ABSTRACT:
A spreader to be mounted on a vehicle. The spreader has a main container to hold a particulate material and an outlet for a particulate material. The particulate material can be dispersed from the outlet and there is an electric motor adjacent the main body to drive the particulate material from the body. This electric motor has a drive shaft that extends to an outlet. There is a feeder, for example a screw conveyor, on the drive shaft to force the particulate material from the outlet when the shaft rotates. The spreader includes seals to prevent leaking of the particulate material from the body when the shaft is not rotating and also has the ability to warn when the level of particulate material in the main body is too low.
