1.3 Description of the POLARO®

The POLARO®is a spreader for spreading de-icing salt, grit, sand and

granulated fertiliser. It consists of a solid frame, a spreading material

hopper and the electrical components. The spreading disc with slide/

dosing device is part of the frame. The electrical components include

the drive motor, speed sensor, distribution switch box, control panel

cable, control cable, battery cable, control panel and automatic

spreader-bar release.

A separate motor drives a slow-running agitator for grit, sand, free-ﬂowing

salt or granulated fertiliser. For salt that is moist or not free-ﬂowing, there

is a special agitator for reﬁned salt which is available as an alternative

accessory. The agitator is ﬁtted vertically in the hopper.

A control panel regulates the speed of the spreading disc and the slide

from the driver's cab.

The POLARO®can be attached to the front or the rear of approved

carrier vehicles.
