## Questions & Answers

**Q: what is the difference between this 21-855 and 22-855?**
A: The 21-855 is our standard square, .155 Green Gator Line. The 22-855 is our professional dual polymer, square, .155 Magnum Gator Line.

**Q: Will the precut line work for a Stihl fixed head on a handheld  trimmer? I am currently using .95 and cutting pieces to insert.**
A: Thank you for contacting Oregon. We have no data to indicate if our .155 line, Oregon 19003 will fit in the Stihl DuroCut fixed line heads. What we can tell you is that the Oregon 19-003 will fit in the Oregon 55-403 Jet-Fit, Oregon 55-406-0 Kwik Loader & Oregon 55-191 Fixed Line head. Please contact Oregon Technical Services direct at 1-800-223-5168 option #1 if you have further questions.

**Q: Will this work on a cub cadet push weed trimmer**
A: Yes, I have a cub cadet push trimmer. Make sure you have one of the original "strings " so you can use it to measure the Gatorline. I love this stuff, works great !

**Q: If the square shaped trimmer line like this one is made to cut thick weeds then why is the shortest regular grass colored in green on the picture?**
A: This is the one my husband wanted.  This cuts thick weeds.  It will not fit all trimmers.   I have just reordered this item.

    Best .155" Line for Brush!
  

*by B***T on Reviewed in the United States on May 13, 2020*

This is absolutely the best trimmer line for a .155" trimmer I've found, as, in high/thick weeds:* the original round line just breaks almost immediately* the Rino Tuff yellow triangular line doesn't cleanly cut all the 3/4" weed stalks and ends up wrapping them around the axle, requiring a lot of effort to get them untangled and start mowing again* The Gatorline square green line cuts right through heavy weedsAlthough at this point, tall weeds will completely cover the machine, stopping forward progress. And backing up just re-chops the fallen stalks, breaking the line before long.This line is much thicker than the triangular Rino Tuff line and lasts far longer than the .155" Club Cadet line (which feels like half it's diameter).Any larger and it wouldn't be able to thread, yet the large size is a benefit, and the square edges make it easier:1. thread one end a short distance through the eye2. twist the square line at the other end so that the loop points downward (toward the hook opening)3. jamb it up against the other end that is already threaded and it slips right through4. grab both ends and pull togetherIt lasts longest if you cut just the base of the weeds and keep moving - even this line cannot handle re-chopping all the debris and that's when it breaks (after re-chopping long stalks a few times). It can break every 10 min. in heavy weeds with thick stalks. But in tall grass and softer weeds, it will last over a half hour and cut a half acre without breaking.It can still get tangled up, at least using the Club Cadet 22", which seems powerful, but possibly needs a higher RPM to cut thicker weeks of 0.5-1.0". The photo shows what can happen when the weeds are too thick and you can't keep moving forward. (This rarely happens with the Gatorline .155", but happens every few seconds with the  Rino Tuff.)But if you want to re-chop the fallen weeks, this is still the best line I've tried for clearing a few acres.

    Great value
  

*by F***R on Reviewed in the United States on October 13, 2013*

I have to be honest and say that I work my high-wheeled string trimmer very hard - mowing a couple of acres of field that sometimes runs me up against some brushy plants and vines that break the strings and sometimes the trimmer head itself.  I buy trimmer line in bulk and have tried several varieties, but always "twisted" varieties, which all have about the same breaking strength and durability. This string is square, which seems to be more durable. I'll speculate that it's more durable because the square shape provides more of a cutting edge that works better on my field vegetation than the more rounded edges of the twisted varieties. For grass, pretty much any type seems to perform well. So, I have to say, relatively speaking, that "I love it", and the price was good, too.  I still await the unbreakable trimmer line. Though I expect one can be manufactured that is unbreakable, it would be the quick route to driving one's self out of business!

    Oregon Gatorline
  

*by S***G on Reviewed in the United States on September 15, 2021*

I have tried several different brands of .155 string for my high-wheel weed eater. This square green Oregon line is by far the toughest I've found. It holds up much better than any of the others. Of course none of them will hold up to a wire fence but the Oregon will tackle tiny mesquites & other woody weeds & survive better than any of the others I've used.........
