I'm going to pick it up tonight. I talked to the guy a few minutes ago. He said his father-in-law is old and just wants to get rid of it. It's too heavy for him and he doesn't like the straps. I'm guessing by the handles, straps, and engine size that it is commercial. I've been lookin for a starter trimmer and this looks like a good deal. 40 bucks. can't ask for much better price for a trimmer that runs good and being commercial, it might last me a while as a back-up once I upgrade. just wondering if anyone knows what brand/model it is?
