Flexible suspension of colter element () of a snowplough furnished with a body (), a blade () as its extension, colter element () that gets in contact with the surface to be ploughed, where for the colter element () a tilt suited for the purpose is arranged, a.o. a cutting angle. Colter element () is fitted to dodge an obstacle in its cutting angle by backing up, whereby the fixing arrangement of colter element () has an open space formed for moving plate () fitted as extension of the colter element, in which space said moving plate is arranged to glide, and the arrangement includes a spring organ () the spring impact of which is arranged to hinder the colter element from backing up.

Blade element mounting in a snow plough

A blade () meant to work in the curved form of a snow plough and attached from its lower edge to a rigid beam, the upper edge of which is supported by means of upper beam () or similar, and said blade is of flexible material, as plastic sheet. The blade is from its upper beam (), essentially from its middle, supported by suspension means (), which due to the ploughing load allows upper beam () and blade () upper edge to tilt and blade () to change the radius of curvature at least from the suspension spot on the blade area toward the blade point.
