To easily operate the increasing number of hydraulic functions on agricultural machines while protecting the material and the meadows, an automatic management system is absolutely necessary.
A. Electronic management: Automaton
Part of the standard equipment on the whole range, the automaton manages the different eletro-hydraulic functions by a programmed sequence, depending on the chosen implement. The Touch-Control control box is an ergonomic and efficient solution to easily control a combination of hydraulic functions of a spreading implement. This touch screen is installed in the tractor cabin.
The spreading sequences differ from one implement to another. That is the reason why there are all recorded in the computer memory. The implement hitched to the vehicle then only has to be selected, which allows an easy use and change of implements.
In automatic mode, the START key launches the registered sequence: opening the feeding valve, starting the macerator, lowering the implement, etc.
A manual mode is also available in order to act on some functions during the sequence.
According to the chosen injector and sequential block, several hydraulic functions will be necessary.
If the macerator is operated by means of an electro-hydraulic box, a high flow entry block is then indispensable to increase the output of the hydraulic motor and prevent load losses and overheating problems.
The machines fitted with electrovalves gathered on a monoblock basis are protected by a galvanized box. This hydraulic distribution installation includes an inlet block (capacity: 60l/min or 120l/min). Most hydraulic functions of vehicles require a low flow but it is very important to know the functions that require a high one. A high flow is especially needed for hydraulic motors, e.g. those of the turbo filler, macerator(s), etc. For the functions requiring a high flow, there are two possibilities: a high-flow electro-hydraulic control and a flow deflector.
The multifunctional control box is the most ergonomic and efficient solution to easily operate the increasing number of hydraulic functions on agricultural machines. Thanks to this installation, it is possible to feed from 2 to 14 hydraulic functions, by means of one single hydraulic distributor on the tractor, via electrovalves. These electrovalves are controlled by means of one single control console in the cabin of the tractor, the multifunctional electro-hydraulic control box.
The interface of the JOSKIN control box, just like that of the automaton, can be replaced by the ISOBUS terminal that is already present in the tractor cabin. If there is none yet, the JOSKIN terminal can be delivered.
The aim is to ensure the communication between different tractors and the many implements (and vice versa) through a standardized language. This international standard is ever more used and allows a quick and easy connection ("plug & play") between various brands.
The AUX-N feature allows to match any Isobus function with a compatible AUX-N Joystick. On top of making it easier to use, the AUX-N feature allows to select the functions associated to the Joystick.
Variable rate-control - Allows to process application maps in Shape format. Up to 5 different flow rates are possible. They are specified by means of maps with theoretical values. Applications are adapted in a specific way to the location, according to the regulations.
Track-Leader Top - Carries out an automatic guidance via the TRACK-LEADER functions. Besides the App, the system includes an extra guidance computer and a GPS-receiver. The automatic guidance relieves the driver, increases the yield performance per surface and reduces the diesel consumption.
Track-Leader - Allows to have parallel tracks with different driving modes. The guiding direction and the bypass force are displayed on the screen. The software also gives information about the spread area and writes the tracks and field edges to memory.
Section-Control - Allows the automatic activation and deactivation of the machines and an automatic partial width change. As soon as a section spreads party of totally on an already spread area, it is deactivated.
ISO CONTROL allows, for instance, to centralize the electro-hydraulic controls, the flow meter, the pressure sensors, the Section Pilot, the GPS, etc.

All arable injectors (TERRASOC, TERRADISC, TERRAFLEX/2 and TERRAFLEX/3) and meadow injectors (MULTI-ACTION and SOLODISC) with sequential block include, standard or as an option depending on the model, a system allowing to lift the injector on wet spots. This device is made up of a valve allowing to lift the rear implement when going from a dry area to a humid one, while the feeding valve and macerator remain active.
The IsoBus application can control the "Section Control" to automatically open/close the different sections of a slurry injector or spreading boom combined to the spreader itself.
An outer GPS antenna receives the position according to the Section Control standard and the IsoBus application compares it with the previously recorded positions in order to close the sections on areas that have already been fertilized.
For an optimal use of the spreading tool, the user-friendly and environmentally acceptable character of the machine and the protection of the grass and the material, an automatic control system of the hydraulic functions of any injector is absolutely necessary.
It operates the hydraulic functions that are linked to the working of the spreading implement. Their automated sequence allows the driver to only care about the lowering or lifting and the unfolding of the spreading implement.
Example (depending on the chosen sequential block):
• lifting/lowering the tool (driver);
• lowering speed two times faster in relation to the oil supply of the tractor;
• opening of the slurry feeding valve;
• starting the macerator(s);
• control of the automatic reverse of the macerator;
• opening-closing the hydraulic anti-drip pincers on SOLODISC meadow injectors;
• constant pressure according to the height differences;
An excellent flow rate is necessary to spread with accuracy!
JOSKIN has therefore developed to that end an electronic flow meter (Ø 150 or 200 mm) delivering an exact flow at any time. Whatever the driving speed, the spreading pattern remains uniform thanks to the system adjusting the flow in proportion to the advancement speed (DPA).
The flow meter constantly measures the slurry injection flow while sensors, fitted in the wheels, measure the driving speed.
By interpreting these data, a computer will automatically regulate the slurry flow according to the driving speed, by way of an electric valve. This device requires an ISO terminal.
Integration of Slurry Analysis on JOSKIN Tankers
In collaboration with John Deere, JOSKIN offers a real time technology thanks to an infrared lens (subject to availability in your country). The slurry composition (total nitrogen (N), phosphorus (P), potassium (K), ammoniacal nitrogen (NH4) and dry matter) is measured in real time during spreading. JOSKIN integrates this analysis system on its tankers fitted with a proportional flow meter by ISOBUS. The whole allows the DPA to integrate a spreading instruction expressed in units of nitrogen / ha (for example) and not in m³ / Ha as a conventional DPA system.
