PGP Rotor arc no longer adjustable
I am unable to adjust the arc on one of the Hunter PGP rotors....I tried with the sprinkler key and then with a flat head screwdriver...perhaps some soil got in there or the adjustment screw is stripped....any ideas? If the screw is stripped what needs to be replaced?
Thanks!
