Rated 1 out of 5 by Wow I purchased this even after reading the bad reviews thinking I would like to see for myself. Reason was that it felt really good to hold and I liked the idea of not having to have two separate gas cans since this uses straight gas. When I got it, I followed the instructions exactly as written and was pleasantly surprised that it started and ran amazingly. It cut well and was easy to use until I went to shut it off. When I pressed the off button it wouldn't shut off. I ended up having to tip it back and forth until it finally stalled itself and shut off. I decided to give it another try, started it and same thing, wouldn't shut off. Did the same thing to stall it and put it away for a day. Next day I tried to start it and the pull cord would not budge. My advice...don't buy this. Very disappointed! June 2, 2014
Rated 4 out of 5 by RYOBI 4-Cycle Straight Shaft Trimmer We bought the 4 cycle timer and on my first run I had a problem with a lack of power and steady power inter ruption (miss). I decided to go back and follow the instructions, prime the engine the 10 times as recommended in the manual. It cleared the air out of the fuel lines and the trimmer preformed flawlessly. During the first run I did have a problem with the string feed. However once I purchased a reel of string and loaded it into the trimmer head it worked well. Ryobe could have provided a 10 ft. trimmer string and saved me the difficulty I encountered. I am quite happy with the trimmer and would recommend it. June 2, 2012
Rated 2 out of 5 by Easy To Start but Oily Mess This is a powerful unit, but the advantage gained by having to use straight gasoline is completely lost by the "oil in the crankcase" concept. I filled the unit up with oil and ran it only to discover that tilting the unit to get at crevices and hard-to-reach places causes some sort of oil overflow/spilling to occur. Also, the unit emitted a massive cloud of smoke, presumably because too much oil got into the cylinder. Also, filling the crankcase was a pain as it was hard to do without spilling. The unit was powerful enough to take out plenty of weeds and grass, but it's going back to the store in half an hour. I'll probably go for a 2 stroke Echo instead. I'm pretty happy with their leaf blower. May 28, 2011
Rated 1 out of 5 by Disappointment I have had a number of trimmers, 2-stroke and 4- stroke. My last one siezed, so I paid a little extra for this 4-stroke, knowing the name and bought it at Home Depot. It ran well the first season, but it's first use this year and the choke lever snapped off, making it useless. Even before that, it runs badly and I suspect the carb is plugged. I had fresh gas and stabilizer in it for winter. Shouldn't happen in a new machine. I was also disappointed there is no air filter in this unit. That can't be wise in the long run. I found out today the service centre here can't get a replacement part, and he's trying to butcher one lying around for one. Very unhappy owner of something that should last 10 years. May 24, 2011
Rated 4 out of 5 by exalent preformance,but ...... i bought this product b/c ithas a 4 stroke engine,i own a 4 stroke outboard motor,and know they are quiter and create less odor then 2 strokes,but are usually hevier. this is a light machine(lighter then most 30cc 2 strokes). beware this machine has unusually strong ressistance on the pullcord. if you use the funel provided to oil/refual, it always starts in under 3 pulls. now the bad, if you cut tall grass near a fence with it ,the grass gets stuck in the string head and seomtimes makes it stall. i highly recomend buying the pruner/chainsaw atachment,as well,as the hedger atachment for it(3 tools in 1, all else you need is a lawnmower). if its droped return it while you have the chance the engine enternals crack easly.
