Can I Use A Weed Whacker To Mow The Lawn

Can I Use A Weed Whacker To Mow The Lawn?

Mowing your lawn, albeit a little time consuming, is a very necessary process when it comes to the upkeep of owning a home, especially a home that has appropriate outdoor space. 

But sometimes there are situations where we don’t really have a lawnmower at the ready, or we can’t run to the store to purchase one just yet. 

Have a weed whacker lying around? This should do the trick. 

Yes, you can mow your lawn using a weed wacker. It’s doable. In fact, there are some areas that your lawnmower might not be able to reach, but your weed wacker can.

Here’s all you need to know before doing just that. 

What exactly is a weed whacker, anyway? 

A string trimmer, edge trimmer, line trimmer, grass cutter, weed eater, even weed whipper… you’ve probably heard it all before. Different places call it different things, but essentially they are all the same. 

The names are easily interchanged because there are actually brands names WeedEater and Weed Wacker. 

These are lightweight and versatile outdoor tools, and they are much lighter than lawnmowers. These are usually used to cut grass and weeds. It was even deemed one of the must-have tools for gardening and lawn maintenance. 

There are a variety of different kinds — battery-operated, gasoline-operated, and electric variations. More powerful trimmers usually operate on gas or engines that use a mixture of gas and oil. 

The string trimmer doesn’t use blades like a lawnmower does, which is also why it’s more lightweight. Instead, it uses a special kind of string made from mono/microfilaments or nylon line that is tough enough to help with trimming grass and weeds. 

This string usually uses centrifugal force, meaning a spinning motion, to cut the grass and weeds. They are perfectly complementary to lawn mowers for some, as they are able to reach spaces that lawnmowers normally wouldn’t be able to, because of their more compact size.

Lawnmowers typically can’t really trim more narrow pathways and sidewalks, driveways and fences or trees, shrubs, and flower beds. This is where weed whackers usually come in. 

Not only are they used to eliminate weeds from your lawn, but they are also perfect for getting into these areas, like grass that sprouts up from cracks or breaks in the sidewalk pavement, and also for terraneous areas.

Since string trimmers are smaller tools, do they cost less? 

Yes. Most string trimmer models are more affordable than a whole lawnmower, especially models that still have cords to operate. 

Some models are even more durable and need less maintenance than lawn mowers in general. 

These are definitely more affordable than cordless models, but you are limited to the space that your cord and extension cords can reach. 

Cordless models, on the other hand, do offer more convenience but will only work depending on how long their battery life is. 

Gas trimmers are the most powerful option since they are bigger and provide more convenience because refilling gas is the easiest option. But they do emit fumes and make more noise than the usual string trimmers. 

They also are a little harder to control than the other types of models, as well as being heavier. This is important to keep in mind when choosing which one to go with. 

Is it possible to work with a string trimmer instead of a lawnmower? 

It is! In fact, some people decide to invest in string trimmers instead of lawn mowers for a couple of reasons. But there are definitely as many cons as there are pros to doing that. 

The Pros and Cons of cutting grass with a string trimmer and some tips:

Yes, it is definitely possible to trim your grass with a string trimmer! It also saves you time, energy, and money in some cases. 

This is mostly dependent on the size of the area you are aiming to trim. Those with smaller grassy areas on their property might find string trimmers more convenient in many aspects: the portability, the price, and even the storage. 

But there are always pros and cons to using these devices, and they may be important to keep in mind before making the decision of which to invest in, or which to use.

  • Lawnmowers are already designed to make grass cutting so much easier, as they come with things like levelers and adjustments to cater to your needs. 
  • Sometimes grass only needs to be trimmed an inch or two, which lawnmowers have adjustments to do, string trimmers do not. 
  • Typically, only a third of the grass blade should be cut at a time. Anything more than that is not healthy for the grass.
  • Trimmers usually immediately cut down grass that is high, which could be a problem for the overall growth and health of the grass.
  • This is because of the shock it causes to the roots, which is done pretty regularly could permanently damage your grass.
  • When this is done to edges, usually the trimmers uproot or cut down to the root of the grass blades, which is why and how weeds end up on a lawn that’s otherwise healthy.
  • There are no more grassroots to stop the weeds from growing in these areas.
  • Since lawn mowers do use blades, the cuts on the grass are more sharp, precise, and even. String trimmers use string, but with a speed and force that tears the grass and causes damage that takes a pretty long time to heal. 
  • String trimmers can fling objects and debris that are in its way, not exponentially far but enough to maybe cause damage. 
  • It is important to make sure that there are no branches, sticks, pebbles, and other objects lying around. Also be aware of other wildlife lurking in the area, such as frogs. 
  • This would be fine, but it could be more time consuming to do in rockier areas. 
  • Trimmers are so much easier and quicker to use during the drier seasons of the year, as dirt in general tends to collect and dull the lawnmower blades for the most part. 
  • Dust may also clog the filters you would find on lawnmowers.
  • Because of possible debris, remember to wear protective-enough clothing and maybe even eyewear. 


It is definitely possible to use a string trimmer on your lawn, but weigh in on factors like the size of your lawn and the areas you’re going to be using it on. 

Also be sure to use protective devices like protective eyewear, footwear, and clothing that covers most of your skin.
