Product Description

Amazon.com

The Troy-Bilt 2-cycle 31 cc clutch gas trimmer features convenient EZ-Start choke technology, which allows the user to simply flip the choke, prime the engine, and then give a slow, smooth, easy pull for a guaranteed start. The EZ-Start technology allows the trimmer's engine to engage with 55-percent less effort than most gas models. With its rugged 31 cc engine, the trimmer provides plenty of brawn to power through the most ragged, overgrown growth. The trimmer's professional-style straight-shaft, split-boom design gives easy access underneath low-growing shrubs. The trimmer cuts in a 17-inch radius and features heavy-duty, 0.095-inch dual lines with convenient bump-head line release.

When it's time to replace the line, the featured SpeedSpool line replacement system is exceptionally easy to load and rewind, all without removing the spool or taking it apart. The entire trimmer feels exceptionally balanced and comfortable in the hand, and the ergonomic soft-grip D-shaped handle easily adjusts for both right and left-handed users. The trimmer's engine and upper handle is compatible with other Troy-Bilt EZ-Link attachments (sold separately), a feature that allows you to turn your trimmer into an edger, cultivator, hedge trimmer, blower, or pole saw. The trimmer comes with all the necessary oil for immediate operation, and is covered by a 2-year limited warranty.

I started with the straight-shaft trimmer and soon added the pole saw for lopping off those low hanging limbs. Some pole saws have the motor in the saw and are practically impossible to use because they are so top heavy. The Troy-Bilt motor acts like a counter-balance to lighten the weight of the saw. Now, I've added the brush cutter which cuts tough weeds and grass, but doesn't do much for small tree seedlings more than a half inch in diameter. I've used it two full years for trimming grass, limbs, and weeds (sunflowers) and can usually depend on it starting with 1 or 2 easy pulls. I've had a couple of other string trimmers and hated them because they were hard to start, but the Troy-Bilt (MTD) is very satisfactory. I've recently switched to .105 line and it lasts a long time if you stay away from curbs and foundations.

(originally posted 6 Aug 07)
I bought one of these at Lowe's last summer, so this tool is coming to the end of its second summer of routine home use. And already the bump head has completely worn out, forcing me first to find (Troy-Bilt parts are not easy to find) and then buy a replacement. Previously I had a Homelite curved-shaft trimmer which lasted 13 years, so this item and its constituent parts are pretty sad by comparison.

As I've had to repeatedly work on and tend to the bump head prior to its going out, I also have noticed that the business end of the shaft seems to either be going out of true or bending, and the end of the unit is increasingly heating up. (Maybe this is the reason the bump head is wearing out; I have no way of knowing this.) I don't expect this entire unit to last much longer, new head or no.

I agree with other reviews that this thing is easy to start. The spring-activated clutch is a neat addition and should be retained. The motor is nicely contained, and the choke and throttle work easily and reliably. The motor has more than enough power to operate this tool. The noise from the engine is much less than other trimmers I've seen.

The tool is a bit heavy, but not too bad. It seems that they have not centered the weight well, and that the motor end is a bit too heavily weighted.

Also, I'm 6'4", and even though this is a straight-shaft trimmer, I'm still having to bend down to get the thing to the deck. I'll have to get a truly industrial trimmer for the next go-round, which probably will be soon

I got the repair parts, and they didn't fit. Why?

After struggling with a WeedEater, it is SO nice to use a trimmer that starts every time so easily! This item has been a joy to use! The only problem I encountered was a fussy bump head, which I got around by replacing it with a fixed line head I picked up for a few bucks. The easy start feature, nice even idle, comfortable handle, and well balanced design makes this model perfect for my needs. Did I mention it was easy to start?!? Good job Troy-Bilt!

Tnis string trimmer worked well out of the box, those it was *much* heavier than my previous Weedeater Featherlite. It did a better job than the Featherlite in long weeds, but still bogged down from time to time, which surprised me considering the unit's heft. The buump-and-feed mechanism was also less than ideal, causing me to have to stop the trimmer frequently to "manually" let out more string.

But these quibbles became moot after the trimmer ceased to function after using it on a very hot day at the end of July. The unit will now only run for a minute or two; after warming up it stalls and cannot be restarted. It would appear that it overheated on that hot day and is now seriously damaged (and yes I did use the proper 40-1 oil mixture).

BTW, the Troy-Bilt gas trimmers are manufactured by MTD.

I purchased the model TB70SS String trimmer with cultivator attachment. All works well except for the line feed heads that came with the unit. Does the bump feed let out line? Absolutely, but the bump head uses entirely too much line. Never had this problem before with any other trimmer. The entire spool (15-20 ft of line) empties before the job is completed. I tried the bonus fixed line head that came with the unit but it is useless because the line keeps flying off the head while in use. I even went back to Lowe's to ask and ensure I was attaching and locking the line correctly. I am disappointed as this is my first Troy Built unit. I never had this problem with other brands in the past 20 years. I asked TroyBuilt on-line if they had any suggestions. They gave me their warranty blurb and told me to go to an authorized repair center. Did they not understand that there is nothing wrong with the unit except for their design? I guess I will get a universal head and try that. Not impressed at all with their answer or on-line support.

It's a cheap trimmer, if you expect it to only last a couple of seasons before you get fed up with it and want to replace it with a better model, then by all means, go for it. Second season in my pull start line broke. This isn't covered under warranty, and it took me a little more than 3 hours to replace it. A real pain in the butt.

I'm not really happy with the power either, it seems to bog down a lot. I hope to get 1 more season use out of it before I start looking for a replacement.

Oh, and by season, I do mean about 4-5 uses a year. Yeah, that's how fast the line broke on it.
