Our rating: 8 / 10

MILWAUKEE ELEC TOOL 2725-21HD 18V M18 STRING TRIMMER

Check Price on Amazon

Pros:

  • Powerful enough to tackle heavy-duty trimming
  • Ergonomic and lightweight
  • Great value for the price

Cons:

  • Takes a long time to charge up
  • Plastic blades can break easily
  • Not as easy to maneuver as a gas trimmer

This trimmer from Milwaukee is a lightweight, cordless electric model that comes in at just 6.3 pounds. It has a run time of up to 80 minutes after it has been charged for a mere 30 minutes, which is longer than full-size gasoline models.

It has eight different height settings, so you can get the kind of cut you need even when the grass is growing out of control. One of the coolest features of this trimmer is its tool-less design. Due to this, switching out guard parts is a lot easier and faster than with more traditional models.

One of the small issues with this trimmer is that it takes a long time to charge up, which can be somewhat inconvenient. This trimmer has plastic blades instead of metal ones, so it doesn’t stand up to heavy-duty trimming tasks. It also doesn’t have the same degree of maneuverability as a gas-powered model. Overall, though, the Milwaukee power tool offers a great value for the price.

String trimmers have become a necessity in the garden, thanks to their ability to make quick work of overgrown turf and vegetation. While most people use their electric trimmers for these jobs, the cord can often limit the area of your yard you can access, and they can take several hours before they cool down.

Now, there are cordless string trimmers available on the market; however, they might not be powerful enough to tackle your toughest yard care tasks. For that reason, you might be looking at a do-it-yourself job and want to make sure you have the best string trimmer line for each of those tasks.

Frequently Asked Questions (FAQ)

What string trimmer do professionals use?

The professionals use some cordless models. There are also electric ones. They can either buy them alone or can be ordered with some other equipment such as a blower which comes with some brands.

What is the best commercial string trimmer?

Well, that all depends on the size of your lawn of course. (If you have a huge area, then buy the commercial trimmer. If you have a small lawn, then go with the homeowner's trimmer.) And of course it also depends on your budget. (Remember: a cheaper trimmer is likely better for small lawns.)

To put it simply: commercial trimmers are heavier duty than homeowner's trimmers. This is the best trimmer on the market for grass that is two feet tall or longer and for people that have lots of lawn.

Which is the best gas string trimmer?

The best gas string trimmer is one that is balanced, lightweight, and fits well with your height. Features are also important, such as easy start and self-propelled functionality. If you plan to do a lot of trimming on your property, you will need to choose a string trimmer that offers extended running time.
