Short Overview: Our Recommendations

Best Walk Behind String Trimmer: Remington RM1159

With a 159cc engine and 22-inch cutting swath, the Remington RM1159 has the greatest capacity to cover 5 acres of land in more or less 60 minutes.

This wheeled grass trimmer assures you get to clear even the toughest and tallest weeds on your property. This is all thanks to a powerful engine that can create a clean and consistent cut.

Runner Up: Southland SWSTM4317

Southland SWSTM4317

On the other hand, the Southland SWSTM4317  has booked its spot for the best budget-friendly model. Despite being the most lightweight on this list, this compact unit still has specifications ideal for heavy-duty trimming.

Additionally, this model is an affordable and convenient alternative to handheld tools. The Southland SWSTM4317 may not be as powerful as the other products on this post, but it doesn’t come short on ergonomics and cutting capacity.

Time for our favorite part! In this section, we are going to explain every major detail, appealing features, assets, and disadvantages.

In this product review, we focused on assessing the cutting swath, trimmer line size, engine power, maximum yard size, weight, and operating time.

When you combine these factors, you will be able to choose the right model.

1. Top Pick: Remington RM1159 Walk-Behind String Trimmer

Remington RM1159

A 159cc OHV gas engine powers up the Remington RM1159 Walk-Behind High-Wheeled String Trimmer. In this way, its 4-cycle gas engine boosts your power in killing tall, tough weeds.

To make things way easier, a 22-inch cutting swath trims around garden beds, fences, and other landscaping borders.

The trimmer line size is a standard 0.155 inches in diameter, so this shouldn’t pose any problem when changing strings. This line size is resilient enough to stand up to a lot of hard work.

A word of advice: learn how to change the trimmer line because you might do it often when you spend a lot of time cutting against barriers. Don’t worry, the tool’s design makes this additional task worry-free.

What we liked best during our test is that the off-set trimmer head aids in cutting hard to reach areas.

Moreover, it is a user-friendly tool because the 14-inch ball-bearing wheels assist in maneuvering with ease through rough terrain or thick bush. This large size can surely cope with uneven ground.

However, at 78 pounds, the Remington RM1159 Walk Behind Wheeled string trimmer mower is the heaviest model on this list, so it may somewhat be difficult to store.

But know that most big units are normally designed with the best features.

Besides, it has a running time of 60 minutes and a 5-gallon fuel tank capacity. Subsequently, you can cover areas up to 5 acres.

To our delight, it has an extraordinary cutting height of 1 to 6 inches. This is perfect for uneven areas since you can adjust the height depending on how long the weeds are.

As for the ergonomics, the Remington RM1159 comes with a comfortable folding handle for convenient transportation and storage.

Recalling our tests, we’ve seen how this wheeled trimmer easily handled 5-foot tall weeds without having a jam. In addition, the model is easy to start, so you only have to crank up on the first pull.

If you want to include edges, know that his model only trims parallel to the ground surface. This means you can’t cut into the crevice between a yard and the pathway.

To be fair, this machine is specifically designed to face rough stuff. Hence, you might need to mow afterward if you want manicured outcomes.

Still, the Remington RM1159 Walk-Behind Trimmer can create intricately shaped spaces. This is due to the off-center positioned trimmer head.

We’re pretty sure you will love this unit’s ability to change the height of the cut. Using a simple lever on the handle, you can choose from the three different settings.

As proven by these impressive attributes, this wheeled weed whacker is powerful enough for tackling any terrain.

In a nutshell, the Remington RM1159 Walk-Behind High-Wheeled String Trimmer is a user-friendly unit that makes big jobs seem small and help you clear the tallest, toughest grass and weeds. It has a powerful engine that makes a consistent and clean cut.

Southland Outdoor Power Equipment SWSTM4317

The Southland SWSTM4317 Wheeled String Trimmer has an onboard trimmer string cut length guide that ensures you get a 17-inch cutting swath.

What’s likable about the model is its multi-streaming trimmer head that accepts 0.095 inches and 0.105 inches. In this way, you choose the string that is appropriate for your trimming job.

As a bonus, there’s an onboard trimmer string storage that keeps your extra string handy at all times.

At 43cc, this model has the smallest engine outcome, but this is because of its compact size of 39 pounds. Despite having a 2-cycle engine, it is the most lightweight model we’ve reviewed.

Due to the model’s small size, the Southland ​SWSTM4317 wheeled weed Trimmer won’t need a lot of room for storage. 

The handle doesn’t fold down, but the whole unit is compact enough.

For comparison, this unit provides over 35% more torque versus the typical 25cc handheld string trimmer.

With a running time of 20 minutes, you can go through a yard size of up to 2 acres.

For ergonomics, the tool comes with a 20-degree to 30-degree trimmer head swivel that can cut along a fence or wall in a straight line.

Likewise, there’s a 5-degree to 10-degree trimmer head bevel for precise edge trimming along barriers, boundaries, or obstacles.

The Southland SWSTM4317 is also equipped with an adjustable height ergonomic loop handle with spring-loaded thumb actuated throttle control that provides extra comfort. Therefore, this model lessens user strain or fatigue.

The 12-inch durable ball bearing wheels allow the trimmer to handle rugged and rough areas. As a result, this unit provides so much maneuverability that it can lead you to odd spaces and tight corners that movers can’t reach.

We assure you, this wheel diameter is apt for the machine’s size. Subsequently, the sturdy wheels are wide enough to retain stability in difficult conditions.

We also discovered that the Southland SWSTM4317 has an optional blower and edger attachments.

This is where things get more exciting. The push grass trimmer comes with a handy blower that produces an impressive 170 MPH.

The head can both rotate and angle to provide easier access to more obstacle-covered areas and yards with 1/2 –inch tall grass.

Additionally, there’s an edger attachment. The straight 8-inch blade cuts to an edging depth of 2.5 inches.

For the limitations, the machine is too short, which could be a challenge for tall users. It may also require more maintenance since it’s cheap.

Yet, all in all, the Southland SWSTM4317 wheeled string trimmer is a convenient alternative to handheld models. Its useful swivel head works well for detailing maintained yards.

3. Biggest Trimmer Line Size: Dirty Hand Tools 101085 Kohler XT675

Dirty Hand Tools 101085 Kohler XT675

The Dirty Hand Tools 101085 Kohler XT675 Engine Walk Behind High Wheel weed eater is an agile and powerful piece of lawn equipment that has the capacity to tackle the toughest of jobs in the most difficult locations.

This trimmer from Dirty Hand Tools provides a range of impressive features for a very competitive price.

First, it is armed with the standard 22-inch cutting swath. When paired with a trimmer line size of 0.157 inches in diameter, you can guarantee fast and clean trimming.

Unlike traditional handheld units, this model boasts 5 cutting heights from 1.5 inches to 3.5 inches that can take down waist-high weeds with minimal effort. Consequently, you can munch inside corners and edges, as well as against posts and fencing.

For instance, 3.5 inches may be low enough if you are battling an overgrown yard for the first time.

Meanwhile, you can go for the lower setting of 1.5 inches if the worse of the weeds are already under control.

What’s particularly interesting is that the Dirty Hand Tools 101085 has an EPA/CARB approved 3600 RPM engine with an automatic choke.

As a result, you gain reliable operation, easy starting, hassle-free trimming.

It is also reassuring that it can offer a respectable 149cc engine output. 

When combined with the easy-to-start automatic choke, you can get quiet operation for up to 50 minutes. Also, the 3-gallon fuel tank capacity can cover up to 3 acres of lawn.

Next, this wheeled weed eater has a unique trimmer ball design with dual 4-inch heat-treated blades. In this way, you can tackle woody foliage with ease.

Likewise, the 14-inch wheels deliver a perfect center of gravity. It enables you to function on uneven terrain with outstanding movement.

If low maintenance is an enticing factor for you, then you are looking at the right model. The patented trim ball resists string pull-out. Subsequently, it will keep the string secure, even in difficult conditions.

It’s worth mentioning that you have to buy optional accessories separately. You may purchase replacement string, replacement blades, and tree guard for added protection.

In addition, the Dirty Hand Tools 101085 Kohler XT675 High Wheel walk behind weed eater has a metal blade that supports the string. 

Due to this, you lessen wear and tear, while also providing extra cutting power for troublesome grass.

Another likable feature is the ability to disengage the trimmer while keeping the engine running. This permits you to pause if you need to safely clear debris from in front of the unit.

What our team disliked the most during our tests is the fixed cutting orientation because you can’t swivel the trim head to obtain a neater edge.

Hence, the Dirty Hand Tools 101085 may not be the best option if you have lots of flower beds or other obstacles to trim around. But this is worth considering if you’re looking for a keenly priced trimmer to clear a large yard.

Despite some flaws, it remains an easy-to-start model with adjustable height and string length. You can also rely on the high wheels for better mobility.

In conclusion, the Dirty Hand Tools 101085 Kohler XT675 Engine Walk Behind High Wheel String Trimmer is user-friendly while being tough on grass, weeds, and brush.

The engine makes this wheeled trimmer a piece of reliable equipment. The adjustable large wheels provide mobility around a rough lawn and a more consistent cut line when working on uneven terrain.

4. Longest Operating Time: Husqvarna HU625HWT High Wheel Trimmer

Husqvarna HU625HWT

Long-time gardeners are familiar with how Husqvarna cemented its name in the world of lawn care because of their sturdy and quality maintenance tools.

One example of their greatest inventions is the Husqvarna HU625HWT High Wheel Trimmer. This uses a 163 Briggs and Stratton engine to utilize its 22-inch cutting width.

This standard cutting swath provides a good balance between covering large areas quickly, while still being able to cover confined spaces.

Here’s a bit of trivia—did you know that Briggs and Stratton powers some of the most well-known gardening tools in the world? It’s your assurance that the engine is powerful and reliable.

Furthermore, it uses a string of 0.155 inches in diameter. If you invest in a good quality string, you’ll be able to keep going for ages without replacing it.

Thus, the Husqvarna HU625HWT walk behind string trimmer is perfect for areas up to 2 acres. It’s the ideal alternative for a handheld trimmer and mower.

In the case of hitting rebar markers or metal posts, you will not face any difficulty in replacing the trimmer line.

Another feature that our team adores is that the trim height adjusts from 1.6 to 3 inches.

This makes it convenient even if you have to spend up to 120 minutes in trimming. In relation, replacing the trimmer line only takes a few minutes.

With a 12-inch wheel size, you can guarantee durability and longevity. The wheels will surely roll smoothly over hilly and rough terrain.

There’s a 2-gallon fuel tank capacity, but the actual operating time would only consume a small amount of oil.

If this is your first time trying a string trimmer, you don’t have to worry about powering it up because despite having a large engine, you can start the unit on the first pull.

Furthermore, it only takes less than 30 minutes to assemble the Husqvarna HU625HWT WheelTrimmer. You can even disengage the trimmer and leave the motor running if you want to. We also noticed that the machine doesn’t overheat.

Remember, this wheeled weed whacker uses a pull cord start. However, the mow ball is made of thin plastic that wears out quickly.

On the flip side, be careful with the plastic plate that carries the string. The material is prone to usage, but with careful usage, it should last longer.

If you’re not contented, you can also buy replacement carrier plates, but they are not cheap.

Additionally, blades and other attachments are not compatible with the body. It’s all about trusting on the equipment’s cutting capacity.

The Husqvarna HU625HWT is not a substitute for a mover. Nevertheless, this model is a powerful and reliable trimmer.

You can count on it to effectively munch up grass fast. It could also trim around trees, shrubs, and flower beds.

To sum it up, the Husqvarna HU625HWT high wheel trimmer handles your tough trimming tasks while you enjoy the walk. With remarkable engine power, cutting swath, and trimmer line size, you can finish large trimming jobs in less time.

5. Most Powerful Engine: Poulan Pro PR22WT 675 EXI Walk Behind Weed Eater

Poulan Pro PR22WT

The Poulan Pro PR22WT 675 EXI Series Walk Behind String Trimmer has a cutting width of 22 inches. This enables you to complete large trimming jobs in less time.

This standard trimming swath has several advantages, First, there’s a ball guide that will not turn if it hits the ground. Secondly, the cutting width prevents wear despite contact to surfaces.

The fixed-line advance uses a standard 0.155-inch diameter trimmer line. With these features alone, you can cover a yard for up to 2 acres in under 120 minutes.

Reloading the strings is also pretty simple. It only took us about 2 minutes since the tool basically has guided lines on where and how to put the strings.

Because of the dependable Briggs & Stratton 625 Series 190cc engine, the tool is suitable for cutting both small bushes and tall grasses.

Similarly, the 4-gallon fuel tank capacity provides plenty of torque or up to 6.75 ft-lbs.

Hence, its durability lets you work near driveways, fences, posts, and more while still keeping the nylon line in tack.

The Poulan Pro PR22WT 675 EXI Series brags a choice of 6 easily-selected cutting heights. The lowest is at 1.6 inches while the highest is at 3.5 inches.

For convenience, there are easy rolling high rear wheels for added mobility freedom on hilly and rough terrain.

Its best asset is the innovative technology that doesn’t require oil changes.

It comes with a ‘Just Check and Add’ feature, which means you never have to worry about the hassle and mess of carrying out full oil changes. In this manner, you rarely have to check the oil level and top it up whenever necessary.

Another good thing is that this model starts easily. With a patented ReadyStart technology, there’s no need for choke or priming.

This wheeled weed whacker is simple to assemble. You’ll need only a few minutes to fix the handle in place and add gas and oil.

Sadly, the Poulan Pro PR22WT String Trimmer has no throttle. Consequently, you can’t lessen RPM levels.

Like most wheeled weed whackers, blades and attachments are not compatible.

If you want big wheels, you might not be satisfied with this unit’s 12 inches in diameter. On the bright side, the wheels are sturdy, which makes them highly capable of keeping the trimmer stable on uneven ground.

But here’s another redeeming feature – the Poulan Pro PR22WT comes with metal clips. Normally, trimmers use plastic clips for the strings, which can snap easily.

Based on our team’s experience, this model is highly recommendable if you are dealing with extremely high weeds since the machine doesn’t bog down.

Overall, with a 22-inch cutting swath and powerful engine, the Poulan Pro PR22WT 675 EXI series walk-behind string trimmer is a good option for bigger lawns.

The adjustable deck and speeds help with varying jobs. Also, convenient mobility works well on yards with rougher terrain and more varied layouts.

How We Selected And Rated The Best Models

We searched the market for various models that have justifiable power, consistency, mobility, durability, maintenance, and price.

We are going to be honest, each unit has drawbacks, but the models on this list have the upper hand.

It is important to see whether a Push weed eater can help if:

  • You want more power to face thick weeds and grass.
  • You need more maneuverability.
  • You require less frequent maintenance.
  • You desire a more long-lasting tool.
  • You have to go through tough trimming jobs.
  • You need power consistency for both light and heavy trimming jobs.

Fortunately, our selected products can comply with these requirements.

How To Choose The Best Wheeled Grass Trimmer?

Orange Wheeled Trimmer

There’s quite a number of features you have to consider before buying a model. It can be perplexing at times.

This is why we’ve developed this section to walk you through the necessary factors in choosing the right unit for you.

Yard Size

You can use a wheeled string trimmer on both small, medium, and large-sized yards. Typically, lawn owners would go for a handheld model if they have a small space.

While this is acceptable, you may opt for a walk-behind unit if you do not want the strain of carrying tools. This is especially true if you are covering a massive area with tall, overgrown grass.

The models we’ve introduced are more appropriate for large acres.

Weight And Dimensions

Push weed trimmers tend to be bulky because of the engine. But since there are wheels, you won’t face the dreadful task of carrying the tool on your back or using your hands.

This type of trimmer is beneficial if you need to avoid carrying heavy equipment.

Engine Power

The amount of power depends on the kind of job. This is why it’s crucial to identify the engine output first.

The engine output determines a unit’s ability to tackle trimming jobs. For example, you need more power if you will munch tough foliage like dense weeds, thick grass, saplings, and shrubs. 

Moreover, generous engine output is enough for lighter tasks such as maintaining thinner weeds and grass. Other options in the power trimmer category are gas-powered 4-cycle trimmers

To give a clearer picture, string trimmers are ideal for grass and weeds only. Therefore, do not expect that even a model with a 190cc engine can take down a young tree.

You also have to be mindful of the fuel tank capacity. The larger space you have, the bigger engine you need to trim quickly. Make sure you have enough fuel to finish the task in one round.

Cutting Swath

Cutting Swath

Since wheeled string trimmers are more ideal for large areas, you have to consider how long it will take for you to cover.

Additionally, trimmers have different cutting widths. Our list has 1 model with 17 inches while the rest have the standard 22 inches.

It’s advisable to go for a 22-inch cutting swath because it will get your yard cleared at a faster rate.

Trimmer Line Size And String Replacement

Always go for a thick string. The thickest string utilized in push grass trimmers is 0.155 inches in diameter.

Light duty

0.065 to 0.080 inches

Perfect for light weeding and trimming in small or standard residential yards.

Medium duty

0.085 to 0.015 inches

Ideal for commercial gardens or lawns that have dense grass.

Heavy duty

0.110 inches and above

Recommendable for acres of land or large properties.

At 0.105 inches, the Southland SWSTM4317 Wheeled String Trimmer has the thinnest string. This is because of its small size and engine.

Meanwhile, the Dirty Hand Tools 101085 Kohler XT675 walk-behind weed eater has the thickest line size at 0.157 inches.

Remember, the thicker the string, the longer its lifespan. A thick string is particularly advantageous if you have to deal with woody weeds.

Push string trimmers can handle tough shrubbery, but it’s still advisable to keep some replacement lines readily available.

Cutting Height

Another good feature to have is adjustable height settings. Even if a couple of units would have a similar cutting swath or trimmer line size, the output would be different if they have different cutting heights.

For example, if a lawn hasn’t been cleaned in months, the grass might be several inches high. But if it’s well-maintained, you will only face a couple of inches. This is where the adjustable height settings come in for your convenience.

Similarly, it’s advisable to go for a lower cut if you’re covering an area of scrubby growth. Meanwhile, you can reduce the cutting height in stages if you’re after a quality finish.

Know that most units will cut to a height of between about 1.5 and 4 inches. Normally, the equipment will begin at the pre-set increments. Therefore, you must check the user manual on how to adjust the height range.

Wheel Size

Wheel Size

The best thing about walk-behind weed trimmers is that there are varying wheel sizes.

Keep in mind that smaller wheels will require more effort to control. This is why you should opt for more than 14 inches in circumference for easier maneuverability.

A machine with larger wheels will be easier to redirect. As a result, you get to cover more areas faster. Also, it lessens resistance when you have to go up on hills or push over on the uneven ground.

The Southland SWSTM4317, Husqvarna HU625HWT, and Poulan Pro PR22WT have 12-inch wheels. Meanwhile, the Dirty Hand Tools 101085 and Remington RM1159 have 14-inch wheels.

Comfort And Ease Of Use

When it comes to lawn equipment, ergonomics is sometimes overlooked. What users tend to forget is that ergonomics impact the weight, maneuverability, and overall comfort of a tool.

For instance, a heavy unit is harder to control especially on rough terrain. A model that is easy to push around would make the trimming job easier and more comfortable.

Another thing, it’s likely you will be pushing the tool along uneven terrain, so be prepared to face bumpy ground and areas. Consequently, weeds and grass tend to be thick in such places.

Similarly, you would want a handle grip bar at the right angle and height to decrease strain on your back while pushing.

In addition, a trimmer is a vibrating tool, which can make your shoulders, hands, and arms feel tingly for quite some time. Some units have vibration dampening that will permit you to work on extending periods of time.

Thus, it is crucial that you can comfortably push the trimmer, so you won’t feel any strain on your arms or shoulders.

Noise And Pollution Levels

For lawn owners, the noise and emissions coming from a walk behind weed eater are normal. However, this might not be the case for your neighbors.

The tolerable noise range is between 60 to 90 decibels. Most fuel-powered models, like the ones on this list, have a decibel rating around that range.

You won’t be getting any problem in this aspect because we made sure that the products reviewed have passed this criterion.

Warranty And Price

1 Year Warranty Logo

Here’s another great deciding factor. Remember, you pay for the features that a model has. So the more innovative and powerful features a unit has, the higher the chance that it has a bigger price tag.

But this is not the case every time, sometimes there are affordable walk behind string trimmers that have the same assets with expensive ones.

Generally, the engine makes a unit pricey. But in terms of value, having a costly, yet powerful engine is definitely worth the investment.

In this post, the Poulan Pro PR22WT is the most high-priced, but it makes up for its features. Meanwhile, the Southland SWSTM4317 Wheeled String Trimmer is the most low-cost, but it has the smallest engine output.

Moreover, a unit’s material also determines the cost. A model that is mostly made out of steel or metal means good and long-lasting quality.

But this doesn’t mean that plastic-made tools are not well-made. There are some components that are better off using plastic. For instance, there are models that use plastic for safety shields and bumpers.

Likewise, the wider the string diameter, the tougher it will be and the less often you’ll have to replace it.

But this saves you money in the long run because there’s no need to regularly change the string. In contrast, a small string diameter may add up to the cost.

On the other hand, the warranty is your guarantee for reliability. However, most warranties only cover the tool. Some manufacturers have different warranties for other mechanical parts.

Rest assured that all units in this post have 2-year limited warranties.

Based on our analysis, higher-rated trimmers usually have a longer warranty since they are more reliable. On the contrary, lower-rated trimmers normally have shorter warranties.

When it comes to mechanical equipment, we believe that a pricey unit is worth buying if it guarantees durability. This would also enable you to save up on possible maintenance expenses.

But if you think that a low-price model outperforms an expensive unit in terms of specifications, then trust your guts.

Common Queries About Push Weed Trimmers

Why You Should Opt For A Wheeled Unit

Man Showing Wheeled Grass Trimmer

First things first, although a walk-behind weed eater can neatly trim your lawn, they aren’t specifically designed for a manicured finish, unlike mowers.

Although the trimmers we’ve introduced have their own unique mechanisms that make perfectly curated cuttings.

If you’re cool with this, then you are definitely in for a treat. As you’ve seen in our product review, this type of unit provides more power. Even the compact unit will give 35% more torque than handheld models.

In addition, you’ll only have to push the equipment around. Handheld units, which are also designed to lessen strain, can still cause fatigue during long hours of usage. Your muscles will certainly choose the wheels any day.

How To Change The Trimmer Line?

You can find the spool of trimmer line in the head. In there, the line would do the cutting by spinning.

Due to constant use, the line could wear down or eventually break. When this happens, you need to feed out more lines from the spool.

If this is your first time using string trimmers, know that it could sometimes be hard to load the tool. This is because there are various string lengths.

Before you start tinkering on your tool, make sure to check the user’s manual for guided steps on how to replace the string. Some models have specific ways, but here are general steps you could follow:

  1. Turn the engine off. 
  2. Check whether grass, mud, or debris are clogging the area between the shield and the hub.
  3. Discharge the hub from the motor shaft. Some units have tabs you can push or pull to unlock the hub from the shaft.
  4. Remove the trimmer line spool from the hub.
  5. Discard any remaining trimmer line on the spool.
  6. Place the new trimmer through one of the holes in the center of the spool.
  7. Tightly wind about 15 to 20 feet of the new line onto the spool.
  8. Lock the trimmer line’s end into the notch along the outer edge of the spool.
  9. Cut the line and leave approximately 6 to 8 inches of the line free.
  10. Insert the spool into the hub.
  11. Guide the free length of the line through the hole in the hub.
  12. Secure the spool into place.
  13. Resettle the hub onto the motor shaft.

Safety Precautions

Using Gloves

We always remind our readers that using mechanical equipment comes with safety risks. All you have to do is be aware of safety precautions and then you’re good to go.

  • Make sure your fingers and toes are covered. Trimmers can cut everything within its range. Therefore, it’s advisable to wear gloves and work boots.
  • Do not use a trimmer when you are wearing hanging jewelry or loose-fitting clothes.
  • Since you are using an engine, it’s possible to have higher noise levels. To prevent hearing loss, it’s advisable to wear ear protection.
  • The tool can fling debris at high speed. Thus, you should wear protective eyewear or goggles. If it’s possible, you can also wear a mask.
  • To prevent flying debris, do not operate the machine over stone, sticks, woodchips, or gravel. Clear the ground first of any debris.
  • Always mind a safe distance between your body and the motor. The engine can get hot when turned on for a long time. Although some units now have features to prevent themselves from overheating, it’s still wise to be mindful of the gap.
  • Keep children and pets away from your working area.

How To Properly Store The Machine

The key to making a unit last longer than expected is through proper storage. Some units have rust-resistant coatings, but this doesn’t make them totally weather-proof.

This is why you should check the dimensions of a unit first. In this way, you’ll have an idea of how much space it will take from your garage or shed.

Models with a 17-inch cutting swath tend to be smaller whereas 22-inch would require a bigger space.

Furthermore, if your push grass trimmer has foldable handles, then you can save up on space.

Make sure to turn off the engine and let it cool before storage.

Cleaning And Maintenance

This is another factor that can lengthen the lifespan of your equipment.

  • Once the motor is turned off, remove stuck leaves or debris using a small brush.
  • Check for wear and tear to see if the string is down to half its original length.
  • Replace the string whenever necessary. Only use the recommended thickness by the manufacturer.
  • Only use approved replacement parts for damaged accessories.
  • Check the oil level regularly.
  • Keep the engine lubricated.
  • Spray light oil on all metal surfaces to prevent rust.
  • Drain the gas tank before long-term storage. 

What Is The Right Option?

And that’s a wrap! We’ve shared all our information about choosing the best walk behind weed trimmers.

Finding the right model could be confusing and challenging. But with the right details, you will surely be able to pick one.

We hope our comparison chart, buying guide, product review, and FAQ section have helped you make a wise choice.

Moreover, the units we’ve revealed have superior features and strengths, despite having a couple of weaknesses.

But to remind you, the Remington RM1159 Walk-Behind High-Wheeled String Trimmer is our top pick when it comes to overall quality and features.

The Husqvarna HU625HWT High Wheel Trimmer and Poulan Pro PR22WT Walk Behind String Trimmer are our runners-up.

Meanwhile, the Southland SWSTM4317 Wheeled String Trimmer and Dirty Hand Tools 101085 Walk Behind High Wheel String Trimmer are good choices if you want to save some bucks.

Keep in mind that while features such as cutting capacity and engine power are crucial, you should still consider your own comfort and preferences.
