A stable and manoeuvrable sprayer

With a hitch-to-axle length of 4 m (2,400-L/3,000-L) or 4.30 m (3,800-L) and height of 3.10 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 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.

Well-positioned tanks

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 320/400-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.

Keep all the elements within arm's reach

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.

Stable and durable booms

EQUILIBRA suspension frame for MES2, MEA2 and RHPA booms

EQUILIBRA suspension: keep the boom parallel to the chassis!

The EQUILIBRA suspension system allows the boom to remain perfectly parallel to the ground when driving over rough terrain. EQUILIBRA suspension gives your boom natural stability thanks to its pendulum links (for rotation and sideways shifts) and shock absorption system. The boom runs smoothly over the ground and the crops and no longer shifts and drifts!
The EQUILIBRA suspension is designed for work in intensive conditions and includes as standard an independent left/right anti-whiplash system to protect the boom, especially when turning, accelerating and braking.Finally, a hydraulic tilt correction system and springs keep the boom parallel to the chassis when operating on bends.
EQUILIBRA suspension in a nutshell:

Pendulum suspension for rotational movements
Link rods for radial movements
Shock absorbers to dampen any bounce
Independent left/right anti-whiplash system
Hydraulic tilt correction and springs

Simple and complete operation

A simple and well-designed spraying circuit

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.
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!

MANUSET operation

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 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 complete turn 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.

MANUSET manual operation, simple and economical

DILUSET+ operation

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

Quick and safe incorporation of chemicals

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.

No more blockages with quadruple filtration

The LEXIS trailed sprayer is equipped with four levels of filtration:

At filling
At suction
At discharge
At boom sections

All filters can be cleaned even when the sprayer tank is full.

Equipment

Numerous optional equipment is available that can provide operational comfort which can be adapted to meet all requirements.

Available drawbars and hitches

The different LEXIS trailed sprayer hitching systems may include a low hitch or high hitch drawbar, with a 50 mm or 40 mm ring hitch, a K80 ball hitch, or a 35 mm swivel hitch. Optionally, a self-steering drawbar (mechanical or hydraulic) allow it to follow the tractor's tracks. (restrictions according to country approval)

Piston-diaphragm pumps (PD) or centrifugal pumps (CP)

The LEXIS sprayer can be equipped with various pumps according to your requirements. Whether it's a high-flow centrifugal or diaphragm piston type, it allows the main tank to be filled in just a short time. You spend less time at the filling station to make better use of your time in the field and increase your throughputs.

Several unfolding solutions are available on each boom

Hydraulic boom folding/unfolding solutions

Different unfolding kinematics are possible with the various booms available for the LEXIS sprayer.
The boom is unfolded by first selecting the desired functions on the spray terminal and then by operating the tractor's control valve.
As an option, the CH10 control box is used to control each function independently. The sprayer then uses the tractor's continuous pumping feature to provide oil for the machine.

Several types of continuous circulation for higher accuracy

The LEXIS can be fitted with the following continuous circulations for higher accuracy, reduced clogging and easier rinsing and priming of the boom:

Hydraulic continuous circulation CCH: Low pressure circulation with opening management by sections.
Electric continuous circulation CCE: High pressure circulation with nozzle opening management.
AUTOSPRAY: High pressure circulation with smart PWM nozzle holders. Nozzle opening management.

An innovative ISOBUS joystick

With the new CCI A3 joystick, you directly view your machine's functions on the joystick's touchscreen. Thus, you select the right function at the right time. The CCI A3 is certified ISOBUS AUX-N by the AEF, it is compatible with all ISOBUS AUX-N certified ISOBUS machines. For the display of the functions on the joystick, check the compatibility.

The booms are equipped with 2 or 3 ultrasound sensors which measure and correct the boom height in real time.

Automatic BOOM ASSIST height control system

BOOM ASSIST keeps the boom in the correct position regardless of field topography, automatically adjusting the height, tilt (SLANT PRO) and independent variable geometries (TOTAL PRO) or both (ExTREME). Keeping a boom at the ideal height optimises spray distribution and particularly reduces losses due to wind drift and evaporation.
There's no need to worry about the boom, the sprayer manages it automatically.
