BLACK+DECKER 20V

BLACK+DECKER 20VBlack+Decker and strimmers are a match made in, well, it’s unclear as it has been a match for so long. As such this company has near perfected the humble grass trimmer and this 36V 2Ah battery model is a prime example.

Offering a 30cm cutting swathe backed by 8,500 RPM of speed, this is tougher than most cordless models. We popped this into Turbo mode and found it could take on weeds, light shrubs, and, of course, even long grass. The key is that E-drive tech adjusts the power to suit the job.

In real-world use, it’s barely noticeable, all you need to know and feel is that it’s cutting through whatever you point it at, right?

But should you want to make this last, say, on a grassy lawn, there is an ECO mode. We had this on as default for our usual lawn edge work and it was plenty powerful. If anything that 30cm cord length was a little on the long side.

Despite all the power, the running noise was low and the battery just kept going for well over 100 feet of garden. The company says it’s good for up to 3,750 linear meters on a charge, which does take up to two hours to replenish fully.

This gives you the battery and charger in the price, unlike some models, but it weighs a little more at 3.5kg. Yet it’s still comfortable to hold, features edging and strim modes that are easy to adjust, and comes with a telescopic tube to adjust the height.

Also, the auto cord feed works well and means no bending down and stopping when the 1.5mm cord snips.

Worx WG163.4 20V

Worx WG163.4 20VWorx has managed to create an impressive grass trimmer that fits into its 20V battery swap family of tools that still stays low on price. Despite the lower than-the-competition price, this offers a lot of features.

The one that we really enjoyed was the ability to edge trim with a handy wheel as a guide, this keeps you in a straight line and avoids catching the cord and snapping it on the edges of a patio. So, technically, this could save you even more money in cord replacement costs.

Another really useful feature is the ability to angle the head up to 90 degrees, we found that getting into the grass under low shrubbery areas is far easier, without you having to do your back in. While you don’t get an auto-feed there is Worx’s version, called Command Feed.

This basically means you have to tap a button to feed more of the cord through, which is easily done from where you are so this is nice for those that want more manual control without the hassle of messing with the spool itself.

You get a good hour of use out of this strimmer, which should be more than enough for most edging jobs. Especially with that large 30cm cutting swathe eating up grass fast. The handle can be angled but felt a little too close to the top, but that’s just a personal preference. For the price, this is a really impressive cordless strimmer and edging tool.

EGO Power+ ST1500XY

EGO Power+ ST1500XYThis is a big power battery model that finds a place between petrol power and battery ease. The result is the best of both worlds. You get a whopping 56V battery that powers a lengthy 38cm cutting swathe line all while keeping the weight down to an arm-friendly 3.2kg.

An included shoulder strap is a nice addition here to help make it feel light even for longer periods of use – we found it helpful for steady holding when intricate edging too. It feels solidly built and very sturdy – one that’s made to last.

Even the line is on the stronger side at a large 2.4mm thick. But even that can break, when too near the patio, but reloading is easy thanks to the “Power load” button which winds up the coil for you in about 10 seconds. Superb.

Battery life, even on the relatively small 2.5Ah battery is decent with a good half hour runtime. But if you’ve got a bigger garden, or want less charging, there is a 7.5Ah battery option that’s good for a whole 90 minutes of use.

Yup, this is every bit a pro-grade alternative to petrol that means less maintenance and noise. But, for that privilege, you pay a pro-level price too.

Running on the WORX 20-V MAX Lithium-Ion system, this trimmer can tackle any grass condition in record time and, since it’s cordless, you never have to worry about fighting with a power cord. A 12” cutting diameter makes a wide cutting path for efficient performance but is small enough to trim tight areas.

And the innovative Command Feed system allows for instant line feeding without having to bump your tool. The telescopic shaft allows for easy height adjustments and to switch this tool to an in-line edger, you simply have to turn the head and lock it in place.

A dual-function space guard protects your plants and flowers while also acting as an edger guide. And with an ergonomic design and a compact 5.3 lb body, it’s one of the easiest models on our list to carry or store away when not in use.

FAQ for portable grass trimmers buyers:

Is a grass trimmer the same as a strimmer?

A grass trimmer, or strimmer, is a useful tool for keeping your garden’s greenery tidy. Instead of a blade, they spin a nylon line at an incredibly fast speed. This makes them strong enough to make light work of grass, weeds, and plants, without the risk of damage to driveways, fences, and sheds.

How long do cordless trimmers last?

If you’re planning to replace a gas-powered trimmer, I’d say you should be aware of the battery life of these things. They typically last between 30 and 60 minutes of continuous use, and the batteries will take anywhere from 30 minutes to 2 hours to charge up (depending on if you have a fast charger or not).

Why does my strimmer line keep breaking?

Getting Too Close. The most frequent cause of line breakage is through contact with something in the garden.

What should I look for in a grass trimmer?

Look for trimmers with adjustable-length shafts or handles so you can customize the size to your height. Noise output: Gas-powered trimmers are always the loudest; corded electric and battery-powered trimmers are quieter. Even so, it’s best to use ear protection when running string trimmers.

How do you get rid of grass?

You can rent heavier equipment, such as a sod cutter, which will cut under the turf and slice it into strips. Roll up the strips for use elsewhere or just turn the sod upside down and let it compost. You can remove grass manually with a shovel, but the process is very labor-intensive and best for a small plot of grass.

Which is better: battery or gas trimmer?

Gas-driven trimmers are generally more powerful than battery-powered models. They are better suited for large jobs and can cover a lot of ground quickly. On the other hand, battery-powered trimmers are lighter and easier to handle, with much less vibration.
