Frequently Asked Questions (FAQs)

1. Is it better to have thicker or thinner trimmer line?

The thickness of the trimmer line depends on the type of work you are doing. For light tasks like trimming grass, a line in the 0.065″-0.085″ range should be sufficient. Thicker grass and weeds require a line in the 0.085″-0.110″ range. Anything thicker than 0.110″ is suitable for thicker underbrush. Keep in mind that using thicker lines may affect power and runtime, especially with cordless string trimmers.

2. How do you cut overgrown thick weeds?

To cut overgrown thick weeds, it is recommended to use a rotary mower or brush hog to cut the plants before turning the soil. It is advisable to avoid turning the soil when dealing with aggressive weeds like Thistle, Cocklebur, Bermudagrass, or Johnsongrass, as disturbing the soil can cause them to spread more aggressively. Mowing down the weeds with a rotary mower is an effective way to manage overgrown thick weeds.

3. Are all trimmer spools interchangeable?

Most trimmer spools are interchangeable, allowing you to use non-OEM (original equipment manufacturers) line. However, it is important to note that larger or heavier lines may not fit every string trimmer. It is recommended to replace the old trimmer line every spring for optimal performance.

4. Are all trimmer spools the same?

No, not all trimmer spools are the same. Different trimmers have specific line size or style requirements. Most household-level trimmers can accommodate line sizes up to 0.085” in diameter. However, more expensive or larger models may support lines up to .155”. It is important to check the specifications of your trimmer to ensure compatibility with the appropriate trimmer line.
