12 best rotary lawn trimmers

Rotary lawn trimmers, commonly known as string trimmers or weed eaters, are versatile outdoor power tools used for cutting grass and weeds in areas that a lawnmower cannot reach effectively. These tools consist of a small engine that powers a rapidly rotating string or line, which cuts through vegetation with a spinning motion. Here are some key aspects related to lines, spools, and replacement parts for string trimmers:

  1. Lines and Spools:

    • The cutting element in a rotary lawn trimmer is typically a nylon line or string, which comes in spools.
    • Lines wear out over time, and spools are designed for easy replacement to maintain optimal cutting performance.
    • Various thicknesses and materials of lines are available to suit different trimming needs.
  2. String Trimmer Parts and Accessories:

    • String trimmers have several parts that may require replacement or upgrading, such as air filters, spark plugs, and carburetors.
    • Accessories like blade attachments, guards, and harnesses enhance the functionality and safety of the trimmer.
  3. Replacement Parts and Accessories:

    • It's important to use manufacturer-recommended replacement parts to ensure compatibility and performance.
    • Replacement parts may include spools, trimmer lines, cutting blades, and other components that might wear out over time.
  4. Outdoor Power Tools:

    • String trimmers are part of the broader category of outdoor power tools, which also includes lawnmowers, chainsaws, hedge trimmers, and more.
    • These tools are designed to make lawn maintenance tasks more efficient and manageable.
  5. Patio, Lawn, and Garden:

    • String trimmers are essential tools for maintaining a well-groomed lawn and garden.
    • They help in reaching tight spaces, edges, and areas where a lawnmower may be impractical.

When using rotary lawn trimmers, it's crucial to follow safety guidelines, wear appropriate protective gear, and adhere to proper usage instructions provided by the manufacturer. Regular maintenance, including the replacement of worn-out parts, ensures the longevity and effectiveness of the tool in keeping your lawn well-maintained.

User questions & answers

Question: Will this line work with .080 push thru style line heads..2 lines that u push a button and line gets inserted and release button to hold line in head
Answer: If your head will accept a .080 line this will work
Question: Package pictured seems awful small for 320'. What is the length of line in this package
Answer: I cannot verify the length of line in this package, but I can verify that I received the length of line identified with my order. The package is about 6-7 across and appears to be the same container as I received.
Question: If not using an auto head, cutting this in 7 1/2” lengths, will the cut pieces tend to curl after cutting or does the line stay straight
Answer: Dont know bout 7.5" in lengths but sure would try this stuff as its the best thing since sliced bread for trimmer line. I couldnt believe the difference. I live near water n saw grass was nearly impossible to cut with standard poly line but this stuff goes thru it with ease. I would spend a few bucks on a 25 ft roll n try it.
Question: could I use the 0.080 line on a Black and Decker trimmer designed for 0.065 since Vortex does not make it in
Answer: I think it would work. The Vortex line is very flexible, but very strong. The diameter shouldn't cause an issue with the slots on your trimmer. It's the best line I've ever used over the 30 years I've been using weed-eaters.

User questions & answers

Question: Can you buy this stuff in .080" diameter
Answer: I think yes only yo u see what size have in stock the store
Question: I currently use a .090 line in a Stihl trimmer. Can the Vortex .095 fit my trimmer
Answer: Yes I believe so . That's a very small difference in thickness .. I use the vortex line in the still rs 75 trimmer
Question: Can i use this on a toro battery 40v 13" (33.02 cm) string trimmer/edger (51481) it says it uses a 0.08" (2.03 mm) thick single line with auto feed
Answer: No, this line is .095 inches thick, I think it's too big.
Question: Are the rating real, is this line decent,I just can't find something that lasts a while
Answer: I've been using this for 2 years after watching the video talked about in other reviews. I ran through a giant $25 spool of HD stuff in one summer. It was about half the length of this spool. I was re-spooling it every two weeks. I use my trimmer 30 times a year. I still haven't replaced the first spool of this stuff that I put on my trimmer. I typically have to extend the string one to two times per lawn cut. I only have the stock Stihl trimmer string, and the HD stuff, that looked promising, and this item to compare. This items wins hands down.

Question: If you have a Stihl trimmer that calls for .065 trim line, will this work in it? If so, why does Stihl call for a so much smaller diameter line
