Weeds are hateful, can be problematic and we may end up in a never-ending fight against them. Weed killers are effective in eliminating stubborn weeds but can pose a threat to the environment and in some occasions, the lives of pets. This is where cheap and lightweight weed eaters come in.
What’s a Weed Eater?
Also known as string trimmers, trimmers, or weed wackers, lightweight weed eaters are pretty useful tools. Weed eaters are power tools that help cut down tall grass, thin brush, and weeds growing around your garden, lawn, or yard. They cut weeds at hard-to-reach places where your lawnmower may not reach. For instance, it can cut weeds on gravel surfaces or narrow driveways.
A typical weed eater features a shaft with a handle at the top end and a string cutting mechanism at the lower end.
Weed eaters have similar basic construction and use fast-rotating plastic strings to cut unwanted plants.

- Lightweight and flexible for fast weeding
- Inexpensive and simple to use
- Supports ease-of-use and offers convenience for high performance
- Eco-friendly and gets the job done faster
- Requires less maintenance and repair
Lawns differ in needs. The best grass trimmer for your lawn comes with multiple features to support its functions. With many brands on the market, it becomes important to find a reliable and reasonably-priced trimmer that guarantees better quality and a sensible warranty.
What to Look for When Buying Lightweight Weed Eaters?
When looking for the best lightweight weed eater, consider the following factors.
A weed wacker can be powered by gas or electricity. Electric trimmers can be either corded that needs to be plugged into the power mains or cordless using a rechargeable battery.
Cordless string trimmers are versatile but can only be used for a certain duration before they need to be recharged or the battery swapped to a full one. This is ideal if the battery has a run-time of at least 30-45 minutes.
With brands such as Black & Decker, you may get a battery that’s common to all tools in the same range. This means the same battery or spare batteries may be used for the lawn mower, the leaf blower and even the trimmer.
On the other hand, corded trimmers don’t need recharging. They’re limited by the cord length of course, and even though an extension cord can be added to extend the range, it may still not be enough for your needs.
Battery powered string trimmers are preferable for cutting weeds in your lawn in case you’re not likely to spend more than 45 minutes on the task. Otherwise, go for a corded electric option.
An electric trimmer is the lightest and cheapest while cordless models are the most convenient.
Both corded and electric trimmers are more eco-friendly than gas models and also less noisy.
Revolutions per minute (RPM) is the standard for rating the speed levels of lawn trimmers. It indicates a machine’s power and capability. A machine with higher RPM has better cutting power.
Consider a minimum of 7500 RPM if you want a powerful trimmer that can handle serious weed problems. Some models allow for speed control so you can choose between efficient battery usage and tough weeding action.
Grass trimmers differ considerably in weight, typically ranging from 4.5 to 6.5 pounds.
You need a lightweight machine to lower the strain on your arms and shoulders. Consider using a quality string trimmer harness to make work more comfortable.
Also take into account other factors, not just its weight, as a lightweight electric weed eater may not be as powerful as its heavier counterparts, and may be not strong enough for the job needed.
This is the width of the path a trimmer cuts in a single sweep. It is usually around 12 inches for a lightweight model.
Trimmers come in similar shape and design. The products feature a long shaft with a rotating head on the lower end and a grip at the upper end. A plastic line spins rapidly to cut weeds. Some models feature metal cutting blades but they are for though jobs and called brush cutters.
Double cutting lines help cut thick brush faster.
Some trimmers also feature shoulder straps, speed controls, anti-vibration, and ergonomic handles. The last two prevent operator fatigue which is fairly common for those who are not fit enough.
Buying a weed trimmer from the same brand as your other tools ensure brand compatibility. Some manufacturers allow for interchangeable battery use across multiple tools in the same range.
Other factors to consider are price and accessories.
Lightweight weed eaters are easy to maintain as they are cheap, easy to fix and due to their popularity, parts are widely available.
The best lightweight weed eater comes in handy when you need to spend a short time grooming your yard or lawn after mowing it as part of yard maintenance in summer. They offer low weight and acceptable performance on the budget to tackle low to medium amounts of weeds.
They exert less strain and less fatigue on your hands while working. Every weed wacker on our list is functional to bring down weeds where you don’t want them.
