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 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?Read more ›
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.
So far no problems at all starting it. In fact today was the first time this year and it started on the third pull. And it sits through some long cold winters up here in northern NY. Lots of power. I also have the brush cutter attachment. It will cut through some pretty heavy stuff, but if you're also cutting lighter grassy crap, it tangles in the cutter. I don't really like it because of that. But as far as thr trimmer goes, I'm reasonably happy with it.
UPDATE: While using the "Speedlock" accessory, which I pretty much switched to using full-time, it broke and so far I am unable to find a replacement to buy- even on the Troy-Bilt website.
