Thanks to the advice of everyone here on this forum, I swapped all of my Nelson 6000 heads to the MP3000's. While it hasn't been super hot and dry around here I truly believe they have much more uniform and better coverage for my particular application. Please check out the pics and let me know what you think. I'm really pleased so far.

Great!! Hope it works out for you. I haven't had the best luck with those, but I was tring to fix a pretty bad system and it just didn't work.

They appear to be working wonderfully so far. The problem with my system was poor pressure and poor head to head coverage . The 6000's just weren't cutting it. I have these set at full distance and I get at least 70% into the stream of the opposing head. A lot of them though reach the adjacent head. I'm hoping this works or I give up :-)

those look like Toro 300 series rotors....

Koster, they are similar but a bit different from what I understand. I have no first hand experience with the Toro's though.

They are only similar to the Toro 300 series in looks only - that is the multi-stream pattern looks similar. In design, reliability, gpm, etc., they are worlds appart.

Jim, could you elaborate? Which are better, worse GPM rate, reliability etc??

Thanks,

Well, I've always liked the look of multi-stream rotors. And from what I gather, most people do. So I used to mess around with the Toro 300s a lot several years ago.

I installed them in the lawn in my old house - mostly for show. I wanted an irrigation system that stood out and drew people's attention to it. And for that purpose, it worked. That gave me 3 years of experience working with those heads. And now, even though I've moved, we still maintain the property and the irrigation system.

Any time we've installed a system using the Toro 300s, we've always experienced challenges. Nothing all that big. But more challenges than we're used to. The heads get clogged easily. The little discs on the top of them quit working occasionally, etc. We are always having to fix or replace 2-3 heads every year.

We've done a lot of irrigation repair work on systems that had the Toro 300s too. Recently, we did one where almost every head on 3 zones needed work. They just don't last as long as say a hunter PGP or other single streem rotors do.

The GPM usage on the MP Rotators is also much lower than the Toros. You have to run the MP Rotators 2-3 times as long to get the same amount of water. But the nice thing is the MP Rotators have near perfect precip. rate. And the amount of minutes you have to water really isn't all that imporant. They are ideal for low pressure, low flow conditions.

So far, we haven't had any problems with the MP Rotators. We've been installing them fairly regularly since last spring. But I don't have as long of a history with them, since they are new. But so far, they are very reliable.

There are more differences too. Spacing, etc.

Jim, can you elaborate on how you space the MP's? How long does one typically need to water to achieve adequate precip.? I have 40psi while my system is running and I usually irrigate 45 minutes per zone. My System consists entirely of the MP3000's though because I need the distance.

Thanks for taking the itme.

Joe,

To calculate your preciprate use the following formula....


GPM (one Full Circle) x 96.25
--------------------------------------- = in/hr
Head Spacing x Row Spacing

With any stream rotor, gear drive and impact rotor, head spacing at head to head tends to give more even coverage.

Space them properly and you should get good coverage.

I really like 300's and use them allot. You just have to make sure the lines are flushed of all debris before installing the head. We have many 300's that have been in for 10 to 15 years with no problems.

Ive put a lot of MP's in to replace spray heads with out enough pressure, and as new systems, never had any problems, I like the fact you can mix them with standard gear drives.
take a look at the site www.mprotator.com

Well whatdaya know... I've had some applications where I've had to use Toro 300's, and I even use some at my own place where they're used to water the plants on my waterfall berm, but for sure they're not my first choice. Like some of you, they tend to have problems - ongoing problems. I have one maintenance account, a ranch, that has a lot of 300s around, and all I can say is that I should be charging by the hour. Perhaps its the dirty water.

Never heard of the mp rotator. I bet the mp rotators are non existant in this area. The info on them looks interesting, but see that if you're trying to water a pattern of 315 degrees without going the full circle route you'll be outa luck. Seems like they need to refine their three models and make them adjustable to more standard degrees. Perhaps no biggie, eh?

I didn't see, but do these have a 3/4 or 1/2" base on them?

1/2 base, comes in male or female
