Apparatus and method for obtaining continuous speed ratios in a seeding or fertilizing machine

A drive installation incorporated into a seeding or fertilizing apparatus for obtaining continuous speed ratios without intermediate moveable parts, said apparatus comprising at least one supporting wheel, a drive wheel having a shaft, a dispenser, a plurality of propelling units, at least one dosing device, and a drive movement, comprising, in combination:

• a) at least one velocity sensor arranged correspondingly with one of said machine supporting wheels;
• and,
• b) an electronic circuit including an Intelligent Central Unit comprising a microprocessor having software associated therewith which controls the movements generated by said plurality of Propelling Units, integrated to the same circuit and arranged, individually, correspondingly with each dispenser and dosing device owned by the machine, coupled to at least one of the members belonging to said dosing devices and dispensers involved in the drive movement and action of each of them,
• said at least one dosing device being at least one liquid fertilizer dosing device and said dispenser being a liquid dispenser.
