Pantera 7004 self-propelled sprayer

The TG part-width valve chest with up to 13 part-width sections is available with ISOBUS control. The part-width boom sections are switched, on and off, quickly and drip-free 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 fit up into the boom profiles reliably preventing any dripping at 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 DUS pressure recirculation system – proven more than 10,000 times

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.

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.

AmaSwitch plus includes the DUS pro high-pressure recirculation system as standard and can also be equipped with LED individual nozzle lighting.

With DUS pro, the spraying pressure is constant right up to each individual nozzle and at the set spraying pressure. Thanks to the conical spray lines, minimal residual spray volumes are achieved.

Conical spray line:
The dimensions of the spray line vary along the boom

• Minimum residual volumes
• Even flow speed

1. 15 mm
2. 24 mm
3. 24 mm
4. 20 mm
5. 16 mm

The technology behind AmaSwitch plus is based on a conventional, manually rotated, triple nozzle body with electric on/off switching of the nozzles. Opening and closing is achieved via an electric valve which is mounted directly on the nozzle body. In conjunction with GPS-Switch, it is thus possible to very precisely control 50 cm part-width sections in short work and on the headland. 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.

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 4-fold nozzle body enables a perfect 25 cm nozzle spacing to be achieved with the aid of the optional extension kit. In conjunction with special 80° nozzles, this offers the benefit of reducing the boom to target surface distance down to less than 50 cm.
 

Quad nozzle body with automatic electric nozzle switching

The electric AmaSelect individual nozzle control consists of a quad nozzle body with electric on/off control plus the additional switching over of either a nozzle or a combination of 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 four 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.

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.

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.

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 specific 80° or 90° nozzles of reducing the boom to target surface distance to less than 50 cm.

With the aid of HeightSelect (only in conjunction with AmaSelect), the distance between the boom and the target crop is now also continuously adjusted automatically depending on 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.

AmaSelect is equipped with the DUS pro high-pressure recirculation system and LED individual nozzle lighting as standard.

The AmaSelect individual nozzle control offers the potential for absolute precision by utilising the additional optional AmaSelect CurveControl, AmaSelect Row and AmaSelect Spot functions.

Annual average overlaps 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

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 individual nozzle control and ContourControl active boom guidance.

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.

In addition to the nozzle pressure, AmaSelect 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. 

The benefits:

• 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 usage of plant protection agents

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

Row specific applications in crops with a 50 cm row spacing can very easily be implemented without any further retooling. However, the optional off-set kit for the AmaSelect nozzle body to give 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.

1. Traditional full-width application
2. Band application in sugar beet 50 cm
3. Band spraying in potatoes 75 cm

Via the fill menu, 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, and the required filling quantity is automatically calculated so as 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%

The perfect combination in practice!

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 sparingly applied in the inner area of the field with 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.

The particular features 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 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, a 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.

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.

In the second step, weeds are spot-treated across the surface area. All that is required for this is to load the spot application map in the ISOBUS operator terminal. Unlike blanket treatment approaches, AmaSelect individual nozzle switching lets you treat only those areas where there are actually weeds.

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 build-up thanks to small spot applications with 100% plant protection agent concentration
