Magnum Gatorline Trimmer Line is ideal for professionals who need long-lasting, powerful tools to get the job done right. It quickly and easily cuts through low grass and grass-like weeds yet is durable enough to tackle sizable brush without breaking. This trimmer line is less likely to bond together in the trimmer head due to its weld-resistant outer layer. .170" diameter trimmer line is an ideal size for cutting tough brush. Magnum Gatorline is compatible with most trimmer head systems including fixed-line, semi and automatic bump-feed heads. Additionally, it fits most gas, electric and battery-powered curved and straight shaft string trimmers. Check your string trimmer manual for recommendations and to ensure that larger lines will work with your trimmer. This trimmer line is packaged in a user-friendly donut which prevents tangles.

Square line wears down faster on rock, just fyi.Otherwise tough as nails. Hard to get into a stock DR trimmer/mower head

I use this on my walk behind DR Weed wacker. It worked well, very strong. The down side is I have a DR weed wacker with the auto load head and because the line is square it gets stuck in the head and I had to take the head apart. So be careful I would say use the .175 .blue line

I used this on my walk-behind trimmer and it worked great. I had to turn the idle up just a bit bc its a bit heavier than the string I was using before. It will go through grass and thick weeds all day. I was able to cut back a wisteria bush, but it broke the string after a bit. If you are gentle it holds up well to cutting against chain link, but if you get too close it will get caught and then snap.The only con I had was my old string was bright orange and was really easy to see even during the day. This string is clear with a black core. I can't see it.9/10 It's almost perfect.

This is the best cord I have ever purchased for my trimmer. I trimmed over 300 foot of ditchbank yesterday and never had a single problem. Other cords I have tried wouldn’t even do 1/3 of my ditchbank before needing replaced. We have a weed called Tanzi, that is very tough once it matures and this cord went through it like a knife through hot butter. I would definitely recommend it and I will be ordering more when I need it. I wish I could find this tough for my handheld trimmer.

TL:DR - much better than the string arrived in the machine box. Great value, great performence. (I use troy bilt tb22m).Tip: since all the string failures I saw were within the U curve, inside the holder - When I face dry thick plants, I cut the string 1-2 inch shorter which improve even further its durability with small price in the cutting width and efficiency. I guess it is depends on user experience, but it worked for me. Instead of wasting 10 pairs over 0.5 acres (and I hate the frequent stops), I finished it using 3 pairs, while the third is still fresh for next round.

Quizá el único pero es que no es tan durable.

This heavy line stood up very well to the thick vines and shrubbery. Worked well with my Remington push string trimmer.

Este hilo es de excelente calidad, es muy duro y durable y perfecto para malesa y hasta arbustosPero asegurate que tengas la maquina (desbrozadora) adecuada porque este hilo es tan gruesso que no quepa en todos los modelos. Yo tengo una desbrozadora de 63 ccm con 3HP y nisiquiera en esta quepa, osea si tienes una maquina mas chica, este hilo no sera el adecuado

UPDATE August 2020-I updated this review to a 5 Star because this line really works well with my DR trimmer, and it really lasts. If I don't hit metal or a woody, perennial weed, like a pricker, the line lasts a very long time. Hitting harder stuff, it does much better than the OEM blue twist line, but it will wear down.The fix for the hard installation is this - grab a propane torch and a pair of plyers (no, you're not going to go "midevil" on anybody's rear end). Cut the line to length, and then use the plyers to insert this line about 1/4" at a time until it comes up in through the spool head, at which point grab it with the plyers and pull through. When you get ends done, get the line 90% snugged up, but not quite looped up into the groove above. At that point, hit line with a little bit of propane torch heat right where you need it to bend up and seat into the trimmer head, and then use the closed plyers to push the line into the groove. Pull line tight. That works great, takes only a couple seconds, and takes the irritation out of trying to get the line loaded. No soaking, no nonsense. The line never breaks at the heat points - at least not on my DR Trimmer.This line is good, and worth the extra bother getting it on._______I bought this to try in our DR Trimmer, which is an incredibly well designed machine. The cord fits, but you will need to use line pliers (or other basic pliers), to advance the cord a bit at a time to get it through the spool holes. HEADS UP - the cord is not square in cross section. It is rectangular, with a long and a short side. It will only loop up over the lock tab if you insert in in one of two possible orientations. If it is the wrong way, it will not loop up and stay locked over the tab in the spool on the DR Trimmer. If it is the right way, it will loop up, but you will struggle with it more than with the 2-line intertwined DR cord, which itself is not simple to install.So is it worth the extra hassle at getting it loaded?Well, I used this cord for 1 tank of gas, after going through the learning curve of getting it loaded on the spool, and I'll say that, when new, it definitely cuts better than the stock DR Trimmer cord. It cuts smoother and faster. I use the trimmer to cut 2-3 foot weeds in a field (goldenrod, ironweed, boneset, grasses, et cetera). This line, after installation, is an improvement over the stock line. As the cord wears, and the corners wear off, it cuts more like the stock line. After one gas tank, the line was the same length as when I installed it, and the last 2-5 inches had the corners worn off, so the line was more circular in cross section.I will update after a few more tanks.Definitely a labor saver, albeit not a huge improvement over OEM - but noticeable.
