Hello:
I purchased a 2 acre property that has almost 100 Toro shrub rotors (i.e. non-pop-up) installed in the late 80s. The model numbers state series 300-02 or 300-03. They have the metal adjustable nozzles.
As I gradually update my isntallation I have numerous extra parts from the older 300s which I am trying to use to prolong the life of my existing 300 series system.
The problem is that I can not understand why swapping parts for the same model doesn't always work. I am trying to find a good explanation of how they should work, cleaned and restored. Inside the top of the head they have a rubber gasket with spokes, the metal nozzle and the plastic top itself which includes the set screw and can be seperated into two circular halves.
A typical symptom is the water comes gurggling or flooding out erratically instaed of the nice clean fingers of water you see in good working rotors. Any advice or pointers to good reference material would be most welcome.
Incidentally, I am gradually replacing them with the newer 340 shrub rotor, but it is hard to find this newer model (e.g. Home Depot in my area stopped carrying it). I like this unit alot, the ability to fit on both 1/2" as well as 3/4" risers, as well as the great selection of nozzles that come prepackaged is very convenient. Why don't the bigger retailers who carry most Toro parts include this line?
Thanks for your help!
