With a hitch-to-axle length of 4 m and height of 3 m (with 21 m boom), the LEXIS sprayer is a very compact machine.
The machine’s short length allows for very short manoeuvring at the headlands of the field, better quality tracking will limit crop damage. The short hitch-to-axle length of the machine allows for flexible manoeuvring. This system makes it easier to enter the fields and reverse in the field corners.
The tank’s shape is specifically designed to integrate the boom into the design and also to limit the height when the boom is folded. The new MTA2 or MEA2 booms are integrated within the machine outline, and cannot come into contact with the tractor cab. The low height of the LEXIS trailed sprayer makes it more stable for transport. Drive on the road and enter the fields in safe conditions.
This compactness allows for fast and easy movement on the road and easy storage of the sprayer.
Efficient tank design: the main tank on the LEXIS sprayer was designed to achieve a low centre of gravity. The largest part of the tank is adjacent to the frame, providing maximum machine stability.
The deep sump allows for tank draining in all conditions, 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 operation.
Maintain balance: the central position of the 320-litre rinsing tank on the axle allows the LEXIS sprayer to maintain good balance in any conditions while also reducing any dead volumes. The centre of gravity of the machine remains along the axis, regardless of the tank level.
The LEXIS sprayer is also exceptionally easy to use. Filling of the rinsing tank? Rinsing tank gauge? All the components are on the operating panel.
The LEXIS sprayer has numerous storage compartments, both for the storage of personal protective equipment (PPE) and for the control box when the machine is unhitched.
To work around the sprayer in safe conditions, KUHN has fitted the LEXIS sprayer with two storage compartments for your personal protective equipment. Your equipment is easy to access before handling the crop protection products.
For transporting larger components, the machine is equipped as standard with a storage platform on the right-hand side.
The booms are made of aluminium which features a density 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 follow the ground, 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.
Aluminium naturally features several advantages.
KUHN has been using aluminium since 1986 to manufacture booms larger than 18m:
Specially designed for MTS2 and MTA2 booms, the TRAPEZIA boom suspension is perfectly adapted to the LEXIS sprayer.
The TRAPEZIA suspension is controlled by two rods that stabilise the boom, as well as two springs that allow the boom to naturally follow sloping terrain. Tilt correction is mechanical and automatic. A hydraulic tilt corrector is available for more specialised applications.
Main characteristics:
The EQUILIBRA suspension with pendulum link 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 without shifts or drifts!
On uneven terrain, the combination of a pendulum and 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 at high speed.
The EQUILIBRA suspension is designed to work in intensive conditions and includes an independent anti-whiplash system, protecting the boom while cornering or during acceleration/braking.
EQUILIBRA 3D suspension: for intensive conditions!
The robust MEA2 boom is equipped with the EQUILIBRA suspension system and is designed to last. Available in widths of 18, 20, 21 and 24 metres, it offers numerous advantages:
The MEA2 boom also incorporates the well-known strong points of the entire range:
Sprayer set-up is a key step in the spraying operation. With two main valves, the total number of filling operations required before rinsing is considerably reduced, and so is the risk of error. With a simple circuit, all sprayer actions are under control. With the LEXIS sprayer, imagine what you can do before even touching a valve!
Even after not having used the machine for quite some time, getting back into the hang of it is easy.
Although easy to use, its shorter circuit allows for reduced dead volumes, which simplifies the rinsing process. When you’re finished spraying, you can be assured that the sprayer is entirely rinsed!
Manual MANUSET operation offers you complete control when preparing your products. With only 2 main valves, all of the sprayer’s functions are controlled from the operator’s control station.
With the 360° multifunction handwheels, reduce handling operations up to 50%. Thanks to an ergonomic design, the valves are easily operated for a simple, trouble-free set-up. Multifunction handwheels make spraying easier.
During rinsing, a 360° rotation with the delivery circuit handwheel ensures that the water drawn in by the pump is conveyed into all sprayer circuits. The rinsing tank level gauge, visible from work station allows for even easier sequencing of the rinsing operations.
Rinsing of the sprayer, or the boom only, from the cab.
Suction filling is programmable and stops automatically when the setpoint is reached. A dual control also allows you to maintain control of all the functions from the operator’s control station.
During rinsing, and without exiting the tractor cab, simply click the terminal to draw in water. Then send it where you want it to go: to the rotary washers to rinse the tank, or directly to the boom to rinse boom pipes, without diluting the spray mixture in the tank.
Finally, the actual volume remaining in the tank can be displayed on the in-cab terminal throughout the entire spraying operation. The management of tank residues is also just as easy.
Available with REB3 / VISIOREB / ISOBUS terminals
The sprayer’s 35-litre chemical induction bowl is characterised by its funnel shape, enabling efficient incorporation of all types of products: liquids, powders and granules. The rinsing system consists of 2 rotary nozzles designed to clean jugs, measuring cups, containers and the chemical induction bowl.
The induction bowl has only one valve through which the active ingredient can be introduced into the circuit. This valve is safely actuated by a foot pedal thus avoiding the need for the operator to bend down. All other operations are carried out using the hand-held lance located nearby, thus avoiding all risk of projection. The induction bowl is rinsed with the cover closed, thereby preventing any risk of splashing or misting.
The bowl filters after the section valves are located on the boom. They are as close to the nozzles as possible to limit the risk of blockages. All filters are cleanable even if the sprayer is full.
