Common Features of Wheeled String Trimmers


Wheeled string trimmers are all powered by the same kind of engines – 4 stroke ones that need oil changes as well some other maintenance to keep working properly. Most wheeled string trimmers’ engines also come with recoil starters that have to be pulled by a starter rope that turns the engine over and gets it going.

Rugged Capability

There are multiple reasons as to why wheeled string trimmers are a great choice for thick brush and rough terrain – they are large (12 to 16 inches), which enables them to be more easily maneuverable on uneven ground. Since the wheels are composed of hard plastic or a Never Flat material, there’s virtually no chance of a flat tire. The cutting width of walk behind string trimmers is a hefty 22 inches, so a lot of ground can be covered at once.

Replacement Line

Since wheeled string trimmers are able to handle tough brush, their line breaks more often as you work through the shrubbery. It’s a good idea to pack some replacement line; it can come in several different lengths and diameters as per your trimmer and job requirement.

Walk Behind Trimmer Buyers Guide

Buy a wheeled string trimmer that is strong enough to handle the weed growing in your backyard – remember, skimping on the cash will eventually lead to a lot of frustration, besides the money being a total waste. You’ve got plenty of options to choose from, make sure to pick the one that suits your particular needs.

Yard Size

First and foremost, you need to take the size of your yard into account, as well as the kind of terrain you’ve got. Based upon this, you can decide on whether you need to buy a high powered walk behind string trimmer, or a lighter model that you’ll only use for tackling the occasional weed growth in your yard. Remember, skimping on the cash will eventually lead to a lot of frustration, besides the money being a total waste. You’ve got plenty of options to choose from, make sure to pick the one that suits your particular needs.

Think Storage

If you have a storage problem, go for a walk behind trimmer that comes with a fold down handle so you can easily tuck it away in your garage under other stuff.

Comfort and Ergonomics

Install an ergonomic harness on your walk behind weed trimmer to make it more efficient, comfortable and easier to use. The handlebar of the string trimmer must be angled against the shaft to prevent it from putting unnecessary strain on your back as you work in the field. Make sure that the model you choose has sturdy vibration dampening characteristics.

A vibrating tool can make your hands, arms and shoulders feel tingly and uncomfortable for quite some time after you’ve stopped working, but if your wheeled weed eater has vibration dampening, you can work on it for longer periods of time without experiencing this side effect.

An easy to use walk behind trimmer that gets the job done, even when you’re facing some seriously tall and tough weed growth.

Husqvarna HU625HWT 190cc High Wheel Trimmer

Quick Info

  • Warranty: 2 years
  • Cutting diameter: 22’’
  • Engine size: 190cc
  • Line Size: .155″
  • Price: $$$

Our Rating:

4.1 Stars

The Husqvarna HU625HWT high wheel walk behind trimmer is formidable, thanks to its hefty 190cc Briggs & Stratton engine that can work its way through tough, unyielding weed and grass that standard weed whackers can’t handle. It also comes with adjustable height from 1.3 to 3 inches, and it is super easy to replace its cutting line. We did find some evidence of subpar build materials though. Note that it isn’t compliant with the CARB, so it isn’t for sale in California.


  • Easy to start up and operate.
  • Works great with tough weed and grass.
  • Doesn’t consume a lot of oil.
  • Easy to replace cutting line.


  • The string carrier can get damaged easily because of its weak build.
  • Possible design flaw may cause weeds to stick around the shaft that can lead to more damage.

Swisher ST67522BS Standard String Trimmer

Quick Info

  • Warranty: 2 years
  • Cutting diameter: 22’’
  • Engine size: 190cc
  • Line Size: .155″
  • Price: $$$

Our Rating:

The Swisher 6.75 gross torque weed trimmer packs all the standard features you would expect from a product in its price range – a sturdy engine, 14 inch wheel diameter, and a 22 inch cutting swath. It also claims to have superior ergonomic design to alleviate the back ache associated with certain other competitors.

However, this appears to be true only for users fitting a specific physique and build. Having said that, this string trimmer does get the job done remarkably well thanks to its hefty 190cc engine and tough cutting line, even though its components’ build materials leave something to be desired.


  • Strong engine and tough cutting line cut easily through tough weed.


  • The 14’’ wheels can be hard to push.
  • Not as quality of building materials as others.

Fields Edge M220 Walk Behind String Mower

Quick Info

  • Warranty: 5 year Limited
  • Cutting diameter: 22’’
  • Engine size: 173cc
  • Line Size: .155″
  • Price: $$$$

Our Rating:

The Fields Edge M220 is all about versatility – its wheel pivot system makes it an excellent all-purpose trimmer. In fact, it is one of the few that have this feature which lets the user offset the head position during operation – this places the head in the perfect spot for trimming along walls and fence lines.

As far as the cutting goes – the M220 uses a Hard-Core high density cutting line that is a lot more durable than the competition, thanks in part to the attachment system of the Clear-cut head. Changing the line is remarkably easy too. Since the M220’s Clear-cut head has the cutting line at two different levels, it blows the cut grass / weeds away rapidly, so that more vegetation can be cut with each revolution of the head.

The M220 comes with a strong 173cc 4 cycle engine, 14’’ diameter wheels, variable height from 1.5’’ to 4’’, and an adjustable cam-lock handlebar that allows it to be compactly stored.


  • The wheel pivot system allows for both mowing and trimming.
  • The cutting line is tougher than what we usually see in the competition.
  • Cutting line is easy to replace.


  • Relatively pricey.


To conclude, we’d like to put forth the Field’s Edge M220 as our best pick from the lot – and our choice largely comes down to two things – reliability and diversity. Even though the M220 costs a bit more than the rest, it is the only quality walk behind string trimmer that can be used to trim along fences, in addition to the standard grass/weed trimming functionality.

On top of that, its cutting line managed to impress us with its durability; this is a huge plus where the most frequent complaint about the others is that their cutting line breaks during operation.

Remember, paying a little extra initially to get a quality product will save you from a lot of headache and maintenance costs in the long run.

    Very good reviews. I will do research to find out if the Field Edge M220 can be seen at a dealer instead of ordering
    on line without hands.
    I am surprised there was no review on any of the Dr. Equip. string mowers. I live on a 20 foot lope on my property.
    Not sure if I would want to “hand push” the mower. Dr. does offer a self propelled but very pricy.

    Thank you Mr. Moore for all your research. I like the idea of not having to sharpen a blade. I do have a commercial Echo weed trimmer home residential use. But wow my arms and hands “vibrate” for a long time after use, but it does a good job. It also was interesting about you pointing out the “non-vibration” mower trimmers that are offered.
    Thanks again Rick

    I’m trying to find an electric start high-wheel field trimmer. My rotator cuffs are shot and I can no longer pull start the Southland trimmer I have now.
    Do you have any recommendations?


    • Joan Hulsey says:

      I don’t know why he didn’t mention the Dr Trimmer. I have one and love it (I’m a woman in my 60’s and not particularly strong). It does have an electric start and is self propelled. I have an extremely large yard and lots of weedy areas, this cleans them like a champ!
