UPDATE
I dislike the 3500 rotors...I used 17 of them on a job last week and hate the way they adjust, hate the way the spray pattern works in other than fully open position...and hate the way it is easy to break the adjustment screw.
If you haven't bought them already, go with the PGJ...sorry for the poor info.
(thinks briefly about recalling those square-pattern sprayheads that could easily cover a 20x20 area, before he notices the black van of the You're-Not-Using-Enough-Material hit squad lurking around the corner) [xx(]
1 vote for Hunter PGJ rotor here. You're looking at about 15 spray heads versus six PGJ rotors to do the same job. 3 rows of sprays heads versus 2 rows of rotors. And depending upon what kind of pressure and GPM you've got, perhaps 2 circuits instead of 3, or hopefully 1 circuit instead of 2. If you can get 15 lawn sprays on 1 circuit, you're in great shape.
I vote for RB3500.....perfect head for this area.
rainbird 3500, hunter pgj, or mprotator

<br />6 rotors total- rotors at each corner and one each halfway along the 40' side. If you used sprays you'd need 15 to do it right.

<br />Spray heads. Either the Hunter Pro Spray series or the Rain Bird 1800 series. Your spacing will vary depending upon your available pressure and the nozzles used. Generally, you can get 10' 12' or 15' nozzles as the most common types. You want to have head to head coverage, meaning each head sprays to the next and so on..

Thanks for the reply but i was thinking of putting 4 rotors on 4 corners, if i use spray heads, i will need a lot of them, dont you think? about 6?!?!
