Sadly no, it only has one speed for each motor, but the way you control application is by adjusting a percentage timer in the panel, which controls the frequency of a minute that the end tower moves (i.e. 50% would be 30 seconds out of a minute that it moves, and 30 seconds it's stopped). Hydraulically-driven pivots continuously move and do have speed control, but this is an electric drive pivot, with 480V 3ph gear motors.
Yep it sure is moving. It has a gearmotor on each tower, between the two wheels on the basebeam, that spins at about 68rpm. That motor drives two gearboxes (one behind each wheel), where it's geared down even more. They typically move about 16 feet/min, which is about an average person's walking speed. That's where they get the term 'walking" a pivot around.
Wow, that brings back memories, some not so good. I worked on my grand dads farm years ago and had to work on his pivot. It was old with impact heads all the way down. I think it was a Gifford-Hill. For some reason flat tires seemed the rule. Nothing like changing one of those monsters in a muddy corn field! Or micro switches that crapped out and shut the whole thing down. I think it had 9 towers and 3 wells to run it. Oh, the good ole days. Thanks for posting. Ben
Oh yeah, I can relate there! Been many a time we've had to change a tire in 2-3' of muck, and several have had a microswitch or two go bad on them in the tower boxes. Most of the time it's the safety one that does it, which breaks the loop and shuts the whole thing down. The worst is when they meet up with a tree...I've got 2 end guns in the garage right now that had that happen. It's always fun when you've got 28 pivots to run! lol
