The fuel tank is translucent so you always know where you are with range, while the sure-fire fuel delivery system of prime, choke, and pull ensures the machine starts with ease every time.

The brushless motor provides a lot of power, performance, and durability, with a generous 16-inch cutting path to get the job done in double-quick time.

It features a large cutting swath at 18-inches, translucent fuel tank, and tap-n-go bump head for easy line feed. As it’s a four-stroke, it doesn’t need that fiddly oil/fuel mixture and runs solely on unleaded gas for a longer-lasting and more durable machine.

Swisher STP4422HO String Trimmer
First of all, and at the time of writing, if you’ve heard someone saying this is an overall bad trimmer, don’t be put off, as it’s probably unjust due to some misunderstandings on the buyer’s part. Swisher manufactures some seriously high-end commercial power equipment and this is no exception.
This walk-behind weed eater is a beast of a machine, featuring a super-strong, 4.4 horsepower, 160cc Honda engine. The off-set trimmer head is maintenance-free and will make it easy for you to negotiate those tricky spots in your (hopefully large) yard.
It offers you a merciless four-string/eight cutting line head, that will make short work of even the toughest weeds and grass. And to cap it all, it’s self-propelled, which will save you so much time and energy – especially if you’re trimming hilly terrain.
Reward: The most powerful walk-behind weed eater there is.
- Name to trust.
- Excellent build quality.
- Tough and durable.
- Large rear wheels.

How to Choose the Best Commercial Weed Eater
There’s a lot to take into consideration before parting with your cash on a pricey power tool – especially if it’s your first one.
Let’s take a look at the things you should be looking out for in your new commercial weed eater.
When it comes to commercial weed eaters, you generally have two types of power sources. They’re either going to be gas-powered, or they’re going to be a cordless rechargeable.
Corded battery-powered machines have no place on a list of the best commercial weed eaters and are only useful for smaller residential plots.
While it’s long been considered that gas versions offer the most power, in recent years the advancement of battery technology has begged to differ.
There are some particularly strong battery-powered weed eaters available that claim to offer the same torque of that of a gas trimmer.
These trimmers have numerous advantages. They need virtually no maintenance, they’re very easy to start with no priming or cord pulling required, they give off zero emissions, are super-quiet to operate, and they weigh considerably less than their gas counterparts.
However, that being said, they still can’t really compete with the sheer power you get from a quality gas engine.
They also have the obvious constraint of running out of juice eventually. They won’t be able to come close to gas-powered trimmers when it comes to range and run time.
Hence why for commercial purposes, the vast majority of weed eaters here are gas-powered.
They have either a two-stroke or four-stroke engine (or two-cycle/four-cycle engine).
Two-stroke engines offer the most power for their engine size. They’re often the go-to choice for professional weed whackers (landscapers).
They’re not without their drawbacks, however, as they need a measured oil and gas cocktail to run, can often be very difficult to start, and are considerably noisier than four-stroke engines.
Four-stroke engines don’t quite have the oomph that the two-stroke offers, but they are easier to start, only require gas to operate, and don’t spew out nearly as many fumes. This is advantageous in certain states where strict emission regulations are in place.
Regardless of which type of engine you choose, gas power tools are still noisy, they require a lot of maintenance and upkeep, and they’re not very kind to the environment.
Whether it be a rechargeable trimmer, a gas two-stroke model or a four-stroke version, It’s up to you which one you choose, but do take into consideration these points before you make the call.
It might also depend on the following factor, too.
Size of the Job
This is really quite simple – but it still needs addressing from time to time, especially as people are often prone to purchasing power tools that are serious overkill.
Suit the selection of weed eater to the size of the job it’s being bought to do.
If you’ve got a tiny piece of land, picking up a commercial-class trimmer is going overboard. Even if you really want it.
Likewise, if you’re lucky enough to own vast acres, a lightweight, corded trimmer you could use on your mustache or legs isn’t going to be up to the task.
Use your common sense here. It will save you time and money if your power tool is perfect for the job it needs to do.
Please note, I do not advocate using a garden string trimmer on facial or body hair.
Straight and Curved Weed Eaters
The eagle-eyed amongst you will notice that some weed eaters have a curved shaft, while others come with a straight shaft. What’s the difference? It’s much more than simply cosmetic.
These are generally more lightweight than straight shaft versions. They can be easier to handle depending on your personal preference. They’re also a lot cheaper.
These are more durable than curved shafts. They allow the user to access difficult areas and provide excellent reach and control. They’re more suitable for taller users, and/or if you’re cutting weeds for extended periods of time – which is why they’re generally favored commercially.
For a more detailed explanation of curved and straight-shaft trimmers, see the relevant question in the FAQ section below.
The size of your cutting head can make a big difference in the type of weed eater you choose.
As you might expect with commercial-class weed eaters, the larger the head, the better it is.
This simply means that you will cover more ground and get the job done faster.
Look for a trimmer that has a cutting head of at least 17-inches if you’re undertaking a commercially sized job.
Type of Cutting Head
How the cutting line is extended in the trimmer’s cutting head is another thing to consider before making your purchase. Generally speaking, you’ll find there are three types of cutting head.
The Fixed Head
This is the most common type in residential-class tools.
You start by feeding the line into the spool and cut the grass until it’s worn away and needs to be replaced. It’s the most time-consuming option and you won’t find it on a good commercial trimmer.
The Bump Head
It’s exactly what you think – you bump the head of the cutter on the ground to feed more cutting string through the spool. You replace the line only when it runs out, but it can get stuck and weld together if it’s not well designed and performing.
It’s also known as a bump-n-go and can save a lot of time if used correctly.
The Automatic Head
This head features a spinning motor that keeps the cutting string at a consistent length during the job. Excellent in theory, but it does come with its own limitations and can malfunction.
For commercial-standard trimming, I prefer using a bump-head as it offers you much more control and allows you to keep going by limiting the need to stop.
Again, it’s up to your personal preference and I’m open to having my mind changed.
Type of String
The market is awash with different types of trimmer string, and rather than extend this article for several pages, head on over to check out the best string trimmer line replacement spools of 2023.
You should find all the answers you need and the right type of string you should be using in your machine.
While it might at first seem like a string trimmer is lightweight, try lugging it around for a few hours and get back to me.
After even just a few minutes, these machines can start to become very heavy.
With that in mind, it’s important to select a weed eater you’re comfortable with and you can handle throughout the length of the job.
To be honest, most professionals will use a harness with the power tool, especially if in control of a gas-powered model.
There are lightweight trimmers available, but if you’ve got a lot of ground to cover you should consider investing in a good harness to shoulder some of the load.
Trust me – it makes all the difference.
Commercial weed eaters don’t come cheap – although there are certainly bargains to be had.
Again, I must stress that you should spend what you can afford, and only on something that fits the task it is required to do.
A $900 Swisher model is a waste of money on a backyard with not enough room to swing a cat.
What Is a String Trimmer Used For?
A string trimmer is mostly used to cut back on unwanted undergrowth in your garden or yard.
Its main purpose is to tidy up after you have mowed your lawn – as your lawnmower won’t be able to reach all the areas in your garden.
String trimmers are perfect for cutting vegetation around obstacles, close to brick, concrete or woodwork, or simply anywhere your lawnmower can’t venture.
String trimmers can also be used to edge a lawn – keeping a nice neat edge along walkways, flower beds, water features, or anything else you might have in your yard.
Do I Need a String Trimmer?
I always say that you don’t need one – especially if your yard is on the smaller side. For smaller plots of land, it’s much better to use a manual edger or long-handled shears to keep the weeds at bay and keep the grass in order.
However, if your yard or garden is much larger, then a string trimmer is highly recommended as it will make the job much easier and halve the time it takes to do it.
They’re also a big help for anyone who can’t do manual garden work – as using hand shears will seriously take it out of you.
What Is a Weed Eater?
Exactly the same as a string trimmer, trimmer, weed whacker, strimmer, or any other strange name they might be known by all around the world.
It’s a garden tool for cutting grass and groundcover that uses a flexible, monofilament line to chop down unwanted foliage.
Don’t confuse this machine with a brushcutter – which uses a rotating blade or chain and is a much more powerful machine.
They’re used for seriously heavy-duty jobs that include clearing denser grass, very tough weeds, and even small trees and shrubs.
Most residential homeowners will have no need for a brush cutter on their property. They should only be handled by someone who really knows what they’re doing.
How Do I Clean and Maintain My Weed Eater?
Weed eaters – particularly gas-powered models – need regular maintenance to ensure they’re performing at maximum capacity and last as long as possible.
You should clean your machine immediately after using it to cut grass or weeds, as if the debris is left to dry out it can be harder to remove. Use a stiff brush to clean anything off that shouldn’t be there.
Regularly check (and replace – if required) fuel and air filters if you’re using a gas-powered machine.
Air filters should be washed in detergent and hot water after every 10 hours of use. Rinse well and let it dry. Lightly soak with clean motor oil to prevent anything from getting sucked into the engine.
Fuel lines and primer/purge valves should be in good working order, with no cracks or leakages.
Replace the spark plug roughly every 25-30 hours of use. If it’s damaged, eroded, or blackened in any way – replace it immediately.
The throttle cable should be in good working order, with nothing impeding its operation. Tighten the handle and guard to ensure continued safe and comfortable use.
Replace the string line if required. See the article on replacing the string line for detailed information
Warning: remember to switch the machine completely off, empty the gas tank and remove the spark plug (if present) before attempting any maintenance on your weed eater.
What Is The Best Gas String Trimmer For The Money?
Without trying and testing them all, it’s difficult to say. Everyone has their personal favorites, and opinions differ wildly between professional landscapers.
If I was backed into a corner and had to choose the best gas-powered string trimmer – I would almost certainly go with a Honda.
They are more expensive than other models, but you get what you pay for.
Which Company Makes The Best Weed Eaters?
Take your pick between Honda, Husqvarna, DeWalt, Greenworks, Poulan Pro, and Black & Decker to name a small, inexhaustive list.
My personal favorites are Honda, DeWalt, and Greenworks. Let me know which you prefer and why.
Why Are Curved Shaft Trimmers Cheaper? What’s The Difference?
I touched on this debate in the buyer’s guide above, but for more information and an in-depth look at the differences between straight and curved-shaft trimmers (and why one is more expensive than the other) refer to the video below.
How Often Should I Use My Weed Eater?
Remember that all weed eaters are dispersing microplastic into the environment, so even if it’s not a gas-powered model it’s still having an impact on mother earth.
With that in mind, you should try to limit how often you use your trimmer – and always do your best to clean up after yourself when you do.
This is why it’s useful to purchase brightly-colored line, so you have a better chance of locating and disposing of as much of it as possible when the job is done.
It’s actually up to you and your lawn when you use your trimmer. Mowing and trimming tend to go hand in hand, so whenever your patch of land is becoming unruly, perhaps it’s time to bring out the big guns and cut it down to size?
What’s The Difference Between A Trimmer And An Edger?
A very good question and I’m glad you asked. However, instead of me opening that can of worms here, might I direct you to this rather informative article on that very subject.
Read my article about Edger vs Trimmer and you will find out exactly what you’re looking for.
In short – there is a big difference, and you should get one of each.
What Safety Equipment Do I Need To Use With a String Trimmer?
Another very good question and one I always like to touch on when talking about any kind of power tool.
Weed eaters – particularly the gas variety – tend to be very loud indeed. Especially two-stroke engines, or engines with a lot of power.
Are absolutely essential. There’s no ifs or buts about this – if you’re using a loud trimmer, you need to protect your ears.
Even if you can stand the noise for a while, you’re doing lasting damage to your hearing. This is particularly true of landscapers or regular trimmers.
Also, imperative. Even with a cutting guard, the very nature of these machines ensures that debris is going to be constantly flying everywhere.
Sharp objects, stones, glass, and even grass clippings can all cause serious damage and injury when launched through the air at high speed, and there have been fatalities. Wearing eye goggles is the very least you should do.
A harness is highly recommended for long periods of weed whacking. Don’t overlook the damage this job can do to your back.
When using a heavy machine, or tackling a large job, you’re going to need all the help you can get.
This could be needed for those of you working anywhere that’s public – especially if its along roadways. Most homeowners won’t need to go that far, but if you need to maintain a stretch of lawn along a busy thoroughfare – it’s not a bad idea to be clearly seen.
Protective gloves should always be worn – commercially cutting or not. The vibrations these machines give off can be very uncomfortable and can seriously damage and chafe your hands. The added grip they offer is also very advantageous.
For a more detailed look at all the protective things you should consider, read this article.
A beast of an article to cover these beast machines. Finding the best commercial weed eaters has not been an easy task, but I hope this piece has gone someway to pointing you in the right direction.
As for me, if I was forced to choose between them, I’d go for the DeWalt battery-powered model.
Yes, it’s not gas and purists would say it’s not commercial, but I think it’s a top-quality tool that will suit most homeowners right down to the ground they’re going to be cutting.
Let me know which machine you prefer and why.
Happy weed eating/trimming/strimming/weed whacking/whipper snipping!
