The S 3.1 is equipped with a 1.50m wide feed plough that deflects the snow to the blower wheel, giving a consistent clearing result over a width of 2,000mm. The widely projecting tips of the four-bladed blower wheel ensure perfect snow pick-up even when the snow is thin.
The S 3.1 is driven by a chain drive directly connected to the PTO shaft of the carrier vehicle via a Cardan shaft. A shear bolt on the connecting flange to the blast wheel protects the machine in case of contact with unforeseen obstacles.
With the S 3.1, snow can either be ejected over distance or loaded onto trucks, while the blower wheel housing is hydraulically adjustable left or right. With the hydraulic slewing ring, the discharge chute can be rotated through 360°. A pre-cutting propeller is mounted on the throwing wheel to loosen compacted snow and is protected against damage by a shear bolt. A pre-cutting propeller is mounted on the blower wheel to loosen extremely hard snow.
The S 3.1 has a quick-change device for speedy mounting on the unit plate of the carrier vehicle so it is ready for use in a very short time. As it is directly driven via the PTO shaft, no further drive is necessary. The S 3.1 is suitable for the Unimog carrier vehicles: U 300, U 400, U 500 and the U 900 to U 1600 series, plus a variety of other carrier vehicles.
