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.

JOSKIN has developed a new tool to easily operate the increasing number of hydraulic functions on agricultural machines, while protecting the equipment and the meadows/arable lands: the automatic management system. It is standard on many of the spreading solutions for the JOSKIN slurry tankers and takes over the various electrohydraulic functions in a programmed sequence. The Touch-Control control box is an ergonomic and efficient solution to easily control a combination of hydraulic functions specific to each spreading implement. This touch screen is installed in the tractor cab. As the spreading sequences differ from one implement to another, they are all stored in the ECU memory. The proper implement then only has to be selected, which makes it easier to use and change implements. In automatic mode, the START button launches the recorded sequence: opening the feeding valve, starting the macerator, lowering the implement to the ground, etc. A manual mode can also be selected in order to act on some functions independently of the sequence.
