Title: Great power head, bad trimmer, low reliability and quality control
Review: I've owned a TB425CS for three years. I really liked it until the curved shaft trimmer cable broke and I couldn't get a replacement from Troy-Bilt. I tried a Ryobi universal replacement trimmer attachment but it was worthless. So, I bought the new almost identical TB525 (that's how much I liked the TB425). Right out of the box I noticed part of the plastic handle was broken. So I decided to at least try the trimmer attachment with my TB425 power unit. It worked for about 1 minute before the string completely disappeared into the hub. I retrieved it from the hub and tried again but this time the string fed out of the hub unrestricted and twisted around the shaft. Re-read the instructions and reloaded a few times with the same result. I could easily pull the string out of the hub with my hands. Returned product. Very disappointed with Troy-Bilt now.
