UX Super trailed sprayer

Electrically controlled TG valve chest
The TG part-width valve chest with up to 13 part-width sections is available with ISOBUS control. The part-width boom sections are quickly switched on and off without drips via electric motor valves with pressure relief. The spray rate is precisely and quickly controlled directly by the machine’s job computer in all situations.

Single and multi-nozzle bodies
The nozzle bodies with integrated diaphragm non-return anti-drip valves in the profiles reliably prevent dripping from the nozzle. Self-adjusting bayonet fixings ensure a tool-less quick nozzle change. The 3-fold or 4-fold nozzle bodies are suited to frequent nozzle changes due to different applications and crops. AMAZONE offers a wide range of nozzles from agrotop, Lechler and TeeJet.

The AMAZONE DUS pressure recirculation system ensures a reliable circulation throughout the entire system. When starting the spraying operation, all the hoses including the spray lines are filled under pressure in the reverse direction with the mixed spray agent. This means the spray lines are always full and immediately ready to use across the entire working width. There is no waiting on the headland.

Every time individual part-width sections are shut off when turning and during transport, the spray agent continues to circulate thanks to the pressure recirculation system. This reliably prevents deposits, blockages or segregation in the spray lines.

During the cleaning operation, fresh water flushes the spray lines out right up to the nozzles without any spraying being necessary. During this cleaning procedure, the concentrated spray agent is returned back to tank via the pressure recirculation system leaving the spray lines clean.

DUS pressure recirculation system with part-width section switched off

The simple solution for automatic 50 cm part-width section control 
With AmaSwitch plus, AMAZONE offers a precise solution for automatic part-width section control with 50 cm part-width sections. AmaSwitch plus is the ideal alternative for operators who want to maximise the benefits of very precise switching in wedge shaped fields and areas of overlap, thanks to the 50 cm part-width section control.

The standard equipment for the AmaSwitch plus includes the DUS pro high pressure recirculation system and, in addition, it can be equipped with LED individual nozzle lighting.

Equipped with the DUS pro pressure recirculation system as standard 
As in the case of DUS, the spray pressure in DUS pro is constant up to the individual nozzle and remains at the pre-set spray pressure. In addition, minimal residual spray volumes
are achieved thanks to the conical spray lines.

DUS pro – constant spray pressure with minimal residual volumes
 

Triple nozzle body with electric on/off switching

The AmaSwitch plus technology is based on a conventional manual-rotating triple nozzle body with electric on/off control of each individual nozzle. Opening and closing is achieved via an electric valve which is mounted directly on the nozzle body. In conjunction with GPS Switch, it is therefore possible to switch the 50 cm section width very precisely in wedge-shaped fields and on headlands. In addition to the automatic switching using 50 cm part-width sections, it is also possible to configure the desired number of part-width sections from choice.

Quad nozzle body with electric on/off switching
In addition to the triple nozzle body, AmaSwitch plus electric individual nozzle control can also be equipped with a quad nozzle body. 

With true 25 cm nozzle spacing
The quad nozzle body enables genuine 25 cm nozzle spacing to be achieved with the aid of the optional off-set kit. This offers the benefit, in combination with special 80 degree nozzles, of reducing the boom to target surface distance down to less than 50 cm.

Quad nozzle body with automatic electric nozzle changeover
The electric AmaSelect individual nozzle control consists of a quad nozzle body with electric on/off control and, additionally, the remote changeover of the nozzles. In addition to the 50 cm part-width sections, which can be switched automatically via GPS-Switch, the system offers electrical switching between the 4 mounted nozzles via the operator terminal - or even completely automatically if the forward speed or application rate is changed. This offers the possibility, for instance when leaving the optimum pressure range of a nozzle, to switch on a second nozzle or to changeover to a larger nozzle.

Flexible configuration of boom widths and part-width sections
AmaSelect enables any number of part-width sections with any number of nozzles to be freely configured. So for farmers or agricultural contractors with different tramline systems, a simple matching of the nozzle switching with the relevant working width is possible.

Automatic 50 cm part-width section control via GPS-Switch with Section Control
The automatic control of individual nozzles in 50 cm part-width sections is made possible by combining the AmaSelect individual nozzle control with GPS-Switch (with Section Control). This enables the amount of overlap to be considerably reduced, meaning that there is a significant saving in spray agent. 

With true 25 cm nozzle spacing
As an option, the AmaSelect nozzle body can also be equipped with an off-set kit giving 25 cm nozzle spacing. This offers the benefit, in combination with special 80 degree nozzles, of reducing the target area distance down to less than 50 cm. 

HeightSelect – always the optimum target surface distance
With the aid of HeightSelect (only in conjunction with AmaSelect and ContourControl) now also the distance between boom and the targeted crop is continuously matched automatically in relation to the nozzle spacing and nozzle type. When the nozzle has been switched on, the automatic boom guidance system controls the appropriate target distance. This automisation improves the efficiency of the crop protection agent used as well as decisively relieving the stress on the driver.

High-End as standard – LED individual nozzle lighting and DUS pro
As standard, AmaSelect is equipped with DUS pro high pressure recirculation and LED individual nozzle lighting.

The crop protection technology of the future is already here
The AmaSelect single nozzle control offers the potential for absolute precision by utilising the additional optional AmaSelect CurveControl, AmaSelect Row and AmaSelect Spot functions.

Precise switching with 50 cm part-width sections
The decisive benefit of individual nozzle control is the possibility to operate with small part-width sections giving an even greater degree of accuracy in wedge shaped fields, short work and on the headland. If AmaSwitch plus or AmaSelect is combined with the automatic GPS-Switch part-width Section Control, automatic switching of individual nozzles in 50 cm part-width sections is possible. With this system, areas of overlap are significantly reduced and are, in comparison with a conventional Section Control part-width section shut-off system, up to 85% less. So, the combination of GPS-Switch and individual nozzle control results in, depending on field shape and size, the working width and number of part-width sections, significant savings in spray agent compared with a normal spraying system used thus far.

Calculated example:
Annual average overlap of conventional part-width sections vs 50 cm part-width sections in combination with Section Control

Important knowledge for field analysis

• Average overlap with 50 cm part-width sections only 1.92%
• Average overlap with 9 part-width sections 7%
• Short payback period for larger farms due to the annual potential savings
• Due to smaller field sizes, smaller farms save proportionally more
• When growing crops with a high crop protection demand (e.g. potatoes, sugar beet), 50 cm part-width sections are particularly cost-effective

Optimised application when driving round bends

Constant application rate
AmaSelect CurveControl offers a precise solution for keeping the application rate as constant as possible across the whole of the working width when driving round bends. The CurveControl function is equipped as standard in conjunction with AmaSelect and the ContourControl active boom guidance.

The problem: over- or under-application when negotiating bends
In the past, the distribution of plant protection products when driving round bends has led to an over-application on the inside of the bend and an under-application on the outside of the bend. The problem increases with increasing boom widths. Over-applying on the inside of the boom must be viewed more critically, as potential overdose levels of more than 300% are possible.

The solution – AmaSelect CurveControl 

The operation of the system is supplemented by a useful function specifically for bends in the form of CurveControl for the AmaSelect electric single nozzle control. In addition to the nozzle pressure, CurveControl uses sensors to determine the curve radius and automatically calculates the pressure adjustment for the changed flow rate. The system then balances the application rate in the boom independently of the part-width section by means of automatic nozzle changing in the boom. 

Benefits of AmaSelect CurveControl: 

• Virtually uniform application rates when negotiating bends over the entire working width
• Optimum crop management
• Prevention of resistance caused by under-dosing

Accurate band spraying at the press of a button to reduce the use of plant protection agents

Row-specific band spraying
AMAZONE offers the AmaSelect Row function for the AmaSelect electric individual nozzle control for remote switching from full-area application to row-specific band spraying. Row-specific band spraying with special 40° nozzles makes it possible to reduce the consumption of plant protection agents by up to 65%.

Maximum operational comfort 
The area to be treated by band and full-width spraying as well as the desired application rates of the two types of spraying is stored via the fill menu, and the required filling quantity is automatically calculated, in order to minimise residual spray volumes. The row spacing, spraying angle and application height of the nozzles are easily adjusted via a separate menu in the ISOBUS machine controller. The selection of the right nozzle and the associated nozzle positions to the band needing to be treated is carried out automatically. It is then possible to switch between band and full-width spraying in a matter of seconds at the push of a button on the ISOBUS terminal.

Advantages of AmaSelect Row: 
Highly efficient band spraying in row crops – and all at the touch of a button
Different row spacings possible thanks to the optional off-set kit at 25 cm
High operating comfort with an integrated filling menu with fill quantity calculation
Reduction in plant protection agent usage by up to 65%

Different row spacings
Row-specific applications in crops with a 50 cm row spacing can be implemented very easily without any further retooling. However, the optional off-set kit for the AmaSelect nozzle body with a 25 cm nozzle spacing also enables band applications to be implemented in crops with a 75 cm row width. Only the nozzles at the desired spacing are switched on for that purpose. Alternative row widths, e.g. 45 cm for sugar beet, can also be realised with an additional nozzle arrangement and a connecting hose.

Full-width application with AmaSelect CurveControl in the outer area
Comprehensive full-width application is recommended for the outer area of fields. The advantages of CurveControl are particularly evident in fields with curves. Furthermore, obstacles at the edge of the field can be avoided during full-width application without any problems. In addition to this, the matching to the seed drill is not always exact on the headland. This has a negative effect on band spraying.

Changing to band application at the touch of a button
The material can then be applied sparingly in the inner section of the field using AmaSelect Row. The full-width application can be easily changed to band application on the terminal for this purpose. Absolutely straight rows and exact matching up to the seed drill are the prerequisites for the use of AmaSelect Row. The application rate is automatically adjusted in this respect.

Particular aspects of band application
The perfect use of band application depends on several factors:

1. The nozzles must be at the right application height when they come on.

• Automatic boom lowering with the AmaTron 4 ISOBUS terminal and GPS-Switch

2. Precise maintenance of the distance to the target surface required for a uniform band width and even concentration of the plant protection agent 

• ContourControl active boom guidance for the optimum target surface distance 

3. Smooth boom ride over the entire working width 

• SwingStop and SwingStop plus vibration damping for reducing the horizontal boom movement 

4. Precise vertical alignment of the nozzles directly over the band 

• Flexible extension kit for precise alignment of the nozzles in all row spacings

Part-area, site-specific plant protection treatment on the basis of spot application maps

Part-area, site-specific weed treatment
To reduce the use of crop protection agents, AMAZONE offers AmaSelect Spot, an individual nozzle control system which allows part-area, site-specific weed treatment based on highly accurate spot application maps. External service providers produce the spot maps.

Targeted spot application 
The second step is the treatment of the weed areas in the field. All that is required for this is to load the spot application map in the AmaPad 2 ISOBUS operator terminal. In contrast to full-area treatment with the AmaSelect single nozzle control system, only those areas where weeds are present are treated during the pass.

Benefits of AmaSelect Spot:

• Precise spot treatment of weeds with a standard Amazone crop protection sprayer
• Reduction in plant protection agent usage by up to 80 %
• Better protection of the environment
• Minimal residual spray volumes, thanks to exact planning of the application rate using the spot application maps
• Prevention of resistance thanks to the small-area spot application with 100% plant protection agent concentration

Scanning the area and creation of spot maps for weed treatment
In the first step, the field to be treated is scanned and a spot application map created. Depending on the service provider, various processes are used for scanning the area in this first step, such as overflying with a drone, by satellite or via special sensor booms.
