    The mowing crews are well-known for squashing heads down, which is why a 6" w/swing joints last longer before your crew has to come in and raise them.

    Heads being pushed around by really heavy mowers should have some sort of bracing. Easy enough to manufacture, in the form of a slip-on flange, and credit lowly Toro for putting them in their catalog.

    Could you post a link to this "flange"? In Florida sand I'm curious if it could hold or not.

    Hunter rotors just haven't been doing it for me the past few years..

    3 years and evident failure on high pressure systems... No I can't let it go.

    I have seen heads on systems that weren't maintained well that we're that low. But I think it is from the turf rising. All the systems here are pulled in so there is no settling.

    one thing i've noticed about PGP's is that the seal is inevitably GOING to leak, and it's usually only a matter of 1 year or 2. We merged with another company in town and they use I-20's exclusively. Here's why:

    1. Upgraded seal (i rarely see any that leak)
    2. Pop up 1" higher than a PGP (1" saves a lot of head raising)
    3. Slip Clutch (true 360 degree continuous turn radius)
    4. Able to shut the water off (we like this because you can flush the head before you put in the nozzle, also great to see if the head or fittings are leaking around it and adjustments)
    5. Stronger spring (don't stay up after watering)
    6. Check valve (great for the bottom heads on a slope)

    That's all i can think of right now. The only reason i wouldn't use an I-20 is if the system had very poor pressure. The springs are so strong they sometimes will not pop up with poor pressure. I used to only use PGP's, but now i'm a believer in the I-20. Fair warning, i do not have much experience with RB's.

    can someone confirm that the i20 is in fact 1 inch taller than a PGP? i've never actually measured the two side by side

    They don't pop-up any higher. They are both a 4" pop with a 7 1/8" body. They are the same so that you can swap the insides into each other for ease of replacement. You can purchase the I-20 in a 6" pop-up.

    We install PGP-Ultras in all installs except for sports fields, then we use 6" I-25's. I never have problems with leaking. They can be adjusted to 360* just like the I-20. They are non-stripable, and have a 5yr warranty too. They can even be ordered with a check valve if needed. The ability to shut off the head is a feature that's not worth the extra price to me.

    No more flange from Toro, and even if there was, it was only a fit for the original rotor bodies, like in the S600 and S700, and the 300 Stream Rotor. Too small for the T5 and other current models.

    No wonder that Florida sand could call for bracing heads. The Safe-T-Lawn company in Miami thought up the flange idea. Theirs were large enough to be awkward to work with, in the days before modern swing joints, but they could take over a ton of force without any head movements.

    Can't go wrong with 5000's.
