Kuhn is specialized in sprayers, offering several equipment options. If you intend to perform an efficient spraying, you need to know the Arbo line, featuring tested and approved components to obtain the best performance for your spraying. A machine with modular chassis, various tank capacities - 1000, 1500 and 2000 liters - and blower with different sizes - 800, 840 or 900 mm. It is also possible to choose between two control models: manual or electric.
The entire trailed air-blast sprayer line uses an amplifier box system, which considerably reduces power requirement and, consequently, fuel consumption.

Modularity - the basis of the Arbo line

Modular chassis - Arbo with 800/840 blower

Modular chassis

Developed under a modular concept, the Arbo line chassis is composed of several parts, thus allowing the replacement of individual components, facilitating their maintenance.
The Arbo chassis has two finishing options: Powder coating or hot dip galvanizing. Hot dip galvanizing is a process in which the metal parts receive a zinc coating, exceeding the 100 micron layer, an intense protection against the attack of chemical products, ensuring a significant increase in the useful life of the metallic components. Another important point relating to the chassis are the various adjustments, whether in height or track width, a factor that is important for the diversity of orchards.

Fiber tank

The three tank versions, with a capacity of 1000, 1500 and 2000 liters, are made of fiberglass, a resistant material that allows easy recovery in case of need. They are tanks with a special design that favor working in orchards where there is a large leaf mass, due to the clearance between the trees.
The tank has internal wave breakers that help in the stability of the machine on slopes, as well as increase the resistance of the tank walls.

High resistance components

Diaphragm pump

Diaphragm pump

The parts that make up the diaphragm pump have been carefully designed, with an oil tank built in aluminum and the areas where the chemicals circulate, in brass, ensuring protection against chemical reactions.
The diaphragm pump has stood out a lot from excellent performance in the field, as it works easily with dense liquid and maintains pressure stability due to the precise synchronization of the piston set – it produces high pressures of up to 40 bar – in addition to being self-priming, which eliminates the air from the circuit. This type of pump allows dry work without spray mixture, with no damaging to the repairs. Besides the efficient response, the diaphragm pump is easy to maintain due to the quick and easy access to internal components. Simple and easy.

Spraying control

Thinking of resistance and efficiency in the field, Arbo line offers two control options - manual or electric. Both entirely made of brass, to ensure the high resistance of the set of components.

The manual control can be removed from the machine to be placed on the operational base, thus facilitating access to operations. As for the electric control option, in addition to robustness and resistance, the operator can work with ease and agility, controlling the opening and closing of the sections via an electric panel.
The actuation mechanism of the electric control occurs by means of a solenoid valve, which avoids problems with humidity and drift. It is full-proof resistance!

Nozzle holder

The spraying circuit offers a lot of security, with stainless steel spraying branches and double nozzle holder in brass with anti-drip system. Field safety and environmental safety. The anti-drip system has the important function of leaving the initial spray opening simultaneous and avoiding product losses due to dripping when the section is switched off.
With the double nozzle holder, it is possible to change the spray tip model easily and fast, with a simple turn on the nozzle holder. In addition, the nozzle holder offers the condition of degree adjustment (spray direction) without the need for the use of wrenches. In addition to these points, the nozzle holder of the Arbo line is entirely made of brass, a material with proven corrosion resistance. Long life ensured!

Blower and transmission circuit assembly

Amplifier box - two speeds

Amplifier box

Arbo line is a complete and robust machine, offering technology, safety and economy in the field. The transmission circuit is composed of a wide angle drive, to facilitate maneuvers at the end of the lines and an amplifier box for two different blower speeds. An equipment with an exclusive system and no belts!

The drive relieves the tractor's effort and offers two working speeds. The choice is at the discretion of the customer's need to obtain more or less ventilation. To avoid efforts and damage to the system, there is a clutch assembly between the transmission and the blower that reduces the initial drive torque, considerably reducing maintenance costs, as well as reducing fuel consumption by more than 10%.

800 and 840 mm blowers

Fruit growing works in different tree architectures, so Arbo line offers different blower sizes.
The models featuring 800 or 840 mm blowers have excellent ventilation and speed, reaching 100 kph or more, which facilitates the propulsion of the drop to the target and the opening of the leaf mass. A simple and compact blower, of low cost for efficient results in the field.
The Arbo line can be used for a range of crops, since it has variations in wind through the transmission. Possible height settings on wheels or auxiliary deflectors offer many adjustment options for more effective and accurate work.

900 mm turbine

Including the line of specialized machines for use in fruit growing, Arbo machines can be equipped with a 900 mm turbine, generating an excellent volume of wind due to the double air outlet. The 900 mm turbine has two propellers. A fixed one, which divides the air inlet, and a movable one, which captures the wind and propels it in all directions.
This turbine model is the only one in the market that provides uniform ventilation on both sides of the turbine, in addition to creating a swirling effect due to the position of the propellers, thus facilitating the coverage of the target inside the plant. The aluminum propeller blades have adjustment options in three angles, ensuring a varied wind volume from 30,000 to 70,000 m³/h.
