Abstract
A system for handling agricultural chemicals, such as herbicides, pesticides, and the like which are supplied in dry form. A refillable tank includes an integral, internal auger that horizontally extends through the bottom portion of the tank and is adapted to feed dry chemicals from an outlet in one side of the integer auger, and an internal flow regulating system for apportioning the chemical into the auger. The internal tank auger is driven by a detachable drive motor which is connected to the drive end of the internal tank auger. A feeder hose having a flexible, internal auger detachably connects to the outlet end of the internal tank auger by a cam lock coupling provided on one end of the feeder hose and on the outlet end of the internal tank auger. An auger coupling extending from the cam lock coupling end of the feeder hose mateingly engages the internal tank auger when connected. A drybreak assembly connects the feeder hose with a planter hopper box for later dissemination.
