  • Patent number: 4718183
    Abstract: The present invention relates to a snow tiller for rearmounting on a track maintenance vehicle. The snow tiller comprises a transmission for driving at least one tiller shaft, a carrier frame for mounting the snow tiller on the track maintenance vehicle, and a baffle body of trapezoidal cross-section extending over the width of the snow tiller. A levelling attachment is secured to the underside of the baffle body facing the track surface.With a view to facilitating repair and maintenance operations and replacement of wear components, the baffle body is formed as a tubular profile member forming a central tiller frame. The transmission is mounted at the center of the tiller frame and drives to tiller shafts laterally connected to the transmission. The ends of the tiller shafts facing away from the transmission are mounted in outer bearings secured to the ends of the tiller frame.
