Hunter Ultra PGP-04 4 inch Pop-Up Adjustable Arc Rotor
The PGP Ultra takes the foundation of the best-selling PGP Rotor and raises the bar with a variety of new features developed over three decades of research, customer feedback, and lab testing. Among the most notable improvements of the PGP Ultra is its non-strippable drive and automatic arc return. These two features work to allow the turret to be turned without causing damage, and return the turret to its original arc regardless of where it is turned. Other advanced features include 34 nozzle options with several radius choices, and a headed slot and set screw. The diversity of the PGP Ultra offers system installers an array of efficient options on any site.

use the white plastic key to pull up the head. it inserts into the hole in top and locks in place so that it acts as a handle to pull up the rotor part. You will notice that the rotor can rotate to the left and to the right.
the right stop is fixed if I remember correctly. the leftr stop is adjustable. so install the head by screwing onto the threaded pipe in the ground. Make sure you do not let dirt fall into the line.. you will have a hard time cleaning the system. once you have handtighted the rotor housing, turn the housing so that the right stop is where you want the head to spray. you will have to use your best guess as you tighten since you will be looking at the arrow on top of the rotor. have it point to the edge of the spray coverage. then turn the rotor left. the factory presets the rotor at 180 degrees. you may want more or less. so once your have filled the hole and set the rotor, turn on the sprinkler and observe the actual spray arc. then take that plastic key and insert the tab into the + - hole. if you want to increase the arc turn the key towards the + and if you want to reduce the arc turn towards the -. I find that it works best when the rotor has been manually turned to the stop and then back off a bit and then turn the adjustment. 1/4 turn will move the arc about 4 feet or so. then twist the rotor to the opposite end and then back halfway and let the water pressure move the rotor to the new stop setting. adjust as necessary.
Several differences. The one I noticed the most is that the ultra has more spray pattern nozzle options compared to the PGP.
The nozzle hold down screw can be put part way into the water stream to give a wider but shorter stream from that rotor. Be careful not to turn it in too far, it will fall out.
Needless to say if the whole zone is either too wet or too dry you need adjust the run time for that zone.
If you are fast and good you can turn the rotor off from the top. That will keep the rotor extended, making for an easy swap of the nozzle.
