Autoflush valve to eliminate clogging
A low flow rate in the last few pipe lengths of the pivot can cause dirt to build up. The Autoflush valve eliminates the problem of clogged nozzles by flushing the machine every time the pump is started, thereby purging the dirt from the overhang.
1 of 6Highest quality galvanising
Agrico piping is guaranteed to have at least a 100-micron zinc layer, ensuring a piping lifespan 1.4 times as long as pipes galvanised according to regular industry standards.
2 of 6Many tower options
Tower structures are available in low, standard and high clearance, to accommodate all kinds of crops. Our optional windsaver towers have a longer wheelbase for windy areas, and come with a two year warranty against being blown over.
3 of 6Long spans save money
The optimised structure of our spans allows us to cover up to 70 m with a single span. This means fewer towers, fewer wheel tracks, fewer motors, fewer gearboxes and fewer tyres. Less maintenance. Less trouble. Lower cost. Higher yield.
4 of 6Electrical control system
We use only the highest quality branded switchgear. The electrical system is 100 % rust-free to limit corrosion and malfunction of the control system. A control voltage of 230 V (versus 110 V used in US machines) decreases resistive losses in the cable while improving prices and availability of parts in southern Africa.
5 of 6Agrico Web Control
Agrico centre pivots come with a variety of web and electro-mechanical control panel options. Our Agrico Web Control system has the ability to control multiple pumps, vary pump speed and pressure as machines are started or stopped as well as change position.

The Agrico G4 centre pivot
Our fourth-generation centre pivot is the result of three decades of accumulated knowledge and experience.
Designed from the ground up, we have incorporated every lesson learnt over the years to build a highly theft-resistant and sturdy irrigation machine for African conditions.
Features of the Agrico G4 centre pivot
Resistant to theft and vandalism
The G4 centre pivot is designed to safeguard your property against theft. All cables, electrical and drive train components are either hidden or made safe. The span cable is protected within the span pipe and tubular tower legs, and a completely revised compact centre with a secure main panel enclosure prevents vandalism.
Shallow wheel track for less crop damage
The narrow built tower structure with its closely mounted wheels decreases the dead area next to the wheel track by more than 30 %. Less crop damage and dryer wheel tracks provide you with maximum yields and profitability.
Re-designed compact centre and span structure
The evenly loaded G4 structure allows spans of up to 70 m. New features include centre and span joints with a corrosion-free rubber-on-plastic seal for maintenance-free operation, direct metal-on-metal contact between flanges to limit UV damage and much more.
Optimal nozzle spacing
A 2.5 m nozzle spacing allows excellent wetting uniformity and higher yields, even when using low-maintenance static sprinklers. A 5 m spacing option can be selected when modern dynamic sprinklers are used.

The Agrico G3 centre pivot
Widely known for its reliability and versatility, the Agrico G3 centre pivot faithfully serves producers across the continent. Our trusted G3 offers coverage from 2 to 200 hectares and is suitable for standard, high or low clearance irrigation, as well as linear irrigation.
High-stability towers, long spans, extra-thick galvanising, rust-free control systems and Autoflush valves are standard features that distinguish Agrico pivots from the rest.
Features of the Agrico G3 centre pivot
Stable centre structure
Ultra-strong machine structure
Optimised span design
Extra-thick galvanising
Rust-free control system
We use only high-quality, branded electrical switchgear. Rust-free stainless steel main panel enclosure plus rust-free UV-stabilised, fibre-reinforced polyester tower boxes with solid stainless steel control rods ensure ultimate durability. Agrico pivots will not collapse as a result of rusted control rods, or broken age-embrittled plastic cam arms.
Compatible with LEPA
LEPA (Low Energy Precise Application) is an alteration on a center pivot where the sprinklers are placed much closer to the ground. The sprinkler package places water directly at the root zone, greatly reducing evaporation due to strong winds and high temperatures. LEPA sprinklers operate at low pressure to save energy during irrigation. Agrico has fitted around
65 000 spray plates to hundreds of pivot spans over the last years. We have perfected the arrangement of sprinklers in order to reduce the spacing and make LEPA possible.
Agrico’s linear irrigation systems
Linear irrigators move laterally up and down crop fields to provide even, widespread irrigation – optimising water usage, limiting runoff and improving crop yields. Linear irrigators are typically most suitable for fields with a long and rectangular shape, and for situations where land is the limiting factor, not water.
Agrico linear irrigators can be customised to various field sizes and provide a range of benefits for agricultural applications. Our linear irrigation systems utilise industry-leading components and offer many beneficial features.

Frequently asked questions about centre pivots and linear irrigators
How does installing centre pivot and linear irrigation systems work?
In order to design and install the right irrigation system, an agricultural expert needs to survey your fields and have accurate insight into your farming requirements and objectives.
Depending on these outcomes, an expert will recommend the right type of surface irrigation (like drip and micro-irrigation) or overhead irrigation system to match your exact needs.
What are the advantages of centre pivots?
Precise application targeted fertigation and limited surface runoff
Centre pivot irrigation systems distribute optimal volumes of water or nutritional solutions across widespread areas of land. Even application reduces the risk for nutrient losses, and the system may also be used to optimally apply herbicides and pesticides. Centre pivot systems are designed to minimise surface run-off and provide deep percolation when used to farm suitable crops.
Reduced variability
Centre pivot systems are generally 80-95% efficient in application, which is high marks compared to 50-90% for forms of surface irrigation.
Lower labour requirements
Centre pivot irrigation systems can be automated, and even paired with remote control and monitoring capabilities. This allows farmers to optimise systems remotely, and reduce the need for labour to constantly operate the equipment.
What does a centre pivot irrigation system cost?
The cover of a centre pivot irrigation system largely depends on the size of your fields, as the cost per hectare for pivots and components is usually cheaper for larger systems.
Centre pivot irrigation systems are designed based on your farm’s specific requirements and may be associated with other prior preparation processes such as adjustments to your fields’ topographical composition.

What does a linear irrigation system cost?
The cost of a linear irrigation system is usually estimated per hectare based on the size of the farm. Linear irrigation systems are also associated with other costs, including aspects such as land preparation to ensure implementation of the system is viable.
