Due to my "EX" Gravely dealer had so many issues out of banned from shop etc. only caved when Ariens/Gravely Corp came in and offered us a demo and banning us from dealership when I exposed him selling off out of date 2012's for full 2014 price, I must now make the transition to Sthil. I was going to invest in Echo PAS series, I use a older SRM 210 as main trimmer all other echo dealers are hour away as Gravely dealers were. Which unit do you recommend to replace my old unit FS90? Invest in multi attachment series? I just bought a new Deere so not looking to dive deep into a big price, just a little at a time if I go with multi attachment series. Feedback appreciated and Thanks a head of time.
