Special drive system that provides automatic application control of granular material

A special drive system that provides an automatic application control of a granular material from a granular material spreader, the spreader including a hopper, a conveyor and a spinner device with a means for spinning at a desired speed and the said special drive system is comprised of:

• (a) at least one electric motor for driving the conveyor and spinner at a speed, the said speed which determines a rate of discharge of the granular material;
• (b) a power source for the motor;
• (c) a means for controlling the power from the power source to the at least one motor;
• (d) a means for inputting a signal to the means for controlling the power;
• (e) a wiring harness with control and power electrical connectors;
• and
• (f) a means to mechanically mount the special drive system to the grain spreader
• wherein the result of the system is an accurately controlled rate of discharge and hence dispensing of the granular materials.
