ABSTRACT:
An apparatus and manufacturing method in which from one to three hydraulic pumps are provided and installed near a front end of the implement, so that a first pump can be easily coupled to the power take-off shaft of the tractor by an operator. In an exemplary embodiment of a system for a planter apparatus, one pump supplies pressure and flow to a hydraulic circuit for operating the vacuum fan subsystem, and optionally a fertilizing subsystem. A second pump supplies pressure and flow to a hydraulic circuit for operating the seed drive subsystem. A third pump supplies pressure and flow to a hydraulic circuit for operating a bulk fill subsystem. A manufacturing method that provides multiple configurations is also disclosed.
