ABSTRACT:
The invention provides an innovative yet straightforward approach to driving the seed distribution system in planters which feature hinged winged extensions. The flexibility of the hinged winged extensions may allow the planter to adjust to the contours of a field and to fold to facilitate transport of the planter. In one embodiment, for example, the invention may provide a mechanical coupling between several sections of a seed drive shaft which may support and be driven by a hydraulic motor for each of the winged sections. The seed drive system may also be coupled to row units to synchronize and power the distribution of seeds by the planter.
