Pros: Tough, powerful, rugged.
My landscaping company had owned echo equipment for about five years before I decided that I would try the Shindaiwa T270. Until then, I was using an Echo 2100, and 2400 straight shaft trimmers. I knew that I needed another trimmer for my lawn care business, and decided to look around. The larger companies in my area were split about 50/50 between Shindaiwa and Echo. I made the decision to buy the Shindaiwa after talking to the factory rep at a local open house at a Shindaiwa dealer. The things that I found appealing was that the Shindaiwa was lighter and more powerful than the Echo 2400 that I was currently running, and it came with a seven day money back guarantee.
I bought it, and the first day out it ran out of string. No problem, I expected that, but the head was more complex than the Echo. It had three or four parts in it that could be lost or broken. About a half hour after I had re strung it with my own .095 string that I had been running in my Echos, the string would not advance at all. I took the head assembly apart to find that the string had melted together inside the trimmer head. This is in addition to the annoying vibration that I was feeling all day. I decided to take it back. The dealer cut me a check that day no problem on that end.
I still needed a trimmer to replace that one, so I bought an Echo 2601. This is a commercial trimmer It is lighter, more powerful, smoother, and faster than the Shindaiwa T270. That was last year, and I am planning to buy two more this year and get rid of the Echo 2100. It is a great all-round trimmer. It is comparable to the 2400 in weight, but there is no comparison when it comes to power. This is just my own personal experience, I have spoken with several Shindaiwa dealers and they have not heard of the melting problem even when using the same line as I was using.
