Light weight, telescopic rod, limiting bracket, swivel head.
The handles are not adjustable.

The Black&Decker ST 1823 mower is designed for cultivation of cultivated lawns. With its help, it is convenient to mow young grass or dry vegetation left near flowerbeds and beds after winter. It is equipped with a spool, on which 9 meters of fishing line with a diameter of 1.6 mm are wound. The reel has a mechanism for automatically releasing the fishing line as it is spent. Rotating at a speed of up to 9000 rpm, the nylon thread cleanly and accurately cuts off all unnecessary, without crushing or damaging the stems of plants.

Trimmer handles are not adjustable. But this disadvantage is partially compensated by a telescopic rod that extends from the body or retracts into it. You can adjust the trimmer to your height or fold the tool into the most compact position before storing it in a corner or hiding it on a shelf.

The motor is at the bottom, closer to the coil. The head, together with the entire boom, can be rotated 90°, so you can not only mow grass in flat areas, but also make even edging of lawns along garden paths. To protect perennials that you do not want to damage when mowing grass close to flower beds and bushes, a wire limiting bracket is installed on the head.

The energy accumulated in a regular battery with a capacity of 1.5 Ah is enough for about 20 minutes of light work, such as mowing a young lawn (that is, about 1 - 2 acres). But if you use an extended battery (and all 18-volt batteries from the Black & Decker tool are suitable for this trimmer), then the battery life can be significantly increased. For example, a 4 Ah battery will last for almost an hour.

Light weight, telescopic rod, limiting bracket, swivel head, soft start, two batteries included.

Motokosa Makita UR 100DWAE, like other cordless trimmers, is designed for mowing lawns in small areas. It can be used as the main tool for lawn care (if its size does not exceed a couple of acres) or as a clever "partner" to your main lawn mower, able to get into the most inaccessible places in the garden.

The design of the tool provides maximum comfort for the user. The trimmer weighs only 1.9 kg and is well balanced: neither the front (with motor and spool) nor the rear (with handle and battery) outweigh and pull you forward or backward. The device turns on smoothly and without jerks thanks to the "soft start" function. A telescoping straight shaft and a comfortable front handle with an adjustable angle allow you to customize the brushcutter for yourself. Even small details are well thought out: there is a hook for attaching a shoulder strap, and LEDs are duplicated on the handle to indicate the battery charge.

The trimmer head rotates for edging. A wire fence can be installed on it, which serves as a restrictive bracket for protecting plants. As standard equipment there is a mowing head with a fishing line. But instead of it, you can buy a nozzle with plastic knives (article 198848-3 in the catalog of accessories for Makita lawn mowers). Due to the simple design, the head replacement operation can be done independently without contacting a service center.

The Makita UR 100DWAE trimmer is equipped with two batteries at once (with a capacity of 2 Ah). Each of them provides up to 19 minutes of battery life. Similar 10.8V CXT series batteries are used in many Makita tools. If you already have such a battery (for example, from a jigsaw, saw or screwdriver), then you can save a lot and buy the trimmer itself without batteries.

Light weight, swivel head.
The handles are not adjustable, not suitable for tall people.

The cordless Karcher LTR 18-25 trimmer is great for cutting lawn grass - especially the one that grows along fences, curbs and paths. It is light (weight about 2 kg with battery) and compact, so it can maneuver between flower beds, beds and bushes - where a full-sized lawn mower cannot fit. The width of the mowing strip is 25 cm. The vegetation is cut with a twisted fishing line having a diameter of 1.6 mm. The design of the trimmer provides for the possibility of installing a plastic knife, which is better than a fishing line, suitable for mowing thick meadow and swamp grass (it is purchased separately, the trimmer head with knives can be found in the accessories catalog under article 2.444-022.0).

The button on the side of the handle is designed to unlock the bar. It can be rotated 90° to bring the mowing head into a position perpendicular to the ground for lawn edging. The trimmer has no other settings: the handles are not adjustable, and the bar does not move apart. Therefore, this tool is not particularly suitable for tall people, because they have to mow the lawn in a slightly bent position. If your height is above average, then it is better to buy a Karcher LTR 18-30 cordless trimmer with a telescopic rod, the length of which can be changed to suit your needs.

The tool comes with a 2.5 Ah rechargeable battery. The manufacturer claims that it is enough for about 30 minutes of mowing (users in the reviews write about 20 - 25 minutes of work, depending on the stiffness of the grass and the density of the lawn). The battery has an LCD display that shows in real time the remaining charge and how many minutes are left until it is completely discharged. Batteries of this type can also be used with other types of cordless tools and garden equipment of the same brand: brush cutters, blowers, chain saws and even some vacuum cleaners.

Collapsible rod, two nozzles included (bladed knife and reel with fishing line), shoulder strap.
Stupid start button.

The Ryobi RBC-18X20B4F cordless trimmer has enough power to cope with household tasks of medium-sized lawn care in home gardens and summer cottages. It cuts well even long and juicy grass. And to fight weeds with thick stems or shrubs, you can replace the head with a fishing line with a three-bladed knife (included in the kit), which easily cuts even huge burdocks, cow parsnip and thin branches.

The motor, together with the gearbox and the battery pack , is on top. The trimmer comes with a shoulder strap that is similar in design to the harness used by professional lawnmowers. The suspension system distributes the weight of the tool (5.5 kg) on both shoulders and completely unloads the hands. The tool is equipped with a "bicycle" handle with comfortable rubberized handles. There are no special options for customizing the instrument for your height. Although the bar is collapsible(the trimmer can be folded in half for storage and carrying), it is impossible to adjust its length. On the other hand, due to the good balance of the tool, in most cases, only adjusting the length of the suspension strap can be enough.

Judging by user reviews, the 4 Ah battery that comes with the trimmer is enough for about 25 - 30 minutes of continuous mowing of a thick lawn (that is, it is better to buy an additional battery for a large lawn). However, few people will survive more than 30 minutes because of the tight start button, on which you need to constantly hold the index finger of your right hand during operation. If you already have a high-capacity Ryobi battery (batteries from 4 Ah to 9 Ah are suitable for the trimmer) from other tools or garden equipment, then you can save money and buy a “carcass” without batteries, which costs much less.

Brushless motor, two speeds, high capacity battery.
There is no provision for attaching a belt.

One of the key features of the DeWALT DCM561P1 trimmer is its brushless motor. As you know, such motors have a lot of advantages over traditional electric motors. A brushless motor is smaller and lighter, cooler, lasts longer and consumes less energy (a fundamental issue for battery-powered gardening equipment). The motor and gearbox are mounted below - right on the trimmer head.

The tool has a decent grip width - 33 cm. A thick and durable polyamide fishing line with a diameter of 2 mm is wound on the spool. The bar is made of aluminium. It is made from one single piece of tube and cannot be folded. A D-shaped handle is attached to the bar. You can change its height and position only with a screwdriver. The handle is made of high-quality and soft material, which is pleasant to the touch and does not rub the palms. But the complete absence of any opportunity to “attach” a belt to the trimmer is surprising. During work, you have to constantly keep a 4.3-kilogram tool in your hands on weight.

This trimmer has a very good reputation (even better than the newer DeWALT DCMST561P1, which has almost identical specifications). It works practically without vibration and does not annoy with loud sounds. Judging by user reviews, on a single charge of a standard 5 Ah battery, you can mow up to 10 acres of lawn, and it charges in just an hour and a quarter (this is the merit of the quick charger that is included in the kit). To save power, you can use a reduced speed of rotation of the trimmer head (there are two of them: 4600 rpm and 6000 rpm).

If you are already a happy owner of cordless tools of this brand and have 18-volt DeWALT batteries on hand, you can buy this trimmer without a battery and save almost 30%.
