The ZA-M Profis Hydro and ZA-M Ultra Profis Hydro weigh cell spreaders with hydraulic spreading disc drive provide complete independence from the engine speed and the forward speed. The spreading discs and agitator shaft speeds are electro-hydraulically regulated and monitored. Modern tractors with load-sensing hydraulics management systems can always be driven in the optimum speed range and therefore save fuel when in operation. The main benefits of this drive system are evident when using the variable working width control at the edges of the fields and when spreading in wedges. A pre-programmed 6 section part-width section control prevents major over-fertilisation or under-fertilisation.

Economical, and in particular, extremely ecologically sensitive mineral fertilising requires responsible minded actions. According to new environmental directives, environmentally harmless fertilisation on the field edge is not possible without modern border spreading systems. All of the requirements of the current fertiliser ordinance can be perfectly met with AMAZONE boundary spreading equipment.
Tele-Set-disc: You can change over from normal spreading to side, boundary or water course spreading by means of a tool-less disc change.

The Limiter is a modern boundary spreading system that is used if the first tramline is half the working width of the fertiliser spreader in from the edge of the field. It is used for side, boundary and water course spreading.
The decisive advantage with the Limiter is that there is no need to stop, interrupt the spreading operation or dismount from the tractor.
With AMADOS+ and AMATRON 3, the quantity is automatically reduced on that side during boundary and water course spreading when the Limiter is swivelled down.

The hydraulic drive of the spreading system in combination with AMATRON 3 offers every possibility e.g.:
• Side and boundary spreading on both sides in accordance with the individual preselection of disc speed and spread rate
• 6-section part width shut off with automatic spread rate adjustment
• All procedures can be readjusted as required whilst working
• Use of GPS-Switch with automated, position-accurate shut off
Wedge-shaped spreading provides even, non-overlapping spreading in short work. By reducing the throwing width and reducing the flow rate at the same time the actual spread rate (kg/ha) remains constant over the entire area.

The fertiliser spreader is switched on and off fully automatically with accurate positioning provided by means of exact location via the satellite navigation system (DGPS). The same applies to the exact adjustment of the working width.

GPS-Switch is an optional on-board computer which carries out the on/off switching procedures on the headland and in border zones at the correct position using GPS. The on-board computer learns where the field borders are when the tractor first drives around the field with the border spreading system switched on.

On the basis of these borders, the position at which the machine is to be switched on and off or where the working width requires adjusting are defined by the on-board computer depending on the machine parameters (working width, throwing width etc.).

The on-board computer automatically detects whether it is an area that has already been worked and switches the relevant part-width section of the machine off if necessary. A module has been integrated into the ZA-M spreader that takes the differing throw of the spread fan behind the machine into consideration. For example, using this technology, the machine is switched off in a different position when it drives into the headland than when it is driving out of it.

 GPS-Switch makes it possible to work exactly and conveniently at any time of the day or night.

The GPS track parallel guidance system proves to be a huge help for orientation within the field. It features different track modes, such as A-B line, contour following and an obstacle function. The tracks are clearly numbered all the way through. The deviation from the ideal line is graphically shown in the display; clear steering recommendations keep you in the track. Also the distance to the next bout is accurately displayed – for an ideal orientation. Of course, GPS-Track also works as a “stand-alone“ system even without an implement attached.

On-line sensors are currently the best way of providing a requirement-oriented nitrogen supply. All ZA-M spreaders with AMADOS+ or AMATRON 3 provide an optimum connection to all of the on-line sensors on the market (e.g. Yara N-Sensor, MiniVeg N-Sensor, Cropmeter) via the serial interface (RS 232). The fertiliser quantities that are calculated are immediately transferred to the machine's controller via the AMAZONE on-board computer. The actual amount of fertiliser that is spread is recorded for documentation purposes.
 

Automatic field-related documentation (ASD) is a product and manufacturer-encompassing documentation concept for transmitting field-related data between the AMATRON 3 and the electronic field data management system. The digital interface used is published and accessible to all manufacturers.

ASD provides the farmer with the possibility of simply and economically integrating all machines in the documentation chain.

The hopper volume can be quickly upgraded or retrofitted with the S and L extensions. The narrow S-extension gives you a smaller transport width. Direct filling from a tipping trailer or out of big bags is no problem. The wide L-extension is particularly recommended when large industrial front loading shovels are being used.
According to the StVZO, front lights are required for the wide L-extension if there is an excess width. The ladder integrated on the left-hand side provides a better view into the hopper and therefore makes inspection and cleaning easier. The ZA-M Ultra is already equipped with front lights and integrated ladders as standard.

A sensible accessory: the robust castor wheels make it easier to attach and detach the spreader and manoeuvre in the farmyard. The wheels can be quickly removed. It is even easier to attach and detach the spreader using the "Tele-Space" telescopic PTO shaft.

The hopper cover is simply swivelled open before filling. When closed it allows fertiliser spreading to continue, even during bad weather.

A hydraulically operated swivelling cover is available for the ZA-M Ultra that can be opened and closed via a tractor spool valve or via the AMATRON 3.
