Sure... as long as the motor shaft accepts expand-it accessories you could use anything from that line.

Answer: 
It can only be used on the Ryobi units that are specifically designed to receive attachments. If your Ryobi weed eater can come apart at about mid shaft by releasing a clamping handle and pushing in a detent than yes it should work. To be on the safe side check your model number and ask the sales clerk if the attachment will work on your unit.

Answer: 
Hi wayner,
Yes, this attachment is compatible with all Ryobi split-shaft trimmers.
Since the curved section of shaft is removed and replaced with the straight shaft of the brush cutter attachment, the brush blade will work on your trimmer.

Answer: 
No! It specifically shows/states not to install saw blades on it.
From a safety point of view, it cant be done safely.
If you do choose to do it that way, keep every living thing away when you do. Plus the motor is not strong enough to turn the RPM's needed for a clean cut. Ask yourself if you would use your skill saw to cut whatever you would do on the brush cutter with a saw blade.

Different tools for different jobs. If you want to seriously cut something using the expand-it power head, get the pole saw attachment. It cuts great!

Answer: 
Yes, it is possible, but I strongly discourage you from doing so. That can be very dangerous. I have used that type of blade to cut away saplings. It is easy for that blade to get away from you. It is not at all forgiving! If you are cutting away small trees and very heave brush, a small chain saw would be my recommendation. It is more efficient and orders of magnitude safer!

Answer: 
I wouldn't say it would be impossible, if the attachment hole of the saw blade matches up to the shaft or if modified to do so then yes it might work. I don't think the trimmer would have enough toque to cut anything to heavy like a tree branch. Plus it would be somewhat dangerous. What if the blade comes shooting off !!!

No, and I certainly would not recommend it if you could. The existing blade is intended to cut with blunt force of the squared edge, much like the string cuts on a string trimmer. The blade is driven off of a cable, much like a speedometer cable. Putting a sharp edge on the existing blade, or a saw blade, would cause the blade to dig into whatever wood you might be cutting. That would over-tax the drive Read More
No, and I certainly would not recommend it if you could. The existing blade is intended to cut with blunt force of the squared edge, much like the string cuts on a string trimmer. The blade is driven off of a cable, much like a speedometer cable. Putting a sharp edge on the existing blade, or a saw blade, would cause the blade to dig into whatever wood you might be cutting. That would over-tax the drive cable, and probably snap it. Not to mention that if a spinning saw blade were to come off, you or someone nearby would be headed to the hospital. As it is, sometimes the existing blade gets bound-up in wood if you are putting too much pressure on the trimmer, and you can hear the engine bog down as the blade loads up. The best way to work this tool is to let its high speed spin do the work for you, and just apply enough pressure that it is contacting uncut wood, and still maintaining a normal spin speed. The factory blade was never intended to be sharpened like a knife either. Read Less

Answer: 
I've been able to attach it to two different Ryobi heads, a Cub Cadet head, and an Homelight head. I believe it's universal. The attachment drive is the male end (there is a small square rod inside the tube). All of the heads I have tried it on have a female square receiver inside the powerheads tube.

Well... you would because it would mean you have one attachment that would serve both needs. I have had "weed eaters" that did both before and they worked just fine both ways. So, is this answer a fact or opinion?

Answer: 
No. Why would you. If you had the Expand-it head, whether it be gas or 40V, the attachments are geared differently for different tasks. Buy the Straight string line trimmer attachment Model # RY15523. It's 60 bucks and works well. Be sure to order extra string line on-line as it's not carried in the stores yet.

No. The Toro 51480 is a electric trimmer that has a telescoping head. The shaft does not detach. 2 completely different tools. Look at the specs on line for your Toro trimmer. You're Toro trimmer is not made for attachments... from any manufacturer.

Rated 4.6 out of 5 by 161 reviewers.
Rated 5.0 out of 5.0 by Great on small brush and tall grass. Had to trim some overgrowth on a hillside at a home my wife was selling. My string line trimmer kept getting tangled up and bogged down in the heavy tall grass. Went to home depot to check out this attatchment and figured it had to be better than the attaatchment I was using. Boy was I right! It installs easily and sounds great when it gets up to speed. It cut through the tall grass and small brush without ever getting clogged. I was very please with the results and the amount of time this device saved me. Was well worth the cost. It's not going to cut down small trees but if you have small brush or tall thick field grass it will take care of it with ease. August 27, 2016
Rated 4.0 out of 5.0 by Works good but can get clogged As others have said, the blade is not sharp, but seems to cut just fine for me. I've used it on weeds and saplings up to about 1" in diameter. Tall weeds can sometime get wound up around the head but clears easily. I'm using it with a small Troy-bilt 2 cycle trimmer. Works much better if you get it up to speed and take your time. Swinging it into weeds as you would trimming grass will get it clogged MUCH faster. Oh, and I've done my share of running into things hiding in the grass - concrete blocks, old tires, etc. while clearing this land - no problems so far. August 16, 2016
Rated 4.0 out of 5.0 by Brush-cutter Attachment Excellent product, only available at Home Depot right now, and they have jacked up the price, from what Direct Tools Outlet sold it for. August 30, 2016

Rated 5.0 out of 5.0 by Spectacular brush cutter when coupled with a Renegade 8" blade. This brush cutter attachment performs flawlessly. Order some Renegade blades and you can trim limbs, weeds and small trees up to 2" in diameter. The tri-blade that comes with it works well on brush and weeds only. July 21, 2016
