We have a couple valleys that were installed in 70 and 71. Changed over from steel wheels around 80. Renozzled them again in the last few years and really helped, they were shot again. Change a few gearboxes and motors every summer on each one, but they still work pretty well. The pipe is all in really good shape except the necks started leaking where the wiring runs through. Thinking we might just get that part and keep running them. We put 5 boots on between the 2 earlier this year and I am just amazed how good the pipe is. Not like the pictures I see of a lot of pivots under half the age of these. They are both on deep wells so the water must be different than other places.

We're still using a Valley Little Fielder to water an odd shaped corner the longer system misses. Landowner got it in the early to mid 70's.It watered 9 acres in a turn, then you moved it to another riser. I spent more time watering 7 acres than Dad did watering 160. The piston drive was replaced in 2007 with a spinner drive.

How do you move it?
The last standing Valley waterdrive around here was scrapped in the last year, but it had not run in some time. There are a couple of other small waterdrives, but I don't know what brand. They look like a Walking 40, but I don't know if they did waterdrives. I know where there is an Olson machine, but it's been converted to electric.
We have some surviving Zimmatic spans that are supposed to be from 1967, and a small Pierce machine that is probably nearly that old. We had a lot of painted pipe Gifford-Hills running until 2006. There got to be a lot of holes in those pipes, but the G-H spans were still very solid and they had the clearance to run in tall corn.
A lot of the brands from the 70's are disappearing fast. Along with G-H, there aren't many Hygromatic, Sargent, Pringle, Sparkle, Rain-Cat, or even Pierce or Tumac machines left.
