I have ran across a few of these in the last couple of weeks. They were installed at least 15 years ago and still working.

My question is - Can you compare these rotors to Rain Bird or Hunter as far an better product for water conservation?

They are probably the most reliable rotor head still in production. Nothing is better for retracting when the watering is done. The fact that the entire mechanism is encased in a basket filter gives it extra protection from any stray grit in the water. (not for sandy water, though, or you are endlessly cleaning screens)

The 300 "Stream-Rotor" was invented by Ed Hunter, unfortunately, he was a design engineer at Toro then, and they had the rights. It still stands as the finest rotor ever made,especially if it's used in a turf application with foliage and trees. The reason most contractors don't use them is they are very picky about head-to-head and pressure. Plus, done right, it's SO pretty to watch work!

neat to watch is right....

ive always liked them.

the smaller nozzle 01's always stopped
turning before a 03 nozzle.....

Their biggest weakness was spacing issues. There were the -01, -02 and -03 nozzles... I think they were at something like 15 to 18, 21 to 24 and 28-32 feet?

A landscape architects spec'd them for a couple of maintenance jobs I had in the early 80's with no regard to spacing in turf, which soured me on them. We kept changing nozzles and the dry spots just moved around a little.

Then later they came out with an adjustable radius OMNI nozzle, but the cap would blow off if you as much as breathed on it.

The shrub version made a lot of sense on hillsides of ground cover though... when spaced and timed right.

Those oil bath gear drives used to quit regularly too.

What was the name of the one that Ed started Hunter with.

Instead of metal discs it had the plastic "cone" nozzle much like the MP Rotator now does (as I recall.) Did Walla-Walla have to license that from him?

Ran across an interesting old article about Ed Hunter:

When I said "started with" I mean the rotor with streams similar to the 300 after he left Toro... I had never heard about Moist O' Matic until today.

I do like stream rotors, never thought about it but they do last a long time.other than that I can't stand toro irrigation products.

Moist o matic was the riverside based company toro bought. The stream rotor was an awesome head back in the late 70s. Space them every 18' and watch them run was as cool as it gets. They had a bigger version of the stream rotor whose name escapes me.

I think your talking about the Toro XP rotor. Had two opposing streams, a short and a long throw. Not too bad a head for it's time.

not the XP-300 ~ it's an older head, that was designated "320"

"Ed's folly" was called the "Type S" and was a miserable attempt of Ed's to relive his glory days with the #300. Toro tried plastic arc disks in a #300 clone, called the 345, I believe, it too failed. The variable arc nozzle was stupid, as well. Properly designed Stream Rotors with the 02 or 03 nozzle are still my favorite of all time. The SR is a water-eater, no doubt, so they made a 63 and 93 nozzle with fewer streams that lowered the gpm demand.

Strictly on precip rate, an 02 nozzle matches with a 93 better than the 03

I did a system with all Stream Rotors, during the walk-through, the client said, "It's like sitting around a campfire." After a few minutes, he also said, "I don't think you ought to look at these too long."

Posted via Mobile DeviceThat's the 320 - I probably have some stored away - it was the gear-drive heavyweight champ of riser-mounted performance

The huge lag with the Stream Rotors was the lack of factory low-drain check valves. In order to provide for LDC, we had to use the Hunter version, which was pricey, needed a deeper hole and the friction loss ate you for lunch! Toro never got it, tho I bitched and moaned to the REPS for years. :hammerhead:

The shrub head has some sort of check valve, I'm told. I'd take that great basket strainer design anyday, tho the cost of a 12" SR w/Hunter LDC was pricey, even for me! Prolly the most expensive combination I ever installed.

I stopped using the shrub heads, because the nozzle assembly was vulnerable to being removed by curious hands of children.

Unless run up a fence line in copper, they also looked like hell.

Have a customer who still has some of these in the yard just going to town. Both full circle heads. They look cool but definitely not 300 cool.

Nope, if you're doing risers (which I like), use copper and either MPs or brass. This is saying they are in the center or rearwards. Front-load risers are a sign of pikerdumb. :hammerhead:

Stream rotors work okay with 3/4-inch sch 80 risers, since the forces are spread out.

Nelson had a stream-rotor knockoff with a feature that allowed you to choose one of several fixed distances based on how the serrated cover piece was aligned against the next piece down.

The client had planned for more dwarf trees, so I spec'd SRs and subbed it out. (anyone notice anything strange?)

Good call, he was the installer and this was my walk-thru. I'd spec'd two f.c. heads and only one went in. He looked at me and said, "what's the big deal, the sprays touch each other at the end of the throw, so I thought I'd save you guys some money.":dizzy:

Almost forgot about that one... the Gearstream... had a combo 1/2" and 3/4" inlet.
