    Did you note the golf course? Pretty impressive.
  2. They need to take a tip from the GC and cross cut. Pretty cool area. I like your original idea GM. Do about 8 or so taps into the 4-6" with the 1.5 and come off of that with the rotors. It can all go in the same ditch. I would consider impacts though. You can make more adjustments. Just me I guess but I find impacts superior to gear drives.

    Yeah. Nice work there too.

    Better shot of the fine 90's.

    Very cool. Didn't dig too deep, but don't look free. :mad:

    I don't think I could use impacts because the heads need to retract for mowing but they don't cut it short so I need a pop up of at least 6".

    Exactly, and will greatly affect your price.

    I think you connect about every 100 feet with 1-1/2 poly for an inner loop. Gives you about 20 gpm per connection, assuming everything balanced.
  8. makes sense. I was thinking they'd be anchored to the fence as permanent risers.

    Looking at some friction loss charts I see that 1 1/2" PE can safely handle around 30 gpm. If fed from two sides that gets you around 60 gpm.

    I think you go for near-zero losses for the inner loop and the feeds to it.
