Oregon22-855 Heavy-Duty Professional Magnum Gatorline Square String Trimmer Line .155-Inch Diameter 3-Pound Spool, Grey, 246 ft

I have a walk behind 6HP string mower that uses .155 line. I bought a roll of triangle yellow Ugly nylon style line from Sears 14 years ago when I got and that 100 ft. roll lasted a long time, but breakage and slip out was always a problem. It was soft, easy ro bend, and didn't really seat securely under the head clips. I thought this was just normal. I finally ran out. But after getting this Oreon Magnum line, my whole thought about .155 line changed. This is much much stiffer, thicker, a true square cut, and unless you hit actual small trees, does not break or pull out every 5 minutes. I beat the bonkers out of this stuff. If you hit small trees, it takes a beating but will break, but with protest It has a core you can clearly see. I am very amazed about how well this .155 line works. Some people mention getting .170 line for walk behind weeders. I imagine it would work real well if you could get it to insert by using a torch to soften the bend, but this .155 line fits quite tightly and securely. Not sure if .170 would pull into the head hooks. This .155 takes a pretty stiff pull and bend and to seat. Regarding using .170, you do need to have a limit on how much stress you put on the mower head. The replacement for a DR style trimmer head is close to $100. Secondly, the current price for this .155 for the amount you get is unbeatable. This roll is very big and will last till you die! It's a great buy currently. Not sure if the Platnum is as good from reading the reviews. But this stuff is impressive and still safe.

This trimmer line is very soft and breaks off within seconds of use, I am now using 3mm mono line and it lasts much longer

Heavy duty, thick line. I use it for a walk behind string trimmer. It's able to cut brush and small trees coming up easily. No issues with losing line when hitting objects; other than fencing. It holds up better when accidentally hitting fencing than most, but will get flung out if the line has been used for a while.

I use a Husqvarna brush clearing saw with this string. Good life but I prefer .177 dia
