric weed eaters are preferred by people who have a lot of extension cords in their lawns or have a small yard to maintain. These types of weed eaters need an easy-to-access outlet to work correctly and continuously. One also needs to be extra cautious while using these types of trimmers as a strike between the cutting line and the power cord can give you an electric shock and also obliterate the machine. It can also be dangerous to string together many extension cords; hence, it is better to go for another option in case you have a big lawn.

Factors to consider before purchasing

There are many factors to be considered before purchasing a battery-powered weed eater that suits the needs and requirements of your lawn. Some of these factors are as follows:

Weight

The battery-powered weed eaters tend to have very less weight as compared to the gas-powered weed eaters. They are light in weight and can even weigh less than ten pounds. This makes working with these trimmers quite easy and convenient. You would not get tired quickly after working with them and can use them for a long time.

Power

If you have been using a gas-powered weed eater, then you might be apprehensive about switching to a battery-powered trimmer. This is due to the power concerns that you might feel these devices might have. With advancing technology, even battery-powered weed eaters have become more powerful and can last for a long time.

Battery life

Most of the battery-powered weed eaters use lithium-ion batteries for their operation. These are mainly used as they are light in weight and can last for a long time, even on a single charge. In case you have a large lawn or high usage of the trimmer, it is always better to keep some backup batteries for use till the time you charge the ones that have run out of charge. This way, the work doesn’t get hampered in the middle.

Trimmer design

The weed eaters you will love to use are the ones that have an ergonomic design. Such devices ensure that the mass is evenly distributed throughout the trimmer. In other models, there might be more weight at the top as compared to the lower half of the device. Additionally, the controls of the device should be comfortable and smooth to handle. The units with straight shafts should be preferred as they can quickly transfer power from the machine’s motor to the lines that cut the grass.

Trimming area

The area of the lawn or the region that requires trimming is an influential factor to consider while purchasing a battery-powered weed eater. If you have a large trimming area, you need to ensure that the trimmer has a long battery life and can do the work for long periods. Similarly, if you have a small yard, even a relatively more straightforward and cheaper model is sure to get the job done quickly.

Easy access

In a corded or electric weed eater, you need to have access to outdoor outlets to work with the trimmer efficiently. This can be quite frustrating at times when you do not have enough outlets outdoors or if the cord is not long enough. With a battery-powered weed eater, you face no such problem, and you can easily trim the whole lawn with the trimmer.

Uninterrupted

If you are looking for a trimmer in which you do not have to stop in the middle of trimming a large lawn, it is better to invest in a weed eater that has long battery life. In case you have a relatively small lawn and can charge the batteries in the middle, you can always go for a corded unit.

Guard quality

Although the guard is an underrated component in a trimmer, if you do not want to have debris, small rocks, or bits of plants to launch at your legs, it is vital to ensure that you buy a weed eater that has a high-quality guard. This is particularly helpful if you live in a humid or hot area and do not like to wear jeans or full pants while trimming the lawn. It also protects you from any unnecessary cuts while working.

Feed reloading features

One common point of every weed eater is that the trimmer line needs to be replaced after a certain point in time. Depending on what brand and model you choose, this can be an easy or difficult task for you. The thicker the trimmer line, the longer it will sustain and would not have to be replaced that often. But one needs to note that these can be heavy and need more amount of power.

Warranty

Most of the well-known weed eater brands in the market give an extraordinary amount of guarantee for their products. If you are looking for a trimmer of high quality, it is best to go with a brand that can give you an extended warranty. Since the industry standard is one year, you should look for options that can provide you with the same or a better warranty. It is also essential to ensure that the after-sales service of the product is excellent and reliable.
