Echo String Trimmer SRM-225 Review

Straight shaft or curved? Which is better or rather easier to use? I won’t bother you with the explanation of each, but know this, I prefer straight shaft trimmers for their conventional design. The Echo String trimmer SRM 225 is a 2 stroke 21.2cc straight shaft gas trimmer costing less than $250 with three important features that helps it get on my list of must have garden tools.

Arriving preassembled, it packs in a healthy length of cord so you won’t need replacement the first few time. When the time does come, no need to remove the housing that holds the reel as it’s all a simple matter of recoiling the reel using the rewind torsion head. Oh! the Vortex 2 stroke engine takes almost 30 percent less strength to start. No intricate starting mechanism and zero preparation time – this trimmer starts on the first pull, guaranteed.

In-Depth Review of the Echo SRM 225 String Trimmer

My first impression of the Echo SRM-225 17 inch gas trimmer was that of a conventional trimmer with shiny plastic parts. In all fairness, I have to disclose I am predisposed towards traditional lawn care equipment (read gas tools) solely because they offer a lot more power and possibilities than electric counterparts. The Echo SRM 225 weighs just 12 pounds, which is rather light considering it has a 14.9 oz. tank capacity. In other words, it is a lightweight nimble package. Of the top, three features that caught my immediate attention were its 59 inch long straight shaft, simplified starter cord and the automated rewinding reel feed.

Starting this beast takes a single pull and at first I thought Echo exaggerated the fact that their device needs 30 percent less force to turn over, but after couple of weeks I have to commend them on somehow managing to make the start so effortless. Just out of curiosity i wonder if it has some sort of a half-way automated starter hidden inside, I mean it really does start easy!

Moving on, I always prefer a straight shaft as it allows me to maintain the cut height better and hence match curb regions with more cleanliness to the rest of my lawn. And, this being 59 inches long is more than enough for any lawn. As for the auto rewind reel reload, it eliminates the need to open up the cord casing for a reload. Basically, in the few weeks I have had the pleasure of trimming with this electric weed whacker, I developed a compulsion to take it out every time I landscape – a primary reason why I must give Echo SRM 225 review the top honors.

  • Being so light even with a full tank, carrying it over a large yard is no biggie
  • Patented proprietary Echo I-30 starter reduces 30 percent of effort needed to start on the first pull
  • Lots of power, 21.2cc 2-stroke Vortex engine ensures clean cuts against the toughest grass strains
  • Reliable, this weed whacker does not suffer from unexplained complications
  • Starts even with a leisurely pull, really takes 30 percent less effort
  • Sturdy and rugged plastic body, leaves no doubt on its durability
  • Re-loading string and opening the cutting head is a breeze
  • Bump feed maintains constant length of reel until it runs out
  • Comes preassembled, you only need to add the oil-fuel mixture to start

  • A shoulder strap for carrying it around the lawn would be welcomed
  • Power and weight makes it unsuitable for commercial use
  • Shield could have been a tad wider
  • Plastic tamper proof plug may break over time
  • 2-stroke engine is noisy and polluting

Impressive Trimmer!

For this Echo String Trimmer SRM 225 review, I chose my neighbor’s field rather than my own since he tends to neglect his a lot and I thought it would pose the perfect test subject. Day 1 till today, this weed whacker has nothing but impressed me. Just keep a stash of line handy and re-spool it to keep it whacking away. A word of caution, don’t tilt or get too close to the ground with the engine as it will flood immediately, being a two-stroke engine.

      ECHO is an awesome USA based company which started about 40 years ago and managed to become a well known worldwide leader in the development and manufacture of professional-grade, hand-held outdoor power equipment for both the commercial and homeowner markets. The company offer good and affordable products, so I can understand you´re being an “ECHO-fan”.BTW, our cat is called Tintin (like in The Adventures of Tintin), but I like Echo too, Maybe next time?
