ga.prime - no, I haven't, unless the occasional very short person in town is one... can't see their feet usually.
jrn, I'd need to go look see if the brand name is on it, it's an ecostream or some fancy modern thing like that. It's very good, best effluent irrigator I've worked with so far but that might just be because it's only a couple of years old, not thirty or fifty. Had trouble once when the 'stop' lever got bent and hence failed to stop it, so I keep an eye on that... not sure how it happened.
being a good operator simply increases the chances that the owner of your lease block will call it a good farm and sell it for way more than it's worth.
