How much does a Reinke pivot cost?
Initial Cost • Pivots typically cost between
$245-$400/acre
($600- $1000/ha).
How many acres does a pivot cover?
Center pivots are typically less than 500 meters (1,600 ft) in length (circle radius) with the most common size being the standard 400-meter (1⁄4 mi) machine, which covers about 50 hectares (
125 acres
) of land.
How much is a pivot in South Africa?
Pivots typically cost
between US$584 and US$993 per hectare
. The bigger the system, the cheaper it gets per hectare. The 50 000 emitters on a 50 ha drip system requires considerably more dedicated management than centre pivots.
How much does a 40 acre pivot cost?
40 acre Center Pivot System Example. Standard 40 acre system with end gun, installed at a cost of
$38,000
with a well and power source cost of $30,000.
How much land can a center pivot spray irrigation system irrigate?
Center pivots are available to irrigate from 5 to 500 ac (2 to 200 ha) although a typical machine will generally irrigate about
125 to 130 acres (50-52 ha)
. Economic considerations usually limits their application to irrigated areas larger than 50 ac (20 ha).
How much does a Valley Center Pivot cost?
Standard 160 acre system and end gun with actual irrigated area of 132 acres installed at a cost of
$48,000
with a power and water source and connecting equipment cost of $30,000.
How much electricity does a center pivot use?

How long is a pivot section?
The length of the span can vary
between 130 and 200 feet
. The typical pipe on the pivot has an outside diameter of 6
5
/
8
inches with a wall thickness of 0.109 inches. The pipe and the towers are typically galvanized to prevent corrosion.
How many gallons of water does a pivot use?
This example shows the minimum water supply rate for a center pivot equipped with high pressure impact sprinklers should be approximately
772 gallons per minute
(656/0.85). The minimum system flow rate for a center pivot with low pressure spray nozzles at truss rod height would be 690 gpm (656/0.95).
How much water does a pivot need?
Most center pivots are designed to be capable of applying 0.3 inches over 24 hours at 6 gpm/ac, meaning you could potentially apply just over 2 inches in a week.
Two inches per week or 9 inches in a month
is more than enough water to meet a crop’s water use requirements in the humid East.
How do you calculate acres in circles?
The formula for the area of a circle is: Area = π * radius2. If the radius is given in feet, the area is in square feet. To convert from square feet to acres, divide by 43560. So the acreage of a circular area is:
Acres = π * radius_in_feet2 / 43560
.
How does the pivot sprayer work?
As the name suggests, center pivots
irrigate in a circular pattern around a central pivot point
. Pivots are capable of applying water, fertilizer, chemicals, and herbicides. This versatility can improve the efficiency of irrigation practices by using a single piece of machinery to perform several functions.
How does linear irrigation work?
Linear irrigation machines
travel back and forth across your field instead of around a central point as a center pivot does
. A linear can move in a straight line, in forward or reverse.
Where are Reinke pivots made?
We’re still in
Deshler, Nebraska
, the original location established by founder Richard Reinke in 1954. We choose to remain in Deshler – America’s heartland – close to our roots and our customers because that’s who we are.
How efficient is pivot irrigation?
It can easily manage water levels in the soil due to the semi-automatic operation of center pivots and its lateral moves. Water application efficiency ranges
up to 80%
, depending on management and designed installation in the field.
Where is center pivot irrigation used in the US?
The state of Nebraska
is largest producer of center pivots in the world, and the largest irrigator in the United States. In the early days of irrigation, very little water conservation equipment or technology was available and large amounts of water were lost to evaporation or runoff.
Why are farms circles?
The circular pattern, however, is different from the regular patchwork many people imagine traditional farm fields to be.
The shape is the result of the center pivot irrigation
, a development of the post-World War II era that profoundly changed the course of American food production.
Is center pivot irrigation expensive?
When it comes to initial investment costs,
center pivots are much less expensive than drip irrigation
– more than $600 per acre less ($1,700 per hectare less). On average, pivots also last longer – 25 years or longer is normal for Valley
®
equipment.
What does it cost to irrigate an acre?
Small systems which are operated by manual labor and gravity flow can cost as little as $50 and irrigate a small garden. Larger systems requiring pumps and permanent piping can cost from
$1800 to $2500
an acre. All irrigation systems will cost you time to operate and manage.
What type of irrigation loses the most water to evaporation?
Sprinklers, drip irrigation, hoses and watering cans are the most common irrigation methods in home gardens and yards.
Sprinklers usually lose the most water to evaporation
because they spray water through the air and over a wide area, but other factors also affect evaporation rates.
