CA Lessons: Landscaping To Reduce Wildfire Risk
While there are no ways to fireproof a property, there are strategies to design and maintain landscapes for reduced vulnerability. Click here to learn more.
Last one I saw like that was about seven years ago when we yanked the last one out of one of our older systems. It's similar to the Rain-O-Mat ball driven head but I don't believe this is a ROM. The ones I remember have a huge brass body on them also. Very heavy!
Couldn't say for sure. I know we pulled out a lot of Rain-O-Mat heads in the past when we were upgrading systems. They looked similar but I believe they were ball driven. Heck, can't even remember if the Rain-O-Mats even had the center spray on them since it's been so long and they were torn down and taken to the recyclers many moons ago. Our original upgrade was to swing joints with Toro 640s that are now being replaced by Hunter I-40s as they go out.
The Toro 640 is a very good large field rotor. One problem they have (besides the stator/nozzle matching requirement and the fixed arc motors) is that they don't pop as high as most of the newer field rotors. They then become susceptible to sticking in the "up" position and then being sheared off by a mower or they stop turning.
Here's a 640 I replaced just the other day on a baseball field.
