If your tractor does not have enough spool valves to control all the hydraulic functions of your vehicle, it is necessary to add an electrohydraulic solution to your machine. In this case, electrically controlled hydraulic valves are fitted on the side of the chassis and gather all or part of the hydraulic functions of your machine. This control system is protected by a metal casing against water, mud, etc. from the working conditions. This concept consists of an aluminium entry block with a capacity of 60 l/min or 120 l/min, onto which the different solenoid valves, each representing a function, are fitted. As standard, the hydraulic installation is equipped to work in a closed circuit called "Load Sensing", but an ergonomic bypass also allows work in an open circuit, i.e. with tractors without Load Sensing.
The multifunctional control box is the most ergonomic and efficient solution to easily operate the increasing number of hydraulic functions on modern agricultural machinery. With this installation, it is possible to feed from 2 to 14 hydraulic functions, by means of one single hydraulic distributor on the tractor via solenoid valves, which are controlled from a single control box in the tractor cab. This box is specific and custom-made: it has no "empty buttons" and only includes the configuration of your machine. Made of aluminium, it is robust. A special seal protects it against water and dust. In addition, it is fitted with a quick coupling for an easy disconnection and storage after use.
What is Isobus? Definition according to the AEF - Agricultural Industry Electronics Foundation: “Electronics improve the safety, efficiency, precision and performance of agricultural equipment. In the past, each manufacturer used its own patented solutions that had to be adapted specifically to each tractor and equipment combination. The universal 'plug and play' solution offered by ISOBUS will simplify things for the future: one terminal for a wide range of equipment, regardless of the manufacturer.” At JOSKIN, the control box interface, just like the automaton interface, can be replaced by the ISOBUS terminal already installed in the cabin of the tractor, if it is equipped with one, or by a JOSKIN terminal. Thanks to this system, one single control box in the cabin replaces several ones: a direct way to high-tech agriculture! This system centralises, for instance, the electrohydraulic controls, the pressure sensors, the management of the injection implements, the flow rate proportional to the driving speed, or the dynamic weighing system. The terminal is also compatible with a GPS system for a precise guidance when spreading on different plots. Most tractor manufacturers are using this technology.
With the ISOBUS technology to control your vehicle, you can use either the standard tractor display or one of the optional Iso-CONTROL displays supplied by JOSKIN. Available in 2 versions and sizes (5.7” or 10.4"), these touch screens are used to manage all electro-hydraulic functions of your machine, depending on the chosen configuration. The Iso-CONTROL 306 offers a USB key plug-in for data export, while the Iso-CONTROL TOUCH 1000 features GPS and analog camera connections, 2 USB ports and a double display.
JOSKIN offers several types of hour counters: cardan shaft rotation counter, vibration counter, etc. This allows you to easily monitor the use of your machine park (e.g. for rentals, in agricultural cooperatives, etc.).
The Ferti-CONTROL 320 is a control box for the muck spreader functions, e.g. the proportional moving floor control. It can also be used to control the lights and flashing beacon.
The Easy-CONTROL is an automaton that controls all the electrohydraulic functions of the machine. Operation is particularly intuitive, thanks to a combination of physical buttons and a central multifunction thumb wheel. This control box is the ideal solution for mid-range machines, with the possibility of upgrading to ISOBUS. On muck spreaders (with vertical beaters), it includes basic functions (moving floor unloading, control of lights and flashing beacon) and advanced functions (electric reversal of moving floor rotation and control of guillotine door and limitation boards).
For precision spreading, JOSKIN offers an electronic spreading management system (proportional flow system) available on ISOBUS and Easy-CONTROL.
During the use, the operator indicates the loaded volume (full load, half load, etc.), the desired output per hectare (in m³ or t/ha), the effective working width as well as the product density. If the system is combined with a weighing device, the operator must first validate the load on board, which is indicated by the device. With this data and the selected loaded volume (full load, half load, etc.), the density will be calculated.
The operator then chooses the position of his door according to the material to be spread. Once this information has been entered into the terminal, the moving floor drive is automatically adjusted according to the required flow rate and the driving speed of the spreader.
The regulation operates in closed circuit and the moving floor speed is continuously monitored. This system ensures that the required moving floor speed is maintained, even if the body is almost empty or, on the contrary, if it is well filled and the spreader drives on a slope.
