What are agricultural crop sprayers?
Agricultural sprayers are designed to apply crop protection products and liquid fertilizers. These applications make them highly versatile for use on field crops.
What are the components of a crop sprayer?
A sprayer is an indispensable tool for plant protection. It is composed of several essential components, all held together by the chassis. Key components include:
- A tank for storing and transporting liquids.
- A pump (centrifugal or piston membrane) to move the liquids.
- A spray boom for uniform application of liquid on the field.
- A regulation system to provide the desired amount of product.
- Different precision application systems to optimise the functions of the sprayer.
All these components work together to ensure the sprayer performs as intended.
What are the types of sprayers?
There are three main types of agricultural sprayers available on the market: mounted sprayers, trailed sprayers and self-propelled sprayers. KUHN have designed and built a diverse range of sprayers to meet your requirements.
Mounted sprayer
Mounted sprayers are directly attached to the tractor hitch. KUHN's mounted sprayer range caters to different types of farms, offering a wide range of machinery, from basic to premium crop spraying models.
Advantages of mounted sprayers
Mounted sprayers provide excellent stability on sloping fields and exceptional maneuverability at field ends, making them ideal for small fields. Moreover, these sprayers can accommodate a front tank to increase spray solution capacity, making them more versatile.
Trailed sprayer
Our range of Trailed sprayers are best for medium to large-scale farms that require higher work rates. Designed and built for mixed crop and livestock farms, cereal farms, as well as contractors, these machines are attached to the tractor using a drawbar and are towed during operations.
Advantages of trailed sprayers
Trailed sprayers are better suited for wider working widths and can accommodate tanks with larger capacities. Additionally, the presence of an axle and tyres ensures improved weight distribution on the ground, reducing soil compaction.
Front sprayer
The KUHN front sprayer is a comprehensive machine positioned at the front of the tractor, capable of carrying clean water or crop protection products. It has its own pump and rinsing circuit. The front sprayer can be coupled with a mounted sprayer to add capacity or integrated with a precision seed drill or tillage machine using a spray regulation kit.
Advantages of front sprayers
Front sprayers offer several advantages that make them a preferred choice in agriculture. One key advantage is that they provide larger water or spray solution capacities. Attaching a front tank also brings improved balance to the tractor-machine assembly and enhances versatility in the field, as a single front sprayer can be used on various machines and for different tasks.
Sprayer tank
The sprayer tank plays a central role as it holds the product to be sprayed. It is a crucial component during the preparation, agitation and rinsing stages. It is important to choose the right tank for your needs, taking into account factors like capacity and material.
Choosing the tank capacity
When selecting the tank capacity, it is essential to align it with your specific needs, particularly considering the size of your farm and your farming practices. KUHN offers a range of capacities:
- 600 to 1,200 litres for OPTIS and OMNIS mounted sprayers,
- 1,000 to 2,000 litres for DELTIS 2 and ALTIS 2 mounted sprayers,
- 2,400 to 4,100 litres for LEXIS and METRIS 2 trailed sprayers,
- 1,000 to 1,500 litres for front sprayers.
Tank rinsing
Proper rinsing of the sprayer tank is crucial at the end of spraying operations to ensure optimal cleaning and to deal with residual volumes. A separate rinsing tank containing clean water is utilised for the dilution and cleaning phases.
Different sprayer boom solutions
The sprayer boom is a vital component for accurately applying products or fertilisers to crops. It consists of stainless steel pipes through which the high-pressure spray solution flows, along with a series of nozzles and a regulation system. Various widths and configurations of sprayer booms are available to cater to the specific requirements of each farm. Boom design is very important: the height of the boom must be adjustable to adapt to different crops and sloping fields.
Hydraulic or manual folding booms
Sprayer booms can feature either hydraulic or manual folding and unfolding mechanisms. Hydraulic booms offer the advantage of effortless deployment and folding, facilitated by a hydraulic system that controls the opening and closing process. This time-saving feature enhances farmers' productivity. Some sprayers, such as the OPTIS, can be equipped with manually folding booms.
Steel and aluminium booms
Sprayer booms are commonly constructed using either steel or aluminium. Each material has its advantages: steel provides robustness, while aluminium offers lightweight properties. KUHN employs a proven painting process that ensures steel booms possess excellent anti-corrosive qualities. The METRIS 2 can be equipped with a hybrid boom, featuring one sturdy steel arm for optimal rigidity and additional lightweight aluminium arms for wider coverage.
How to choose the right spray nozzles?
Nozzles are crucial components of sprayers and have evolved from simple droplet devices to invaluable tools for precision spraying. With advancements in technology, a wide range of nozzles are now available to meet various crop treatment needs, such as reducing application quantities, minimising drift and enabling high-speed operations.
What are the functions of nozzles?
Nozzles are used to spray precise amounts of products in the form of droplets, ensuring thorough coverage of the target area. Choosing the right nozzles and maintaining them properly is essential to maximise application precision while minimising the risk of blocking.
Types of nozzles
A comprehensive range of nozzles are available on the market. The choice of material is an important differentiating factor, with options including plastic, stainless steel and ceramic, each having its own advantages and disadvantages. The four main categories of nozzles are as follows:
- Standard flat fan nozzles, forming very fine droplets that are prone to drift.
- Low-drift nozzles, producing larger droplets that are less prone to drift.
- Air induction nozzles, which introduce air through a venturi effect, enriching the spray with air and forming larger droplets that are less prone to drift.
- Nozzles designed for liquid fertiliser application, capable of forming 3 to 7 product streams.
Nozzle selection depends on key factors such as working speed and application rate per hectare.
