NWIN | i was wandering what the longest center pivot irrigation that anyone has seen |
|
| |
|
ne colorado | 19 tower covers pretty much a section 2 of them with in 5 or 6 miles |
|
| |
|
Northeast Louisiana | Half mile span in my neighborhood. |
|
| |
|
Blackton AR | I know of several 1/2 mile pivots. I was told there was a pivot that was 3/4 mile long, but I don't know that for sure. Friend of my dad's worked the farm for a guy, but I never saw the pivot. |
|
| |
|
Lorenzo, tx | I know there is a mile long one just a few miles north of here. Im almost positive its a mile long |
|
| |
|
SW KS | Holy smokes! That's like 2000 acres under 1 pivot. It'd take some water to pressure that baby up. I can just imagine..."Walk in there and replace the gearbox on the 20th tower" |
|
| |
|
Sw Mo | Some mile longs right outside Dumas and dalhart tx I'm pretty sure |
|
| |
|
Athens, Ga | there is a half mile pivot 5 miles from me. over 500 ac under it. it has 2 - 16 in wells feeding it |
|
| |
|
SW KS, near Dodge City | If they were there, they're not anymore. Or they hid them from google maps really well. I'm guessing they were just 1/2 milers. |
|
| |
|
Clymer, NY | There are ones in Saudi Arabia that up to 3km(1.86miles) long. tried finding it on google earth but no luck yet |
|
| |
|
Whiskey, Tango, Foxtrot | Theres a 20 span north of here. Only a 1/2 wiper. |
|
| |
|
| That's where experiance come into play. Take one of the new guys with you. Tell him "If you carry the new gearbox in, then I will carry the old one out.'' They say ''sounds good to me,'' thinking that after they get all sweaty and dirty changing gear boxes in a corn field in July, the last thing they want to do is carry anything back out. Then they usually thank me for for being such a nice guy. So we trudge in, change the gearbox, and I proceed to hang the old box on the tower. The new guy says ''what are doing?" ''Well, I am going to hang this gearbox hear, and when the pivot comes around to the pivot road, I am going run out there with the 4 wheeler and grab it.''

Brazilton KS | The longest I have found any mention of are half that length. I think you are confusing diameter with length. |
|
| |
|
Bow Island, Alberta | There's a few section machines in my neighbourhood that have a corner system. They would be about 2600 feet plus another 287' for the corner. With an end gun, I think they cover close to 600 acres out of 640. |
|
| |
|
Northeast Louisiana | We have a 3200' pivot that makes a full circle and a 3400' one that makes just over a half circle. |
|
| |
|
Athens, Ga | what do you have supplying water to it. |
|
| |
|
Dalhart Texas | Longest around Dalhart Dumas area is probably 590 acres. It's about 8 miles east and about 8 miles south. Problem being with any 600 acre pivot or 3200 foot (738 acres) is enough water thru it. 700 acres you would need 3500 gal. So every span would have to be 10" pipe probably and even on level ground you would need 60 psi at least at the pivot just to get 15 psi at the end. There is no such the as a mile long pivot. I'd bet on that. The 3200 and 3400 long is by far the longest I have heard of. I have been told of a 650 acre pivot north of Perryton but have never seen it. A lot of half milers went up because they were cheaper short term in development costs. Long term they are not the way to go. (we have several) They get stuck easier, wear parts out faster and are harder to manage your water application. Just my opinion. |

South Central Nebraska | I just drive in with 4 wheeler or UTV, now. I run the numbers on how much corn I run down, worth every penny for it to carry in tools, tires, gear boxes, rock or whatever else you may need. |
|
| |
|
Columbia Basin, Ephrata, WA | You actually go get the gearbox? Around here they sometimes get removed after harvest. Sometimes they ride around for a decade or so.
My dad bought a Honda tracked wheelbarrow thing that we use for gearboxes and flat tires. I'd hate to go without it.
|
|
| |
|
Fairbury, NE (Southeast) | +1 for one row worth i do it. |
|
| |
|
Pasco WA. | Ben Where did you find that Honda? I would like to have one.
I also leave the gearbox's hanging on the tower untill after harvest. Sometimes we even tie the falt tires on.
Pretty hard to find a pivot much longer than 1/4 mile here. The big pivots can't apply enough water.

East Prairie, MO | My personal longest pivot is 1800 feet, 11 tower Reinke. Has just under 300 acres under it, but there is a full section half miler right across the road from it. I hang the old gearboxes to the tower legs also, I finally broke down and took a few off this winter that had been riding for a few years LOL. Flat tires are the latest thing I started hanging, easy to roll that spare in but that wobbly flat that's broke down off the rim is hard to roll in a muddy wheel track! For the hard to reach areas my spray rig sees pivot repair duty a lot, throw a gearbox up on the catwalk along with a handyman and 1/2 cordless impact and get after it. |

| Correct the diameter of the largest ones in SA is 3 km, so almost a mile long... |
|
| |
|
Central Texas Panhandle | There is a 24 tower Valley right on the Interstate just east of here. Windshield wiper. When it was put up it was the 3rd longest in the world, but that has been 20 years ago. |
|
| |
|
Northeast Louisiana | A 16" turbine well, probably about 2200 gpm. |
|

|
Northeast Louisiana | In our area, irrigation is supplemental, although the past 2 summers have made me wonder. These big pivots can put out about .6" every 5 days or so, so it wouldn't keep up in areas that rely heavily on irrigation. In our case though it is enough to help a lot most years. Cost per acre gets pretty reasonable when you can go that big, but not many places have an unobstructed 6400' circle. |
|
| |
|
Dalhart Texas | 1.15 square miles or 741 wet acres I think. I asked a couple of Valley guys and 1746 acres or 3k diameter is "impossible" |
|
| |
|
| Not quite 3 km, but close enough at 2.6... see 4th page http://www.zimmatic.com/downloads/Lindsay_IA_Winter09__FullBook_Web0610.pdf |

|
Dalhart Texas | nozzled at 2233 gpm if i did the math correct. so its supplemental irrigation. I would love to see that pivot in action. If you had a "Dual Span Pivot" I guess you could have a long one like that and have full irrigation desert style. |

NC Nebraska | +2 we just drive in on 4 wheelers |

Columbia Basin, Ephrata, WA | The Honda was bought new back in the mid-nineties. I'm pretty sure they stopped making them not long after that. There is a company making something similar. They even have a model with an onboard generator, which I thought was great for running an impact wrench until I found out how good cordless impacts are now.
