Abstract: A vehicle-mounted spreading apparatus includes a container for the material to be spread, at least one spreading disc rotatable about a vertical axis and a dosing device for conveying material from the container to the spreading disc as the vehicle moves along the ground. The disc and the dosing device are powered from a driving wheel which can be lowered into driving contact with the ground. The driving wheel conveys power to a mechanical power transfer assembly which drives the dosing device and which drives an adjustable speed motor system for the spreading disc.

Abstract: A vehicle with apparatus for discharging material such as salt on a roadway or the like at a rate that a control system automatically varies with vehicle speed includes means that ordinarily interrupts normal control to prevent discharge of material while vehicle speed is below preselected threshold value. The system also includes a blast circuit which responds to momentary manual operation of a switch to impose a blast signal on control system to override all other control activity to cause rapid dispensing of material for a preselected period even if vehicle is stopped or moving below the threshold speed.
