Pivot track in Peanuts
This picture shows the circular wheel track of a center
pivot in a peanut field. Screven County, GA. USA. Center
pivots are the main method of irrigation in GA. The state
has somewhere between 8000 and 9000 such systems.
Re: Pivot track in Peanuts
This picture shows a potential problem with center pivots.
The wheel tracks can serve as seed points for erosion as
water runs down them and washes out areas in fields. Not too
common in this part of the country but always worth
Re: Pivot track in Peanuts
Another close up shot showing how the pivot tires can dig
ruts in soft, wet soil.
Re: Pivot track in Peanuts
Those ruts must be 8 feet deep!!!

Sorry, couldn't resist it. Why does the system not through
the water behind itself when it's working? Then the ground
it's running on would be dryer!
Re: Pivot track in Peanuts
Yes, these ruts are not too bad. Although for this area they
are pretty severe.

There is a whole science as to how water is applied from
these overhead sprinklers to (in no particular order):

a. reduce evaporation losses
b. enhance inflitration
c. limit surface crusting
d. optimize uniformity
e. reduce costs

Factors that can be manipulated include water pressure,
droplet size, application pattern, and height of

There are pivot attachments known as "boom backs" which do
exactly what you suggest at each of the pivot towers (where
the wheels are). ie., the sprinklers at the wheels are
extended back behind the direction of movement so that the
pivot is always walking on dry ground. It's an extra layer
of cost and complexity and I have not seen this used locally
but I can see the benefit (also for reducing compaction).

Re: Pivot track in Peanuts
Those aren't real bad yet!
We have 15 pivots and a 1/2 mile linear, with corn, beans
and alfalfa as our crops. I have been looking at a better
solution to this problem. There are a whole load of
variables involved and one tire or wheel will not solve all
the problems, nor any single thing.
Boombacks are a good alternative if you operate your pivots
in one direction. If you equip them with booms on both sides
of the pivot for both directions it becomes kind of pricey.

There are other wheels out there but they are also pricey.
Here is a picture of one machine we have that has different
wheels on towers 2 thru 6.

I am impressed with one "wheel" alternative, but cost is an
issue. Longevity is another issue.
Re: Pivot track in Peanuts
By putting "wheels" in inverted comma's are you saying you
have had good experiences with a tracked system like:

Of those that you have tested, what is your favorite wheel
Re: Pivot track in Peanuts
Yes, sort of.

These are on one tower of the machine previously posted.
I will have to check my records but I think this was last
summer after the pivot made 6 applications of water @ 1.30"
on alfalfa, where the picture was taken at.

But I will not say they are the best at everything. They
are closer getting to a solution.
Driving across the tracks in even the alfalfa you don't feel
the track.
The price is $1200 per tower and you have to use bias recap
irrigation tires with these. So the $1200 is additional per
tower. Plus you need to fill your tracks in first before
operating these. They will not take care of a problem that
is there in the mid season.
The weak link in these may be the bushing that is at the
connection point of the plates. They have hardened them up.

We also purchased a track filling unit to fill tracks, since
we predominately no-till. Spring or Fall, not sure which is
better yet.

Nebraska has over 50,000 center pivot irrigation systems,
and all 4 major manufactures of pivot are here
also. FYI
Re: Pivot track in Peanuts
Big tires (11.2 x 38) make one big difference! Another big
thing that works is triple tires. I'll see if I can make a
pic of one of those. We grow potatoes and the land is pretty
soft here, and we apply 15-18" water at 0,75" per pass, so
after 20 passes or so, my pivots still are not stuck!
Re: Pivot track in Peanuts
I'd like to see a pic of that triple tire arrangment if you
can get it...
