Implements of husbandry/agricultural equipment operations include the transport of commodities and equipment from the field sites to farmsteads, storage facilities and gathering points for movement by mass transit systems. Equipment often moves between farmsteads and field sites that are not contiguous. Transport may involve moving on public roads (infrastructure) that permits faster ground speeds than that which is used in the fields or within the design considerations of the equipment. Design approaches have been identified to permit selected equipment to move at faster ground speeds in transport configurations. This standard provides a means of identifying equipment that has been specifically designed for ground speeds greater than 40 km/h (25 mile/h) but under 65 km/h (40 mile/h), when operating or traveling on public roads. The means of identification is a Speed Identification Symbol (SIS).
