Lightweight weed eaters buyers guide

My article goes into the nitty-gritty of all things related to weed removal and lawn care. Going through the guide hereafter to truly understand what you need is the first step in gardening greatness.

Best lightweight weed eater buyers guide what to know before you buy?

Electric vs. gas

If you prefer low decibels in the noise department and only have an average size yard, you can easily get by with an electric weed eater that’s either corded or battery-powered.

But those who have a large property with thick weeds and don’t mind the noise of an IC engine in their hands, a gas trimmer is a must.

Similar to wood chippers, they offer you both options.

Corded vs. cordless

For folks with a relatively short backyard like 100 feet or so a corded electric trimmer will suffice. But if you have a larger property then a good battery-powered electric trimmer is a worthwhile investment.

The gas weed eaters are also cordless but are mainly built for the professional landscaping market.

Cutting width

The cutting width available in the market ranges from about 10 to 18 inches. For light yard work about 12 inches will be fine. But for larger properties go for a one with more than 16 inches.

Shaft style

A curved shaft trimmer like the Husqvarna 129C will give you more control. But it isn’t good for tight spaces like under trees and bushes.

On the other hand, a straight shaft trimmer will be able to easily reach such places but you’ll have to sacrifice some degree of control.

Weight

Gas-powered trimmers tend to be on the heavier side (15-20 lbs.). You need to have substantial strength to operate it properly.

But in general, electric ones are as light as 6 lbs. They are more efficient and easy for a lot more people to use daily.

Start systems

A smart start system means the engine will start in the blink of an eye and require little to no effort. It is especially convenient if you’re a beginner.

In the case of a gas trimmer, you must pull the rope with a decent amount of force to initiate the flywheel and start the engine. Which can be a very cumbersome and strenuous process.

Clear fuel tank

With a clear fuel tank, it is easy to keep track of your fuel usage. This can help you plan for refilling rather than running out on the job.

Luckily trimmers such as the Husqvarna 129C can help you do that with ease.

Trigger lock

Your weed eater starting on its own can give rise to a dangerous situation. It can cause bodily harm or destroy property if it turns on while being misplaced.

So it’s best practice to get one with a trigger lock. You can find it in most modern weed trimmers.

Battery life

If you have an average-sized yard of 100 feet or so the battery life of 20-45 minutes should be sufficient. The Makita XRU23SM1 provides just that.

But for larger yards weed eaters like the DEWALT DCST970X1 can be considered which has almost 3 hours battery life.

Guard quality

A good guard should be big enough and installed in the correct position to shield you from the debris of the trimming zone. It can even save you from the occasional cut or two.

It’s wise to buy a weed eater with a good quality guard like the WORX WG163 GT 3.0.

Warranty

Usually, most well-reputed weed eater brands provide a long warranty period for their products (3-5 years). During this time if any component stops working you can send it back and get a functional one back.

Weed eater FAQ

Can I keep the fuel for a gas weed eater stored when I’m not using it?

No, you shouldn’t do that. Without draining the fuel tanks gum deposit formation occurs.

When and how should I use a fuel-oil mixture?

The fuel-oil mixture has to be used with all two-cycle trimmers, like the Husqvarna 129C  in my list. You must maintain the right fuel-oil ratio for doing so which is generally 40:1.

How does the trimmer line break?

This happens if the trimmer head is close to hard objects such as bricks, rocks, fencing, etc.

What is the main thing to check before using a corded electric trimmer?

First, you should inspect the power-chord if it’s plugged in properly. Also, wrap any exposed wires with electrical tape.

Conclusion

Selecting the best lightweight weed eater is paramount if you want to maintain a beautiful well-kept garden. But to obtain the best possible results while doing so you have to factor in many aspects of your backyard.

If you have a relatively large backyard and some rough vegetation to go along with it. Then your best bet will be the DEWALT FLEXVOLT. This weed eater is purpose-built to handle the most stubborn of weeds.

But if you have an average-sized backyard you can easily get away with using lightweight electric ones such as the Makita XRU12SM1.

Picking the right one could well mean the difference between a stunning garden and a disaster. So you should go out back and see what your property truly needs.
