The models differ only in how they spread.
Mod. SASS
Salt and sand spreader ideal for agricultural tractors, on which it is mounted via a three-point attachment. The material is spread by dropping and therefore the working width depends on the width of the hopper. The hopper feeder is powered by a hydraulic motor.
Spreading is regulated by a mechanical device by varying the wheel pressure on the guide roller. By modifying the rotation speed through the regulation of an oil flow control valve, the material is distributed more densely. The steel structure is painted with an epoxy rust-proof paint undercoat plus a bi-component enamel paint.
In the self-loading models, the material is conveyed into the hopper by a hydraulic cylinder which places the bucket horizontally. The operator drives the tractor to the sand pile to be loaded, and then when the cylinder is removed, it returns to the original position.
