Abstract
Data is collected from sensors related to the opener assembly for seeders, such as for discs and hoe drills, in order to better determine how the opener assembly reacts while operating in various conditions and to more precisely control operation of the opener assembly. Accordingly, a control system and a sensor array are utilized to provide automatic and continuous down pressure adjustments (according to a certain user specified range) at various speeds to substantially maintain a relatively constant seed depth. The sensor array could also be monitored and controlled by an operator to control settings (such as with respect to seed depth and/or opener down pressure) of the seeding implement from the cab to provide manual down pressure adjustments at various speeds. In various aspects, seeding speed and/or tractor speed may also be parameters controlled via the sensor feedback according to a certain user specified range of sensor variation.
