Pros: Powerful, Versatile (many optional attachments), Easy to Use. Dual line trimmer.
Cons: Shoulder strap not included with trimmer. The "J" handle could be a little longer.
For a couple years, I had a weedeater brand trimmer that I bought at Wal-Mart. It finally gave out on me last season. Boy was I glad. I could now justify(to my wife) going out and buying a better trimmer. This trimmer was so hard on my back. My yard has several trees and a HUGE drainage ditch at the property line. The weedeater had a curved shaft and was a handful using on the steep ditch.
After days of looking at different trimmers, I decided to buy the Ryobi 775R.
Why did I buy this trimmer?
After looking at the advantages and disadvantages of different model trimmer, I came to the conclusion that the Ryobi 775R was the trimmer for me. It has a 31cc 2-cycle engine, straight shaft(easier on the back), dual line trimmer head which makes the trimming job so much faster and easier, and it has the ability to use other attachments like a tree pruner, edger, vacuum/blower, turbo blower, hedge trimmers, snow thrower, cultivator, and a brush cutter blade. You can have one tool that does several different jobs. The model that I bought only came with the straight shaft trimmer, but I plan to buy the vacuum/blower, hedge trimmers, and snow thrower in the near future. Prices on the attachments range from $40 to $140.
The performance of the Ryobi 775R is great. It cuts through most weeds as if they weren't even there. It has plenty enough power for the average homeowner and I wouldn't even be afraid to use it as a commercial weedeater. I think the shaft is 52" long which makes reaching under trees and hard to get spots pretty easy. I use about one tank of gas on my lawn each cutting. I don't know the tank capacity, but I do know that 1 gallon of fuel/oil mixture will supply several cuttings.
I'm using this trimmer for the second season. I still haven't had anything but good performance from this trimmer. It puts the other trimmers in its price class to shame.
Ease of Use
I have found the trimmer to be very easy to use. I do recommend that you go out and buy a shoulder strap because the trimmer can get a little heavy if you have a lot of trimming to do. I wish the "J" Handle bar was a little longer where I could keep my arm more to the side of my body. This just makes it a little easier for swinging the trimmer. But the "J" handle is still by far better than the loop handle that you find on most weed trimmers in this price range. Starting the trimmer is easy. Put the throttle on the "A" position(full choke), pull the rope a couple of times, move over to "B" position(partial choke). Pull rope a few times and trimmer should start. Then you move the throttle over to "C" position(open throttle). I have noticed that pulling the rope is very easy. It's not nearly as heavy as some trimmers that I have used. This is good for older people or anyone who has a hard time pulling the ropes on trimmers.
In my "epinion", I think that the Ryobi 775R is the best value in its class. You can buy a 31cc trimmer with a straight shaft and dual line head for $139 + have the ability to add different attachments on down the road. It is by far better than any weedeater in its price range that I have used.
