Buying a String Trimmer Harness

String trimmers, AKA weed whackers, are incredibly useful yard maintenance tools that make quick work of grass and weeds in hard-to-reach areas. The problem is, these tools are notoriously large, heavy and awkward. Even newer, lighter models will make your arms burn after an hour or two of trimming in the hot sun.

That’s when a string trimmer harness comes in handy.

Worn over the torso, these harnesses take the weight of your string trimmer off your arms and distribute it evenly over your back, shoulders and core. I can tell you from experience as a nationally ranked powerlifting athlete, no matter how strong you are, you don’t want to do serious string trimming work without a harness!

When choosing the right harness, here are some things to consider:

  • Comfort and style: Designs vary greatly. A sling-style harness is more or less a single nylon strap that holds up your trimmer. While they’re often padded, they aren’t as comfortable for long jobs as a full, front-and-back padded harness.
  • Adjustability: Most string trimmer harnesses adjust, but the range of varies. Try one on before buying it, if possible, or make sure it can be exchanged.
  • Hook location: Depending on your height and arm length, the location of the support hook impacts how handy and comfortable that harness will be. Although some have adjustable hooks, many don’t. You don’t want a harness with a hook that’s too low or high.
  • Right-handed vs. left-handed design: Many harnesses easily adjust for right- and left-handed users, but not all. Some are only meant for right-handed use. If you’re left-handed, make sure the harness you buy will work for you.
  • Cost: This varies greatly, from around $12 to $200. Decide ahead of time what you’re willing to spend.

The Husqvarna Balance XT Trimmer Harness ($100) is one of the most comfortable, supportive and high-quality string trimmer harnesses I’ve seen.

Echo 4 Point Brush Cutter Harness Ecomm Via HomedepotVia Merchant

Best Echo String Trimmer Harness

In my experience, Echo makes high-quality yard tools, including string trimmers. The Echo Four-Point Premium Brush Cutter Trimmer Harness works great with most of Echo’s machines.

My favorite Echo string trimmer came with a flimsy plastic harness. This one is much better. It’s comfortable, extremely supportive and great for taller people like myself. Keep in mind that it’s only meant for right-handed use.

“I definitely recommend this harness for the Echo SRM-410U brush cutter,” writes a reviewer on homedepot.com. “It is far superior to the one that comes with it.”

Weight Absorbing Trimmer Strap Ecomm Via AmazonVia Merchant

Best Innovative String Trimmer Harness

The Good Vibrations Weight Absorbing Trimmer Strap might look like a simple, sling-style harness, but its built-in self-tensioning bungee system makes it a whole lot more. When properly set up and balanced, the system reduces the effective weight of your string trimmer to nearly zero, all without the bulk and expense of multiple pads and straps.

“It took just a couple of minutes to get everything together,” writes a verified reviewer on Amazon. “Very easy to attach to trimmer. Biggest thing is taking the time to balance the trimmer right. Do not get me wrong, it works and is comfortable no matter how you put it on. But with a little patience you can literally have it hanging from your shoulder where all you have to do is a slight swing of your arm to get a nice even trim.”
