Yea, that's what it means. Can you adjust a Safe-T-Lawn or just let it do a 360?

the adjusting device on Nelson gear drive rotors was a direct swipe from the (more reliable) Safe-T-Lawn original, and it worked the same way. Set the arms to get your arc of coverage, and flip over the device to make it a full-circle. Safe-T-Lawn also had a deluxe version of the device that gave the head the same break-out/snap-back clutch action the R-50 copied.

That means all the R-50's will eventually fail to retract, and the Sprinkler Head Marathon award goes to the Safe-T-Lawn ball-drive-rotor.
well it just takes 20 years... that's ok with me

Good grief, it took forever to fine tune a Nelson rotor. It was faster to change out a whole zone than adjust one of them.

You could free-wheel the STL rotor, though, so less worries there.

Agreed. Serious PITA.

poor Toro TR-50 has lots of great bells and whistles, but not being able to free-wheel it is going to be the deal-killer

who here likes toro s700 series rotors? I have to say, when properly designed, systems using those do a pretty good job, but really my impression is they last for a very long time. I have a ton of them in systems that are 30 yo and not skipping a beat. I have started to replace now, with rainbird 5000 on those systems as i dont carry toro. The only toro used here is the s700, so no use in stocking any toro. seems the spray heads at least of yesteryear from toro are the worst ever at staying stuck up and run over with mowers.
