Rain Bird 6504 and 8005 rotors. The 6504 is a damn good head. We've used them for years on some large playing fields that we maintain and they have never let us down. The failure rate is very low and the nozzle performance is outstanding. I'm assuming that the 8005 is on par with the 6504 in terms of quality and performance.

even just bumping up to something like an i-25 will allow you to get all that turf watered quickly. we're in a similar situation here but having to use i-20 because a lot of the turf is wooded. Big thing to me is getting all that turf watered quick enough so the system isn't running all day. 80gpm for a well would be awesome

The 8005 looks even better than the 6504, in terms of useful features and durability.

If you can achieve 60 foot square spacing, that cuts the number of heads by more than half, compared to 40 foot spacing. Turning ten acres into a 600 x 720 foot rectangle, you would use 304 residential heads at 40-foot spacing, compared to 143 athletic field heads at 60 foot spacing.

Cost of heads would favor using the more common heads in 40 foot spacing, but there's the time to install each one, plus there would be more lateral piping with the smaller heads.

The client is trying to keep costs down so I think I am going to go with RB 5500 spaced at 45'. I did some figuring and I think it will be faster and cheaper to run a 3" main and build (2) 40 gpm zones and run them together than to build (1) 80 gpm zone because the entire zone could be pulled instead of trenched. Can you think of any downside to doing this?

This is a great topic GM, you no doubt have a plan in mind and from your past posts will be successful in the end.

I like the way you are comparing trenching and pulling as installation costs and soils disruption are paramount on instals.

Of all of the work I have seen of yours I'm partial to the big guns

If you can pull 2-inch pipe, you might work out something with a looped main.

Reading the specs, the 5505 is kind of the mini-me version of the 8005

Water Pressure?

No one has said anything about water pressure. Maybe the fact that the well is not in yet means you can have whatever pressure you want by choosing the right pump/impeller. But certainly available water pressure is a consideration in your design and choice of rotor.

And I am more than a little biased, but I agree with SoCal that the Rain Bird 6504 and 8005 would be great choices. The Rain Bird 5505 has the same drive design and trip mechanism and so Wet Boots is correct in that the 5505 is a smaller version of the 8005. (I led the team that introduced the 7005/8005 rotor in 2000. Someone else later introduced the 5505, but we designed the drive and trip parts of the 8005 so they would fit in a 3/4 inch case rotor (5505) to save development time and money.)

By the way, the naming convention of Rain Bird landscape rotors is that the first two numbers are the maximum radius of the rotor (when measured in compliance with ASAE 398.1) and the second two numbers are the pop-up height from the top of the case to the center line of the nozzle. (Not the top of the rotor as some of our competitors measure. Who cares about that dimension?)

We really like the 5505 which has been rock solid for us over the years. It may not be THE head for GM's project, but he knows his stuff and will select the right head for his application.

Anyway, not ONE warranty issue.....YET. LOL
