Frequently Asked Questions (FAQs)

1. Are trimmer spools universal?

Final Thoughts. To sum it all up, there might not be a universal standard for string trimmer heads. But, if you work with gas powered trimmers, it shouldn't matter all that much. As long as your arbor bolt and upgrades are compatible, you ought to be good to go.

2. What string trimmer string Do professionals use?

Oregon 22-595 Gatorline Heavy-Duty Professional The thick . 095 diameter line is a good size for heavy weeds, thick grass, and brush in a variety of settings, including residential and commercial properties.

3. How long does a trimmer spool last?

You should replace trimmer string spools once every 90 to 180 days if you use the trimmer weekly. Overusing the trimmer string greatly increases the chance of it breaking while you're using it. If you don't replace it often enough, the ends will fray, and it won't chop through the weeds.
