    • Much tougher than I expecred.
Size: 3 lbs
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. ... show more

    • Very tough, made for the rough jobs
Size: 1/2 lb
We use a walk behind string trimmer that's very powerful. This is not a spool unit, you cut lengths of trim wire and feed it into holders. This stuff is very strong, I cut through tall grass, thick weeds, and even tree seedlings up to about an inch. Great stuff.

    • EXTREMELY DURABLE AND EFFICIENT.... FINISH IN HALF THE TIME!!
Size: 5 lbs
This line is very durable for heavy grass and weeds. Lasts longer than OEM trimmer line. The square shape takes more horsepower to rotate but cuts quicker and easier making up for slightly reduced RPMs. This line 'slices' through weeds and grass whereas round line tends to beat the grass and weeds. In addition this line moves the cut grass to the side and out of the way better than round line. Works well on tougher grasses that are more difficult to cut. 8/19/2019 addition In the fall we have a very tough grass (crowfoots grass and broadleaf signal grass). Both extremely difficult to cut... DR'S ROUND GREEN LINE JUST BEATS IT DOWN. This line actually cuts the grass... EASILY I MUST SAY... AND MOVES IT TO THE SIDE TO CONTINUE CUTTING. I DON'T CARE HOW OTHERS RATE THIS TRIMMER LINE BUT IF YOU WANT THE BEST... IT IS A LITTLE DIFFICULT TO INSERT IN THE DR head BUT ROUNDING THE ENDS MAKES THIS TASK MUCH EASIER. IT ALSO LASTS AND LASTS... DON'T THINK I'LL EVER SWITCH!! ... show more

    • Holds up better than the line that came with the machine.
Size: 3 lbs
Holds up much better than line that came with machine. The last three lines I installed have lasted for over one tank of gas. It will cut through fibrous stalks of 1/4 inch to 1/2 inch and woody stalks of up to 1/4 inch. Anything larger, or any rocks, and it will break fairly quickly. The one advantage of the stuff that came with the machine was that its orange color made it easy to find after it broke versus this line which is clear to slightly gray. Will buy again, but hopefully won't need to for another year or two. ... show more

    • Good, long lasting stuff!
Size: 3 lbs
Very durable. This is a premium product, and has outlasted every other line that I have tried. I installed this line on a 6.5 hp high wheel trimmer, and I can now trim for over 30 minutes without stopping to replace the line. I was getting about 10 minutes of line life from another premium brand of line on the same machine. This takes out any grass, and smaller diameter woody plant life with ease. Be careful if using around a lightweight wood fence, as this line will nibble on soft wood fences or remove paint from your fence. The only things that cause much wear to this line are steel posts and concrete. It is a good idea to store any unused line away from sunlight, as UV light will weaken the plastic and result in shorter line life. ... show more

    • Super Heavy Duty Line!!
Size: 1/2 lb
If this line can fit in your trimmer head, and you need some heavy duty line. This 100% works!! I have a commercial duty Stihl trimmer with an Echo Speed Feed head. I had to modify the inner hub of the head to accept this thicker line by drilling out the hole to a larger diameter. This line is so strong my safety guard line trimmer has a hard time cutting it after feeding. I live in the country, not a huge property but have a riverbank, lots of wire fence line and plenty of oak trees.. this is the first time since I bought this property in 5 years that I trimmed the entire property in just one session. Mowed down heavy weeds and saplings with ease. Only had to bump the speed feed twice all morning! Super Heavy Duty Line!! ... show more
