1.4 Description of the POLARO

®

The 

POLARO

® 

 is a spreader for spreading winter salt, grit, sand and granulated fertilisers. It consists of a solid

frame, a hopper for the material to be spread and the electrical components.
The frame includes the spreading disc with slider/dosing equipment. The electrical components comprise the drive

motor, speed sensor, distribution control box, control console cable, control cable, battery cable, control console and

breakaway safety cut-off.
A separate motor drives a slow-running agitator for grit, sand, smooth flowing salt or granulated fertiliser. As an

alternative for slow-flowing or damp salt, a special saline agitator is available as an accessory. This agitator is

mounted in an upright position in the hopper.
The speed of the spreading plate and disc can be regulated from a control panel in the driver's cab.

Notice

The 

POLARO

®

 can be mounted on the front or rear of the carrying vehicle.

Note the gross weight of the filled spreader.
