Disclosed is a system for distribution of granular salt or brine from a vehicle. The system includes an auger assembly of a pair of powered independently rotating flighted auger sections disposed in an auger box and receiving salt stored by the vehicle. Each auger assembly has a discharge end surrounded by a choke fitting closely thereto and located at opposite ends. The system also includes a pair of powered spinner assemblies. Each spinner assembly is located beneath an auger discharge end for receiving salt from each auger assembly. Each spinner throws salt operates independently and rotates in an opposite direction. When salt is to be thrown from only one of the spinner assemblies, both of said auger assemblies rotate in the same direction for feeding the spinner assembly that is throwing salt. Nozzles directed onto each operating spinner assembly sprays brine thereonto.
