Rated 4.0 out of 5.0 by Morser Great product. Do not use Eco-Oil that came with.
Hello, This trimmer is great. I have the straight shaft attachment and the curved as well as many attachments (trimmer, tiller)
I bought this, and it came with two premeasured Oil bottles of this Oil that is "biodegradable" and "non toxic". It was very thin.
Do not use this oil. I returned one after the engine seized. I could still pull the cord but had to work on it a bit. I think this Oil is too thin and doesn't provide enough protection. Oil was spitting out the exhaust!
The next one I filled it once with that Oil and the same thing happened. I changed the Oil to regular 10x30 high end oil and it is great!
Great product. Not good Oil!

I bought one of these a few years ago. Used it one season until an intake valve bent (how the heck does that happen? - it has a governor to limit speed!). Had to pay for repair of course. Also replaced fuel lines that hardened and cracked. Of course, now, I can't get it to start even if I dislocate my shoulder and tear the tendons in my elbow trying. Yes, I store it dry and always use fresh fuel.
So much for that idea.

Rated 1.0 out of 5.0 by BradGoodman 3 words: "Terrible, Terrible, Terrible!!"
This unit is HIGHLY susceptible to hydraulic lock, which means that the motor will lock-up (after the unit has been sitting idle in a garage), not letting you pull the cord, or start it. After returning 2 units (each after using just ONE time) - I learned that this unit must be stored in a HORIZONTAL position to avoid this from happening. Since I don't have the room in my garage to store it like this - without re-laying-out storage for every other broom, shovel, rake, etc. which I already have stored VERTICALLY in my garage - this is a non-starter for me (no pun intended).
The other big issue is that if you run the unit with the engine turned (or upside down) as I sometimes do during edging - it will burn oil and smoke like CRAZY

Rated 4.0 out of 5.0 by hpiguy Powerful, Quiet, Clean Running, Fits All Attachments
This 4 stroke weed trimmer offering from Ryobi meets my expectations for an attachment capable piece of lawn equipment.
Not having to mix oil and fuel makes for easy refueling at any point during yard work. Use the same fuel canister you use for your lawnmower, snowblower, etc.
The starting instructions are simple to follow. Fill the crank case with the included oil and funnel, fill with regular gas, prime the engine, choke per the instructions on the choke lever, and pull the starter handle. This engine starts very similar to the 2 Stroke Ryobi powerhead already own, Only differing in that the choke on the 4 stroke model is not automatic. Using the choke lever is easy to figure out, it's clearly labeled and I like the way it is set up. This engine has a low gurgle to it's idle and throttle up. Quite different from the loud whine of a 2 stroke engine. It's pleasant to hear running and much nicer to have near you when cutting a lot of weeds.
Using any of the numerous attachments involves loosening the large attachment knob on the shaft, pushing in the locking pin and removing the current attachment for the new one. Snap the new attachment into place and re-tightening the knob. You're ready to go that fast. They lock in firmly and there is no slippage between the connections.
I have almost all of the Ryobi attachments for this tool already and they all work perfectly with this powerhead. There is no lack in power while using any of them. Being a 4 stroke, you have plentiful power on the lower end of the throttle, with lots of torque for hitting heavy brush and weeds.
The included curved weed trimmer attachment is built well and works smoothly. I would have liked to see a larger guard on the trimmer head. This small one works, but allows too much debris to go flying. My older attachment has a guard more than twice this size.
The product description says that there are two trimmer heads included. Well, not on the one I got. Only one trimmer head came with this machine. So I called Ryobi support as the directions said I should and after 15 minutes waiting on hold a very curt employee interrupted me while I was explaining the issue and told me that a second trimmer head is not included and that's that as far as he's concerned. I was not impressed. If this is how they deal with minor issues, I'm not looking forward to needing to use the warranty on this if I have to.
Other than Ryobi's customer service line being less than helpful, the machine itself is a quality item. It starts easily, runs well and has plenty of power to complete any task I gave it.
The drawbacks were the second trimmer head not being included in the box per the product description and I would have liked to see a nice shoulder strap included at this price point.
I have a large lot, with the house, two outbuildings, numerous gardens and beds. It usually takes a half tank in the 2 stroke model to cut all the weeds. With this 4 stroke model it took less than half that amount of fuel.

Rated 1.0 out of 5.0 by biggsteve Works great until it breaks
This trimmer worked great for me for (almost) two years, starting on the first pull and running like a champ. That is, until the plastic camshaft melted and stopped the engine in its tracks - permanently. I changed the oil and adjusted the valves according to the maintenance schedule, but the cheap construction of the device meant it was only a matter of time. If they are too cheap to put an air filter on it, you know it isn't built to last; I replaced it with a 2-stroke Toro and am much happier now.

Rated 1.0 out of 5.0 by lazarus Do not buy 4 stroke
They have yet to perfect the 4 stroke engine for a trimmer. I knew this was going to be trouble one the first pull when the the rope caught. It runs very low rpm, but had torque. Unfortunately if you tilt it or turn it over, the oil can get in the combustion chamber and then your out of luck. After only one use, it would not do anything but idle. As soon as you attempt to give it gas, it stalls.
Search the internet and see, these are known for this issue.
They have fixes but, who should have to fix a brand new trimmer to compensate for poor design. Went to Toro 2 stroke, and it ran great.
Sorry Ryobi, back to the drawingboard....

Seems it would have a lot of power with a 30cc engine... not so. Always seems like engine needs adjusting like it's not getting enough gas.

Rated 1.0 out of 5.0 by Notrimmerisabummer Terrible product, plastic camshaft
Have had this trimmer for roughly 3 years and used sparingly. Apparently the camshaft is made of plastic and melts. It is not offered as a replacement part and this renders your trimmer head useless. Buyer beware!!!
