Customer Questions & Answers


Are there a number of attachments. Do they stay secure/safety factor. what is the guarantee on this item. I want to use it for thick bush and small bushes around a 2 acre parcel. If this is not the tool for me, please guide me to one better suited. I really liked the interchangeable idea.

You will have to get the attachment that cuts brush, the cultivator is only good for gardens and grinding up some compost pile material

this item is out of stock everywhere-will it be restocked or not?

Asked by: MisterFlash2
I believe it's been discontinued and replaced with a different model that's green in color.

Expand-It 2-Cycle 26 cc Trimmer Power Head is rated 2.3 out of 5 by 424.
Rated 3 out of 5 by from Good once carb adjusted When I first purchased this power head it had little power and did not like the throttle wide opened. I would have returned it had I not tossed the box it came in. Sounded like not getting enough fuel. I adjusted the the carb (I'm an auto technician). Now runs great. Factory adjustments should have never passed Ryobi's QC. Ryobi has done well for low level non comercial use tooling. I own many of their products along with Bosch (which is a superior product with a price). Unfortunately I would not recommend this power head right now to users who don’t want to make any adjustments straight out the box (they should not need too).

Rated 1 out of 5 by from Don't buy One word sums up this trimmer GARBAGE. Needed to replace my old Ryobi so I went to HD and picked a new Ryobi up. It would not stay running, took it back and exchanged it for the same model. Second one ran like a champ after two times using it. On the third time using it, it would not start no matter how many times I tried to pull it. Started my troubleshooting it had good spark and was getting fuel but would not start. I'm taking this one back also and getting a different brand. I purchased my first Ryobi and used it for 8 years guess this is what happens when you outsource to China, good brand names become junk. Won't buy another Ryobi anything again.

Rated 3 out of 5 by from Not good out of the box, but great after adjusting Out of the box the product worked for a little while and quickly became hard to start and would die if I gave it some gas. I was very frustrated with it - cleaned the carb, replaced the plastic pipes, filter and bulb with a kit, still no luck. This part is important- I was able to fix it by doing 2 things, 1: I had to adjust the hidden "high speed" ad "idle" screws. You can google this. I actually tapped them with a hacksaw so a normal screw driver could turn them. 2: I found the screws over the metal plate behind the actual motor would become loose which wouldn't allow for proper compression. I put some tacky glue (most prefer loctite) on the screws and tightened them down. With these 2 adjustments, the motor starts one the first or second pull and NEVER gives up. I think it's a tragic shame Ryobi released something which requires tuning after it's broken in, but I felt it was necessary for someone to post the method of correcting the problem.

Rated 4 out of 5 by from good product but some issues bought this to replace my old powerhead which finally gave up the ghost. Power is good, does a fine job. I use the string trimmer, brush cutter for bigger jobs and the tiller for small spaces. Sometimes a little balky to start, the idle is factory set too low and it's a real danger starting with the tiller attachment unless you use some kind of support to keep the tines off the ground. Air filter cover continues to fall off in normal use, needs a screw to attach rather than the plastic tabs. [This review was collected as part of a promotion.]

Rated 2 out of 5 by from Not a good value I bought 2 in 3 1/3 years. If you get 2 seasons out of these consider it a bonus. No parts available very sensitive carb and fuel system. In order to get 2 seasons, you really have to know how to completey winterize if it will sit more that 2 months. Ethanol fuel eats the fuel system alive if not used. Better to step up to the Toro for a few bucks. Toro is more power and will last longer. 2 Ryobi machines cost me $200 to get 3 1/2 seasons. Toro machine was $129 for power head and all Ryobi attachments worked with it. Toro cost $129 for 4 years and still going I'm surprised Home Depot even still offers this product

Rated 1 out of 5 by from Biggest piece of excerement I had an older Ryobi power head that had a larger engine, which lasted me for ten years, so I couldn't complain. I purchased this as a replacement last season. Hard to start from the get go, but it would eventually start. This season, however, (and I drain all my power equipment of gas at the end of the season) I have used it maybe 5-6 times, although I cut probably 15 times already. the reason I didn't use it is I couldn't get it started. It won't start now because I threw it over the fence and it landed in the street, shattering, due to my frustration with this Junk Oh, it's underpowered too. Time to buy a new quality head. Thanks for nothing Ryobi.

Rated 1 out of 5 by from Headache right out of the box Took it home and would only run if on 1/2 choke. Took it back and got a replacement. Due to bad choke lever placement kept choking out the engine when lever rubbed against my hip. Put a hook & spring on to hold the choke open. After 2 months the tension screw that holds the attachments stripped out and had to replace it with a hardened bolt & nut. At about 6 months the throttle cable slipped out of position and engine would only run at 1/2 speed. Had to wire the cable into place with wire ties because the plastic handle would not hold it in place any more. At about 1 year the fuel lines split and had to be replaced. At about 2 yrs. the drive shaft stripped out and would no longer run the attachments. Donated it to the waste disposal people this past week.

Rated 2 out of 5 by from A pain to start ... if you ever get it started It's amazing in the year 2012 that no one can create an internal combustion engine that starts easily. I bought a replacement power head this morning at HD, and inside the box was a used one. I went back to the store to exchange it for a new one. Upon getting it home, filling it with gas, it would not start ... there was no spark, nothing. Now I have to head back again for a third one. The problem with this setup is once you have the accessories you need, you are locked into their substandard head design.
