Rated 1 out of 5 by from Looks good , but not very durable I bought this unit around august of 2016 and have only used it 4 times since then , the last time I used it was at the beginning of the mowing season at my mothers house, before I used it I went to my truck picked it up and heard a rattling in the unit I thought maybe a rock had intruded the engine housing somehow so I took the unit moved it around a few times and out comes a piece of aluminum have no idea where from I thought that was it and then I heard more rattling so I moved it around again side to side over my head and then here it comes 2 more pieces of aluminum no idea where they are from so I moved it around some more and I heard nothing so then I proceeded to check to see if it would run and it ran ok so after I used it to trim I went home and called troy-bilt told them what happened and I was told to take it to a repair shop here in town to have it looked at to see what was wrong with the unit so I agreed I still have to take the unit the unit is still under warranty on the bottom of the unit the date of production sticker says 3 / 2016 but what I was told I was to show proof of purchase not really sure if I even have the receipt anyway the unit does not have power to cut through weeds when you hit the weeds it starts speeding up slowing down speeding up slowing down and then it dies this unit is not that old maybe 8 months and only used 4 times since new not really sure what to do with it if I wanna get it fixed or trash it seems like a complete waste of money but I recommend buying something else to all you who read this. oh and one more thing this unit has never been damaged in any way never been dropped no damage of any kind .

Rated 1 out of 5 by from worst piece of junk ever Right out of the box it didn't run very well. bought it in june, used about 5 times. finally took it in to authorized repair shop. thought it was a carburetor, of course it wasn't covered under warranty. 1st one they received was wrong, next one they put on - will only run for about 4 seconds. they've had for about 2 months now still waiting.

Rated 1 out of 5 by from Don't buy this model Don't waste your money on this piece of junk. Brand new unit bought from their site. It won't stay running. Dies when the throttel's pressed. Sent emails to customer service with no replies. Really disgusted. Won't buy a Troy bilt again. Too bad, I have a snow blower that's awesome

Rated 2 out of 5 by from TB635 EC - Disappointing Purchase Purchased from Lowe's April 2016 including multiple tool attachments. I bought this because of the brand reputation, the 4 cycle engine and the interchangeable tool attachments. My only positive experience with this was the interchangeable tools. It was difficult to start and got progressively worse with each use. Used it approx 7 times before it started overheating and leaking oil, now it want start at all. I even bought the canned fuel that was suggested in the manual. Hopefully I can find a more reliable product that accepts the same attachments. The attachments worked will with the exception of the difficulty to open the string housing.

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 didn't last a year I am pretty sure we bought this a year ago. We don't use it every time we cut the grass so I am sure it was only used a handful of times. When we got it out of the garage it was leaking oil from inside the unit. I am sure I registered it but can't find out when. I always try to register anything we buy that has the info in the box. I will be sure never to buy this brand again.
