Rated 1 out of 5 by from Year old and doesn't work. Really disappointed in Troy-Bilt. Use to be a quality brand. This trimmer lasted a year and stop running. I didn't register the product and couldn't return it so I did some research and found out that it could have been issues with the carburetor and/or fuel lines so I replaced them. Ran for about 30 minutes and stopped working again. Won't start. I tried to post a review on this earlier and the admins didn't approve of it. Just trying to save others some grief and hopefully encourage Troy-Bilt to improve their product quality. DO NOT BUY.

Rated 1 out of 5 by from Multiple problems with only 6-10 uses I bought this trimmer liking the fact that it was able to use multiple attachments and it was straight fuel. During the first season the c-clip that held the catch for the start pull bent. I had to take it apart to figure this out and replaced it. On the next usage the second one bent and I had to replace that as well (good thing it was a two pack of clips). This season the head on the trimmer wallowed out and is now loose, taller grass will now completely slow the head spin to a crawl. Essentially making the tool useless. I will obviously have to either buy a new trimmer extension (highly unlikely) or buy a new trimmer. I didn't even get my moneys worth out of it before it was useless.

Rated 1 out of 5 by from Junk I bought this trimmer a half a season ago and the head is horrible I have to stop every 5 min and restring it. I spoke with a Troy engineer last year and was told I was sent to wrong instructions with my trimmer. I followed the new instructions and the performance stayed the same. I am extremely disappointed with this product and will not purchase or recommend it to anyone

Rated 3 out of 5 by from Watch that starter. Bought this model at the end of last year. Used it twice due to hiccups with the trimmer. First, the swing arms that engage the recoil start have VERY weak springs and would not engage the crank. Found that out after thinking "oh, the jump start option should fix it", buying one and using it to no avail before taking it apart to find the swing arm issue. Also, the insert for the "jumpstart" strips out easy. Second, fixed the springs, pull-cranked it and started it right up. All was well in the world. Finished the work, set the trimmer in its rack and enjoyed the day. The third time, experienced the same symptoms as the first use. Took the trimmer apart only to find one of the swing arms missing. Thought, no problem, we'll order the part. Nope. Part not available. Not extremely happy with this model's performance. And where can I get a new crank case for it?

Rated 1 out of 5 by from first experience This is the first time I have purchased a Troybilt product. I have had nothing but bad experiences with the tool purchased, and I am here buying parts that failed. This tool is less than 1 year in my possession.

Rated 1 out of 5 by from Sales Ad sounded to good to be true and was. I bought this in July 2018 and it broke May 2019. It was always hard to start even with the Jump Start. The line trimmer never feed the line out right and the I was never able to load the line according to the instructions. At the end of May it just quit and there are parts rattling around when you pull the cord. And don't call customer service unless you have an hour to spare. I only gave it a one star rating because I couldn't go any lower. There are very few warranty repair dealers in Montana.

Rated 1 out of 5 by from May lead to the end of my marriage First of all my wife bought it for me for Father's day last year when I didn't ask for one. That's like me buying her a vacuum for mother's day. Everyone days I should leave her just for that. Anyway it's awful. Impossible to start. When it starts it's hard to keep on. The feeder is awful and you need to be a nuclear engineer to replace it. I've never owned anything so awful that I had to create a login for a website just to steer people away from this. I'd rather use scissors and cut one blade of grass at a time.

Rated 1 out of 5 by from The string trimmer attachment worked once. I bought the trimmer and 2 other attachments: lawn edger and blower. The string trimmer worked the first day I had it, but ran out of string in 15 minutes. So the next day I bought some more line and had to remove the head as all the old line didn’t come out. Removing the head is no simple task, the manual makes it look easy, it isn’t! Put it back on and put in new line as directed. First of all the engine never starts easy, ended up buying JumpStart as I was getting wore out from pulling the starter rope. The “BUMP” trimmer seldom works and I end up having to remove the bump head to pull more string out. I’ve replaced the line several times meticulously following the line replacement instructions, but no, the bump feed still doesn’t work!!
