TEDDING (EN: agitation; DE: Wenden; FR: remuage, agitation; ES: agitacion, removido; RU: ворошение) is the technological operation, which is including the overturning of the milled peat crumbs, which are located within the thin layer, for the acceleration of their drying. They perform the tedding using the trailed peat tedders. The effectiveness of the tedding (the relative decreasing of the time of the drying) depends on the weather, on the frequency of the overturning, on the thickness of the layer of the milled crumbs, on the status of the surface of the peat deposition, on which the layer is situated, and so on. They usually conduct the tedding during the day time (1-2 times); in case of the two-day prolonged drying, they conduct the tedding 2-3 times; in this case the speed of the drying (in comparison with the drying without the tedding) increases by 25-40%. The first tedding is performed at the time of not earlier than 3-4 hours of the drying after the milling of the peat deposition, and they conduct the last tedding at the time of 3-4 hours before the harvesting of the peat.
