The SF 90-100 HT is particularly light due to the materials used in its construction. Protection against overload is provided by cut-out clutches in the cutters and a shear bolt coupling in the cardan shaft. Thanks to the revolving impeller housing the snow can be directly ejected sideways. The centre of gravity and the weight have been dimensioned in such a way that the attachment guidelines and thus the axle load of the carrying vehicles can be complied with. The ejection chute tilt has been optimised to the extent that the front overhang can be maintained starting from the centre of the vehicle steering wheel. Owing to the standard hinged scraper blade, hindrances such as protruding manhole covers can be driven over without major problems.
