Trailed sprayer METRIS 2

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

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.

The LEA3 boom also incorporates the well-known strong points of the entire range:

• Protection of the nozzles over the entire boom width
• 3-dimensional safety
• Bowl filters on each section
• Quadrijet nozzle holders

The robust RHA3 boom is equipped with the EQUILIBRA suspension system and designed to last. Available in widths from 30 to 38 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 roads is 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 RHA3 boom was particularly adapted for precision spraying equipment. The boom can be equipped with CCE or MULTISPRAY circulation systems and BOOM ASSIST systems. The spraying equipment is protected in all directions along the entire length of the boom by the boom's structure.

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.

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.

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.

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.

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!
