4 Cycle Straight Shaft String Trimmeris rated3.5out of5by27 . Rated3out of5bySam From DallasfromOk but there is an issue I bought this about 5 months ago. I would say it is a good trimmer. It starts easy and the various tools makes it pretty useful. The fact I don't have to mix oil and gas is really great. My problem is that I shut it down for the summer - I ran all the gas out of it so it would not get stale. When the leafs in Texas finally fell I bought the blower. I put gas in it and now the cap leaks. I cannot tighten enough. I went to this sight I tried to talk to someone. When I called I was transferred to a third party who was more than happy to sale me a new gas cap. The cost is $2.85 and $6.00 shipping so it is not that big of a deal but it is a pain in the neck. Home Depot did not have any replacement parts I could find. They may have them but there is never anyone there to help you.... Rated4out of5bydjf0927fromGreat Tool. Bought to use as edger and weed wacker and it works great. Could use a shoulder strap to make it a little less heavy (have pretty large lawn and take awhile to do the yard work). Looking to maybe purchase the blower attachment and/or pole saw. Rated1out of5byBegley79fromProblems Worked great.....twice. Third time I tried to use, evertime I throttled the engine it would die. After doing some research, this is common. SOME STRAIGHT FROM THE BOX. Very disappointed. Rated1out of5byshipwreckfrompowerful but not for long I bought this a few months ago and it worked the first time and was powerful. the second use it started did not make it through warm up died and never started again. I exchanged it for same product and it lasted a little longer. the shaft is bent from trying to get string to extend. Now rope will not pull. I see a lever that falls and stops pull wheel from turning. Rated2out of5byJustinfromRan great first season. Headaches after that. Bought this trimmer last year. Out of the box it worked great. I used to maybe 3 -4 times last year as we didn't get a lot of rain and grass really didn't grow. This year, attempted to use it and it ran for approximately 10 minutes and died. Could not get it to restart. Trained fuel tank and fuel filter came out and fell on the ground. the black hose from he filter to the tank fitting had degraded and was falling to pieces. Purchased new fuel line and plumbed it from carb to fuel filter. Trimmer stated on first attempt and ran for 20-25 minutes....and died. Could not get it to restart. You know what? My time is more important than dealing with this substandard, awkwardly designed trimmer. I have ordered a Makita 4 stroke trimmer and this one will be sold on Craigslist. Done. Dusted. Will never use a Ryobi again. Rated2out of5bypratt992fromGarbage Bought this machine three years ago and it worked great at first. Year three, went to start it and it will not start. Tried everything short of replacing the head. I am very disappointed with this, because we also bought the tiller and edger attachments, which are not useless. Save yourself a headache and buy something else. Rated5out of5bySlickfromDependable tools! I bought this Ryobi 4 cycle trimmer one month ago. I've done a great deal of work with it since. I only deal with Ryobi tools, it's top quality equipment, reliable, and efficiency is what I look for. RYOBI is it. Get you one; toy want be sorry! Rated5out of5byExcellironfrom4 Cycle Trimmer I LOVE IT! It has more power than a 2 cycle, and NO mixing gas! Easy to change heads from trimmer to cutting blade in 20 seconds. Very well balanced and powerful! Use only Ryobi products, they are tough and last. Rated4out of5byhectorfromit is better than the 2 cycle i bought it because the 2 cycle were going bad in just a couple of use. i got this like 7 months ago and still working fine plus the noise level is quieter, and it feels smother too. Rated4out of5bySleddyEddiefromEase of starting I am so glad I decided to go with the 4 stroke trimmer with the ease of starting this 4 stroke and not having to mix gas & oil makes for getting the job done ten times faster! Rated5out of5byRyobifanfromGreat weed eater I bought this tool a few months ago and have zero problems. It's quick to start, runs great and has been heavy duty enough to take care of three acres. Rated5out of5byAnotherCustomerfromWhat's not to like? Plain gas, no mixing, great power + attachments. I use the brush cutter and tiller attachments. Starts on one or two gentle pulls. Highly recommended. Rated5out of5byJerryfromEasy start and light weight. I bought this for my wife. I use a gas powered one and it is to difficult for her to start and to heavy. She love the battery operated one. Rated4out of5byBigV11711from Awkward, Hard to Service. Kill switch tempermental. On the positive note, LOVE NO MIXING OF GAS/OIL. Rated5out of5bydmitchellfromPOWER!! Love the power curve on the 4-cycle trimmer! Will never go back to a 2-cycle trimmer. All Aces. Rated4out of5bycarlettofromon /off button went out strong machine but on /off button quit working aka kill switch.

    What is the best way to cut weeds and grass using my string trimmer?

    • Keep your string trimmer tilted toward the area being cut
    • Pass the unit from left to right (if using a curved shaft string trimmer) and from right to left (if using a straight shaft string trimmer). By following these directional cutting paths, you will avoid having debris and grass clippings from being directed back at yourself.
    • Use the top of the line to do the cutting. Do not force the string head into uncut grass; this could cause the trimmer to bog down.

    NOTE: The line trimming cut-off blade on the grass deflector will cut the line to the correct length

    • Rotate the spool clockwise to wind the line on the spool until approx. 6 in. of line is showing on each side.
