Stihl FSA 57 String Trimmer Review: 2023

Stihl’s FSA 57 String Trimmer is one of their most popular battery-powered string trimmers.

But I bet you are a bit hesitant. You love Stihl products but aren’t sold on battery-powered products.

And for good reason. Frankly, they have historically struggled to produce nearly as much power as you need. And your weird wimpy neighbor loves them.

Times are a-changing, though. Battery powered products are taking over. I mean look at the new F-150 Lightning – pretty sweet.

And Stihl is all over it.

Let’s see if Stihl still has it on this steal of a deal.

Let’s get started:

Why we review lawn tools

The reason we started this website in the first place was because we had so much trouble trying to find reasonable, understandable, honest reviews for lawn equipment. And it’s not cheap! After hours and hours of research, trying products and returning them, and messing up our yards – we started this site.

The world’s largest chainsaw manufacturer, the company moved some operations to Virginia in the 1970s and opened up their first factory dedicated to a single chainsaw. They have continued to master their craft and expand their product offers in the lawn care space.

Gas vs Electric String Trimmer

When purchasing a piece of lawn equipment in 2023 it’s important to understand your power source options. It basically boils down to gas or electric. Electric trimmers are typically easier to start and usually maintenance is a breeze. They also have less of a noise and environmental impact. Electric trimmers are usually a good bet for small to medium-sized jobs.

Trimmers powered by gas usually end up having more power and are more suitable for larger, more commercial type applications. This is mainly due to the issues the professionals have with keeping them charged. But not all of us are professionals, we just want a badass string trimmer from Stihl.

Stihl FSA 57 String Trimmer: Features and Benefits

Alright folks, let’s get into it. Today we are going to check out the power, ease of use, durability, and cost of this string trimmer. Throughout the post I’ll do quick comparisons to the gas counterpart, the Stihl FS 56 C gas trimmer. If you’re interested, we’ve compiled a huge list of the best Stihl string trimmers here.

Stihl does have a new Stihl FSA 45 String trimmer, which is kind of like this one’s little brother.

Power on the Stihl FSA 57 string trimmer

The Stihl FSA 57 trimmer can have its power measured in a few ways. The first of which is rotations per minute. Honestly, this is a really tough one to relate to as it takes a huge difference in the number of rotations per minute to notice a difference when trimming.

The power signal I am looking for is cutting swath, or width of the cutting path. This helps you understand just how powerful your electric Stihl weed eater is going to cut.

Definitely can tackle jobs like these!

The Stihl FSA 57 weed eater comes in at an 11 inch cutting swath. Honestly, a little disappointing. Don’t get me wrong, 11 inches is definitely enough for the average homeowner, but from Stihl I expected a bit more. For other electric comparisons, some of the Makita trimmers and EGO string trimmers run 13 to 15 inches. 

If you have a small to medium-sized yard, 11 inches is going to be perfect. But if you are the type of guy that likes to have more power accessible, then you may want to keep looking. 

Ease of use

What the Stihl FSA 57 weed eater lacks in power, it makes up for in ease of use. I mean the whole dang trimmer weighs 7.5 lbs – with a battery! Not only is this thing super lightweight, but it has a ton of features that make it very simple to use.

Some of the features on the Stihl FSA string trimmer are inherent to all battery powered trimmers. Namely – the battery power. Think about it, no more oil and gas mixtures or difficult cold starts with this. You just pop the battery, squeeze the trigger, and go. 

Another cool feature that makes this easy to use is the adjustable shaft. It can change in length with a pretty easy telescoping function. I’ve always found it easy to make trimmers as long as possible to extend your reach, especially if you’re tall like me.

It also comes with an auto-feeding head, which is pretty standard on most new trimmers these days. The last cool piece is the brush guard on the head, which comes standard on some of the Greenworks trimmers, Worx weed eaters, and Kobalt trimmers as well.

Durability is a common question I get with battery powered trimmers. Mainly because gas powered trimmers are just built differently. The commercial string trimmers in particular are made to toss into the back of a trailer and speed from one lawn to the next.

Residential battery-powered trimmers just aren’t. They have way more plastic components and can’t handle the same brush as most gas powered trimmers. Not true of all of them, but definitely true of the Stihl FSA 57 string trimmer.

One thing that really upsets me about the Stihl FSA 57 is that it doesn’t say anything about having a brushless motor. I’m absolutely shocked and frankly expected more from Stihl.

Brushed motors are still fine, but the standard in high-end string trimmers is a brushless motor these days. I think that tells you about all you need to know about this trimmer – Stihl clearly does not think it is a high-end trimmer.


Stihl FSA 57 Cost

Hate to say sad again so quickly, but sadly you have to contact your local Ace Hardware to get the price for this bad boy. Mine had it for $199, but I actually returned it :(.

The official review: Stihl FSA 57 String Trimmer

Well folks, I don’t do this often but I have to officially say that I am not a fan of this string trimmer. While it is super convenient, easy to use, and perfect for those with a small yard, it is definitely an apple that falls far from the tree. 

This product is simply not very durable and not up to the standards I would expect from Stihl. If you’re going to grab some battery-powered products, I’d find another brand like Ryobi or Greenworks that can give you more products along a single battery line.

If you’re going to go with Stihl, I’d get gas for now
