17 in. 21.2cc Gas Brush Cutter is rated 4.5 out of 5 by 22.

Rated 4 out of 5 by from Good machine but needs a bit of improvement I bought the machine to use for extensive electric fence weed control. Works great except the strap and attaching points need to be improved. My previous brush cutter is a Husqvarna 225R. It too has the wide handle bar style handles. and it too came with a harness to support the brushcutter. The Echo SRM-225U needs a better body harness to carry the weight better, and it needs a more adjustable attaching point similar to the HusqVarna to enable different operators the ability to adjust it to their preferences. I also think the carburetor could be better protected though this has not been an issue yet. Other than those two points, of which I think is important, Ithink the Echo is outstanding.

Rated 5 out of 5 by from Excellent brush cutter Well worth paying a little extra to get a solid, well made cutter. I use to have a John Deere that never performed well. It comes with a brush blade that can handle more than advertised. I bought a extra blade (beaver blade) for bigger jobs and the engine size has no problem cutting through small saplings (2"). So far so good. Can get a lot done in a short time.

Rated 5 out of 5 by from So far, so good. I recently ordered the Echo 17 in. 21.2 cc gas, brush cutter and it arrived fast. All the parts were there, including goggles (which were a nice touch)! I have used it three times since I got it and so far is working fine. It took some time to get used to the handlebar but other than that, I have no complaints. I would say that putting it together wasn't as easy as I expected. The accompanying manual it's not that easy to understand so I needed help from a friend who knows more about machines than I do. Hopefully, this brush cutter will last more than two years, which is the time my old one lasted.

Rated 5 out of 5 by from great tool for the money i just got mine today and tried both typs of heads both work great and its light enough that it can be used for hours. If it lasts like my other echo equipment then there wont be anything to complain about. The only complaint i have is the hom depot dosnt carry replacement blades. Mabey they will stock them in the future..

Rated 5 out of 5 by from Quality, at a price Have used Echo products for years and have found them durable. Hopefully this will prove to be the same. Although higher cost than many other brands, seems well built and operates without problem. Some assembly required, but nothing major. Some of the factory installed bolt in the U-handle were required to be loosened for alignment(per instructions). Some were seriously over tightened and were difficult to loosen. All necessary assembly tools are provided, but the small Torx wrench that was provided broke due to the tension needed to loosen. Fortunately I have better wrench. This does include the brush blade which many dealers apparently remove then sell it separately. It is a $20 item. The included harness is rather primitive. For any serious use, I would suggest purchasing a more comfortable and substantial harness.

Rated 1 out of 5 by from This was one of the most disappointing purchases we have ever made. The instructions were not pro... This was one of the most disappointing purchases we have ever made. The instructions were not product specific, they were intended for use with six different models so certain parts may not apply to your machine but they are not referenced by model number. This was very confusing when trying to assemble it. The actual process of starting the trimmer was very awkward. Hold down the throttle on the handle (it does not lock) and pull starter cable all while bracing the trimmer shaft with your knee. It is a poor design. You really need 3 hands to accomplish this. After all of that, it would not start! After 2 days of this, it was returned. We will go back to a Stihl product, better design and better reliability.
