Dan,
How would you "add 'extra' spring tension" on that kooky limit roller? Drill a hole on the bottom of the arm and fasten a spring to that point then the gutter? Kinda sorta like a Montgomery limit?

Jim,
I have never seen a US roped hydro in all the years I worked for them. Hope it runs as least as well as Otis' unit which is not without what seems to be some inherent problems (Speaking of inherent problems...gotta get the mower out and get busy).
And where did that "NEWBIE" thing come from? I just noticed it!
