Abstract: The invention provides a system, device and method that can control the rates of seed dispensation and fertilizer application as a function of forward speed as well as across all rows. Thus, the system and control device allow control of each individual row unit, whereby dispensation and application are effected, by a central controller which controls a plurality of pulse width modulation valves, each of which controls a hydraulic motor with an integrated rpm reduction and which drives a stub drive shaft which rotates at the proper speed in order to provide the desired seed and fertilizer metering. Each of the stub drive shafts may rotate at completely different speeds and/or may be shut down while the remaining stub drive shafts rotate at the desired speed. The integrated rpm reduction within each hydraulic motor allows very fine rotational control of the dispensation and application rates.

Abstract: A method of automatically planting two or more seed types with an agricultural planter includes monitoring a planter location on a prescription map of an agricultural field. The planter includes one or more remotely adjustable planting characteristics. A seed type is selected based on the monitored planter location on the prescription map, the seed type including two or more seed types. The selected seed type is dispensed to one or more seed metering systems of one or more row units based on the selected seed type. As the planter moves in the agricultural one or more of the remotely adjustable planting characteristics of the planter field is dynamically changed based on at least the seed type selected according to the monitored planter location.
