Rated 4.5 out of 5 by 84 reviewers.
Rated 4.0 out of 5.0 by Very useful. I have this, the chain saw attachment and the trimmer. This is a very useful tool so far. It cuts well in just about anything up to about the size of your index finger as long as you have the RPMs up. Anything bugger than a finger takes a good smash to lop it off. I have had it rotate on the shaft if you try something bigger, like slip 90 degrees around the shaft at the locking mechanism, but I was testing how well it works. A good tool. June 15, 2011
Rated 5.0 out of 5.0 by Ryobi Brushcutter Attachment We are using it on our Toro trimmer and it works great. We have a ditch that grows heavy with bullrushes at the back of our property. It is just what we needed to trim them down. August 6, 2012
Rated 5.0 out of 5.0 by Did the job I bought the brush cutter to get rid of some palmetto bushes that grow here in north Florida. It is difficult, and dangerous, to try and get underneath with a chain saw. This brush-cutter cut right through the base of the plants and I could do the job standing with my trimmer and this attachment providing the reach I needed. And the Ryobi Brush-Cutter fit my Troy-Built trimmer perfectly. January 15, 2013
Rated 5.0 out of 5.0 by Oh yeah, a must have for anyone with property! I've let my back yard go for the last 7 months Because I was unemployed and unable to afford to get my mower fixed. Today I cleared some of it with ease! Bunches of 1-2" pulpy stalks cleared with a single swipe. Gonna get a early start tomorrow and clear more, as I was having that much fun! Get one, you won't be sorry! July 24, 2014

Rated 5.0 out of 5.0 by Ryobi Brush Cutter I recently purchased a new home that backs to a forever wild area. The former owners. had let the heavy brush, vines and bamboo encouch quite a distance onto my property. I didn't want to purchase a gas cutter because of it's. weight or a battery cutter as I had problems with replacing batteries. on other tools. I was very impressed with the way this brush cutter devoured the btush, vines and bamboo. It did an excellent job in a very dense area with ease.. I did however, need to let the cutter cool off several times but I expected this because of the density of. the brush. I am completely satisfied with my purchase. January 20, 2015
Rated 3.0 out of 5.0 by Trimmer Attachment fine for basic tasks This attachment works fine for small brush, 1/4 - 3/8 dia. Blade dulls quickly, recommend purchase of back up blade to have on hand. This cutter also depletes battery life quicker than the string line attachment and the power loss is very noticeable when battery is down below 60%, but overall does a fair job. The shoulder strap that is included is not worth using, it's not long enough, causes the user to bend over when used and places to blade to close to users legs. April 2, 2015
Rated 5.0 out of 5.0 by The Blackberry Tamer! I have a Ryobi 25cc gas-powered trimmer. It came with a string trimmer attachment. Several years ago, my wife planted some blackberry plants along our driveway, and boy was that a huge mistake! These plants spread like wildfire, and began hanging out into our drive. The last couple years, I painstakingly cut them back with loping shears, and ended up getting stabbed with thorns all over. I saw this brush cutter attachment here on Home Depot's website, and knew exactly what I wanted it for. I went to my local Home Depot store and bought one, along with four bottles of the anti-Ethanol oil for 2-cycle engines. Ryobi requires that you use that type of oil to protect the engine of your 2-cycle trimmer from being damaged by ethanol that gas makers add to the fuel we buy. I brought the brush cutter home, and today I tested it out. Naturally, those blackberry plants were my first victims! What took me a day and a half of painful hand-trimming the last couple years went by in a half-hour! Needless to say, I was very impressed! So too, I was impressed with what came with this trimmer; namely an extra trimmer handle and a shoulder strap to take some of the weight off of you while using the trimmer. I already had a good handle on my trimmer, so I didn't need a new one, although I give props to Ryobi for including it. The shoulder strap and its bracket, I didn't have, so I really appreciated that! I was impressed as well with just how big of plants you can take down with this brush cutter, given a little patience and a light touch. We had a bunch of baby trees coming up along our fence, as well as some old growth honeysuckle that had gone wild. I was cutting trees down that were 1-2 inches thick. You just have to be patient, and kind of use a sawing motion with the cutter, and not press it too hard against the tree, or it will bind up. When you hear the engine start to bog down, you know you are pressing too hard, and you need to back off a little and let the trimmer get back up to speed. Right now, I am all worn out, but next weekend, I plan to go to my son's house and tackle a jungle he has growing in what is supposed to be his back yard. All in all, I am very happy with this purchase, and consider it to be an excellent buy! Thanks Ryobi, and Home Depot! April 11, 2015
