Pantera 4504 self-propelled sprayer

The 4,500 litre spray agent tank (actual volume 4,750 litre) positioned deep in the frame ensures a favourable centre of gravity and an even weight transmission to all four wheels of the Pantera. The spray agent tank consists of high grade glass fibre reinforced plastic with smooth internal and external walls. The low positioned outlet sump ensures the smallest of residual volumes even in sloping terrain. Electronic fill level indication and four rotating high-pressure nozzles for internal cleaning are standard. The 500 litre fresh water tank with fill level indicator is located at the rear of the Pantera.

The two high-capacity piston diaphragm pumps with a pump capacity of 520 l/min in the Pantera 4504 ensure that spraying is possible at high water rates and high forward speeds but sufficient agitation capacity is always available. The pump speed from 380 to 580 rpm can be selected via AmaDrive. The pumps are positioned on the right-hand side of the machine and are easily accessible.

The tank dome cover is completely developed and manufactured by AMAZONE and is unique on the market. The ergonomic handle makes it simple to open and close with little effort. The tank dome lid is robustly designed and optimally closed by the 8-fold locking system.

The automatic fill stop prevents overfilling of the machine when filling via the suction hose. Automatic fill stop is optionally available for the bowser fill port. The bowser fill port is located up front in the storage compartment, which allows pressure filling from the edge of the field without having to fold in the boom.

HighFlow⁺ allows both pumps to be used for spraying. If the normal spray output of 200 l/min is not sufficient, the liquid flow from the agitation pump is automatically used as required until the desired application rate is reached. The remaining capacity of the agitation pump continues to be used for agitating the liquid in the spray agent tank.

• Large amounts of liquid fertiliser can thus be applied at higher speeds
• In vegetable farming, application rates of up to 2,000 l/ha at speeds of 5 to 6 km/h are possible

The operating components of the Pantera with Comfort-Pack

1. Induction bowl
2. Hand lance pistol for rinsing out the induction bowl
3. Self cleaning pressure filter
4. Suction filter
5. 7-way pressure tap
6. Soap dispenser
7. Control tap for induction bowl

10. Hand wash tank tap
11. Fill port for fresh water tank incl. Gardena coupling
12. Control tap for venturi/induction bowl draw-out/additional filling capacity
13. 3” Camlock suction port

In conjunction with Comfort-Pack, the TwinTerminal 3.0 is also utilised. In addition, automatic fill stop for the suction fill is also included. As an option, fill stop is also available when pressure filling from a bowser. During application, the intensity of the agitation is regulated depending on the tank fill level. As the fill level decreases, the agitation capacity is automatically reduced down until it is completely switched off preventing the formation of foam at a low fill level. In addition, the automatic agitation regulation offers auto-dynamic agitator control. This means: the auxiliary agitator is closed when a higher application rate is required at the boom. 

After the spraying operation is finished, Comfort-Pack provides fully automatic cleaning which can be controlled completely remotely from the cab. Additional functions such as boom rinsing, cleaning the spray liquid circuit from heavy deposits or a defined dilution of a subsequent tank mix in the field are all functions included within Comfort-Pack.

The benefits:

• Comfortable filling of the spray agent and fresh water tanks via the automatic fill stop 
• No foaming of the spray agent due to the automatic fill-level dependent control and switching off of the agitator
• Always maximum capacity when spraying and agitating thanks to the auto-dynamic agitator control
• Remote-controlled, automatic cleaning programs for the complete sprayer wash-out

The 7-way pressure tap provided in the Pantera with Comfort-Pack is extremely practical. As opposed to a normal pressure tap, the in-house developed valve from AMAZONE consists of a cam and seat valves. Exclusively by swivelling in and out the handle on the pressure tap, the relevant liquid paths are reliably opened or closed.

The benefits:

• All functions on the pressure side are actuated via a tap
• Minimal wear of the seals and insensitivity to sand and suspended matter in the water
• An unwanted path is not activated when changing the function

Handling is made especially comfortable by Comfort-Pack plus. Instead of operating taps, TwinTerminal 7.0 makes machine operation much easier with its pressure-sensitive touchscreen. The complete control of the spray agent circuit is carried out solely via the pressure-sensitive touch screen which functions perfectly even when wearing gloves. The user just selects the desired function and the sprayer adjusts itself automatically!

In the job computer, two individual filling profiles for different operators or applications can be stored. Then only the hose has to be coupled for filling, and the machine automatically fills the spray agent tank and fresh water tank up to the desired tank fill level. As an option, the operator can select individually an adjustable pause in the filling of the spray agent tank.

Comfort-Pack plus includes a fresh water pump with an output capacity of 160 l/min. This can be used to supply the induction bowl with fresh water from the fresh water tank during bowser filling.

The fresh water pump can be used to fill the fresh water tank and the spray agent tank in parallel via the suction port. The additional fresh water pump also enables faster cleaning of the Pantera.

The complete sprayer along with the induction bowl can be cleaned fully automatically. For this purpose, the Pantera with Comfort-Pack plus is equipped with the following cleaning programmes: intensive clean, quick clean and boom rinsing.

In addition, after every fill, the induction bowl rinses itself on its own. 

Perfect operator comfort via the simple and centralised controls

The induction bowl is located directly in front of the control panel and holds 60 l. The conical form of the bowl together with a central outlet and an enormous suction rate of more than 200 l/min ensures fast and trouble-free filling and complete emptying.

The benefits:

• Suction rate of more than 200 l/min – for fast and trouble-free filling and complete emptying
• Infinitely variable mixing nozzle – prevents any clogging of powdery and granular spray agents
• Infinitely variable high-capacity rinse ring
• In conjunction with Comfort-Pack plus, the induction bowl can be permanently supplied with high water pressure via the fresh water pump during bowser filling.
• Dust- and leak-proof induction bowl lid as a practical storage option with integrated drain-off device
• Canister rinse nozzle with practical pressure plate for cleaning the measuring jug and canisters
• Small contact area on the canister rinse nozzle where the nozzle can be activated for cleaning the canister neck

Why use DirectInject?
The demands on farmers and technology are constantly increasing with regard to plant protection. Flexibility in the selection of plant protection agents in the field becomes an increasingly important point here. From a plant establishment perspective, the needs-based application of specific products and active ingredients only in sections or on individual fields is a frequent response. There are also restrictions relating to protection-sensitive fields and bodies of water which farming must consider when selecting the appropriate plant protection agents. 

System overview 
DirectInject from AMAZONE is a system for the direct injection of plant protection agents. These can be injected or stopped during application as required. The special feature of DirectInject compared to conventional systems is the fast response time of the injection and its complete integration in the spray agent circuit and operation of the sprayer. DirectInject consists of an additional 50 l tank with its own metering system which is integrated between the cab and the main spray agent tank.

The advantages at a glance:

• Flexible, fast and needs-based use of 
• plant protection agents
• Optimum crops
• Environmentally-friendly
• Saving on:
  • Working hours and labour costs
  • Machine costs
  • Plant protection agents

Application in the field
If the driver of the Pantera notices e.g. a prevalence of unwanted weeds which need to be controlled in a specific part-area, they can activate the DirectInject metering system from the cab at the touch of a button. The supplementary product from the DirectInject tank is then added to the spray agent from the spray agent tank in the mixing chamber. The optimised reaction time compared to conventional systems is achieved by a twin-line system. Pre-mixed spray agent from the spray agent tank and the plant protection agent from the DirectInject tank are held in a second spray line in the boom. When the direct feed system is activated, the mixture is supplied to the nozzle bodies via several injection points on the boom and applied. This guarantees minimal reaction times. In this regard, the valve for the spray agent from the spray agent tank and the valve for the second spray line with the pre-mixed DirectInject agent are switched alternately, meaning that spray agent is only taken from one line at any time.
