Best Weed Eater Buying Guide

What you need to know about a weed trimmer is usually found in its specifications. Features like cutting swath, attachment capability, and battery capacity set weed eaters apart from each other. There are other ways to permanently get of weeds in your lawn.

Battery Capacity

On average, 15 to 20 minutes of run time in enough to manicure a ¼ acre lawn. Li-Ion battery-powered weed eaters can offer between 15 to 60 minutes of continuous use.

However, if you have a particularly larger yard, you always have the option of swapping a couple of batteries. But, depending on the model you have, getting an extra battery can be expensive. Still, if you are tackling larger projects very often, a backup battery is a good investment.

Typically, it takes between 30 minutes to 2 hours to recharge a weed eater battery, depending on the type of charger you have. Some brands sell fast chargers, but they usually cost a bit extra.

Battery Interchangeability

You should be able to use your weed eater’s battery with other outdoor power tools from the same manufacturer. Most OPE (outdoor power equipment) manufacturers design their batteries to be compatible with all of their power tools.

Having a collection of tools on the same platform can be very cost-effective. So, if you already have a cordless power tool in your garage, consider buying a weed eater of the same brand.

If it’s your first time buying a cordless tool, it’ a good idea to see what other cordless tools a brand has to offer, and not just their weed eaters. Again, batteries can get very expensive, so if you choose to go with a reliable and trusted manufacturer, brand loyalty can indeed pay off.

Battery Type

There are two types of batteries: Ni-Cad and Li-Ion. Ni-Cad batteries models are still available, but they have become obsolete, more or less, so buying a Ni-Cad powered model or a Ni-Cad battery is a poor investment.

However, many battery-powered weed eaters accept both Li-Ion and Ni-Cad batteries, so, if you have an old Ni-Cad battery of the same brand as your weed eater, it may still be useful.

Li-Ion batteries have become the standard. On average, they are 50% lighter than Ni-Cad batteries. A Li-Ion battery offers a consistent power output for as long as it lasts.

But, they have a finite lifespan. If your weed eater uses a Li-Ion battery, you’ll have to replace it after 3 to 5 years of use.

Li-Ion batteries slowly drain over time. So, it’s best not to leave the battery on the weed eater when you are not using it. It will drain even when if it’s off, but slower.

If it has been a couple of weeks since you last used your Li-Ion battery, you will probably need to recharge it. If you can, store your Li-Ion batteries indoors.

Battery Voltage and Amps

Li-Ion batteries used on weed eaters range from 18V to 82V. Tougher jobs require more power. If you want more power, go with higher-voltage batteries. To determine how much voltage you need when buying a Li-Ion battery, check your weed eater’s product manual.

Generally, the amp-hours (Ah) of a battery can tell us how long it can hold a charge. The more amp-hours it has, the longer the run time.

Types of Weed Eater Shafts

Weed eaters come in two different styles—straight shaft weed eaters and curved shaft weed eaters.

Straight shaft weed eaters are more common than curved shaft models. A straight shaft weed eater allows you to handle tight spaces and hard to reach corners. This type also works well under fences. They are the better option for taller users since they offer a longer reach.

It’s not uncommon for a straight shaft weed eater to have a telescoping shaft. A model with a telescoping shaft is great for those who prioritize comfort.

As far as battery-powered weed eaters go, curved shaft models are not very common. This type of weed eater is great for weed and grass trimming in open areas. However, they are usually not the best option for small corners.

Generally, curved shaft weed eaters are easier to handle because they are lighter than straight shaft models.

Cutting Path

The cutting swath can be anywhere between 10″ and 18″, but the average weed eater has a cutting swath of 12″.

Weed eaters in the 12″ range can keep the speed up with less torque. They tend to be more efficient. But, the wider the range, the less time it takes to do the job. Professionals generally prefer to use 15” weed eaters.

The cutting path of a weed eater should be narrow enough for you to be able to use the trimmer in small corners, but it also needs to be wide enough to clear a large area with one sweep. So, it’s best to choose a model in the 12” to 15” range.

Line Diameter

The line gauge of a weed eater can be anywhere between 0.060” and 0.105” in diameter. Some professional-grade models use lines even thicker than 0.105” but they are not common.

Thicker lines offer more cutting power. They also don’t break so easily. So, if you want to spend more time trimming the lawn and less time changing lines, it’s best to choose a model that has a line gauge capacity of at least 0.080”.

Line Changes

Changing the line can be a very frustrating process. The best battery-powered weed eaters take advantage of simple and intuitive line changes.

Ideally, you will be able to change the line in just a few minutes. However, if you are not happy with how long the process takes, you can always upgrade the head.

It’s best to go with a model that uses a speed-feed system. It allows you to change the line without removing the spool, so you’ll never have to deal with a jumpy line and tangles.

Speed

A weed eater that can spin the line at more revolutions per minute (RPMs) will get the job done faster. Most cordless weed eaters fall in the 6000 – 9000 RPM range.

If a weed eater has variable speed control, it lets you adjust the speed at which the string spins. Weed eaters with variable speed control are more versatile than single-speed weed eaters.

For instance, if you’re dealing with long grass or tougher weeds, you can choose a higher speed. For light-duty weed whacking, you can choose a lower speed. Lower speeds also allow for a longer run time.

Attachment Capability

Lawn care professionals typically have dedicated tools for edging, trimming, and hedge trimming. If you get a model that uses interchangeable heads, you can get all those tools in one.

Some weed eaters can cover everything from brush cutting to blowing. And, if you get a weed cuter that has a universal connection, you will be able to use attachments from other manufacturers.

Balance

The lighter a weed eater is, the easier it is to work with. But, the distribution of the weight is just as important as the weight itself. A weed eater should be heavier at the top, or the weight should be evenly distributed.

Using a weed eater is more difficult if most of the weight is in the cutting head. You’ll become fatigued quickly and you may even have a hard time holding it steady.

Noise Level

The best battery powered weed eaters are much quieter than gas-powered models, but they are still noisy tools. The level of noise a weed eater makes is measured in decibels (dB). Before you buy a weed eater, you should check your local noise regulations.

The average battery-powered weed produces 86 dB of noise at full throttle. Louder models are rated at 92 dB and more. Even if you buy a quieter weed eater, it’s a good idea to wear hearing protection. These Mpow 035 earmuffs are a good and affordable solution.

Takeaway

Of all the weed eaters on the list, the Ego ST1521S String Trimmer does the best job of balancing power and efficiency. It performs just as well as a quality gas-powered model but offers much more convenience. And, considering all the features it has to offer, the Ego ST1521S comes at a very attractive price point.
