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.

Abstract: An apparatus for transmitting drive motion to the members working in dispensing devices and seed and fertilizer dosing devices, equipped to vary the speed of such drive motions according to the operative needs present in each dosing, comprising, in combination, at least one velocity sensor arranged correspondingly with one of the machine supporting wheels, which sensor is integrated to an electronic circuit including the Intelligent Central Unit consisting of a microprocessor having its own software which commands the movements generated by a plurality of Propelling Units, integrated to the same circuit and arranged, individually, correspondingly with each dispenser and dosing device of the machine, coupled to at least one of the members belonging to the dosing devices and dispensers involved in the drive movement and action of each of them. Liquid and/or granular fertilizer or seed can be dispensed.
