Abstract: Installation to be applied to self-propelled or tow-type agricultural seeders that comprises a general command central unit (5) fed from an electric power source and controls a corresponding individual control unit (10) that regulates the operation of the electro-pneumatic unit (6) associated to the seed dosing devices within the seeder to perform the pneumatic action. Electro-pneumatic unit may be a motor suction or a motor compressor unit. The invention envisages the association of these units to all the dosing devices in a seeding body of the seeder, to pairs of dosing units in the seeder, or else, on an individual basis, to each seed dosing device of the seeder.

Abstract: Electric installation specially created for being built into an agricultural tractor for the purpose of providing an electric power source that may be used by any tool associated thereto to perform a specific task. The invented circuit extends from an alternator that takes energy from the tractor and feeds an external electric circuit including at least one output plug or connector. The alternator may take energy from the tractor's engine through a drive pulley, or from the tractor's power take-up. The invention envisages the use of two alternators, one for the tractor installation and another for the external output circuit, both with built-in voltage regulator, wherein the external output circuit includes electronic converters (capable of generating different output voltages) placed before the external contactors and plugs.
