A Compact and Robust Sprayer

A compact sprayer in all aspects

A stable and manoeuvrable sprayer

With a hitch-to-axle length of 4.40 m and height of 3.40 m (with 36 m boom), the METRIS 2 sprayer is an extremely compact machine.
The machine's short length allows for agile manoeuvres at the headland, this improves tracking and limits crop damage. This design also makes it easier to enter fields and reverse into field corners.

The tank's shape is specifically designed to integrate the boom into the overall dimensions and also to limit the overall height when the boom is folded. The 3-arm booms, LEA3, RHA3S and RHA3, are integrated within the machine's outline, and cannot come into contact with the tractor cab. The low height of the METRIS 2 trailed sprayer makes it more stable during transport, ensuring you can drive on the road in comfort and safety.

Strathane drawbar suspension

Good machine stability while you work is essential to keep the boom as close as possible to the target.
The machine's stability is an important factor in achieving this goal. The METRIS 2, with its four levels of suspension, allows you to keep your machine stable and perfectly suspended on the road and in the field.

The suspended drawbar protects the tractor and its driver from any machine movements. During transport with the boom folded, all the movements are absorbed.

Strathane axle suspension

The axle suspended by Strathane shock absorbers, protects the machine on uneven terrain while in the field and on the road. A suspended axle means a longer service life for the machine!
The machine's overall stability while in work also makes it possible to keep the boom as close to the target as possible, by smoothing out the initial irregularities in the terrain. A stable boom starts with good axle suspension!

STRATHANE SUSPENSION: DAMPING AND STABILITY
The drawbar and axle suspension on the METRIS 2 sprayer is designed with ultra-reactive Strathane pads.
Strathane is used to ensure:
  • Rapid shock absorption, without any rebound effects. Strathane absorbs energy without transferring it back!
  • Instant adaptation to the load. Whether the machine is full or empty, the pads adapt their damping capacity to prevent any loss of efficiency.
  • Low displacement, to keep the machine perfectly stable. One pad on each side to guarantee sprayer stability.

Simply intelligent tank design

Efficient tank design
The main tank on the METRIS 2 sprayer was designed to achieve a low centre of gravity. The largest part of the tank is within the frame, providing maximum machine stability.
The deep sump allows for the tank to be drained regardless of the slope in the field. Located near the sump, the four-dimensional mixing system guarantees a homogeneous spray mixture, without the formation of foam, throughout the spraying process.

Maintain balance
The central position of the 450-litre rinsing tank on the axle allows the METRIS 2 to maintain good balance in any conditions. The centre of gravity of the machine remains along the centre axis, regardless of the tank level.
The METRIS 2 sprayer is also exceptionally easy to use. Filling of the rinsing tank? Rinsing tank gauge? All the operations are made from the operating panel.

Injection-moulded polyester tank

The design of the METRIS 2's injection-moulded polyester tank offers a top-of-the-range solution. No compromise on the cost of materials has been made, to provide you with a stable and functional machine.

SMOOTH SURFACE
The new 3,200 and 4,100-litre injection-moulded polyester tanks provide a perfectly smooth surface, both inside and out. As the surface is non-porous, any active product is easily rinsed away to facilitate machine cleaning operations.
Ideally positioned to prevent any deposits from forming, the machine is easily cleaned using three rotary cleaners. Whether activated from the operating panel or from inside the cab, tank rinsing is simple and efficient.

BAFFLE
The injection-moulded polyester tank incorporates baffles to stabilise the spray mixture during transport. The sloshing of water is immediately stopped as to not disrupt the sprayer's balance.

Lightweight and rugged boom

Lightweight and durable aluminium booms

Aluminium booms: A lightweight and durable solution

The booms are made of aluminium which features a density that's almost three times less than steel, keeping the structure light and providing a structure to protect the sprayer components. The lightweight booms allow the sprayer to carry on working even over wet areas.
Aluminium booms feature outstanding durability. Completely insensitive to corrosion and chemical aggression, aluminium needs no special protection and greatly facilitates sprayer maintenance while providing long service life.

KUHN has been using aluminium since 1986 to manufacture booms longer than 18 m because it naturally features several advantages.
  • Natural resistance to corrosion: which is a crucial issue when in contact with plant protection products and fertilisers.
  • Density 2.7 x less than steel: a stronger and lighter boom!

EQUILIBRA suspension

The EQUILIBRA suspension with pendulum linkage provides the boom with a three-dimensional shock absorption system. The EQUILIBRA suspension system allows the boom to remain perfectly parallel to the ground when driving over rough terrain. The boom runs smoothly over the ground and crops and no longer shifts or drifts!

On uneven terrain, the pendulum link offers sufficient freedom of movement to keep the boom steady, regardless of the type of terrain encountered. Two shock absorbers also dampen and limit vertical movements to keep the boom perfectly level, especially when cornering and even at high speed.
The EQUILIBRA suspension is designed to work in intensive conditions and includes as standard an independent anti-whiplash system protecting the boom while cornering or during acceleration/braking.

EQUILIBRA 3D SUSPENSION: FOR INTENSIVE CONDITIONS!
  • Robust pendulum movement
  • Link rods for radial movement
  • Shock absorbers to eliminate any rebounds
  • Independent left/right anti-whiplash system
  • Spring-loaded automatic tilt corrector
  • Frame locking

LEA3 boom

The robust LEA3 boom is equipped with the EQUILIBRA suspension system and is designed to last. Available in widths from 27 to 33 metres, it offers numerous advantages:
  • COMPACT FOLDING FOR TRANSPORT
    The boom folds into three parts, allowing it to be integrated within the machine's outline. Driving on the road is thus easier, faster and safer. Once in the field, unfolding operations are fully synchronised to maintain the sprayer in an excellent state of balance.
  • HIGH-END DESIGN FOR PRECISION SPRAYING
    The design of the LEA3 boom was particularly adapted for precision spraying equipment. The boom can be equipped with the CCE or MULTISPRAY spraying systems, drop pipe systems and with 25 or 50 cm nozzle spacings. The spraying equipment is protected in all directions along the entire length of the boom by the boom's structure.
  • ALUMINIUM STRUCTURE
    The structure of the LEA3 aluminium boom features a lightweight design, as well as strength and corrosion-resistance.

BOOM ASSIST

BOOM ASSIST keeps the boom in the correct position regardless of field topology, automatically adjusting the height, tilt (SLANT) and independent variable geometries (TOTAL / TOTAL PRO). Keeping a boom at the ideal height optimises spray distribution and particularly reduces losses due to wind drift and evaporation.
Using ultrasonic sensors, the BOOM ASSIST system keeps the boom at the correct height above the target regardless of the conditions: day and night, clear or foggy, on vegetation or bare ground. The patented hybrid mode allows the system to permanently analyse crop height to adapt the boom movements.
There thus no need to worry about the boom, the sprayer manages it automatically.

High level of precision spraying

CCE electric nozzle holder

CCE, continuous circulation - electric

Are your fields all different shapes and sizes? The CCE system can adapt to all situations

To limit overlapping at the ends of the field, it is important to understand that the more sections you have on the machine, the more you can reduce overlapping.
So KUHN naturally offers systems with individual nozzle shutoff to optimise coverage.
The CCE, Continuous Circulation - Electric, allows each of the nozzles to be controlled independently by GPS. Nozzles are thus controlled with surgical precision to limit overlapping as much as possible.

The CCE also uses the well-known strong-points of the CCP Continuous Circulation - Pneumatic system:
  • Instant priming of the boom with the spraying mix
  • Instant opening and closing of the spraying system to make the most of section control
  • The entire volume can be diluted = 0 dead volume on the sprayer

MULTISPRAY

The size of the droplet generated by the nozzle is the most important point to ensure good spray quality.
On most sprayers, the greater your forward speed, the higher the spray pressure. However, if the nozzle is not changed, the size of the droplet gets smaller, which increases the risk of drift.
With KUHN's MULTISPRAY precision system, you can automatically change the nozzle according to your forward speed to ensure optimal spray quality. The MULTISPRAY system continuously calculates which nozzle or combination of nozzles is best suited to the conditions based on the desired dose and the speed.

In order to have full precision potential, the 2 nozzles can be activated individually. This ensures quality spraying!
The MULTISPRAY system integrates CCE circulation as standard with nozzle-by-nozzle shut-off.
Droplet size is controlled for precision spraying.

AUTOSPRAY

During spraying, droplet size management is essential to ensure a successful application.
Achieving higher throughputs means driving faster, which can compromise good and consistent spray quality. The climatic conditions, and the fact that they could change during applications, must also be considered.
In order to maintain excellent spray quality throughout the application, KUHN has introduced the AUTOSPRAY system.

It uses PWM (Pulse Width Modulation) technology that allows the AUTOSPRAY precision spraying system to control the droplet size. Nozzle opening time is varied by micro-pulsation to maintain a constant pressure, regardless of the dose to be sprayed. By keeping the droplet size constant regardless of speed, the AUTOSPRAY system offers users a wider range of speed. Productivity is enhanced, without influencing the quality of the spraying operation.

Spraying couldnt be easier with the ISOBUS terminal. Droplet size can be activated or deactivated with a simple click for optimal spray quality.
By controlling the dose and the droplet size, all components are combined to achieve precision spraying.

RINS ASSIST

The e-SET features the RINS ASSIST automatic rinsing system, as well as other great features.

During the rinsing process, the RINS ASSIST system automates the rinsing sequence based on the amount of product remaining in the machine. The system ensures 1% dilution of the tank residue.

From the cab, the only action required is to indicate the type of rinsing (boom only or complete machine), then follow the rinsing procedure. When rinsing the machine, the RINS ASSIST system controls the level in the tank precisly to adjust the best rinsing scenario to achieve 1% dilution. The system will then successively rinse the incorporation line, the tank via the rotary washers, the control and circulation returns, and then the boom by spraying.
With a METRIS 2 ISOBUS sprayer, the terminal displays the progress of the operations directly, and you can see precisely where the water comes from, and where it is sent to.
The rinsing operation is carried out effortlessly to 1% dilution. The sprayer is then ready for other applications as soon as it leaves the field.

TRACK ASSIST

With the TRACK ASSIST axle, the sprayer remains in the tractor's path at the headland of the field, or when following curves in the field. The crops are protected and preserved.

The METRIS 2 sprayer's TRACK ASSIST axle ensures perfect tracking between the wheels of the sprayer and those of the tractor. It reacts precisely in response to the speed information received. Axle sensors at the rear of the machine are integrated into the sprayer structure - no risk of the information being disturbed by vegetation. At the front, a single gyroscopic sensor, placed on the tractor allows you to read its trajectory, to follow it with the sprayer.

The combination with the GPS Section Control allows the tag axle to automatically realign itself when in reverse: no driver action is required!
