I put a Edgit on my new SRM 261T and love it. I had to make the hole a little bigger because of the gear box and add a washer to the head to fix the spacing but it works great. I can edge as fast as I can jog. It leaves a great looking edge and keeps flower beds deep. Creating a new edge is not a problem, I do not even have to go back once and retouch. I also like how it keeps the operator safer. Off topic but does everyone run there gear top speed. I was thinking any air cooled engine would last longer if cooled better by going all out all the time. I see alot of guys that are allways playing with the trimmer speed as they trim.
