Rated 1 out of 5 by from Disappointment I bought this about 1 1/2 years ago. From the start, I had problems with it starting. The past 6 months the product would not start due to the pull string assembly not working. The string would pull out and not retract. When I took a closer look this is what i found. See first image. Next I bought the ez start bit to start the trimmer. It worked four times and then It would start again. I took another closer look and this is what I found. A broken spindle and fly wheel. See attached photos. I'm sure that I am not the only one with this problem. I hope that you can use this to improve your product.

Rated 1 out of 5 by from Fell apart This worked well for about one and a half years and then the pull start mechanism fell apart trying to start the trimmer. Pieces literally broke up when I pulled the cord.

Rated 1 out of 5 by from Hard to Start I have replaced this trimmer 3 times because I have all the attachments and I have no choice. It is hard to start and the starter cord mechanism is not very good. It does not engage sometimes. Bought attachment to start it with a drill and it won't start that way for some reason. It works well with the attachments which I like but the things I have mentioned gives it an overall poor rating in my book.

Rated 5 out of 5 by from Great Equipment, Very Reliable and Very Versatile! Out of all of the String Trimmers I have owned, I have really loved this one the most! The 4 cycle is great with starting and runs great! No need to mix oil and gas any more which is a BIG plus! I have also bought the attachments so I now have multiple tools all in one!

Rated 3 out of 5 by from Not that happy having trouble with the pull start .I purchased a new pull start but the cord still will not recoil. So i had to purchase the jump start tool.So if you purchase this trimmer you need to get a jump start tool.

Rated 1 out of 5 by from Do not buy this This is far & away the worst string trimmer I have ever owned since they were invented. It is nearly impossible to re-string since the directions in the manual are wrong. They must be meant for another trimmer. I finally figured it out after looking on Youtube where I found man, many other complaints of the same nature. It is difficult to start at best; even using the electric jump start which I purchased sending good money after bad. Even then; it stops if you turn it the wrong way in use. I bought it last season, wanting a 4 cycle model, used it one season with the same issues. I should have taken it back immediately but procrastinated. It sometimes takes me 40 minutes to get it going before I can do the job & then I'm exhausted before I start. Troy Built should stay with what it does best and keep out of the small wares. I own a Troy built Snow-Blower that works perfect. NEVER AGAIN!
