A different take: 7 Signs That You 're Cutting Your Grass Too Short

If you're in the market for a cordless grass cutting machine, you've got plenty of options to choose from. Our research has yielded some top picks that are worth considering.

We've got a range of models that cater to different needs, from light-duty options for small yards to heavy-duty models that can handle everyday use. For example, the Echo eForce DSRM-2100 56V Battery-Powered String Trimmer is a heavy-duty model that's perfect for tackling larger areas.

Here's a quick comparison of our top picks:

We spent most of our testing time at a rural property in New Hampshire with extensive trimming needs. This property had 187 feet of stone wall, 182 feet of split-rail fence, and 180 feet of garden fencing that needed trimming.

We also tested the trimmers on a Los Angeles hillside covered with 3-foot-tall grasses, saplings, and nettlesome thistles. This was a challenging test that pushed the trimmers to their limits.

We tested the trimmers' ease of use, balance, ergonomics, handling, and noise in various scenarios, including trimming between rose bushes, down the edge of a driveway, and around fire pits. We also tested them while cleaning up around trees, under mailboxes, and between garden beds.

To compare the trimmers' run time and power, we took them to an overgrown field and cleared giant swaths of thick grass and dense weeds. This test drained the batteries and gave us a clear picture of each trimmer's capabilities.

The Ego ST1521S Power+ 15" String Trimmer with Powerload is a solid runner-up choice. It's nearly identical to the Ego ST1511T, our main pick, but lacks the telescoping shaft and quick adjustment on the handle.

The ST1521S still packs plenty of power, with the same 56-volt brushless motor and heavy-duty 0.095-inch line as the ST1511T. This means it can easily cut through grass and weeds.

A key difference between the two models is the shaft design, which doesn't telescope on the ST1521S. This might make it slightly less versatile for users with varying body heights.

The ST1521S also has a slightly different trigger design compared to the ST1511T. Despite these differences, it still offers long battery life, excellent power, and easy line changes.

If you can't get your hands on the ST1511T, the ST1521S is a reliable alternative. It's priced similarly to the ST1511T and sometimes even more, so it's worth considering if you need a string trimmer in a hurry.

Here's a quick comparison of the two models:

The ST1521S is a great choice if you can't find the ST1511T, but it's worth noting that the ST1511T is our top pick for a reason!

The Ego ST1611T and ST1623T are both 16-inch models, cutting a swath an inch larger than our top picks. This added length comes at an extra cost, which may not be noticeable unless you're doing extensive work with your trimmer.

The Milwaukee 2825-21ST Fuel String Trimmer is attachment-ready, but it's also quite pricey, coming in at around $350. This is a significant jump from the other models we tested.

The Echo DSRM2600 eForce 56V X Series String Trimmer has a durable feel and is a nice three-speed model. However, its small debris guard and high price tag are notable drawbacks.

The Ryobi RY40290 has been discontinued, along with several other Ryobi trimmers we've tested. This may be a concern for those invested in the Ryobi brand.

The Ego ST1623T Power+ Powerload String Trimmer automatically feeds out the line, making it a convenient option. However, it didn't always maintain the advertised 16-inch length.

The DeWalt trimmers we tested were light and comfortable to use, but they lacked the run time and power of our top picks from Ego.

The grass cutting machine cordless is a game-changer for lawn maintenance. It's lightweight and easy to maneuver, making it perfect for small to medium-sized lawns.

You can expect to get up to 45 minutes of runtime on a single charge, depending on the model and usage. This is more than enough time to tackle a decent-sized lawn.

The cordless design also means you don't have to worry about getting tangled up in cords or dealing with extension cords. It's a huge convenience factor that makes lawn care a breeze.

The Ego ST1511T Power+ 15" is my top pick for a string trimmer. This model far outperformed other brands in run time and power.

Its telescoping shaft and handle make it easy to adjust and comfortable to use, even for extended trimming sessions. I've seen people struggle with trimmers that are too heavy or unwieldy, but this one seems to get the job done without breaking your back.

The weight of this trimmer is 11 pounds, which is manageable for most people. I've used trimmers that are much heavier and it's like trying to wrestle a bear.

This trimmer has a 56-volt brushless motor, which gives it the power to slice through grass and weeds with ease. You can also adjust the speed to suit your needs, which is a nice touch.

Here are the key specs for the Ego ST1511T Power+ 15":

Overall, the Ego ST1511T Power+ 15" is a solid choice for anyone looking for a reliable and powerful string trimmer.

Auto-feed and bump feed string trimmers are two different types of trimmers, with auto-feed using centrifugal force to release trimmer line with every trigger pull, and bump feed requiring the user to manually disengage the spool lock by "bumping" the trimmer head on the ground.

If you're experiencing line breakage, it's normal, especially in harsh terrain or when edging. To reduce breakage, keep the underside of the trimmer head clean, ensure the cutting blade is clean and exposed, and avoid direct contact with hard surfaces.

The guard on your string trimmer is a safety feature that prevents debris from being flung towards you and helps reduce line breakage. Operating without a guard will void your warranty and reduce the motor's lifespan.

If your line keeps unraveling, it's likely due to the spool lock not being properly engaged. In auto-feed trimmers, this can be caused by a faulty mechanism, while in bump feed trimmers, it's often due to the user not disengaging the spool lock correctly.

Reduced gear in a string trimmer means the motor is working harder to generate power, which can lead to increased wear and tear on the motor. This is usually indicated by a slower speed or increased vibration.

You can use a thicker diameter line than recommended, but be aware that it may not perform as well and may be more prone to breakage.

The Ronix 89 Lasting series battery can be charged in just 1 hour using a fast charger and provides up to 55-60 minutes of runtime.

The Greenworks 24-Volt string trimmer features a 24-volt motor and a 4Ah battery, giving it enough juice to handle light-duty work for up to 45 minutes.

The Echo DSRM-2100 has a two-speed design that allows for finesse trimming and can handle dense tall weeds, but the 2.5Ah battery may need to be upgraded for longer jobs.

Here's a comparison of some key specs for popular cordless string trimmers:

The DeWalt 60-Volt string trimmer has a large 17-inch cutting width and can be converted to a leaf blower, hedge trimmer, or pole saw with optional attachments.

The motor of this grass trimmer is a strong one, capable of producing 20V of DC power from its lithium-ion battery.

This allows for a high rotation speed of 8500 RPM, which is considered the most effective among all trimmers.

This speed is essential for efficient and safe operation, making it perfect for tackling those annoying weeds.

The key specs of a string trimmer can make all the difference in how well it performs. The battery capacity is a crucial factor, with most trimmers featuring lithium-ion batteries ranging from 2 to 8 ampere hours (Ah). This translates to between 20 and 45 minutes of runtime on a single charge.

The voltage of the trimmer is also important, with some models featuring higher voltages like 36v or 56v. This can result in more powerful cutting capabilities. The weight of the trimmer is another consideration, with some models weighing as little as 5.5 pounds or as much as 12.95 pounds.

Here are some key specs to look for in a string trimmer:

The runtime of a trimmer can vary greatly depending on the battery capacity and voltage. For example, the Greenworks 24-Volt, 13-inch Brushless Battery-Powered String Trimmer features a 4Ah battery and can run for up to 45 minutes.

A thicker cutting string, also called a line, is a must for tackling taller weeds. This thicker line can cut through heavier vegetation with ease.

Thinner lines, measuring 0.065 to 0.080 inches, are better suited for trimming grass and defining lawn borders.

For slicing through thicker weeds, I recommend using a 0.095-inch line or larger. Thicker lines require more power to spin, which often means a shorter runtime.

Thicker lines, however, hold up better for lawn edging tasks near hard surfaces like walks and driveways.

The design of the grip is especially important on a string trimmer – a good one can help you maintain good posture and avoid straining your back.

Most models have either a dominant hand grip at the rear of the trimmer, or one that’s built into the shaft, just below the motor.

A rear handle design provides more leverage for controlling the head, but I prefer a mid-shaft grip, which does a better job helping you carry the trimmer’s weight.

Most trimmers also have an off-hand grip that you can tilt forward or backward to adjust the angle of the string at ground level.
